137524000 Frigidaire Washer Dryer Ignitor is an electrical glow ignitor assembly used in Frigidaire gas dryer and washer‑dryer combination units. It is a replaceable heating element (commonly called a glow bar or igniter) that converts electrical energy into heat rapidly enough to ignite the dryer’s burner gas when called for by the control system. The component is typically a fragile, high‑resistance element mounted in the burner tube or burner housing and supplied as a discrete service part for model‑specific applications.
Inside the appliance the ignitor’s role is to reach ignition temperature and thereby allow the gas valve to open and sustain combustion; it therefore interfaces directly with the control board or timer, low‑voltage relay circuitry, and the gas valve coils, and it is protected by safety devices such as thermal fuses, high‑limit thermostats and flame sensors. Proper operation depends not only on the ignitor element itself but also on the continuity of wiring, functioning of upstream safety thermostats, correct control signals, and adequate airflow and venting; a fault in any of these systems can produce the same symptom as an ignitor failure.
This article explains the ignitor’s electrical and mechanical function, how to verify model compatibility for replacements, common failure symptoms to recognize (for example no‑heat conditions, ignitor not glowing, or rapid cycling), and systematic troubleshooting steps a technician or owner can use to isolate the fault. It also covers practical replacement considerations – part matching, handling and mounting the fragile element, and checks to perform after installation – while highlighting the safety and diagnostic checks that should accompany any service on gas‑fired appliances.

Function and Role of the Ignitor in Dryer Heat Generation and Safety Circuits
The 137524000 Frigidaire Washer Dryer Ignitor is a replaceable hot-surface component that provides the initial thermal energy required to ignite gas in compatible Frigidaire dryer models. When energized by the dryer control, the ignitor heats to an incandescent temperature and preheats the incoming gas so the main gas valve can open and sustain combustion; it does not produce a spark. Proper compatibility requires matching the mounting bracket, terminal type, and electrical characteristics so the control board and safety thermostats operate as designed-incorrect replacements can prevent ignition or create nuisance trips of high-limit or flame-sensing circuits.
Operationally, the ignitor is integrated into a sequence: the control supplies voltage to the ignitor, the ignitor reaches sufficient temperature, the gas valve opens, and a flame-sensing device confirms ignition before the ignitor is de-energized. The ignitor also interacts with safety circuits such as the high-limit thermostat and flame sensor/thermocouple; if these circuits detect overtemperature or absent flame, they interrupt power to the valve and ignitor to prevent gas flow without combustion. Technicians verify functionality with a visual check for a steady glow during a heat call and with a continuity or resistance measurement; common diagnostics include a visible non-glowing element, an open circuit reading, or cycling that indicates an intermittent connection or control fault.
- Symptoms of failure: dryer runs but no heat, ignitor does not glow, or intermittent ignition.

How the 137524000 Frigidaire Washer Dryer Ignitor Operates within the Burner Assembly and Control Loop
The 137524000 Frigidaire washer Dryer Ignitor serves as the primary ignition element in the gas burner assembly and is electrically integrated into the dryer’s control loop that sequences heat delivery. When the control board calls for heat, it supplies voltage to the ignitor so the element rapidly reaches an incandescent temperature; after a brief warm-up the gas valve is energized and gas flows across the glowing element where combustion is initiated. The control loop then relies on a flame-sensing circuit-typically flame rectification using a flame rod or a thermocouple input-to confirm stable combustion before maintaining the gas valve open. Mechanically and electrically, the ignitor must match the original in mounting tabs, connector type, and electrical characteristics so that timing, current draw, and thermal rise align with the dryer’s safety interlocks and software timing routines.
- Normal behaviour: quick glow followed by sustained flame confirmation via the sensor.
- Failure symptoms: no glow (open circuit), slow or dim glow (high resistance or weak supply), or ignition without sustained flame (sensor or gas valve issue).
- Compatibility factors: connector pinout, mounting orientation, and rated voltage/current must match the OEM part.
- diagnostic steps: verify supply voltage at the ignitor connector, measure cold resistance for continuity, observe glow time, and confirm flame-sensor feedback to the control board.
For practical troubleshooting, technicians should distinguish ignitor faults from downstream components: an ignitor that does not glow under correct control voltage is a direct replacement candidate, while an ignitor that glows but fails to produce a sustained flame points to gas flow, gas valve coil, or flame-sensor faults. Bench testing with a multimeter for continuity and an inline voltage check during a heat cycle will clarify whether the control board is commanding the ignitor and whether the element draws the expected current; if the control loop does not detect flame within the programmed time window it will drop the gas valve and lock out further attempts until the cycle resets. Replacing the ignitor with the specified 137524000 part ensures compatibility with the dryer’s timing and sensing thresholds and reduces the risk of repeated control-loop timeouts or unsafe conditions.

Common Failure Symptoms and Diagnostic Tests for Ignitor Degradation
The 137524000 Frigidaire Washer Dryer ignitor is the resistive glow element used to initiate the gas burner in compatible Frigidaire washer‑dryer combo units. Its primary function is to reach incandescent temperature quickly so the gas valve can open and the burner will light; as the filament ages it may take longer to glow, develop cracks or carbon deposits, or change resistance characteristics that prevent reliable ignition. This ignitor must match the appliance’s mounting,harness connector and thermal-sensing arrangement – a physically or electrically different ignitor can fail to seat correctly or present an unexpected resistance to the control circuit,producing false diagnostics unless compatibility is confirmed before replacement.
- No heat or intermittent heating while the drum and motor run.
- Extended ignition delay or frequent repeated ignition attempts without sustained flame.
- Audible clicking as the control cycles the ignitor/valve but no burner lights.
- Visible damage such as cracks, chipping, or heavy carbonization on the glow bar.
| Item | Description |
|---|---|
| Continuity / Resistance | Measure with power disconnected. A usable ignitor shows continuity (low resistance); an open circuit indicates a failed filament and requires replacement. |
| Resistance expectation | Typical cold resistance is in the range of tens to a few hundred ohms depending on design; substantially lower values suggest a partial short, substantially higher or infinite resistance indicates deterioration or break. |
| Voltage presence | When the dryer calls for heat the control should apply line voltage briefly to the ignitor; absence of the expected voltage points to control, thermostat, or safety cutout faults rather than the ignitor itself. |
| Visual / operational test | When energized safely, the element should glow visibly within seconds. No glow with correct supply voltage means the ignitor is failed. |
For diagnostics start with a visual inspection, then confirm continuity with a multimeter while the unit is de-energized; next, verify that the control actually supplies voltage to the ignitor during a heat call (only if you are qualified to perform live-voltage checks). If the ignitor reads open or shows intermittent continuity, replace it.If the ignitor measures correctly but there is no voltage at the terminals, troubleshoot upstream components such as thermostats, flame sensors, thermal cut-offs, or the control board. In practice, a common repair scenario is a dryer that clicks repeatedly and never lights-the ignitor frequently enough tests as open or shows visible damage, and replacing the ignitor restores reliable ignition; conversely, if the ignitor tests good but no flame occurs, the technician should focus on control and safety devices. Always isolate electrical power and gas supply before performing inspections or repairs and follow safe testing procedures when measuring live circuits.
Compatibility, Replacement Considerations and Installation Procedures for 137524000 and Equivalent Units
The 137524000 Frigidaire Washer Dryer Ignitor is a resistive hot-surface element used to initiate combustion in the dryer section of combination washer‑dryer units with gas heat. in normal operation the control board supplies voltage to the ignitor so it reaches a high temperature and emits visible glow; a downstream gas valve then opens and the burner ignites, with flame detection circuitry confirming combustion. Failure modes are typically an open or shorted element, cracked ceramic, or intermittent heating caused by corrosion at terminals; technicians confirm faults with both a visual glow test and a multimeter resistance/continuity check at the ignitor connector while also verifying that the control board supplies the expected drive voltage during a timed ignition cycle.
- Disconnect power and gas before replacing the ignitor; always verify zero voltage at the connector.
- Confirm mechanical fit: mounting bracket orientation,terminal type,and clearance from the burner tube must match the original unit.
- Measure cold resistance and compare to known-good values for the model, and verify that flame detection and gas valve operation are functional after replacement.
- When substituting equivalent parts, ensure the replacement matches the original’s connector, mounting holes, and thermal characteristics rather than only matching the part number.
Compatibility decisions should be based on physical and electrical parameters rather than catalog listings alone; equivalent units that share the same mounting geometry and connector may still differ in element composition or heat-up time, which can affect ignition timing and flame sensing. During installation, route and secure wiring away from heat and sharp edges, torque mounting fasteners to avoid stressing the ceramic, and perform a full ignition cycle test while monitoring for correct flame establishment and stable sensor feedback. If installation of a replacement ignitor does not restore reliable ignition, inspect adjacent components such as the flame sensor/thermocouple, gas valve coil resistance, vent restrictions, and the control board ignition circuitry before assuming the ignitor is at fault.

Q&A
What is the 137524000 Frigidaire ignitor and what does it do?
The 137524000 is a replacement hot surface/glo-bar ignitor used on Frigidaire gas dryer and washer-dryer combo units. Its job is to heat to a high temperature so the gas burners ignite when the gas valve opens. Without a working ignitor the burner will not light and the dryer will tumble without producing heat.
How do I know if my dryer uses part 137524000?
To confirm compatibility, check your appliance model number on the serial plate (typically on the door frame or back panel) and cross-reference it with the part number in the Frigidaire parts diagram or a trusted parts supplier. Many parts are used across multiple models, but always verify by model number rather than assuming fit by appearance alone.
What are the common symptoms of a failing or failed ignitor?
Common symptoms include no heat while the drum tumbles, repeated clicking without a flame, the dryer lighting briefly then shutting off, or an error code related to ignition on newer units. A cracked or visibly damaged ignitor or an ignitor that does not glow when the burner cycle begins are also clear signs of failure.
How can I test the ignitor to see if it is indeed bad?
Start with a visual inspection for cracks, breaks or burn damage. With the dryer unplugged and the ignitor disconnected, use a multimeter to check for continuity; a functioning ignitor normally shows continuity while a wholly open circuit indicates a broken filament. If it shows continuity but the ignitor doesn’t glow in operation, you should also verify that the control is sending voltage to the ignitor and that the safety thermals, flame sensor/thermocouple, and gas valve are functioning.
Can I replace the 137524000 ignitor myself, and what are the basic steps?
Yes, a mechanically inclined homeowner can replace it, but observe safety precautions. General steps: disconnect electrical power and shut off the gas supply; remove the dryer access panel(s) to reach the burner assembly; disconnect wiring and remove the old ignitor (handle the element carefully-do not touch the ceramic/glow surface with bare hands); install the new ignitor, reconnect wiring and panels; restore gas and power and run a test cycle while checking for proper ignition. If you are not comfortable working around gas or electrical connections, hire a qualified technician.
What tools and materials are needed for replacement?
Typical tools: screwdriver or nut-driver set (to remove panels and fasteners), a multimeter (for testing), needle-nose pliers, work gloves, and possibly a socket set. Also have a rag and mild cleaner to remove lint/debris around the burner area. Do not touch the ignitor element with bare hands-oil from skin can shorten its life.
How long does replacement usually take and how much does the part cost?
Replacement typically takes about 30-60 minutes for someone familiar with appliance repair. The part cost varies by supplier and whether it’s OEM or aftermarket-expect a range from roughly $20 to $80. Labor costs will increase the total if you hire a technician.
What safety checks should I perform after installing a new ignitor?
After installation, restore gas and electrical power and run a short heat cycle while observing ignition. Check that the ignitor glows and the burner lights reliably. Inspect for gas leaks around fittings and the gas shut-off-if you smell gas or detect a leak, shut off the gas instantly and call a professional. Also verify the dryer vent is clear and that any flame sensors or thermostats are operating normally.
Key Takeaways
The 137524000 Frigidaire Washer Dryer Ignitor serves a critical role in gas dryer operation by producing the heat necessary to ignite the burner assembly, enabling reliable and efficient drying cycles. as an integral component of the appliance’s ignition system,a functional ignitor helps ensure consistent performance,energy efficiency,and safe operation; a failing or degraded ignitor can lead to no-heat conditions,prolonged cycles,or repeated ignition attempts that may stress other components.
Because symptoms of ignition issues can arise from several parts within the gas and control systems, proper diagnosis is essential before replacement. Confirming the ignitor’s condition with appropriate testing methods or a qualified technician and using the correct replacement part helps restore normal operation,maintain safety standards,and avoid unnecessary expense. Timely, accurate diagnosis and installation of the proper 137524000 ignitor support the longevity and dependable performance of Frigidaire washer-dryer units.
