Assy-Case Sensor Parts

This mechanical temperature control thermostat replaces the factory temperature sensing switch to restore proper refrigerator temperature regulation. It helps the appliance maintain set temperatures for safe food storage and normal cooling performance. What it does:

• Senses cabinet temperature and opens/closes the cooling circuit to regulate compressor run time.
• Commonly used when the refrigerator runs constantly or cycles too quickly.
• Works as the user-adjustable temperature control for manual-style refrigerator controls.

• Disconnect power to the appliance before starting any repair.
• Handle the sensing bulb/capillary tube gently; avoid kinks or sharp bends.
• Verify correct placement of the sensing bulb in the evaporator/probe clip per OEM location.

This is a thermistor-style temperature sensor that monitors the internal temperature of the refrigerator compartment. It sends temperature readings to the main control board, which uses that data to regulate the compressor and defrost cycles. Replace this sensor if the refrigerator is running too cold, too warm, or cycling erratically despite correct thermostat settings.

This thermistor measures temperature changes inside your microwave to control cooking functions and safety systems. It sends temperature readings to the control board to adjust power levels and cooking times. Replace this part if your microwave doesn't heat properly, overheats, or sensor cooking features don't work correctly.

Fix uneven cooking or incorrect oven temperatures with this temperature sensor. Detects cavity temperature for accurate bake cycles. Easy DIY repair.

This humidity sensor detects moisture levels inside the microwave cavity during cooking. It allows the microwave to automatically adjust cooking time and power when using sensor-cook or auto-reheat functions. Replace this sensor if your microwave consistently overcooks or undercooks food on sensor settings, or if you receive error codes related to the humidity sensor.

Fix dishwasher heating issues with this thermistor and high-limit thermostat assembly. Restores proper temperature control and prevents overheating.

This is a humidity sensor that detects steam levels inside the microwave cavity during cooking. It communicates moisture readings to the control board, allowing auto-cook and sensor-reheat functions to determine when food is done. Replace this sensor if your microwave's auto-cook cycles run too long or too short, or if sensor cooking modes no longer work properly.

This thermal fuse is a safety device that cuts power to the dryer's heating element if the internal temperature exceeds a safe limit. It is a one-time-use component that cannot be reset once tripped. Replace this part if the dryer runs but produces no heat, or if the dryer does not start at all.

Fixes frost buildup in freezer or warm refrigerator temps caused by failed defrost cycles. This 55-degree thermostat restores proper defrosting.

This thermistor is a temperature-sensing component mounted near the magnetron in the microwave. It monitors the magnetron's temperature and signals the control board to shut off the magnetron if it overheats. Replace this part if the microwave stops heating intermittently, shuts off unexpectedly during use, or displays an error code related to overheating.

This is an electronic thermostat rated at 155°F that monitors and regulates the air temperature inside the dryer drum. It signals the control board to cycle the heating element on and off to maintain proper drying temperatures. Replace this thermostat if your dryer is overheating, not heating at all, or shutting off prematurely during a cycle.

Refrigerator not cooling or frosting up? This defrost thermostat controls when the defrost heater turns off, preventing ice buildup on evaporator coils.
