Assy-Case Sensor Parts

Dryer won't heat or stops when hot? A faulty cycling thermostat disrupts temperature regulation. Testing with a multimeter confirms the issue.

This is a normally open cooling fan thermostat that activates the oven's cooling fan when internal temperatures reach a set threshold. It helps regulate airflow to protect surrounding cabinetry and electronic controls from excessive heat. Replace this thermostat if the cooling fan fails to turn on during or after oven use, or if the fan runs continuously without shutting off.

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

• Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
• Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
• Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
• Use when the existing sensor fails to report correct temperatures or the part number matches.

• Always disconnect power to the appliance before servicing to avoid shock or damage.
• The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
• Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

Fix frost buildup on evaporator coils or warm fridge temps. This defrost thermostat regulates defrost cycle temperature. DIY-friendly, 20-30 min install.

This 120V appliance buzzer provides the audible alert for cycle completion and user notifications, restoring clear beeps when your appliance's buzzer has failed or gone silent. Ideal for ovens, ranges, and similar appliances that use a 120V signal. What it does:

• Produces audible alerts for cycle end, error notifications, and timer signals
• Commonly replaces units that are silent, intermittently loud, or emit distorted/weak tones
• Matches the OEM electrical rating to ensure proper signalling at 120 volts
• Designed for direct replacement of the original buzzer assembly

• Disconnect power to the appliance before servicing to avoid shock hazard
• Minimal tools typically required; handle the part and wiring carefully to avoid damage

If your range meat probe gives inaccurate readings or doesn't work, this temperature sensor monitors internal cooking temps. Easy 15-minute DIY fix.

This SPDT high-amp switch controls high-current circuits by switching one input between two outputs, restoring proper electrical control in affected appliance functions. Built for high-load switching where reliable on/off selection is required. What it does:

• Directs high-current power from a single input to one of two outputs (single-pole, double-throw action)
• Replaces worn or failed selector/limit-style switches that cause intermittent or no power to a circuit
• Commonly used where a high-amp, durable switching contact is required to complete a function
• Helps stop symptoms like intermittent operation, failure to switch between states, or no power to the controlled circuit

• One SPDT high-amp switch (WB24T10160)

• Disconnect power to the appliance before inspecting or replacing the switch
• Verify wiring locations and take a photo before removal for correct reconnection
• Use proper tools and avoid touching energized contacts;

Fix dryer overheating or not heating issues with this thermistor assembly. Monitors temperature throughout drying cycles for proper heat regulation.

Dryer not heating properly or overheating? This cycling thermostat regulates temperature by cycling the heating element on and off. Moderate DIY repair.

This 20-amp circuit breaker restores overcurrent protection to the appliance's electrical circuit, helping prevent damage from short circuits or overloads. It replaces a worn or tripped breaker so the appliance can receive proper power. What it does:

• Acts as an overcurrent safety device that trips when current exceeds safe limits
• Protects wiring and components from damage caused by overloads or short circuits
• Common symptom: appliance won't power on or stops powering intermittently
• Common symptom: breaker repeatedly trips during normal operation

• Disconnect power at the house breaker before inspecting or replacing the part
• Handle terminals carefully; ensure connectors are fully seated and tight
• Replace with the exact part number for fit and proper electrical rating

Fix a dryer that won't heat with this thermostat. Regulates heating element temperature to prevent overheating. Moderate DIY repair in under an hour.

This protective fuse safeguards the appliance's electrical circuit. When an overcurrent or short occurs, it opens the circuit to cut power and help prevent damage. Replacing a blown fuse can restore power once the underlying issue is corrected.

• Opens the circuit when current exceeds its design limit or a short is detected
• Helps protect control and other internal components from electrical damage
• Typical symptoms of a failed fuse include no power, dead display/controls, won't start, or immediate power loss
• An underlying electrical fault is likely present and should be diagnosed

• Disconnect power at the breaker or unplug the appliance before servicing
• Replace only with the exact type and rating specified for your model; never bypass or upsize a fuse
• Inspect wiring and components for the root cause of the blown fuse before restoring power
• If servicing a microwave, follow the service manual and discharge the high-voltage capacitor; consider service due to shock risk

This is a bi-metal defrost thermostat that monitors evaporator coil temperature and signals the defrost heater to turn on or off during the defrost cycle. It helps prevent excessive frost and ice buildup on the evaporator coils. Replace this thermostat if the refrigerator is not cooling properly, frost is building up heavily on the back wall of the freezer, or the defrost cycle is not activating.

Fix TE error code on your washer with this thermistor temperature sensor. Restores accurate temperature sensing and reliable cycle control.

This sensor detects moisture and temperature levels inside the microwave cavity during cooking. It communicates with the control board to regulate automatic cooking and sensor reheat cycles. Replace this part if the microwave fails to properly detect doneness, overcooks or undercooks food on sensor settings, or displays a sensor error code.

This temperature sensor monitors refrigerator temperature and sends readings to the control board so the appliance can regulate cooling. Replacing a failing sensor restores accurate temperature feedback for reliable cooling performance. What it does

• Measures internal temperature and reports it to the refrigerator control board
• Helps the system cycle the compressor and fans correctly for stable temperatures
• Commonly linked to symptoms like poor cooling, frequent compressor run, or temperature-related error codes
• Works as the sensing element for automatic defrost and temperature-control routines

• One temperature sensor (thermistor) with attached lead

• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the sensor and wiring gently; secure the lead per factory routing to avoid contact with moving parts
• May require basic hand tools and access to the evaporator/thermostat area
