Sensor & Thermistor

Fix F4 error codes or sensor cook failures with this microwave humidity sensor. Restores automatic cooking cycles. Moderate DIY difficulty.

Fix sensor cook cycles that won't adjust properly or show sensor errors. This humidity sensor monitors moisture levels for automatic cooking adjustments.

The NTC thermistor is a temperature sensor located near the microwave's magnetron that monitors internal temperature for proper cooking control. Replace when food cooks unevenly, the microwave overheats, shuts off unexpectedly, or displays temperature-related error codes.

This humidity sensor detects moisture levels inside the microwave cavity during cooking, allowing the control board to automatically adjust cook time and power. It is typically mounted inside the cooking compartment or vent area. Replace this sensor if your microwave's auto-cook or sensor-cook modes no longer work correctly, food is consistently overcooked or undercooked, or the unit displays a sensor error code.

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.

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 thermistor is the sensor that lets the control board monitor and regulate appliance temperature for reliable cooling performance. Replacing a failing thermistor can restore proper temperature control and cycling. What it does:

• Senses internal temperature and sends readings to the control board
• Helps the compressor, fans, and defrost system run at the right times
• Commonly linked to symptoms like incorrect temperatures, overcooling, or frequent on/off cycling
• A faulty thermistor can cause improper defrost timing or erratic cooling behavior

• Disconnect power before inspecting or replacing the sensor to avoid shock
• Handle the sensor and wiring connector gently to avoid damage
• Mount the sensor in the original location and secure wiring per OEM routing

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.

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.

Fix microwave overheating or uneven cooking with this thermistor. Monitors oven temperature for proper operation. Simple DIY repair in 15-20 minutes.

Microwave not heating evenly or shutting off early? This sensor monitors temperature to control cooking. Common DIY fix for heating issues.

This sensor detects moisture levels inside the microwave cavity during cooking and communicates with the control board to adjust cook times automatically. It is a key component for auto-cook and sensor-reheat functions. Replace this sensor if the microwave fails to properly detect doneness, overcooks or undercooks food on sensor settings, or displays a sensor error code.
