137524000 Frigidaire Washer Dryer âIgnitor is a replacement ignition component used in Frigidaire washerâdryer units that incorporate a gas dryer âfunction. Itâ is indeed a âheatâsource element-typically a hotâsurface or⤠glow ignitor-designed âtoâ provide the initial thermalâ energy required to igniteâ gas⣠delivered to the âdryer burner assembly.As a âŁdiscrete replacement part, it âŁincludes the mounting interface⢠adn electrical⤠connector required toâ integrate into the appliance’sâ burner module.
Inside âthe appliance, the ignitor âis part of the â˘gas ignition system and⢠interacts directly with the control board, gas valve, flame sensor or thermocoupleand safety limit switches. When the control boardâ calls for heat, it⢠supplies voltage to the ignitor so the element reaches ignition temperature; once the ignitor is hot,⣠the âgas â¤valve opens andâ the flame âis âestablished andâ monitored by the flameâsensing circuit. The ignitor’sâ thermal and⢠electrical characteristics therefore affect ignition timing, safety interlocksand overall heating performanceand its correct position and wiring are critical to reliable operation.
This article explains the ignitor’s functional role,â how to determine⢠compatibility and recognize equivalent part numbers, common⤠failure symptoms â¤such â¤as no heat or delayed ignitionand systematic troubleshooting steps including continuityâ and voltage checks. It also covers practical replacement considerations-safe gas shutoff, proper⤠mounting and alignment in the burner tube, connector âand harness inspectionand verification steps after installation-so⢠technicians, engineersand informed appliance owners can diagnose â¤and address ignitionâ issues effectively.

Function and Role of the Ignitor Assembly in âGasâ WasherâDryerâ Heating âControl
The â 137524000 Frigidaire â˘Washerâ Dryer Ignitor is a resistive hotâsurface âignitor used âto initiate combustion in gas âwasherâdryer⢠combinations. âDuring a ânormal⤠heat cycle the control board supplies voltage to the ignitor so it reaches a⤠high temperature⢠(visible red/orange)and once it is hot the gas valve is energized to⤠admit fuel; the ignitor itself âŁdoes ânot modulateâ the⤠valve but must reach â˘a specified temperature and resistance to allow the valve sequence to proceed. Compatibility depends âon physical mounting, âconnector âtypeand â¤the electrical characteristics (resistanceâ andâ operating voltage) required by the appliance control system, so⢠replacements should match these parameters ârather than being chosen solely âby external dimensions.
Technically, the ignitor is a sacrificial â¤highâtemperature resistor that commonly fails by developing âŁan open circuit, surface cracksor âinsulation breakdown that prevents it from reachingâ ignition temperature; it can also draw excessive current âif partially shorted, which⣠may trip safety cutouts. In practical â˘troubleshooting, technicians confirm absence of⢠visible glow, verify continuity⤠and supply voltage at the connectorand inspect upstream âŁsafety thermostats âŁand the gas valve sequence before replacing the ignitor. typical service procedures includeâ measuringâ resistance,â checking for supply â˘voltage during the start of⢠a heat cycleand confirming âcorrect mounting and⣠air/gas flow âŁaround the âelementâ to ensure âreliable ignition.
- no visible glow during a heat â¤cycle – check for open circuit or missing supply voltage.
- Intermittent â˘heat or long ignition delays – â˘inspect for hairline cracks or degraded âŁemissivity.
- Tripped safetyâ cutouts or blownâ fuses âwhen ignitor energizes – look for shorted element or wiring faults.
- Ensureâ replacement matches connector,flange orientation,and electrical specs from âthe service⣠manual.

How the 137524000 âŁFrigidaire Washer Dryer Ignitorâ Operates Within the Appliance: Ignition Sequence, Electrical âCharacteristicsand Control Signals
The 137524000 Frigidaire âWasher â˘Dryer Ignitor serves as the hot surfaceâ element that initiates combustion in â˘the dryer’s burner assembly. During aâ normal ignition âsequence the appliance control orâ timer applies mains voltageâ to the ignitor; the element heats to a glowing temperature and the control monitors the resulting rise in temperature (or a flame sensor) before energizing the âgas valve. Once âthe â¤valve opens and the burner â¤lights, the control typicallyâ removesâ or reduces powerâ to the ignitor because theâ sustained⤠flame will maintain combustion. âProper replacement requires⣠matching the ignitor’s electricalâ rating, connector âtypeand mounting so the⣠control’sâ timing⣠and safety interlocks (door switch, high-limit thermostat, flame sensor) operate as designed; substituting âa physically different element canâ cause delayed ignition, â¤false safety trips, â˘or control errors âeven if âit fits mechanically.
Electrically, theâ ignitor is driven by a timed mains-level⣠signal from âthe control board and is âdesigned to exhibit low impedance while warming and then stabilize when hot; technicians commonly verify element integrity withâ a continuity check and⣠verify operation with a voltmeter âand clamp ammeter during the ignition cycle. Practical diagnostics include confirming the control applies voltage to⤠the ignitor during the call for heat, measuring⢠theâ element’s âcurrent draw during warm-upand observing whether the control allows the expectedâ warm-up âŁinterval before⣠opening the gas valve. Typical failure⤠modes are open-filamentâ (no glow), slow-to-heat (element partially degraded)or âshorted/leaking insulation (nuisance tripping or burnt â¤connectors). For fieldâ troubleshooting, test continuity âat the âŁignitor leads, confirm presence of line voltage during the ignition⢠intervaland check associated safety sensors â¤before replacing⢠the part to ensure the problemâ is isolated to the ignitor itself.
- Common symptoms: no glow at ignition, gas present but no âlight, delayed ignitionor⤠repeated re-tries by theâ control.
- Field tests:⣠continuity across ignitor, voltage applied âŁduring the ignitionâ cycleand current draw duringâ warm-up.
- Replacement notes: match âpart number, connector styleand mounting to preserve control timing âŁand safety interactions.
| Item | Description |
|---|---|
| Voltage | Operates from âthe appliance’s⤠line supplyâ (commonly 120 VAC) and is switched byâ the control during âa call â˘for heat. |
| Warm-up time | Element reaches ignition temperature â˘within a few seconds; controls typically permit a⣠short timed â˘interval â¤(often âŁ1-8 seconds) before energizing⤠the gas valve. |
| diagnostic checks | Continuity, â˘presence of applied voltage during the ignition cycleand âmeasurement of currentâ draw and flame-sensing feedback. |
| Compatibility | Direct replacement⢠required to match electrical⣠characteristics,⣠connectorand mounting to ensure correct interaction âŁwith the control and safety devices. |
Common Failure â¤Symptoms âand Diagnostic Indicators ofâ ignitor Degradation âor Fault
The most common operational signs of a failing 137524000 Frigidaire Washer Dryer Ignitor are loss âŁof sustained flame, extended heat cycles,â or intermittent heating⤠that coincides with a visible⤠or inconsistent glow â¤from the ignitor element. Mechanically, a degraded ignitor will either fail to reach the â˘required âtemperature to open the gas valve â¤or will crack/break and lose âŁcontinuity; electrically this shows as open circuit or unusually high resistance. Compatibility issues – wrong connector,â incorrect mounting âbracketor different resistance characteristics – â¤can allow the assembly to fitâ but not perform correctly,⣠so⢠match theâ replacement part number and mounting â˘orientation to the applianceâ model âduring service. Practical examples include a dryer that tumbles normally but never heatsor a unit that heats briefly then shuts off as the ignitorâ cools and the control fails to detect a sustained flame signal.
- Visible signs: hairline fractures, white-hot spots that no longer âglow uniformlyor discoloration on the ceramic supports.
- Electrical signs: open circuit on continuity test or resistance âfar outside the ignitor’s expected range.
- Operational âŁsigns: long ignitionâ delay,repeated⢠ignition attempts,or no gas valve actuation despite control calling for heat.
Technicians should use a multimeter â¤and a non-contact voltage tester to confirm diagnostics: start⤠with â¤a continuity check âŁwith power removed, âŁthen measure cold resistance; â¤a healthy ignitor typically âshows a low-ohm resistance characteristic (vendorâ specs vary – often in the low tens toâ low hundredsâ of ohms). During a â˘powered ignition attempt measure for the presence of control⣠voltage âatâ the⤠ignitor terminals (usually near â120 VAC âin many gas dryer controls) to verify the control âis supplying power; absence â¤of voltage indicates a control, thermostat,â or safetyâ interlock fault rather thanâ the ignitor itself. When replacing, compare âconnectorâ type, mounting flangeand resistance values to the original; always de-energizeâ the appliance and shutâ off gas before performing⣠removal or âlive-voltage tests.
| Item | Description |
|---|---|
| Typical cold resistance | Generally low-ohm range (frequently enough âŁ~10-100â Ί); consult model-specific specs. |
| Expected â˘continuity | Closed circuit on a cold continuity test; âopen indicates a failed element. |
| Live test voltage | Control applies⣠line-level âvoltage during ignition sequence (verify ~120 VAC for many models). |
| Visual indicators | Cracks, brittleâ support insulatorsor uneven glow pattern suggest imminent failure. |
Compatibility, Replacement Considerations, Stepwise Installationand â¤Troubleshooting Procedures
The 137524000 Frigidaire⣠Washer Dryer Ignitor is a hot-surface ignition â¤element⢠designed toâ produce theâ thermal âŁenergy necessary to light the gas stream in âcompatible Frigidaire dryer and washer-dryer âcomboâ models.â The component functions by converting applied â¤electrical âpower into heat at a ceramic or silicon-carbide element;â when energized it should glow â˘visibly and reliably long â¤enough to igniteâ gas delivered by the valve. â˘Replacement considerations center onâ mechanical fit, connector typeand electrical characteristics-matching the OEM part number â˘ensures identical mounting tabs, lead lengthand expected operating current. Substituting a⢠physically similar ignitor without confirmingâ voltage rating or connector âŁpolarity can yield poor contact, premature failureor intermittent ignition behavior, so crossâreference the appliance model and verify dimensions and⢠terminal type before installing a nonâOEM unit.
Disconnect power â˘and gas supply before any work. Typical stepwise replacementâ begins with removing the access panel, documenting wire locations orâ taking a⤠photoand testing the removed ignitor for continuity with a âmultimeter; an open circuitâ usually indicates failure. Install the new ignitor by securing mounting screws to the original torque points, reconnecting the harness âŁwith correct polarityand âavoiding contact with theâ ceramic surface to prevent contamination or mechanical damage. For troubleshooting: if âthe⤠ignitor glows but no flame âŁappears, measure the gas valve coil voltage and check the flame sensor/thermocouple â¤path; âif the ignitor does not glow, verify continuity,â check thermal cutoff âŁfuses and control board output for the ignition cycle. Common âswift âchecks are⣠listed below to help isolate the fault efficiently.
- no glow andâ no ignition: âtest ignitor continuity, supply voltage from â˘the control boardand upstream fuses/thermal cutouts.
- Ignitor glows but no flame: measure gas valve coil voltage and âŁinspect the flame sensor⤠and gas supply âpath for â˘blockagesâ or failed valves.
- Intermittent ignition: â¤inspect connector integrity, mounting alignmentand control âboard relay/cycle timing for â˘erratic⤠behavior.

Q&A
What is the 137524000 Frigidaire washerâdryer ignitorâ and what does it do?
The 137524000 is the glow ignitor⢠(also called a â˘surface ignitor or glow bar) used on Frigidaire gas dryer/builder units.When the âŁdryer âŁcalls for heat,⤠the control sends power toâ the ignitor so it glows â¤redâhot; once it reaches âignition temperature the gas valve opens and the gas is ignited âby the hot âsurface. It is indeed â˘not â˘used in electricâresistive dryers – those use a⤠heating element rather.
What â˘are the common symptoms that the ignitor (137524000) has failed?
Typicalâ signs of a bad ignitor include: the dryer âtumbles⣠but produces noâ heat; you hear repeated⤠clicking without âŁflame; â˘the ignitor does not âglow; or the dryer takes a longâ time to light. Visual signsâ include a crackedâ or broken ceramic/glass âbody or a visibly brokenâ filament. Note that other faults (thermal fuse, gas valve⣠coils, blocked vent, controlâ board) âcan cause similar symptoms, âso further testing is often needed.
How can I test the 137524000 ignitorâ to see if it is bad?
First, disconnect electrical powerâ and shutâ off âthe gas. Access⢠the ignitor per your model’s serviceâ instructions. Doâ a visual inspection for cracks orâ breaks. âUse âaâ multimeter set to continuity/ohms to check the ignitor: an open circuit (infinite resistance) indicates âa failed⤠ignitor. A healthy ignitor⤠normally shows âlow resistance (consult the part/spec⣠sheet for the exact range). If you are competent and qualified, you can also check for ignition âvoltage at the connector whileâ operating⣠(with gas off), but live⢠electrical testing on gas appliances presents hazards – consider â˘a trained technician if unsure.
How do I replace âŁthe⤠137524000 ignitor âsafely?
highâlevel âreplacement steps: 1) Disconnect electrical power and shut offâ the gas supply.â 2) â˘Remove âŁthe dryerâ access âpanel(s) to reach the âŁburner box.3) âUnplug the âignitor connector and remove⣠the⣠mounting screws – handle the ânew âŁand old⤠ignitor carefully (the element and ceramic are fragile). 4) âInstall the new ignitor without touching the âŁhot surface/ceramic with bare fingers, secure wiring and fasteners, reassemble panels. 5) Restore power and gas, runâ a short âheat cycle and check for proper ignition and â¤for â˘gas leaks. â˘Because of âŁgas and electrical hazards, ifâ you’re not cozy âŁwith â¤these steps,â hire a qualified technician.
Isâ part⢠137524000 compatible with my Frigidaire model?
Compatibility depends on your specific model. Always verify using your dryer’s âfull model and serial â˘number, the part numberâ printed on the old ignitoror Frigidaire/authorized partsâ lookup. some ignitors are interchangeable acrossâ several models, but do not assume fitment without confirmation. OEMâ parts lists âor authorized dealers can confirm compatibility.
After replacing the ignitor, my dryer still âwon’t heat – what else should I check?
If a âknown âŁgood ignitor is⣠installed âbut there’s still no⣠flame, check the following: âŁgas supplyâ to â˘the⤠dryer, gas⢠valve coils, thermal cutoff/limit thermostat, fuse âor â¤highâlimitâ thermostat, flame sensor (if equipped), venting/airflow restrictionsand control boardâ or⤠wiring faults. â¤A multimeter continuity check of⤠the thermal fuse and gas⣠valve coil resistance tests can definitely âhelp isolate the fault. If you’re âunsure, get âa⤠qualified appliance technician to perform a systematic diagnosis.
Can I install the 137524000 ignitor myself or should I hire a technician?
You can replace the ignitor yourself⤠if â˘you are comfortableâ with basic appliance disassembly andâ follow âŁsafety steps: disconnect âpower⢠and gas,⤠use proper toolsand handle theâ part carefully. Though,as⢠this is a gas appliance,there are critically important safety risks (gas leaks,fire) â˘andâ local codesâ sometimes require a licensed technician forâ gas work. If you lack experience with gas appliance service, hire a qualified technician to ensure safe installation and testing.
