137524000 Frigidaire âwasher Dryer Ignitor is⢠an ignitor assembly used in Frigidaire âŁgas âdryer⤠and combination washer-dryer appliances to provide the initial ignitionâ source for the burner.â the component⤠typically consists of a heating element and mounting bracket with connector terminals and is âdesigned⤠to reach combustion temperature rapidly when energized; in many models this function is implemented as a hot-surface (glow) ignitor, although ignition â˘technology can vary by model. As a field-replaceable part, it is identifiedâ by its OEM part number and physical interface âto âŁthe appliance’s burner housing.
Inside the appliance âthe ignitorâ is part of the gas ignition subsystemâ and directly interacts with the control board,gas â˘valve coils,flame sensing orâ thermal cutoff devices,and the burner assembly. When the dryer calls for heat the control board⢠supplies voltage to⤠the ignitor so it heats to the required temperature; onc the ignitor is hot the gas⣠valveâ is opened and the flame sensor⤠confirms sustained combustion. Proper operation depends⣠on correct electrical supply,intact â˘sensing circuits,and correct positioning â˘relative to⢠the â˘gas orifice andâ burner ports,so failures or âŁmisalignment can prevent ignition or create unsafe conditions such as delayed⣠lighting or gas pooling.
This article explains the ignitor’s â˘function and typical design, describes⤠model compatibility and common cross-references for the 137524000 unitand outlinesâ typical failureâ symptoms⤠technicians and âappliance owners should recognize (for â˘example, no heat, intermittent heating, âvisible cracksor failed continuity checks). It also covers diagnostic stepsâ to⣠isolate âignitor faults from gas â˘valve⢠or control-board issues, safety considerations for testingâ and replacementand practical⢠replacement considerations such as connector type, mounting orientationand verifying proper operation after installation.

Functional role and Electrical/Thermal Requirements ofâ the Dryer ignitor assembly
The 137524000 Frigidaireâ Washer âDryer Ignitor is a glowâbar style ignition⤠element that provides the initial thermal stimulus required to operate the gas valve and initiate combustion in compatible Frigidaire dryer âassemblies. When the control board or thermostat calls for heat, the ignitor is supplied with line voltageâ and must âreach âits operating temperature quickly and consistently;â once âit reaches the required temperature the gas valve opens and the burner lights. âŁfunctionally, the ignitor âis not âŁa continuous heater but a timed, âhighâresistance element integrated withâ the mounting â˘bracket and connector that must⤠match the âappliance harness⢠and control signals to ensure correct â˘sequencing and safety interlocks.
Electrical and thermalâ behavior determine compatibilityâ and âdiagnostic strategy: the ignitor is designed for short, repetitive⤠energization from the dryer control⣠circuit and must tolerate âthermal â˘cycling âand vibration. âŁTechnicians typically verify â¤operation by checking cold continuity, observing warmâup time and visible glow under controlled, deâenergized inspection conditionsand confirming â¤that related safetyâ devices (thermal fuses,â thermostats) and the control board supply theâ correct drive. Forâ installation,confirm connector type,mounting âposition and⢠that the⢠replacement ignitor operates at the same nominal line âvoltage and âtiming characteristics as the original; for safety and reliable operation have mainsâlevelâ testing and live checks â˘performed byâ qualified personnel.
- Common failure âsymptoms: no heat, delayed ignition, â˘repeated âcycling,â visible element crackingor an⤠open circuit reading on a multimeter.
| Item | Description |
|---|---|
| Ratedâ system voltage | Typically driven by the appliance’s lineâ control âvoltageâ (verify model service literature for exact âvalue). |
| Warmâup behavior | Designed âto reach operating temperature within aâ few seconds âŁof beingâ energized⢠to allow âthe gas valve to âopen. |
| Cold âresistance | Low resistance when cold⢠(single to low âŁtens âof ohms is common); measure with a multimeter and compare â¤to service spec. |
| Failure⢠modes | Open filament,â cracked or broken element,⣠degraded heat⢠output from repeated cyclingor âconnector/mountingâ incompatibility. |
| recommended â¤test | Isolate power, check continuity and resistance, âthen verify⤠warmâupâ and âvisible glow only with appropriate safety precautions or by a qualified âtechnician. |
How the 137524000⤠Frigidaireâ Washerâ Dryer Ignitor Operates Within Frigidaire Dryer Gas and Control Circuits
The â¤137524000 Frigidaire Washer Dryer Ignitor is⢠a resistive glow-element that â¤interfaces directly with the⤠dryer’s gas and control circuits to initiateâ combustion. When a heating cycle is requested,the dryer control applies mainsâ power to the ignitor through the series safety path⣠(fuses/thermal cutouts,high-limit thermostat,and any interlocks). The ignitor heats to a visible glow âand the control then⣠opens the gas valve âfor a⢠briefâ timed interval; â¤a dedicated âflame-sensing circuit or switch confirms a successful ignition and holds âthe gas valve energized. Proper operation depends⢠on correct electrical connection, the ignitor’s mechanical mounting and clearance⢠relative to the burner tubeand the timing signals from âthe control module – mismatched replacement parts âŁor connector changes⢠canâ interrupt this sequence and⤠prevent âreliable âŁignition.
- Common symptoms of ignitor-related âŁfaults:⢠no heat, delayed âignition, intermittent âflameor visible⣠cracking/chipping ofâ the glow element.
- Field checks typically include⤠a visual inspectionâ for physical damage, a continuity test âwith a multimeterand verification that 120 â¤VAC is present at the ignitor terminals during the preheat interval.
- Disconnect power and gas before performing any hands-on diagnostics or replacement to avoid electricalâ shock or gas âhazard.
Troubleshooting⤠should consider⣠both the ignitor and the surrounding â˘safety and sensing components: a good ignitor can still fail to light the burner if a thermal cutoff or âflame sensorâ is open,â or if the control never supplies voltage. In practical terms, âtechnicians confirm the control is commanding the ignitor (measure voltage during a callâ for heat), verify â¤continuity of seriesâ safety devicesand inspect⣠wiring harnesses and connector pins for âŁcorrosion⢠or looseness. Replacing the ignitor with an OEM-matched unit like the 137524000 Frigidaire Washer Dryer Ignitor preserves the original mounting and electrical interfaces; after replacement, confirm correct ignition timing and⣠that flame sensing holds the gas valve during steady-state⢠operation.

Commonâ Failure Modes, Observable symptomsand Initial âDiagnostic Checks
The⣠137524000 Frigidaire âWasher âdryerâ Ignitor is a glow-bar style heating â¤element usedâ on âŁcompatible Frigidaire gas dryer⤠units⤠to provide the initial thermal source for gas â¤ignition. Typical âfailure modes include an âopen filament (no continuity), â¤hairline fractures or â¤pitting⢠in âthe ceramic/glass âelement that reduce emission and slow heat-upand intermittent connection failures at the harness or â˘mounting tabs. Compatibility is âŁlimited to specific â¤Frigidaire⢠models and⤠harness types,⤠so confirm the appliance model and connector âarrangement before replacement;⤠a common â¤symptom that points to the âignitor is a dryer that tumbles normally but produces â˘no heat or shows âa long ignition delay at âthe start of the cycle, whereas repeated thermal fuse failures can indicate a weak or slow-heating ignitor that allows âsustained heat buildup.
- No heat âwhile motor âruns â-â check ignitor continuity and visual condition for cracks or discoloration.
- long ignition delay or clicking relaysâ – â˘measure cold resistance (expect low ohms) and monitor voltage at the ignitorâ harness âduring the start⢠sequence.
- Intermittent heating – inspect wiring, connector corrosionand mounting strain on the ignitor element.
- Gas odor âwithout â¤ignition – verify âignitor âfunction first, thenâ check gas⢠valve coils and â¤flame sensor if ignitor tests good.
- Initial safety checks – disconnect power and gas, perform⢠a visual inspection, then use a multimeter⤠to test continuity and resistance before powering the unit for⣠live-voltage â¤checks.
| Item | Description |
|---|---|
| Typical cold resistance | Single-digit to lowâtens â¤of ohms; an open circuit⢠indicatesâ a failed element (verify exact⣠spec in service manual) |
| Observableâ failure modes | Open filament,surface cracking,connector corrosion,slow heat-up⢠due to increased resistance |
For an effective â¤initial diagnosis,follow a âshort workflow:⢠perform a⤠visualâ inspectionâ for physical damage,verifyâ continuity âand approximate âŁcold âresistance with a digital⤠multimeter,then observe the ignitor under power âwhile monitoring for correct appliedâ voltage during the start cycle (refer to the dryer’s wiring diagram for expected values). If the ignitor reads continuous but does not glow when voltage is present, the problem is likely in the â˘control circuit, relayor wiring rather than the ignitor itself; conversely, an âopenâ or high-resistance reading on the ignitor justifies â¤replacement. also âcheck ârelated safety⢠components â˘- thermal fuses, high-limit thermostatsand the flame sensor – becauseâ thay ofen produce the same symptoms âas a failedâ ignitor âŁand should âbe ruled out âŁbefore concluding compatibility or ordering a replacement.
Model Compatibility, Replacement Criteria, Installation Proceduresand Advanced Troubleshooting
The 137524000 Frigidaire âWasher Dryer Ignitor âfunctions as the hotâsurface element that reaches ignition temperature to light the⢠burner when the control boardâ calls for heat. Compatibility is steadfastâ by âphysical mounting points, â¤the twoâpin harness style and orientationand the OEM reference number â¤rather than by generic measurements alone; match the ignitor to the applianceâ model⣠and connector type before ordering. In operation âthe ignitor presents a measurable resistance when⤠cold and draws⢠current only during the heat cycle; typical failure modes are filament open circuit, thermal cracking of the ceramic substrateor degradation from lint and moisture that reduces⣠element life and causes intermittent âheating behavior.
Replace â˘the ignitor ifâ you measure an âŁopen circuit, see visible fractureorâ observe no glow despite correct control signals;â replacement requires shutting⢠off electrical power and gas,⤠removing the burner access paneland installing⣠the matched part with existing mountingâ screws and proper connector alignment. Advanced troubleshooting steps â¤include verifyingâ that 120âŻVAC (or the appliance’s rated supply) is present at the ignitor connector during a heat â¤call, confirming continuityâ of highâlimit thermostats and safety⣠interlocksand isolatingâ the gas valve coils -â an ignitor that shows continuity but does not â˘glow while⢠receiving âŁtheâ correct voltage indicatesâ a control âor wiringâ fault rather than a failed element. Recordâ resistance⣠and voltage readings during diagnostics âand restore proper lint clearance⤠and airflow after service to reduce the⢠risk of premature failure.
- Diagnostic checks: continuityâ (open = replace), visual inspection⤠for cracksand voltage present duringâ heat call.
- Compatibility checks: match OEM number, mounting tab⢠orientationand connector style.
- Installation notes: disconnect power and gas, handle the element by the mounting bracket âŁto avoid thermal shockand tighten mounting hardware to specified torque.
- Common symptoms: no heat, long dry times, intermittent heatingor visible sparking at the ignitor.
| Item | Description |
|---|---|

| Connector | Twoâpin harness orientation and âŁterminalâ type determine electricalâ compatibility; adapters may be requiredâ ifâ connectors differ. |
| Diagnostic test | Measure cold resistance (measurable âŁbut low);⣠open circuit indicates failed element. âŁVerify voltage during âaâ heat call to distinguish control faults. |
Q&A
What is the 137524000 Frigidaire ignitorâ andâ whichâ machines does â˘it fit?
The 137524000 âisâ an âOEM glowâbar (igniter) assembly usedâ in Frigidaire gasâ dryer models (and some stackable washerâdryer combinations that use a gas dryer section). It is a gasâdryer⢠component only (not used in electric dryers). Always confirm fit by â¤matching the part numberâ to your dryer model number or by âcrossâreferencing in the appliance parts lookup for your exact model.
What symptoms indicate the ignitor is failing?
Common signs of â˘a bad ignitor include: the dryer tumbles but produces no heat, prolonged or repeated heating cycles, the ignitor â˘does not glow when âŁa heat cycle startsor the dryer âŁclicks repeatedly âŁwithout igniting. Visible cracks or breaks in the ceramic/glass elementâ are also a clear sign it’s failed.
Howâ can⣠I test the ignitor to see â˘if it’s bad?
First âdo a visual â¤inspection for cracks or burn damage. With theâ dryer⣠unplugged, useâ a multimeter âŁto checkâ for continuity across the ignitor – itâ should show continuity and a relatively⣠low resistanceâ (typically â¤tens to âa few hundred ohms); an open circuit (infinite resistance) indicatesâ failure. A qualified technician canâ also verify that the ignitor⤠receives the proper voltage during the start⣠of a⢠heat cycle,â but â¤live â˘testing involves â¤electrical and gas hazards and should be done cautiously.
Can I replace⢠the 137524000 ignitor âmyselfand what âsafety⣠steps should I follow?
Yes, a competent â¤DIYer can replace it, but follow⣠strict safety⢠steps: unplug the dryer’s electricalâ power⤠and shut offâ the gas supply, allow â˘componentsâ to cool,â wear⣠gloves,â and avoid touching the ignitorâ element surface (oils from skin can shorten its life).
