Refrigerator Manual Defrost Parts

The Heater is an OEM component specifically designed for Whirlpool bottom-mount refrigerators. Located within the fresh food compartment walls, it prevents condensation by maintaining warm air circulation along interior surfaces. 

Causes of a bad heater include deterioration of heating coils or electronic boards over many years, loose connections disrupting power delivery, or damage from moisture exposure.

Symptoms include:

• Foggy or frosted exterior walls need frequent drying  
• Puddles of water collecting beneath vegetable drawers
• Musty odors developing within refrigerator shelves

This OEM replacement is also compatible with Kenmore, KitchenAid, and some GE models.

This freezer thermistor is the sensor that reports compartment temperature to the control system. Replacing a faulty sensor restores accurate temperature feedback and normal cycling so the freezer maintains consistent, food-safe temperatures.

• Monitors freezer temperature and sends a resistance signal to the control
• Helps regulate compressor and evaporator fan operation for stable cooling
• Failure can cause temperatures that are too warm or too cold
• May lead to long run times, short cycling, or erratic temperature displays/alarms

• Disconnect power before servicing
• Access the sensor in the freezer and note its original routing and position
• Install the new sensor in the same location; route wires along the factory path and ensure a secure connection
• Restore power and allow up to 24 hours for temperatures to stabilize

The defrost heater warms the evaporator during automatic defrost to melt frost so air can circulate freely. Replacing a failed heater helps stop heavy ice buildup, restore cooling performance, and prevent fan noise from ice contact.

• Clears frost from the evaporator so cold air can move between compartments
• Helps maintain stable temperatures and efficient cooling
• Common symptoms of a failed heater: thick frost on the back freezer panel, poor cooling, or fan scraping ice
• Electric resistance element that often tests open (no continuity) when failed

• Disconnect power before servicing; do not work on a live appliance
• Remove freezer shelves/drawers and the rear panel to access the evaporator and heater
• Allow ice to thaw; handle fins and tubing carefully to avoid damage
• Route wiring and clips as originally installed and ensure tight electrical connections before reassembly

This replacement temperature sensor measures the compartment temperature and reports it to the control board, helping your refrigerator maintain consistent cooling. Replace a failing sensor to restore accurate temperature readings and dependable performance.

• Monitors refrigerator/freezer temperature and relays data to the control
• Helps the system regulate compressor and fan operation for steady cooling
• A failing sensor can cause temperatures that are too warm or too cold
• May lead to extended run times, short cycling, or erratic cooling

• Disconnect power before servicing; wear cut-resistant gloves.
• Location varies by model; commonly clipped to the evaporator or mounted in an air duct/liner.
• Match the connector, route wiring along the factory path, and secure the probe in its original position.
• Restore power and allow up to 24 hours for temperatures to stabilize.

• Access the heater behind the freezer's rear panel; it mounts at/under the evaporator
• Note wire routing and clip locations; transfer any reusable hardware from the original part
• Avoid bending the element or damaging evaporator fins; fully defrost ice before reassembly

This defrost thermostat senses the evaporator coil temperature and controls the defrost heater. Replacing a failed thermostat restores proper defrosting to prevent heavy frost buildup and helps your refrigerator keep consistent, reliable cooling.

• Monitors evaporator temperature to allow the defrost heater to energize and to terminate the cycle as the coil warms
• Protects against overheating in the evaporator area during defrost
• Failure symptoms include frost/ice buildup on the evaporator cover, reduced airflow, fresh food section warming, or the unit not defrosting
• Typically mounts clipped to the evaporator tubing inside the freezer

• Disconnect power before servicing and remove the freezer's rear panel to access the evaporator
• Transfer the clip/bracket if present and mount the new thermostat in the same location, ensuring firm metal-to-metal contact with the evaporator tubing
• Route wires away from the heater and moving parts; secure connections and reassemble panels before restoring power
• Wear cut-resistant gloves—sheet-metal edges can be sharp

This defrost heater assembly melts frost from the evaporator during the defrost cycle to keep air flowing and maintain consistent temperatures. Replacing a failed heater helps restore proper cooling performance and prevents excessive frost buildup.
