WE25M74 GE Washer Dryer LP Gas Conversion Kit is âa factory service kit designed to adapt a GE⢠washer-dryer appliance’s gas-fired drying section from natural âgas to âLP (liquefied petroleum) âfuel.The kit isâ a collection of fuel metering and pressure-matching components-typically including correctly â˘sized orificesâ or jets, regulator or regulator adjustment âparts, fittingsand related sealing hardware-specified to change âŁthe appliance’s fuel delivery characteristics so the burner receives â˘the appropriate volume âand⣠pressure of LP gas.
Within the appliance, the⤠conversion kit interfaces âdirectly with⣠the gas supplyâ train⣠and the burner assembly and thus â¤interacts with â˘the gas âvalve,â pressure regulator, ignition⤠system (spark orâ glow igniter), burner portsand safety controls such as flame âsensing and thermal cutouts. By alteringâ orifice size âŁand pressure settings, the kit ensures⣠correct air-fuel ratio and heat output for stable⣠combustion; incorrect conversion or omitted components can â¤lead to poor burner â˘performance,⣠increased soot, incomplete combustionor safety risks.Its proper application is therefore essential to â¤maintain designed âheatâ output, appliance⣠control â˘interactionsand â¤safe exhaust characteristics when âthe fuel⤠type is⢠changed.
This âŁarticle explains theâ WE25M74 kit’s intended function, âŁhow to confirm compatibility with specific⤠GE washer-dryer model numbers and âŁservice manuals, commonâ failure symptoms âŁthat âindicate conversionâ or metering issues (for example weakâ or inconsistent flame, soot, gas odor,â or drying performance loss), diagnosticâ checks a technician should considerand factors to weigh when replacingâ or reinstalling â¤the kit components. The content focuses âon component function, compatibility verification, symptom identification, troubleshooting considerationsand installation-related precautions âto aid technicians, engineersand appliance â˘owners in making informed service decisions without substituting â˘for the appliance manufacturer’s installation instructions and safetyâ procedures.

Functional Role of the LP Gas Conversion Components in the WasherâDryer⣠Fuel and Ignition âSystem
The âWE25M74⣠GE washer Dryer LP âGas Conversion Kit provides theâ specific âorifices and regulator adjustments necessary âto adapt the appliance’s fuel train from âŁnaturalâ gas to propane (LP).In technical terms,⣠the conversion components change the effective âŁpassage area and downstream pressure âŁso the burner receivesâ theâ correct volumetric â˘flowâ for the⤠higher energy density of âLP⢠fuel. These â˘components â˘- typically main burner orifices, a⤠pressure regulator or â¤regulator cap changeand â¤associated seals or adapters – work together to preserveâ the designed airâfuel ratio and flame geometry so that the ignition system â˘(spark or hot âsurface ignitor) and âflame-sensing devices operate within expected parameters after âconversion.
Functionally, the conversion piecesâ control steady-state and transient behaviors: the orifice size limits peak gas â¤flow, the regulator establishes⣠the⢠target âmanifoldâ pressure under⣠loadand nozzle or pilot adjustments stabilize pilot flame for reliable ignition. âŁIf âany âŁelement⤠is⣠mismatchedâ or installed incorrectly,⣠symptoms can âinclude⤠orange/yellow âflames, soot buildup, delayed ignitionor nuisance safety shutdowns. Technicians should verify â¤part compatibility âŁwith⢠the appliance model,⤠measure manifoldâ pressure with aâ manometer after installation, perform âŁa leak âŁcheckand⢠observe burner appearance under normalâ and high-load cycles⤠to âŁconfirm that the ignition sensors see a⤠stable flame.
- Main burner orifices – reduce orifice diameter âto match LP volumetric flowâ requirements.
- Pressure regulator adjustment – sets proper⣠manifold pressure for propane operation.
- Pilot/nozzle components â- ensure stable pilot for consistent ignition âand sensing.
- Gaskets/labels/instructions – provide sealing and model-specific installation guidance.

Howâ the WE25M74 GE Washer Dryer LP Gas â˘Conversion Kit interfaces with Burners, Valvesandâ Control Electronics
The WE25M74 GE âŁWasher Dryer LP Gas âConversionâ Kit contains the mechanical componentsâ required to adapt the appliance’s gasâ supply from natural gas âto liquefied petroleum⤠(LP) andâ interfaces directlyâ with burner â˘ports and the manifoldâ upstream of the gas valves. The kit âtypically includes smaller LP orifices, a pressure regulator or pressure-setting shimsand pilot orifice changes; installing these⤠components reduces the âcross-sectional area at âeach â¤burnerâ andâ lowers manifold pressure â˘so the flame geometry and heat inputâ remain within design limits. Whenâ fitted,the orifice and regulator alter volumetric and velocity characteristicsâ at the burner âthroat,which changes flame length,temperature distribution,and the air-fuel mixing regime; technicians â˘must verify that the burner⢠ports and primary air openings are compatible with the new â˘orifice âŁsizes to avoidâ flame lifting,flashing,or incompleteâ combustion in âconfined passages.
The conversion kit âdoes ânot⣠normally modify theâ appliance’s control electronics or valve actuation signals,but⤠it does â¤change how⣠theâ gas system âŁresponds to those⤠signals. Gas valves remain the electrical actuators; the kit changes the downstream flow characteristics while the control â¤board continues to âŁcommand the valve coil at the same voltage and timing. â˘Practical checks after conversion include confirming the valve coil voltage rating matches the existing coil,⣠verifying the regulator⢠is set to âthe expected⢠LP manifold âpressure (typical⤠LP manifold âpressures in small appliances are⢠on the order of â10-11 in. WC), observing âflame â¤stability across âthe âfull heat rangeand confirming flame sensing (thermocouple, thermopileor ionization⤠sensor) still registers⢠reliably. Perform â˘a leak test and combustion check (CO and combustion efficiency) after installation to ensure âthe⢠mechanical changes introduced by the kit âŁdo not âcreate unsafeâ combustion or control faults.
- Key installation and verification steps: install LPâ orifices â˘and regulator, set manifold pressure, verify valve⤠coil voltage, observe⤠flame shapeâ at⤠low/medium/highâ settings, â˘perform leak and combustion tests.
| Item | Description |
|---|---|
| Orifice | Smaller orifice sizeâ reduces flowâ for LPâ and changes jet velocity and mixing at the burner port. |
| Regulator | Sets lower LP manifold pressure so downstream flow â˘matches âappliance design points. |
| Gasâ valve / coil | Valve body remains the flow control device; â˘coil voltage/timing must remain compatible with control electronics. |
| Flame sensor | Thermocouple/ionization/thermopile must detect reliable â˘flameâ with theâ new flame geometry; verify operation. |
Common⢠Failure Symptoms: Leak Indicators, Ignitionâ Failures, Flame⤠Instability, â¤and Diagnostic âCodes
The WE25M74 GEâ Washer Dryer â˘LP Gas Conversion⤠Kit replaces⣠key âgas-delivery componentsâ (orifices, regulator âspring/adjustmentand associated âfittings) so⢠the dryer can operate safely on propane instead of natural gas.If the kit âis missing, installed incorrectlyor not âmatched to⢠the precise âmodel, the burner âassembly can exhibit leak indicators, ignition failures, âand flame instability caused âŁby mismatched⤠orifice sizing, incorrect regulator settingsor compromised seals. Practical⤠examples include a persistent hissing at a joint after â˘conversion (indicating a seal or fitting issue)or a consistently yellow, sootyâ flameâ after â¤conversionâ that⣠points to anâ overlyâ rich mixture caused by the wrong orifice or insufficient primary air.
- Leak⣠indicators – audible hissing, detectable propane odoror soap-bubble response at joints.
- Ignitionâ failures – no spark or glow, â˘continuous sparking without flameor repeated âlockouts âŁafter delayed ignition.
- Flame instability – yellowâ tipping, lifting, flutteringor â˘soot accumulation on the burner and heat exchanger.
- Diagnostic codes /⤠control behavior – service lockouts, repeated errorâ displaysor fault LEDs that correspond toâ ignition or gas valve â¤faults in the service manual.
| Item | Description |
|---|---|
| Leak indicator | Hissing or âsoap-bubble response at â˘fittings; isolate⤠gas and test with approved leak detector before further diagnosis. |
| Ignition failure | Igniter or spark module âfault,weak⤠valve solenoid,or incorrectâ manifold âpressure – verify igniter continuity andâ valve actuation. |
| Flame instability | Incorrect orifice/regulatorâ setting or restrictedâ combustion air; inspect orifice âsize and burner ports,â and verify ventilation. |
| Control/diagnostic response | refer to the model⢠service â¤sheet for code-to-fault âŁmappings; repeated lockouts often indicate flame sensing or gas flow issues. |
For practical troubleshooting,follow a methodical sequence:⣠isolate the gas supply,perform a leak test on all joints and the conversionâ fittings,verify that the installed orifices and regulator spring match the WE25M74 GEâ Washer Dryer LP Gas Conversionâ Kit specifications,and measure manifold pressure withâ a manometer to confirm it meets the conversion documentation. Test âelectrical components next – confirm igniter resistanceâ and cycle timing, check⣠flame sensor âcontinuity and voltage to the gas âŁvalve⣠coils during a start âsequence,â and inspect venting and combustion air paths because restricted airflow⢠amplifies flameâ instability. Replace worn seals,⣠useâ OEM conversion parts,⤠and consult the dryer’s technical sheet forâ model-specific⤠diagnostic codeâ definitions before â˘replacing major assemblies.
Compatibility and âSupported GEâ WasherâDryer Models, Serial Ranges,⣠and Required Fuel Pressure Specifications
The WE25M74 GE Washer Dryer â˘LP Gas Conversion Kit supplies âthe⣠orifice replacements and regulator adjustments âŁrequired to âŁconvert compatible GE washerâdryers from natural gas to LP âŁ(propane).Converting involves reducing orifice diameter and modifying the regulator spring â¤or cap so the burner â˘receivesâ the correct manifold pressure and maintains an appropriate âairâfuel ratio; incorrect orifice sizing or⤠regulator⢠setting will produce weak flames,⢠sootor â¤incomplete combustion. Typical â¤target manifold pressures are about 11″ WC (27.5 mbar) for âLP and about 3.5″ WC (8.7 mbar) for natural âŁgas, butâ technicians⣠must confirm theâ exact values shown on the appliance data tag before making adjustments.
Confirm compatibility by matching the unit’s âŁmodel and serial number â¤on theâ service tag to the⤠conversion kit’s documented âserial ranges; the tag is usually âlocated on the dryer door frame or rear access panel. â¤Follow a â¤short verification and commissioning sequence:
- locate andâ record model/serial on âtheâ data plate,
- verify the kit number andâ parts match the documented serialâ ranges,
- install orifices and adjust regulator per instructions,
- perform a manifold âŁpressure âŁtest âŁand observe flame pattern,
- perform a gas leak and combustion check before returning âto âservice.
| Item | Description |
|---|---|
| LP manifold⢠pressure | Typically ~11″ WC (27.5 mbar); set⤠to âvalue on appliance tag |
| Serial tag location | Usually on â¤the dryer⤠door frame âor rear âaccess panel; requiredâ to confirm kit applicability |
Replacement Considerations and Installation: Part Interchangeability, Seals,⣠Torqueand â˘Gas Safety â¤Procedures
The ⤠WE25M74 GE Washer Dryer⢠LP Gas âConversionâ Kit contains the partsâ required âŁto adapt the appliance’s gas train for propane âŁ(LP) service,⤠typically including orifice(s), regulator adjustmentsand replacement gaskets or seals. When considering â¤partâ interchangeability,verify that the kitâ matches theâ appliance model and â˘the valve/manifold thread form; some valvesâ use unique âŁorifice sizes or mounting⣠geometries that âare not compatible with other model families.⢠Swapping âorifices or using an improvised fitting can change fuel âflow and pressure characteristics, producing⤠incomplete combustion, flame âŁinstabilityor safety shutoffs.â For technicians,â match the⤠kit part numberâ to the âwasherâ dryer serial/model, inspect the valve and burner ports for wear or damage,â and replace any gasket, seator â¤Oâringâ that shows compression set or cracking beforeâ reassembly to preserve predictable flow âand âsealing⤠behavior.
Seals âandâ mechanical fastening directly âaffect leak integrity and combustionâ safety. Use only gasârated⣠sealants or PTFE tapeâ applied inâ theâ direction âof â˘thread âengagement â˘and avoid overâapplication that can foul valves â˘or orifices; replace soft âseals with OEM materials where specified. Fasteners and fittings must be tightened to⤠the appliance manufacturer’s torque specifications with a calibrated wrench because both â˘underâ and overâtorquing âŁcan⢠produce leaks or damage â˘sealing faces-if âthe spec is not available, consult the valve or fitting manufacturer’s âdata rather than guessing.After installation perform âŁa static pressure check and dynamic leak â˘test (soapy solution or electronic leak detector)â at typical supply pressures, verify regulator outlet setting against⤠the applianceâ data plate (commonly around 10-11 in. W.C.â for LP appliances, confirm per label)and run the appliance through a burn âŁcycleâ to⤠confirm stable flame appearanceâ and no CO rise.
- Verify kit/model â¤match and inspect valve threads and âŁports before install
- Replace all âŁseals and gaskets included in the kit; use gasârated materials only
- Apply⣠thread âsealant correctly (clockwise wrap)â and follow torque specs or⤠manufacturer guidance
- Perform âleak testsâ and âregulator pressure checks; document â˘results
- Run a combustion âcheck and monitor⢠for âstable flame and⤠acceptable âŁCO levels
| Item | Description |
|---|---|
| Compatibility check | Confirm kit part number matches appliance model and valve typeâ before replacing â˘orifices or fittings |
| Seals | Use OEM or gasârated gaskets/Oârings; replace if hardened or compressed |
| Sealant | Gasârated pipe dope or PTFE tape applied correctly; âavoid⤠contamination of orifices |
| Pressure check | Verify regulator outlet and manifold pressures against data âplate âŁ(approx. 10-11â in. W.C. for LP, âŁconfirm⣠per appliance) |
Troubleshootingâ and Diagnostics: StepâbyâStep Pressure, Continuityand Leak⣠Tests for the LP Conversion Kit
The WE25M74 GE Washer Dryer LP Gas âŁConversion⤠Kit adaptsâ the appliance’s fuel-delivery⤠hardware – typically by changing burner orifices and configuring⢠the⤠regulator/spring assembly – âso the dryerâ operates correctlyâ on propane (LP) rather than âŁnatural â¤gas. The conversion changes the required manifold pressure and orifice flow area, so burners willâ have a⢠smaller âŁorifice and âŁa higher manifold pressure⢠setpoint than âŁon natural gas; incorrect⣠parts or installation will produce weak, sooty, â˘or yellow flames and unsafe operating conditions.â Verify model⣠compatibility with the appliance’s serviceâ data before installation because valve porting, regulator typesand pilot/ignitor arrangements âŁdifferâ between models and âdetermine which kit components⢠are required for safe operation.
- Isolate gas supply, depressurize the lineand âinstall a âmanometer or pressure âgauge at the â¤appliance â˘test port to record static inlet pressure andâ manifold pressure under load.
- Measure manifold pressure with the burner â˘or heating cycle running; âcompare to the conversion kit/service manual target values (see⣠reference table below).
- use a DMM âto perform⣠a continuity/coil â˘resistance check across gas valve solenoidsâ and⤠any⢠thermal cutoff â˘or control âswitches; an open circuit indicates âa failed coil or switch, while unusually high resistance suggests coil degradation.
- Performâ a leak testâ on all newâ fittings and connections using a âliquid soap solution or an âŁelectronicâ leak detector while âthe system is pressurized; bubbles or detector alarms identify âleaks that require tightening or replacement of fittings/gaskets.
- Observe flame â˘quality and combustion âbehavior during a run: a stable blueâ cone with minimal lift indicates correct pressure/orifice matching; â¤rounded yellow âtips orâ persistent sootâ indicate incorrect pressure, blocked orificesor improper âregulator selection.
Diagnostics shouldâ always reference the⤠appliance service specifications: measure both âstatic and operating pressures,⢠confirm electrical continuity of valves and safetiesand conduct a pressure-drop analysis âduring operation to detect internal regulator â¤orâ orifice faults. Such as, if manifold pressure readsâ below theâ LP target despite correct orifices, inspect the regulatorâ spring and seating and verify inlet supply pressure; if⤠continuity across a burner coil reads open, replace the valve assembly before attempting further â˘testing.Record readings and compare them to the service manual so correctiveâ actions â(or part replacements)⣠are based â¤on measured deviations rather than assumptions.
| Item | Description |
|---|---|
| Typical LP manifold pressure | Approximately 10″ WC (27 mbar) – verify exact value âin appliance service data |
| Typical âinlet/static pressure | Supply â¤dependent; ensure adequate supply pressure above manifold setpoint (example: 11-14″ WC under no flowâ for many âŁLP installations) |
| Coil/solenoid continuity (example) | Low-to-moderate resistance when healthyâ (tens to low thousands of ohmsâ depending on valve âŁdesign); open â˘or extremely â˘high resistance âindicatesâ failure |
Q&A
What⢠is the WE25M74 GE Washer Dryer LP Gas Conversion Kit and why would I âneed it?
the LP (liquid petroleum/propane) conversion kit lets âa GE â¤dryer âŁthat was factoryâset â¤for natural gas⣠be modified to run safely and efficiently on âLP/propane.You âneed it when you change your household fuel âfrom natural gas to âŁpropaneâ (for example after switching to bottled LP) so the burner receivesâ the correct fuel flow and pressure and the appliance burns âcleanly.
What parts are typically included in the âconversion kit?
Most conversion kits include the LP main burner orifice(s) (smaller jets forâ propane), any required regulator cap/spring or regulator parts, fasteners/parts to secure the new components,⢠detailed installation instructionsand a conversionâ label to place⤠onâ the appliance. Exact contents⣠vary by kit and model-always⢠verify the kit contents against the kit instructions before starting.
can I install⣠the LP conversion kit myselfor do I need a technician?
Because gas conversions involveâ fuel fitting changes, regulatorâ adjustments and combustion checks, manufacturers âand many local âcodes recommend a qualified service technician âperform the conversion.A licensed gas technician has the tools âand training to set manifold pressure,test for âŁleaks,verify safe combustion and comply with local code andâ warranty requirements. An experienced DIYer with proper tools and understanding of gas appliances could perform âtheâ conversion, but only if local regulations allow and the installer follows⤠the âmanufacturer⣠instructions exactly.
What are the basicâ steps â˘involved in converting⣠the dryer to LP (high level)?
Highâlevel steps âare: shut off â¤gas âŁand electrical power; access the burner assembly âand remove the natural gas orifice(s); install theâ LP orifice(s) supplied in the kit; install any regulator cap/spring or otherâ regulator parts ifâ required; replace any⢠seals or gaskets disturbed during the work; attach the conversion label; âŁrestore gas and electrical supply; âŁperform⣠a leakâ test on â˘allâ gas connections;â then run theâ dryer and check burner flame, manifold pressure and exhaust âto confirm proper combustion. Follow âthe kit and appliance service manual for detailed stepâbyâstep instructions.
Do I need âto adjust gas pressure or manifold settings after converting? What are âthe correct âpressures?
Yes-LP appliances require âa different manifold pressure than natural⢠gas and the regulatorâ or its internal parts are usually modified as partâ of the kit.â Typical âreference values (for â¤many âappliances) are roughly 3.5-4 in. W.C. for natural âŁgas and about 10-11 in. W.C. forâ propane, but these âŁare only general âguidelines. Alwaysâ measure manifold pressure with a manometer and set itâ toâ the exact pressure specified in⤠the âappliance service instructions â¤or on the kit label. â˘Never rely on approximateâ values alone.
How should I test the âdryer â˘after conversion to ensure it is safe and burning⣠correctly?
After conversion: 1) perform a⣠gas leak test at all connections with an approved leakâdetection solution âor electronic gas leak detector; 2) start⣠the dryer and visually âinspect the burner flame-proper combustion is a mostly blue flame â˘with minimal yellow tips and no heavy sooting;⣠3) measure manifold pressure with a manometer to âconfirm it matches the specification;â 4) check exhaust temperature and ventilation for normal operation; and 5) if available, check carbon monoxideâ (CO)â levels in the⤠exhaust toâ ensure they are within safe limits. If⤠you see â˘excessive yellow flames, soot, strong gas âodoror âŁelevated CO, shut downâ and call a qualified technician.
Will converting the dryerâ to LP affect my warranty or local code compliance?
Conversion can affect warranty coverage if not performed according â˘to⣠the manufacturer instructions or by an â¤authorized/service technician, so check your warranty terms. Additionally, âŁlocal building⣠and âgas codes may ârequire conversion to be âŁperformed by âaâ licensed professional and inspected afterward. Always verify local code requirements and retain documentation⤠of the âŁconversion and testing for warranty and inspection⣠purposes.
What common problems âŁshould I watch for after conversionâ and how â˘can they be⢠fixed?
Common issues include: sooty or yellow flames (indicates improper gas/airâ ratio or low âpressure-check orifice installation and regulator settings), gas odor or leaks (immediately shut off gas, ventilateand repairâ leaks), poor⢠heat or long drying â˘timesâ (could âbe incorrect orifice, low manifold⣠pressureor venting problems)andâ frequent cycling or flameouts (possible regulator or valve issue). Manyâ issues are resolved âby âverifying correct orificeâ installation, confirming â˘manifold pressure per specification,â checking ventingand performing combustion tests. If âŁproblems persist, contact a qualified technician to âinspect and correct adjustments.
