Assy-Case Sensor Parts

This heater thermistor is a temperature-sensing replacement part that helps the appliance monitor and regulate heating. Replacing a failed thermistor restores accurate temperature feedback for safer, more consistent operation. What it does

• Measures temperature near the heater and sends a signal to the control board.
• Helps the unit cycle heating on and off to maintain proper operating temperature.
• Common symptom: appliance won't heat or heats intermittently.
• Common symptom: cycles too frequently or shows error codes related to temperature sensing.

• One heater thermistor.

• Disconnect power before accessing or replacing the thermistor.
• Handle the sensor and connector carefully to avoid damage to the lead or plug.
• Verify connector orientation and secure wiring; do not force connectors.

Dryer not heating or drying inconsistently? A faulty thermistor causes temperature control issues. Direct repair—moderate difficulty, 30-45 minutes.

Fix ice buildup on evaporator coils or freezer not defrosting properly. This defrost thermostat monitors temperature to prevent frost. 2-hour repair.

Washer not heating water or showing tE error? This temperature sensor monitors water temp and signals the control board. Moderate DIY repair fixes temp issues.

This Thermostat Assembly monitors and regulates internal temperature within the appliance's heating circuit. Replacing a failed thermostat restores proper heat control, helps prevent overheating, and can resolve common heating performance issues so cycles run correctly. What it does

• Senses internal temperature and opens/closes the heater circuit to maintain proper heat
• Provides over-temperature protection by cutting power at unsafe temperatures
• Helps ensure consistent heating performance throughout the cycle
• Helps with symptoms such as no heat, overheating/shutting off, or unusually long cycle times

• 1 thermostat assembly

• Disconnect power before servicing; allow hot components to cool
• Access the thermostat location (varies by model); note wire positions before removal
• Mount flush to the surface for accurate sensing; transfer original hardware if required
• After installation, test operation; use a multimeter for continuity checks if needed

This defrost thermostat with attached wiring harness monitors the evaporator coil temperature and signals the defrost heater to turn on or off during the defrost cycle. It is typically mounted on or near the evaporator coils inside the freezer compartment. Replace this part if the refrigerator is not cooling properly, frost is building up excessively on the evaporator coils, or the defrost cycle is not functioning correctly.

Dryer not heating or overheating? This high-limit thermostat cuts power when temperatures exceed safe levels. Common fix for no heat issues.

Fixes refrigerator not cooling or excess frost buildup. This defrost thermostat regulates the defrost cycle. DIY-friendly repair, takes about 20 minutes.

Dishwasher won't power on? This inline fuse protects your dishwasher's wiring harness from electrical overload. Restores circuit protection quickly.

This thermistor senses the temperature inside the refrigerator bin/drawer and provides the control board with the signal it needs to regulate cooling. Replacing a bad thermistor restores accurate temperature readings and more consistent cooling. What it does:

• Measures bin/drawer temperature and sends a voltage/ohm signal to the control board.
• Helps the refrigerator maintain set temperatures by enabling proper compressor/fan control.
• Common symptoms of a failing thermistor: incorrect bin temps, inconsistent cooling, or temperature-related error codes.
• Use when diagnostics point to a faulty temperature sensor or when the thermistor is damaged.

• Always disconnect power to the appliance before starting any repair.
• Handle the sensor and wiring gently; avoid contaminating or bending the sensing tip.
• Reconnect using the original connector and route the harness the same way to prevent pinching.

This is a cycling thermostat that monitors the temperature inside the dryer drum and signals the heating element to turn on and off to maintain the selected drying temperature. It is typically mounted on the blower housing or exhaust duct. Replace this part if your dryer is not heating, overheating, running too hot or too cool, or if clothes are taking too long to dry.

This internal-bias thermostat senses oven temperature and helps the control board maintain the set heat level. Replacing a failing thermostat restores more consistent temperature control and more reliable cooking results. What it does:

• Senses cavity temperature and signals the control to cycle the heating element or burner
• Regulates heating cycles so the oven reaches and holds the set temperature
• Common symptoms: oven takes too long to heat, temperature fluctuates or runs too hot, or the oven cycles on/off erratically

• Disconnect power (unplug or shut off circuit breaker) before servicing to avoid shock
• Access location varies by model—part is typically mounted near the control or inside the oven cavity housing
• Handle the sensor element and terminals carefully to avoid damage; reuse of mounting hardware depends on your model

Fix frost buildup and poor cooling in your refrigerator. This defrost thermostat prevents ice accumulation on the evaporator. Moderate DIY repair.
