General Electric Microwave Fuse Or Sensor

This gas sensor monitors moisture levels during sensor-cook cycles so the control can adjust time and power for consistent results. Replacing a failed sensor restores reliable sensor-cook performance. What it does:

• Detects steam/vapor inside the cavity and sends feedback to the control board
• Helps the appliance automatically set or adjust cooking time on sensor settings
• Failure symptoms can include sensor-cook not starting, stopping early, or running too long
• May trigger "Sensor" or general error messages related to sensor-cook functions

• Disconnect power before servicing; if working on a microwave, discharge the high-voltage capacitor
• Access is typically behind the control panel or air channel; avoid touching/contaminating the sensing surface
• Transfer any mounting clips/brackets and ensure the wiring connector is fully seated
• After installation, run a simple sensor-cook test to confirm operation

This NTC thermistor is a temperature sensor that feeds real-time temperature data to the control. Replacing a failing sensor helps restore accurate temperature regulation, reduce nuisance shutdowns, and improve consistent cycle timing and performance.

• Monitors temperature by changing resistance as heat rises or falls
• Sends a signal to the electronic control to manage heating and fan operation
• A failed sensor can cause inaccurate temperatures, short/long cycles, or sensor-related error messages
• May prevent certain cycles from starting

• Disconnect power and allow the appliance to cool completely before servicing
• Note connector orientation and wire routing; take a photo for reference
• Install the sensor in the original location/clip and route wires away from hot or moving parts
• Restore power and run a test cycle to proper temperature response

A temperature sensor assembly that monitors internal temperatures and sends readings to the appliance control so the unit can maintain proper heating or cooling. Replacing a failed sensor restores accurate temperature regulation and consistent performance. What it does

• Detects and reports temperature to the electronic control or thermostat
• Helps the appliance maintain set temperatures for consistent operation
• A faulty sensor can cause inaccurate temperature readings or uneven heating/cooling
• May trigger temperature-related error codes or put the unit into a diagnostic/fail-safe mode

• Disconnect power to the appliance before attempting any repair
• Handle the sensor and its wiring gently; avoid bending or damaging the sensing tip or connectors
• Reconnect wiring securely and confirm correct routing to prevent interference with moving parts

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 gas flame sensor detects whether a burner's flame is present so the range/oven's gas valve and ignition control can operate safely. It helps restore reliable ignition and prevents the valve from staying open when no flame is detected. What it does:

• Senses the presence of a gas flame and signals the control to keep the valve open
• Helps prevent gas flow if a flame is not detected
• Can stop ignition or cause the oven/range not to heat when failing
• Commonly replaced when burners won't stay lit or control shows ignition-related errors

• One gas flame sensor

• Turn off electrical power and shut off the gas supply before servicing
• Handle the sensor and its connector carefully to avoid damage
• Reinstall in the exact position and orientation; loose connections can cause false faults
