Defrost Parts

This is a thermostat that monitors the temperature in the ice maker to signal when ice has fully frozen and is ready to be harvested. It acts as a thermal cutoff device to regulate the ice-making cycle. Replace this thermostat if the ice maker stops producing ice, runs continuously without cycling, or fails to eject ice at the proper time.

Fix ice buildup and poor cooling caused by a faulty evaporator defrost heater. This heater melts frost during defrost cycles to restore proper airflow.

Fixes frost buildup and warm refrigerator temps caused by failed defrost heater. Restores normal cooling and airflow. Moderate DIY repair, 30-60 minutes.

Fix ice buildup and frozen water dispenser issues with this dispenser heater kit. Prevents frost clogging in the chute and valve area. Moderate DIY repair.

This temperature sensor (thermistor) detects internal appliance temperature and sends readings to the control board so the unit maintains proper cooling. Replacing a failing sensor restores accurate temperature monitoring and helps prevent spoilage. What it does:

• Measures internal temperature and provides a resistance-based signal to the control board
• Helps the control system regulate compressor and defrost cycles
• Commonly causes warm or fluctuating temperatures, prolonged cooling, or temperature-related error codes when failing
• Works as a direct-sensing temperature input — not a user control or switch

• One temperature sensor/thermistor (single part as shown)

• Unplug the appliance or switch off power at the breaker before servicing
• Handle the sensor and its thin leads carefully to avoid damage during removal and installation
• Route and secure wiring so it does not contact moving parts or sharp edges

This flow meter measures the volume of water passing through the refrigerator's water dispensing system. It sends signals to the control board to accurately track water usage and control dispenser operation. Replace this part if your water dispenser delivers inconsistent amounts of water, fails to shut off properly, or if the dispenser display shows inaccurate readings.

Excessive frost build-up or cooling issues? This defrost timer cycles your refrigerator between cooling and defrost modes to restore proper operation.

Fix excessive frost buildup in your refrigerator with this mechanical defrost timer. Controls cooling and defrost cycles to maintain efficiency.

Fix a refrigerator that won't cool properly or builds up excessive frost. This defrost timer controls defrost cycles to prevent ice buildup.

Fixes frost buildup and icing in freezers. This defrost heater melts accumulated ice during defrost cycles. Moderate DIY repair with basic tools.

If frost builds up between compartments or temperatures vary, the mullion heater may have failed. Direct-fit part installs in 30-45 minutes.

Fixes ice buildup around water dispenser spout. This throat heater prevents freezing in the dispenser area. Moderate DIY repair, 30-45 minutes.

This is a bimetal thermostat mounted on the ice maker mold that senses temperature to control the ice harvest cycle. It signals the ice maker to begin the harvest and eject ice once the mold reaches the proper temperature. Replace this thermostat if the ice maker stops producing ice, runs continuously without ejecting cubes, or if ice cubes are only partially frozen.

This is a cartridge-style heater embedded in the ice maker mold that warms the mold just enough to release ice cubes during the harvest cycle. It allows the ice to separate cleanly from the mold so it can drop into the ice bin. Replace this heater if the ice maker stops ejecting ice, cubes are incomplete or stuck in the mold, or the ice maker has stopped cycling.

Freezer cold but refrigerator warm? This defrost heater melts frost buildup on the evaporator coil to restore proper airflow and cooling performance.
