MAL9000AXX Whirlpool LP Gas Conversion Kit is a factory replacementā£ kit designed to convert specific āWhirlpool gas cooking appliances from natural gas to ā¤liquefied petroleum (LP) fuel. The kit typically contains āreplacement burner orifices ā(jets), regulator adjustmentsā or springsand associated seals or fasteners required ā£to alterā fuel delivery characteristics. As āa componentā groupā rather than aā¢ singleā moving part, it provides the calibratedā£ hardware āneeded to adapt an appliance’s gas metering systemā to the different pressure āand energyā¢ density of propane.
Inside ā£the appliance the ā£conversion ākit directly affects the gas delivery and combustion subsystems: the burner orifices change the volumetric flow into the burnerā£ ports,and the regulator/spring elements adjust downstream pressure and valve response so that the āfuel/airā ratio remains within safe and efficient limits. āThe kit thus interfaces with theā appliance gas shutoff valve, manifold, ignition and flame-sensing systemsand the ā¢combustion chamber; improper or incomplete conversion can produce poor āignition, unstable flames, sootingor unsafe combustion and must be verified by pressure testingā and flame inspection after installation.
In āthis article readers will findā£ a technical examination of the ā¢MAL9000AXX kitā including its constituent parts and intended appliance models, a clear explanation of how conversion changes orifice sizing and regulator settings, common symptoms ofā¢ incorrect conversion orā component failure, step-by-step troubleshooting ā¢and verificationā£ methods (including pressure checks andā leak tests)and practical ā¢considerations for safe replacement such as required tools, torque and sealingā practices, labelingand compliance with local ā¢codesā and manufacturer instructions. The objective ā¤is to provide technicians, engineersand informed appliance owners with the technical context needed to assess compatibility, perform or evaluate a conversionand confirm correct operation postāinstallation.

Function and Role of theā Conversion Kit in LP ā¤Gas Delivery and Appliance Safety Controls
MAL9000AXX Whirlpool LP Gas Conversion Kit contains the specific mechanical parts and calibrated components required to convert a Whirlpool gas appliance from natural āgas toā liquefied petroleum (LP) operation. The kit typically provides smaller burner orifice spuds,ā£ a spring or insert ā¢for the pressure regulatorand any necessary seals or mounting āhardware; these items change theā fuelā¤ meteringā¤ and āregulator behavior so that the appliance āreceives āthe ācorrect manifold pressure and fuel flow for LP. Correct orifice sizing and regulator adjustment compensates for propane’s higher energy density and higher āvapour pressure relativeā¢ to naturalā gas, preventing over-fueling, flameā¢ liftingor incomplete combustion that would affect burner stability and safety āinterlocks āsuchā as thermocouples and flame-sensing devices. Compatibility is model-specific: the MAL9000AXX kit is intended for designated ā£Whirlpool ranges and must be matched toā£ theā¢ appliance model ā£number and burner types listed in the kit documentation.
Converting an appliance alters several safety-controlā£ andā£ performance parameters that technicians must verify after installation.ā¤ Theā£ pressure regulator settingā¢ determines manifold pressure (LP appliance targets aroundā 10″ WC)and ā¤burner orifice sizeā determines combustion rate and flameā geometry, both of whichā¤ affect thermocouple heat and āthe response of safety shutoff ā¤valves and electronicā¤ flame detection. Practical post-conversion ā¤checks include leak testing of all gas connections, visual inspection of flame shapeā and color under low and high settingsand temperature āchecks of theā oven or ācooktop against the appliance calibration. Technicians shouldā also apply the conversion label to the appliance data plate andā record the change in service documentation to ensure ā¤future parts and service align with LP configuration.
- Change orificeā¢ spuds and ā¤install regulatorā parts from the kit
- Perform gas-leakā test and regulator/manifoldā¤ pressure measurement
- Confirm stable low/high flames and proper āthermocouple/valve behavior
- Update appliance data plate and record conversion details

How the MAL9000AXX whirlpool ā¢LP Gas Conversion Kit Works Inside the appliance
the MAL9000AXX Whirlpool LP Gas Conversion Kit adapts a whirlpool appliance’s fuel delivery and combustion components so theā¤ burner assembly āoperates correctly on propane (LP) instead of natural gas. Inside the appliance the kit replaces the main burner orifices with smaller-diameter orifices sized for the higher energy density and supply pressure of LP, ā£and provides a regulator ā£adjustment or conversion cap to set the manifold pressure appropriate for propane. These internal changes alter the air-fuelā ratio ā£and flow characteristics at each burner and at the pilot, so the kit also includes or references adjustments to air shutters and burner alignment to achieveā a stable, ā£blue-flameā combustionā¢ pattern withoutā¢ excessive soot or ā¢flame lift.
- orifice replacement to āmatch ā¤LP volumetric flow requirements
- Regulator conversion or adjustment toā£ set higher LP manifold pressure
- Pilot or thermocouple check to ensure reliable ignition andā¢ safety shutoff
- Labeling āandā¢ model-specific compatibility verification for the receiving appliance
When installed by a qualified technician, ā£the conversion alters manifold pressure and burner flow but does not change the appliance’s temperature control logic; thermostats and electronic controls continueā¤ to operate while the actual heat input āper burner ā£increases, so calibration checks (temperature rise tests, broil/oven temperature checks) are recommended afterā£ conversion. Post-installation verification should include aā leak test, visual flame inspection on all burnersand measurement ofā£ manifoldā¢ pressure and, where available, combustion gas composition (CO/CO2) to confirm efficient combustion. Theā¢ kit āis intended for specificā£ Whirlpool models; āconfirm the appliance model number against āthe kit’s compatibility list and replace any incompatible seals or fittings that could affect pressure integrity or safety.
| Item | Description |
|---|---|
| Orifice size | Smaller diameter āfor LP to reduce ā¢volumetricā flow while maintaining energy input |
| Manifold pressure (typical) | Natural gas ā 3.5″ w.c.; LP (propane) ā 10″ w.c. – regulator must be set accordingly |
| Safety check | Verify pilot/thermocouple response, perform leak testā¤ and combustion verification after conversion |
Common Failure Symptoms and Diagnostic Tests for ā£Conversion Kit Malfunctions
the MAL9000AXX Whirlpool LP Gas Conversion Kit changes orifice sizes and regulator settings so an appliance designed for natural gas will operate safelyā£ on LP (propane); if the kit āis installed incorrectly āor is incompatible with a specific Whirlpool model, symptoms appear ā¢as altered flame behavior,ā£ ignition failuresor poor heat output. Techniciansā should evaluate flameā¢ color and pattern (a stable blue envelope versus lifting, yellowor sooty āflames), ā¤check for repeated pilot outage or intermittent burner ignitionand confirm that the installed orifices, regulatorand jet sizes match the appliance serviceā£ manual for the model. Compatibility issues ā¤also present as excessive burner noise or regulator chatter; these indicate incorrect inlet pressure, wrongā jet sizingor a regulatorā that cannot hold the higher LP working pressure required by the appliance design.
Diagnostic testing consists āof functional observations combined with quantitative checks: use a manometer to record ā¤static and dynamic manifold āpressure while burners are operating,ā perform āaā¢ soap-solution leakā¢ test at conversion kit fittings and hose connections, verify orifice āID markings against the kit ādocumentationand measure thermocouple output or igniter continuity as appropriate. For example, if burners light but heatā¢ is low andā flames are very small, remove and inspect the LP jets for clogging or incorrect size, āthen confirm pressureā under load with the āmanometer; if the manifold pressure matches the kit specification but flow is insufficient, suspect blocked lines orā¢ partially closed valves. Follow the applianceā manufacturer’s conversion instructions and diagnostic flow (visual, leak,ā¤ pressure, component electrical checks) to isolate failures before replacing parts.
- Yellow or lifting flames – check orifice size and cleanliness, confirm correct LP jets installed.
- Ignition clicks but no flame – verify gas valve solenoid continuity, measure pilot/igniter voltage, āand confirm gas flow to pilot.
- Intermittent heating or āregulator noise – perform dynamic manifold pressure test and inspect regulator venting and mounting.
- Gas smell after conversion – immediate leak check at all kit fittings and āsupply connections; shut off supply until repaired.

Compatibility,Replacement Considerations,and Installation Verification for Affected Whirlpool Models
The MAL9000AXX Whirlpool LP Gas conversion Kit ā£adapts selected Whirlpool gas rangesā£ and ovens fromā¤ natural gas to propane by replacing burner orifices,providing the correct ājets and regulator calibration components,and supplyingā the hardware needed to maintain safe combustion characteristics.ā Conversion alters volumetric flow and required manifold pressure: LP āuses smaller āorifice diameters and aā higher manifold pressure ā£than naturalā¤ gas, so confirm compatibilityā¢ with the appliance’s gas valve family and control assembly before installing the kit. Verify the appliance ā£model and gas valveā part number against the kit request list; some Whirlpool units with non-standard pilot assemblies orā aftermarket valves ā¤will not accept the kit āwithout additional adapters or ā£choice parts.
When replacing parts, inspect the gas valve ā¢for stamped identification and confirm orificeā thread ā£form and seating depth to prevent leaks or poor flame shape. After installation ā¢perform aā£ leak test, measure manifold pressure with aā manometer at lowā and high fireand observe flame morphologyā across settings – LPā¢ flames should be short, blueand centeredā£ on the burnerā cap; lifted, noisyor orange-tipped flames indicate incorrect orifice size, regulator setting, āor combustion ā¢air. Also verify flame-sensing devices (thermocouple or flame rectification electrodes) āregisterā properly and āthat the regulator vent and pilot assemblies are oriented and secured per the kit instructions before returning ā¤the appliance to āservice.
- Confirm model/serial and gas valveā£ part number match kit documentation.
- Install āsupplied orifices and regulator components; torque to specified values.
- Perform a pressureā¢ measurement withā¢ a manometer at idle ā£and at maximum burnerā input.
- Conduct a gas leak test on all joints and check flame shape āacross low-to-high.
- Validate flame sensing and safety shutoff operation duringā¤ multiple cycles.
