137032600 Frigidaire Washer Dryer Thermal Limiter is a temperature-protection device used in Frigidaire combination washer‑dryer units and similar appliances. It is a thermal limiter (also referred to as a thermal cutout or thermal fuse) designed to interrupt the electrical circuit to the heater or associated control circuitry when temperatures exceed a predetermined safe threshold. The component is typically a small, wire‑lead device mounted to the heater housing or ducting and installed in series with the heating element or heater relay coil.
Inside the appliance, the thermal limiter monitors localized temperature conditions and interacts directly with the heating subsystem and indirectly with airflow and control electronics. When the limiter detects an overtemperature condition it opens the circuit to stop current flow to the heater, preventing sustained overheating that can damage insulation, wiring, or surrounding components and reducing fire risk. it works in concert with the thermostat(s), blower and venting system, and the main control board or relay; a fault in any of those systems (restricted airflow, failed thermostat, or shorted heater) can cause the limiter to open.
This article will explain how the 137032600 thermal limiter functions, how to identify which models and assemblies use it, and what typical failure symptoms look like (for example, no heat or intermittent heating). It will provide practical diagnostic context for technicians and owners – continuity checks, inspection of mounting and airflow, and correlation with other system faults - and cover replacement considerations such as verifying part compatibility, correct mounting and wiring, and safety precautions to observe during service.

function and Role of the Thermal Limiter in Frigidaire Washer-Dryer Safety and Heat Control
The 137032600 Frigidaire Washer Dryer Thermal Limiter is a temperature-actuated protective device mounted in the dryer/heater assembly to interrupt the heating circuit when localized temperatures exceed its design setpoint. In practice it acts as a last-line safety cutoff: when sensing an over-temperature condition it opens the electrical path to the heating element (or secondary heater control), preventing thermal runaway and reducing fire risk. The component is typically a small cartridge-style thermal cutoff or thermal switch with spade terminals,installed in series with the heater; its correct operation depends on good thermal contact with the heater housing and intact electrical connections.
Behavior and compatibility considerations determine both diagnostics and replacement strategy. Some thermal limiters are one-time non-resettable cutoffs while others are resettable bi-metal thermostats, so confirm the device markings and service manual before substituting parts. Common field symptoms include a dryer that runs but produces no heat, a permanently open circuit when measured with a multimeter at ambient temperature, or repeated trips after resolving lint/venting restrictions. When replacing the limiter, match the OEM part number, mounting style, and rated trip temperature rather than substituting a visually similar device; also correct any airflow or insulation faults that caused the limiter to actuate to avoid repeat failures.
- No heat while drum motor runs – thermal limiter likely open
- Continuity present at room temperature; opens when heated during test
- Visible discoloration, melted terminals, or charring indicate thermal failure
- Replace with identical trip-rating and connector style; fix venting/airflow before reassembly

How the 137032600 Frigidaire Washer Dryer Thermal Limiter Functions Within the appliance’s Heating and Safety Circuits
The 137032600 Frigidaire Washer Dryer Thermal Limiter functions as a temperature-actuated safety device placed in the dryer/heater assembly to interrupt power when the local air or component temperature exceeds the design threshold. in typical Frigidaire designs this limiter is wired in series with the heater relay or element; when the limiter opens it removes drive to the heating element and,depending on the model,may also send an open-sense to the control board that prevents further heating cycles. The component’s construction and reset behavior vary by model: some limiters are non-resettable thermal fuses that require replacement after a trip, while others are auto-resetting thermostats. Confirm the exact type and replacement part by cross-referencing the appliance model wiring diagram and parts list before servicing.
Within the appliance’s heating and safety circuits the limiter provides a final overtemperature cutout downstream of cycling thermostats and upstream of user controls. A properly functioning limiter will show near-zero resistance with the system cold and open-circuit after a legitimate overtemperature event; a persistent open reading at ambient temperature indicates failure. Technicians typically verify the limiter with a multimeter for continuity, inspect surrounding insulation and ducting for lint blockages or restricted airflow that could have caused overheating, and replace the limiter with a correct-spec part if tripped or damaged. Replacing the limiter without correcting the root cause (blocked venting, failed blower, or a shorted heating element) will allow the condition to recur.

Common Failure Symptoms and Diagnostic Indicators of a Faulty Thermal Limiter
The 137032600 frigidaire Washer Dryer Thermal Limiter is a temperature-sensing safety device installed in the dryer heating circuit that opens the circuit when local temperatures exceed its rated threshold. It is not a cycling thermostat; rather it functions as a protective cutoff to prevent excessive heat from damaging the heating element, wiring, and drum components. technicians should treat this limiter as a single point of failure in the heater path-if the limiter has opened it will remove power to the heater nonetheless of control board signals, and the part must be replaced if it shows an open condition when cold or visible signs of thermal damage are present.
Common operational symptoms point to the limiter rather than to controls or the heating element itself: complete loss of heat with normal drum motor operation, intermittent heating that resumes only after a cool-down period, or visible charring/corrosion at the limiter terminals. For diagnostics, first disconnect power and perform a visual inspection for discoloration, deformation, or burned connectors. A handheld multimeter continuity check at ambient temperature is the primary test – a healthy limiter will read as a closed circuit at room temperature and open once it has been exposed to an over-temperature condition. Also verify upstream conditions that can cause nuisance trips (blocked venting,failing blower,or shorted heating element) before replacing the limiter to avoid repeated failures.
- No heat while the drum motor runs normally.
- Intermittent heating that stops after the dryer warms and then may resume after cooling.
- Open circuit reading on a multimeter at ambient temperature.
- Visible discoloration, melting, or burned terminals at the limiter assembly.

Replacement Considerations, Wiring Verification and Installation Best Practices for the Thermal Limiter
The 137032600 Frigidaire Washer Dryer Thermal Limiter is a temperature-actuated protective device placed in the dryer/heater circuit to interrupt power when localized temperatures exceed the design threshold. In operation the limiter is normally a closed contact (or conductive element) that opens at its rated trip point to prevent overheating of the heating element or nearby wiring; many limiters are single-use thermal cutouts and must be replaced after they open. When replacing this part, match the OEM temperature rating, physical mounting, and terminal type rather than relying solely on visual similarity, because mismatched ratings can cause nuisance openings or fail to provide the intended over-temperature protection on the appliance model you are servicing.
Follow a systematic verification and installation workflow to ensure correct function and safe wiring: disconnect mains power, confirm the limiter is the correct OEM part for the model, verify continuity at ambient temperature (a closed circuit indicates the limiter has not opened), and confirm the replacement uses compatible spade terminal sizes or that properly crimped connectors are used. Maintain proper clearance from the heating element and secure the limiter to its bracket to avoid mechanical stress; strain relief on the harness and correct wire routing reduce heat soak and chafing. After installation perform a functional check with the dryer running an empty heat cycle while monitoring current draw and ensuring the thermal limiter does not experience unintended heat exposure. Practical checklist:
- Power removed and panel access secured before any work.
- Continuity check of the limiter at room temperature (expect closed if unused).
- Use OEM-matching terminal size or properly crimped quick-disconnects.
- Mount securely with original bracket orientation and avoid contact with the heater housing.
- Post-installation functional heat cycle and visual inspection for hot spots.

Q&A
What is the Frigidaire part 137032600 (thermal limiter) and what does it do?
Part 137032600 is a thermal limiter (also called a thermal cutoff or high-limit thermostat) used on frigidaire washer‑dryer combos and some standalone dryers. its job is to cut power to the dryer’s heating circuit if temperatures exceed a safe threshold, preventing overheating and reducing the risk of fire or damage to components.
What symptoms indicate the thermal limiter has failed?
Common symptoms include: the dryer tumbles but produces no heat; the unit stops heating intermittently or shuts down mid‑cycle; or the dryer won’t run the heater while other functions operate normally. A blown thermal limiter usually causes an open circuit in the heating circuit, so the heating element (or gas valve on gas models) receives no power.
Where is the thermal limiter located on Frigidaire washer‑dryers?
Location varies by model, but it is typically mounted on or near the heater housing, the blower housing, or the exhaust duct inside the dryer section. Access usually requires removing the rear panel or front lower access panel. Consult yoru model’s service manual or parts diagram to find the exact location for your machine.
How can I test the thermal limiter to see if it’s bad?
Always disconnect power before testing. Remove the wires from the limiter terminals (note their positions or take a photo). Use a multimeter set to continuity or low ohms: a good thermal limiter will show continuity (near 0 ohms). An open reading (infinite resistance/no continuity) means the limiter has blown and should be replaced. you can also check for voltage upstream/downstream with the dryer powered (technician only) to verify where the circuit opens, but don’t probe live circuits unless you are qualified.
Is the 137032600 thermal limiter resettable, or must it be replaced?
Most thermal limiters used as safety cutouts are non‑resettable one‑time devices (thermal fuses) and must be replaced if they open. Some thermostats used for temperature regulation are resettable; check your part description or service manual. For safety, if 137032600 opens it should be replaced with the correct OEM part rather than attempting a repair or temporary reset.
How do I replace the thermal limiter safely?
Turn off and unplug the appliance (or shut off power at the breaker). Access the limiter by removing the appropriate panel(s). Disconnect the wiring (take pictures or label leads), remove mounting screws, and swap in the new 137032600 part. Reconnect wires to the correct terminals, reassemble panels, and restore power. After replacement, run the dryer to verify proper heating. If you’re not pleasant performing this work, hire a qualified appliance technician.
What commonly causes a thermal limiter to blow, and how can I prevent it from happening again?
Thermal limiters most frequently enough blow as of overheating caused by restricted airflow (blocked or kinked venting, clogged lint screen, full lint trap, or obstructed vents), a failing heating element that shorts or overheats, or a faulty thermostat. To prevent recurrence: clean the lint screen after every use, inspect and clean dryer venting regularly (outdoor vent and ducting), ensure the blower and housing are clear, and have the heater and thermostats checked if limits continue to open.
Is part 137032600 compatible with my Frigidaire model and how much will it cost?
Compatibility depends on your exact Frigidaire model number. Always verify the part 137032600 against your model’s parts list or with an authorized parts dealer before purchasing. Prices vary by supplier but thermal limiters typically sell in the low tens of dollars (frequently enough around $10-$40). buy OEM or a trusted equivalent and confirm return policies in case of compatibility issues.
Can I bypass the thermal limiter to get the dryer working?
Do not bypass the thermal limiter. It is indeed a critical safety device designed to prevent fires and overheating. Bypassing it is dangerous, illegal in some areas, will void warranties, and can lead to equipment damage or fire. If the limiter has blown, replace it with the correct part and address the underlying cause of overheating.
The Way Forward
The 137032600 Frigidaire washer-dryer thermal limiter is a critical safety and performance component designed to interrupt power to the heating circuit if temperatures exceed safe limits. By preventing overheating, it protects the appliance, its electrical components and the surrounding environment, contributes to consistent drying performance, and helps avoid damage to clothing and potential fire hazards. Its correct function is thus integral to the safe, efficient operation of Frigidaire washer-dryer units.
Because symptoms of a failing thermal limiter can mimic other heating or control issues,proper diagnosis is essential before replacement; accurate testing and inspection of related parts (heating element,thermostats,wiring and control boards) reduces unnecessary parts replacement and recurring faults. When replacement is required, using the correct 137032600 part and following manufacturer installation and safety guidelines – or engaging a qualified technician – ensures reliable restoration of function. Timely, informed attention to the thermal limiter supports appliance longevity, operational safety, and consistent performance.
