137032600 Frigidaire Washer Dryer Thermal Limiter is a temperature-actuated safety device used in Frigidaire combination washer‑dryer units. The component is a thermal cutoff/limiter-typically a small,temperature‑rated switch or fuse mounted in the dryer/heater assembly-that is designed to open an electrical circuit when local temperatures exceed a specified threshold,preventing further heating and reducing the risk of component damage or fire.
Inside the appliance the thermal limiter is installed in series with the dryer’s heating circuit and interacts with related safety and control elements such as the heating element,cycling thermostats,high‑limit thermostats,control relays/boards,and the blower/venting system. its primary role is to monitor air or housing temperature near the heater and interrupt power to the heater (and in some designs the control feed) if airflow is blocked, a thermostat fails, or the element overheats.Proper function depends on correct placement,secure electrical connections,and integration with the unit’s thermal management and venting systems.
In this article you will learn how the 137032600 thermal limiter functions, where it is typically located and how to verify compatibility with specific Frigidaire models, common failure symptoms (for example no heat or repeated thermal trips), and safe troubleshooting procedures including continuity testing and inspection of venting and associated thermostats. The article will also cover practical replacement considerations-matching temperature rating and terminals, mounting orientation, and steps to address root causes that can cause premature limiter failure-so technicians and owners can perform recommended diagnostics and repairs while observing appropriate safety precautions.

Function and Role of the Thermal limiter in Frigidaire washer‑Dryer Safety and Heat Control
The 137032600 Frigidaire Washer Dryer Thermal Limiter is an OEM temperature cutoff device installed in the dryer’s heating circuit to interrupt power if the air temperature or component temperature rises above a predetermined safe threshold. It sits in series with the heater assembly (and in some designs the motor circuit) and physically mounts to the heater housing or ductwork where it senses the local temperature. In practice this limiter prevents sustained over-temperature conditions caused by restricted ventilation, a shorted heating element, or a failed thermostat; when the limiter opens it removes power from the heater so the appliance stops producing heat until the limiter is replaced or, where designed as resettable, until it cools and resets.
Technicians should understand the limiter’s electrical and thermal characteristics before replacing it: match the temperature trip rating, terminal type, and mounting method to the original part to ensure correct operation and compliance with safety design. Use a multimeter to check continuity at ambient temperature (an open circuit normally indicates a blown limiter), and investigate root causes-blocked vents, defective thermostats, or heater shorts-rather than simply replacing the limiter repeatedly. Do not bypass the limiter; substituting a part with a different trip temperature or bypassing it compromises safety. Typical diagnostic symptoms, testing steps, and a rapid reference are listed below to aid repair decisions.
- No heat while the element receives power intermittently or cuts out during cycles.
- Continuity test shows an open circuit at room temperature for the limiter.
- Visible signs of overheating (discoloration, melted terminals) at the limiter or adjacent housing.
- Replacement guidance: use identical part number or equivalent with same temperature rating and connectors; inspect ventilation and heater components before reinstalling.

How the 137032600 Frigidaire Washer Dryer Thermal Limiter Works Inside the Appliance
137032600 frigidaire Washer Dryer Thermal Limiter is a temperature-actuated safety device wired in series with the dryer’s heater circuit (and in some models, the motor circuit) to prevent sustained over-temperature conditions. Internally it functions as a normally-closed contact that opens when the element surrounding the sensor exceeds its rated trip temperature,interrupting power to the heater and stopping heat generation. Depending on the specific appliance design the limiter may be a one-time thermal fuse that must be replaced after it opens, or a resettable bimetal thermal limiter; always confirm the exact type and ratings in the service manual or on the part label before replacing or testing.
The component is typically mounted close to the heating element, blower housing, or exhaust path so it senses actual air/assembly temperatures rather than ambient cabinet heat. For troubleshooting, an open limiter will usually present as no heat while the drum and fans continue to run; intermittent opening can indicate restricted airflow or an overworked element, so correcting venting problems is often required in addition to replacing the limiter. When replacing, match the electrical rating, trip temperature, mounting style, and connector type to maintain safe operation; cross-reference the OEM 137032600 part number against model-specific parts lists to ensure compatibility.
- No heat while drum/motor run
- Intermittent heating cycles correlated with load or vent restriction
- Continuity open at room temperature when tested with a multimeter (indicates a blown limiter)
- Visible discoloration or burn marks near the limiter or heater assembly

Common Failure Symptoms and electrical/Temperature Diagnostic Indicators for the Thermal Limiter
The 137032600 Frigidaire Washer Dryer Thermal Limiter is a temperature-sensing safety device placed in series with the heater circuit to interrupt power if temperatures exceed a safe threshold.In operation it behaves like a normally closed thermal cutoff: at normal operating temperatures it shows continuity and allows the heater to run; if the heater chamber or air-path temperature rises above the limiter’s trip rating the device opens and must be replaced (many thermal limiters are single‑use non‑resettable designs, though some assemblies use resettable thermostats). Verify compatibility by matching connector style, mounting bracket, and the limiter’s specified trip temperature to the appliance model-electrical form factor and thermal rating must match the original to ensure correct protection and reliable operation.
- No heat while motor runs (heater circuit interrupted)
- Intermittent heating or short heating cycles that stop after a period
- Dryer or washer-dryer shutting down during cycle with no motor fault
- Open circuit detected across the limiter when measured cold
Electrical and temperature diagnostics are straightforward: with the appliance disconnected from power, remove or access the limiter and measure continuity or resistance with a multimeter. A healthy thermal limiter typically measures a few ohms or less (near 0 Ω) when cold; an open circuit or infinite resistance indicates the limiter has tripped or failed. For temperature verification use an infrared thermometer or thermocouple at the housing to detect abnormal rises-typical trip temperatures for thermal cutouts used in laundry appliances commonly fall in the low-to-mid hundreds of degrees Celsius, but always confirm the exact trip rating for the replacement part. Also check upstream causes such as blocked vents, failed blower motors, or shorted heating elements, because repeated limiter openings usually indicate a thermal fault elsewhere rather than a defective limiter alone.
| Item | Description |
|---|---|
| Cold continuity | Near 0 Ω (a few ohms or less) indicates a closed circuit; replace if open |
| Tripped state | Open circuit / infinite resistance; typically non‑resettable and requires replacement |
| Typical trip temperature | Example range: ~130-170°C (verify OEM spec for exact 137032600 rating) |
| Compatibility note | Match connector, mounting, and trip rating to the appliance model for proper protection |
Model Compatibility, Replacement and Installation Considerations, and troubleshooting Procedures
The 137032600 Frigidaire Washer Dryer Thermal Limiter is a temperature-actuated safety device that interrupts power to heating elements or motor circuits when internal temperatures exceed safe limits. In practice this limiter is a one-shot or auto-reset thermal switch depending on design; its primary role is to prevent thermal runaway or component damage by opening the circuit at a specified trip temperature and, for auto-reset types, re-closing once temperatures fall below the reset threshold. technicians should verify physical fit, terminal type, and the limiter’s trip temperature and voltage/current ratings against the appliance wiring diagram and replacement parts list before installation, as mismatched ratings or incorrect mounting (such as wrong clip location or threaded stud size) can result in nuisance trips or failure to protect the appliance under fault conditions.
Replacement and troubleshooting require basic electrical checks and attention to installation details. Disconnect power and visually inspect the limiter for thermal discoloration, corrosion, or melted insulation; measure for continuity at room temperature (a healthy closed limiter will show near-zero ohms) and confirm open state under controlled heating if safe to do so. Install the replacement so the thermal sensing element contacts the same surface area as the original (motor housing, heater baffle, or duct surface) and use high-temperature wire and strain reliefs to preserve long-term reliability. Typical diagnostic signs and basic procedures include the following:
- No heat or intermittent operation of the dryer/heater – check limiter continuity and heater circuit resistance.
- Dryer stops mid-cycle while drum and element are hot – suspect an open thermal limiter that trips under load; verify trip temperature and replacement spec.
- Visible damage, charring, or loose terminals - replace with a matching part and ensure correct mounting orientation and secure terminal connections.

| Trip temperature | specified by OEM; verify against service manual before replacing |
| Electrical rating | Voltage and current limits to match heater/motor circuit |
| Typical location | Motor housing, heater housing, or exhaust duct; ensure thermal contact matches original mounting |
Q&A
What is the Frigidaire part 137032600 (thermal limiter) and what does it do?
The 137032600 thermal limiter (thermal cutoff) is an OEM safety device used in frigidaire washer-dryer units to protect the dryer/heater circuit from overheating. It is indeed normally a normally-closed temperature-sensitive switch that opens (cuts power) when a preset temperature is reached, preventing thermal damage or fire.
What symptoms indicate the thermal limiter has failed?
Common symptoms include the dryer not producing heat at all while the drum still tumbles, the dryer stops mid-cycle, or the unit will not power the heating element. In some cases a blown limiter can also be caused by repeated overheating and may accompany a burned or shorted heating element or obstructed venting.
Where is the thermal limiter located on a Frigidaire washer-dryer?
On most frigidaire combo units the thermal limiter is mounted on or near the dryer heater housing, blower housing, or bulkhead where it senses exhaust/heater temperature. Exact location varies by model; consult the model-specific service manual or parts diagram to find the exact mounting point for your machine.
How can I test the thermal limiter to see if it is faulty?
Always disconnect mains power before testing. Remove access to the limiter, disconnect one wire, and use a multimeter set to continuity or ohms. A good thermal limiter at room temperature will usually show continuity (near 0 ohms). An open circuit (infinite resistance) indicates the limiter has blown and must be replaced. Do not test a limiter in-circuit without isolating it first.
Is the thermal limiter resettable or reusable after it trips?
Most thermal limiters/thermal fuses used by Frigidaire are non-resettable (one-shot) devices. Once they open due to overheating, they must be replaced with the correct OEM part-do not bypass or jumper the limiter, as that defeats a critical safety feature.
How do I replace part 137032600 safely?
Disconnect power (and shut off gas if applicable). Verify model-specific access steps and remove the panel to reach the limiter. disconnect the terminals (note wire positions), remove the mounting screw/clamp and install the identical replacement (same part number/spec). Reconnect wiring with proper high-temperature connectors, reassemble panels, and restore power. If you are not comfortable or the unit is gas-fired, have a qualified appliance technician perform the replacement.
What commonly causes a thermal limiter to fail, and how can I prevent it from happening again?
typical causes include restricted exhaust/venting (causing high temperatures), a shorted or partially shorted heating element, faulty cycling thermostat or temperature sensors, or prolonged high-load conditions. To prevent recurrence, clean lint from the drum and vent system, inspect and test the heating element and thermostats, ensure proper vent routing and airflow, and repair any component that causes excessive temperature rise.
Is 137032600 the correct replacement part for my model and where can I verify compatibility?
While 137032600 is an OEM Frigidaire part number, compatibility depends on your appliance model. verify by checking your washer-dryer model number and cross-referencing it on Frigidaire’s official parts site, a trusted parts distributor, or the service manual. Always replace with the exact OEM part number or an approved equivalent to maintain safety and proper operation.
