137116700 Frigidaire Washer Thermostat is a temperature-control device used in select Frigidaire washing machines. It functions as a temperature sensor/thermostatic switch that provides either a change in resistance or an open/closed contact to the appliance control system, allowing the washer to detect and respond to tub or heater temperature during wash cycles.
Inside the appliance, the thermostat interfaces directly with the heater assembly (where fitted), the main control board, and the wiring harness; it can serve both as an operational sensor that helps the control board achieve target water temperatures and as a safety high-limit that interrupts heater power if temperatures exceed safe limits. Physically it is typically mounted adjacent to the heater element or in a location that accurately samples tub temperature, and its correct operation affects water temperature control, cycle timing, and over-temperature protection.
In this article you will find a technical overview of the 137116700 thermostat’s function and typical electrical/thermal characteristics, guidance on model compatibility and identification, common failure symptoms (such as no heating, incorrect water temperature, fault codes or open/short readings), step-by-step troubleshooting methods including continuity and resistance checks with a multimeter, and practical replacement considerations such as correct mounting, connector matching, and electrical safety procedures.

Function and Role of the Thermostat in Washer Water-Temperature Regulation
The 137116700 Frigidaire Washer Thermostat is a temperature-actuated switch that provides a direct measure of wash-tub water temperature and communicates that information to the washer’s control system. Mechanically it typically contains a temperature-sensitive element (bimetal disc or thermistor assembly) that changes state at predefined setpoints; electrically this change either completes or interrupts a circuit to the main control board or to a heater relay or mixing-valve actuator. In practical operation the thermostat prevents incorrect cycle selection by confirming that the water has reached the requested temperature (for example, allowing a hot-wash fill to proceed only after the element senses the higher temperature) and can also act as a safety interlock on models equipped with internal heating elements.
- Senses water temperature and changes electrical state at setpoints
- Provides input to the electronic control or directly drives valve/heater circuits
- Common failure symptoms: incorrect water temperature, stalls during fill, or intermittent continuity
- Replacement requires matching mounting, terminal configuration, and electrical ratings to the original part
| Item | Description |
|---|---|
| Type | Temperature-actuated switch (bimetal or thermistor-based), direct or low-voltage interface |
| Function | Signals control to start/stop inlet valves or heater and verifies temperature for cycle logic |
| typical diagnostic check | Measure continuity or resistance at ambient and elevated temperatures; compare against service data |
For service and compatibility, technicians should verify that the replacement part matches the original’s terminal layout, mounting bracket, and voltage/current ratings before installation; cross-referencing the model number and performing an on-bench continuity/temperature check speeds diagnosis.A practical troubleshooting sequence is to confirm correct inlet valve operation and water supply temperature first, then verify the thermostat’s electrical response with a multimeter while introducing a controlled temperature change (for example, warm water applied to the sensor); persistent mismatch between measured temperature and control input indicates a failed thermostat or connector/harness fault rather than a control-board logic issue.
How the 137116700 Frigidaire Washer Thermostat Works Inside the Appliance
The 137116700 Frigidaire Washer Thermostat is a temperature-actuated switch mounted against the washer tub or heater housing that governs heating behavior and serves as a high-limit safety in many frigidaire top- and front-load models. Functionally it operates as a simple open/closed contact: it closes when the sensed temperature is below its setpoint to enable the heater circuit (or to signal the controller to continue heating) and opens at the rated temperature to interrupt the circuit and prevent overheating. Correct operation depends on tight thermal coupling to the tub or heater surface and on matching the thermostat’s mounting clip and connector type to the washer model for reliable readings and electrical connections.
Inside the appliance the thermostat’s state directly affects cycle temperature control and safety sequencing. During a hot-wash sequence the control board or timer will energize the heater until the thermostat opens at its design temperature; if the thermostat fails closed, the heater may remain energized and trip a secondary safety, while a failed-open thermostat will prevent the heater from coming on. Technicians test the part with a continuity check at ambient temperature and after applying controlled heat, inspect for corroded contacts or broken mounting hardware, and verify compatibility with the washer’s control scheme (mechanical vs. electronic sensing) before replacement to restore proper regulation and safety.
- Primary function: thermostatic switch for heater enable and/or high-limit protection.
- Common failure symptoms: no heat during hot cycles, heater running continuously, or intermittent heating.
- Field test: continuity at cold, opens at rated temperature when heated; verify thermal coupling.
- Replacement considerations: match mounting,connector type,and specified temperature rating for the washer model.

common Failure Symptoms and Electrical Indicators of a Faulty Washer Thermostat
137116700 Frigidaire Washer Thermostat serves as the washer’s temperature sensor/switch that provides the control board with a signal used to regulate water temperature selection and, on models equipped with a heater or sanitize function, to enable or disable the heating element. In operation the component either changes its electrical continuity or its resistance in relation to temperature; the control board interprets that change to open/close valves or switch the heater.When replacing or diagnosing this part, confirm the connector type and mounting orientation against the machine’s parts diagram because mechanical thermostats and electronic thermistors behave differently and are not universally interchangeable across all Frigidaire models.
- Incorrect or inconsistent water temperature despite correct cycle selection (cold set but lukewarm water, or hot set but no heating).
- Cycles that stall or refuse to advance during temperature-sensitive portions (e.g., sanitize or heavy soil cycles).
- Temperature-related error codes on the control display or repeated attempts to reheat without reaching the setpoint.
- Intermittent behavior: machine works normally sometimes and fails unpredictably,suggesting a failing contact or thermistor drift.
- Visible damage, corrosion at the connector, or a burnt odor near the thermostat assembly.
| Item | Description |
|---|---|
| Multimeter check | Measure continuity/resistance with the component disconnected. A mechanical thermostat should change from open to closed at its actuating temperature; an electronic thermistor will show a predictable change in resistance with temperature (resistance decreases as temperature rises for NTC types). An open circuit at all temperatures or a short to chassis ground indicates failure. |
For practical troubleshooting, use a diagnostic sequence: confirm symptom reproducibility, inspect connectors for corrosion or loose pins, then perform a cold and warm resistance/continuity test with a reliable meter. If readings do not change as expected or if continuity is present when it should be open (or vice versa), replace the thermostat rather than attempting repair; intermittent electrical characteristics often signal degraded internal contacts or a failed sensing element. After replacement, verify correct operation by running a temperature-specific cycle and observing both the control board response and the actual water temperature at the inlet and tub.
Replacement Considerations and Step-by-Step Installation for the 137116700 Thermostat
The 137116700 Frigidaire Washer Thermostat is a temperature-actuated switching device that monitors and controls water temperature or heater operation within compatible Frigidaire washer models. It operates by opening or closing electrical contacts at a calibrated setpoint, allowing the control board or heater circuit to maintain programmed wash and rinse temperatures. technicians should evaluate behavior such as lack of heater activation, persistent cold washes, or intermittent temperature faults as indicative of thermostat wear or contact degradation. Compatibility depends on mechanical mounting, terminal style, and setpoint calibration rather than just the part number; confirm that replacement units match the original’s mounting tabs, connector type, and rated temperature range before installation.
Replacement requires basic electrical troubleshooting,physical disassembly of the control or heater housing,and careful reassembly to preserve wiring routing and seals. Before removing the old thermostat, document terminal positions and take photos of the harness; after removal, verify continuity across the thermostat at ambient temperature with a multimeter and compare behavior to the expected switch action (closed or open at room temperature depending on design). Disconnect power and water supply before starting work, use insulated tools around live circuits, and verify the new thermostat sits flush against the mounting surface to ensure accurate temperature sensing. After installation,run a controlled test cycle and monitor heater operation and cycle temperature to confirm the replacement restores normal function without causing nuisance trips or overheating.
- Disconnect power and water supply, then remove the access panel exposing the thermostat location.
- Document wiring and terminal positions (photos recommended), then gently disconnect terminals and any retaining clips.
- Unfasten mounting screws and remove the old thermostat; inspect mounting surface and gaskets for corrosion or damage.
- Measure the old thermostat for continuity or open/closed status at ambient temperature to confirm failure mode.
- Install the new 137116700 Frigidaire Washer Thermostat, ensuring correct orientation and secure mounting to provide proper thermal contact.
- Reconnect terminals per documentation, reassemble panels, restore power, and run a diagnostic or heated cycle while observing heater engagement and temperature behavior.

Q&A
What is the Frigidaire part 137116700 and what dose it do in a washer?
Part 137116700 is a temperature sensing/control device used on some Frigidaire washing machines to monitor water or tub temperature and tell the control board when to heat,when to change cycles,or whether a selected temperature has been reached. depending on the model it can be a simple temperature switch (thermostat) or a thermistor-style sensor that changes resistance with temperature.
How do I know if 137116700 is compatible with my Frigidaire washer?
verify compatibility by checking your washer’s model number against the part number in the appliance’s parts list or on the Frigidaire/owner/service manual parts diagram. You can also enter your washer model on reputable parts retailer sites to confirm the part fits. Do not rely solely on visual similarity; the correct electrical characteristics (connector type, mounting location, temperature rating) must match.
What are common symptoms of a failing 137116700 thermostat/sensor?
Typical symptoms include the washer not recognizing water temperature selections,failure to advance cycles tied to temperature,the heater not turning on when it should,incorrect temperature error codes,or the machine finishing cycles with unexpectedly cold or hot water. Intermittent operation or erratic cycle behavior can also indicate a failing sensor.
how can a technician test the 137116700 thermostat/sensor?
Always disconnect power before testing. Remove access to the sensor and inspect for corrosion or loose connectors. For a switch-type thermostat, test for continuity with a multimeter at room temperature (it will usually be closed or open depending on the design) and verify it changes state at its rated temperature. For a thermistor, measure resistance at a known temperature (room temp) and then apply heat (carefully with warm water) to confirm the resistance changes predictably. Compare readings to the specification in the service manual-if you don’t have specs, replacement is recommended if readings are inconsistent or unchanged with temperature.
Can I bypass the thermostat/sensor to get the washer working temporarily?
Bypassing a temperature sensor is not recommended except for a brief diagnostic test. Jumping terminals may allow the washer to run or call for heat, but it can defeat safety features and lead to overheating or incorrect cycle operation.If you do perform a diagnostic jumper, do so only briefly and with power disconnected when connecting/disconnecting.Replace the failed part rather than leaving a bypass in place.
How do I replace the 137116700 thermostat/sensor safely?
Turn off and unplug the washer and shut off the water supply. Access the sensor per your model’s service instructions (usually through the control panel, top panel, or rear access). Disconnect the wiring harness, remove any mounting screws or clips, and install the new sensor in the same position and orientation. Reconnect the harness, reassemble panels, restore power, and run a test cycle. Use insulated tools and avoid working on an energized appliance.
