137524000 Frigidaire Washer Dryer Ignitor is a hot-surface ignitor used as the ignition element in gas-heating sections of Frigidaire gas dryers and combination washer-dryer appliances. It is a ceramic resistive element mounted in the burner assembly that, when electrically energized, glows hot enough to ignite the gas supplied to the burner.as a discrete replaceable component it is identified by its part number and specific mounting and connector configuration for compatibility with certain appliance models.
Inside the appliance the ignitor is a key element of the ignition sequence and interacts directly with the control board, gas valve coils, flame sensing circuit, and thermal safety devices. During a typical start cycle the control board supplies power to the ignitor so it reaches ignition temperature, then opens the gas valve; flame presence is then confirmed by the flame sensor or other feedback before normal heating continues. The ignitor is installed in the burner tube or burner housing adjacent to the gas ports and is subject to mechanical, thermal and electrical stresses, making its condition relevant to both heating performance and combustion safety.
In this article readers will find a technical description of the ignitor’s function, guidance on model and connector compatibility, common failure symptoms and how they present in the appliance, systematic troubleshooting steps (visual inspection, continuity/resistance checks and voltage verification during the ignition cycle), and practical replacement considerations including safety precautions and proper handling of the element. The focus is on providing technicians, engineers and appliance owners with clear, actionable details for diagnosing and replacing the ignitor while observing standard electrical and gas-safety procedures.

Function and Role of the Dryer Ignitor in Frigidaire Washer‑Dryer Gas Heating Systems
The 137524000 Frigidaire Washer Dryer Ignitor functions as the hot-surface ignition element in the appliance’s gas heating subsystem, providing the controlled thermal energy required to actuate the gas valve and ignite the burner. As a resistive ceramic element, the hot-surface ignitor must reach a specific temperature within the control’s timing window; the control board applies voltage to the ignitor, waits for the correct rise in temperature or a proper flame-sense signal, then energizes the gas valve. Typical failure modes are open-circuit resistance, hairline fractures in the ceramic that prevent uniform heating, slow ramp-up due to internal degradation, or contamination/glazing that reduces radiant output and prevents reliable ignition.
- symptoms of failure: no heat while drum turns, ignitor not glowing, or repeated ignition cycles without flame establishment.
- Electrical behavior: a functioning element shows low but finite cold resistance and draws current to heat; an open reading indicates replacement.
- Mechanical compatibility: correct mounting, connector type, and alignment with the burner or flame sensor are required for reliable operation.
- Maintenance note: inspect associated gas valve coils and flame sensor if ignition timing or flame detection was abnormal before replacement.
| Item | Description |
|---|---|
| Typical cold resistance | Low ohms (varies by design) – continuity expected; open = failed |
| operating supply | Control-voltage pulse from main board (verify model-specific rating) |
| Common replacement check | Visual glow under controlled test and multimeter continuity; verify connector and bracket fit |
Compatibility depends on matching the ignitor’s electrical characteristics and mounting geometry to the washer‑dryer model; even elements that glow but have different resistance or misaligned mounting can lead to poor ignition or false flame-fail faults.In field practice,technicians confirm a suspected bad ignitor by measuring continuity,observing the element under controlled energization for proper glow time,and verifying that the control sequence completes (ignitor warm-up followed by gas valve actuation).Replacing the ignitor with a part that matches connector type, bracket position, and thermal response typically resolves heating failures, but persistent problems warrant inspection of wiring, control outputs, and the gas valve assembly.
How the 137524000 Frigidaire Washer Dryer Ignitor Operates within the Gas Valve and Ignition Circuit
The 137524000 Frigidaire Washer Dryer Ignitor is a resistive glow element used in gas-fired washer-dryer combinations to provide the pilot heat required for the gas valve to admit fuel. In typical operation the control board or timer applies line voltage to the ignitor, the element heats and reaches visible orange glow, and then the gas valve coils are energized to open and release gas. The ignition circuit is interlocked with safety components-thermal cutouts,high-limit thermostats,and door or pressure switches-so the ignitor will only receive voltage when those sensors report safe conditions. In practice, technicians confirm ignitor function by measuring continuity and observing the glow interval; a cold open circuit or a physically cracked element indicates replacement is required rather than valve adjustment.
- Resistive preheat: element glows to raise temperature for reliable ignition.
- Sequence-controlled: ignitor receives power only after safety/pressure switches close.
- Common failures: open filament, surface cracks, or slow warm-up causing repeated ignition attempts.
- Compatibility: designed for glow-type gas valves; not compatible with spark or direct-flame systems.
| Item | Description |
|---|---|
| Function | Resistive glow ignitor that preheats combustion pathway so the gas valve can open and establish flame. |
| Operating voltage | Line voltage (typically 120 VAC in North American models) supplied through the control circuit. |
| Compatibility | Used with Frigidaire glow-ignition gas valves and associated safety switches; not suitable for spark-ignition systems. |
For troubleshooting,measure the ignitor’s cold resistance and check for continuity; a healthy element will show a low-ohm resistive path rather than an open circuit,and it should visibly glow when energized during a test cycle. If the ignitor glows but the valve never opens, investigate the gas valve coils and the sequencing signals from the control board or safety interlocks rather than replacing the ignitor alone. When replacing the part, ensure mounting orientation and connector type match the original, and always isolate power and gas before any service to avoid injury or equipment damage.
Common Failure Symptoms, electrical Measurements, and Failure modes of the Ignitor Assembly
The 137524000 Frigidaire Washer Dryer Ignitor is a resistive glow-type element used to initiate combustion in compatible Frigidaire gas washer-dryer units and retrofit applications that share the same mounting and terminal configuration.It functions by converting electrical energy to heat; when the control applies line voltage the ignitor element quickly heats to red‑hot, allowing the gas valve to open and the burner to light. Compatibility depends on physical fit (bracket and terminal type), the ignitor’s cold-resistance range, and the appliance’s control strategy, so confirm those characteristics against the service sheet before replacing the component.
Technicians commonly diagnose ignitor faults with simple electrical checks and observation of system behavior. Typical failure symptoms include no glow, intermittent glow, delayed ignition, or a breaker tripping when the circuit is energized. Practical electrical checks are: continuity (open circuit indicates a broken filament), cold resistance measured with a multimeter (an unusually high or infinite reading suggests degradation), and verification of supply voltage at the ignitor connector during a start cycle (the element normally sees line-level voltage for a short interval).Physical damage such as cracked ceramic, corrosion at terminals, or short-to-chassis faults are common failure modes that will require replacement of the ignitor rather than repair.
- No glow at start – often shows open circuit or very high resistance on an ohmmeter.
- Intermittent glow or weak glow – may read higher-than-normal resistance or have hairline cracks in the element.
- Glow present but no ignition - check gas valve coils and venting; ignitor may still be marginal despite appearing to glow.
- Short to ground or shorted terminals - can blow fuses or trip breakers and requires replacement.
| Item | Description |
|---|---|
| Cold resistance | Measured with multimeter; typical ranges vary by model. Expect a low‑ohm resistive element (consult service manual), and treat very high or infinite readings as a failed ignitor. |
| Supply voltage | The ignitor is generally driven by line voltage during the ignition interval (roughly 110-130 VAC on North American equipment); verify voltage at the connector during a timed start cycle. |
| Continuity | No continuity = open filament. Continuity plus very high resistance indicates marginal life and unpredictable operation. |
| Common failure modes | Open filament, hairline cracks in the ceramic/glow element, corroded terminals, and short-to-chassis. |
Model Compatibility, Replacement Considerations, Installation Procedure, and Troubleshooting Diagnostics
The 137524000 Frigidaire Washer Dryer Ignitor is the glow-style igniter used in the gas burner module of compatible Frigidaire combination washer‑dryer units. Its primary function is to heat to a temperature that allows the gas valve to open and produce a sustained flame; under normal operation the element will glow brightly within a few seconds of energization and remain stable while the gas valve is open. compatibility depends on the burner housing,connector type,and mounting bracket orientation rather than simply chassis model numbers,so technicians should cross-reference the 137524000 part number with the appliance’s model plate and wiring harness. Physically identical ignitors from the same OEM family are often interchangeable across related brands, but confirm the electrical connector, lead length, and presence of an integrated flame sensor or shield before installing as a replacement.
For removal and troubleshooting, first take appropriate isolation steps: disconnect electrical power and shut off the gas supply before opening the burner access panel. Typical diagnostics include a continuity check across the ignitor element (an open circuit indicates a failed element), a live-voltage check at the ignitor connector during a call for heat, and observation of the ignitor glow versus flame ignition timing. If the element glows but no flame appears, verify gas valve coil continuity and gas pressure; if the element fails to glow but line voltage is present, replace the ignitor.Practical installation notes: handle the new element by the mounting tabs (avoid direct contact with the ceramic/glass surface), torque fasteners to seat the element without stressing the ceramic, and confirm correct routing of thermocouple/flame-sensing leads before reassembly.
- No heat and no glow: check continuity of the ignitor and presence of line voltage at the connector during a heat cycle.
- Ignitor glows but no flame: inspect gas valve coils, gas supply, and flame sensor alignment.
- Intermittent heating: look for cracked element, loose connector, or a failing control/relay.
- Replacement fit issues: compare mounting tab spacing and connector type to avoid stress on the element.
| Item | Description |
|---|---|
| Compatibility | confirm part cross‑reference with appliance model plate; verify connector, lead length, and mounting bracket match. |
| Electrical test | Check for continuity through the element and measure for line voltage at the connector during a start cycle. |
| Common failure modes | Open or cracked element, degraded heating surface, damaged connector, or vibration‑induced fractures. |
| Installation note | Do not touch the glass/ceramic surface; secure mounting to prevent element stress and ensure correct sensor placement. |
Q&A
What is the 137524000 Frigidaire ignitor and what does it do?
The 137524000 is a glow‑bar ignitor used in Frigidaire (and some related brand) gas dryers.When the dryer calls for heat the control sends current to the ignitor,it heats and glows,and that hot element opens the gas valve and/or lights the gas. It is not used in electric dryers – it is specific to the gas side of a washer‑dryer or dryer unit.
How do I know if the ignitor has failed?
Common symptoms of a failed ignitor are no heat from the dryer while the drum tumbles, a clicking sound with no ignition, or the dryer taking long cycles without producing heat. Visual signs include a cracked or broken ceramic/glass element, heavy blackening, or any physical break. An ignitor that measures open (no continuity) with a multimeter is also failed.
Can I test the ignitor with a multimeter, and what readings indicate a good part?
Yes – with the dryer disconnected from power, remove the ignitor and measure resistance across its terminals. A working glow ignitor usually shows continuity and a relatively low resistance (commonly in the range of several to a few hundred ohms depending on the design). If the meter shows infinite resistance (open circuit) the ignitor is bad. Do not attempt to test by applying mains voltage – that is dangerous and can destroy the part.
How tough is it to replace the 137524000 ignitor and what are the basic steps?
Replacement is a moderate DIY job for someone pleasant with appliances. Basic steps: 1) disconnect electrical power and shut off the gas supply,2) access the ignitor by removing the appropriate dryer panel (front or lower access panel),3) disconnect the wiring and mounting screws and remove the old ignitor,4) install the new ignitor without touching the ceramic/glowing surface with bare hands,reconnect wiring and reassemble,5) restore power and gas and test for correct ignition and no gas leaks. Follow the specific model’s service manual and safety procedures.
Why should I avoid touching the ignitor element with my fingers?
Skin oils and contaminants can create hot spots on the fragile ceramic or silicon nitride surface, causing the element to crack or fail prematurely.Handle the ignitor by its mounting bracket or use gloves, and keep the glowing surface clean.
If I replace the ignitor but the dryer still won’t heat, what else should I check?
If a new ignitor doesn’t restore heating, check the following: gas supply and shutoff valve, gas valve coils/solenoids, flame sensor/thermistor, high‑limit thermostat or thermal fuse, cycling thermostat, wiring and connectors, and the dryer control board. Also confirm the ignitor is mounted correctly and the gas is on. A technician’s diagnostic sequence and a gas leak check are advised if you’re unsure.
Is the 137524000 an OEM part and should I use OEM vs aftermarket?
137524000 is an OEM (Frigidaire) part number. OEM parts are made to original specifications and are generally recommended for correct fit and reliable operation. Some aftermarket parts are equivalent and cheaper, but verify fitment, quality, and warranty before buying.Always match the part to your dryer’s exact model number.
How can I confirm the 137524000 is compatible with my dryer model?
Compatibility should be verified using your dryer’s model number (usually on a tag inside the door opening or on the back panel). Check Frigidaire’s official parts list, the appliance’s owner/service manual, or a reputable parts distributor cross‑reference. Do not rely on appliance brand alone - the same brand can use different ignitors for different models.
