This defrost thermostat monitors evaporator temperature and controls power to the defrost heater, shutting it off at the correct point in the cycle. Replacing a failed thermostat helps clear frost and restore stable cooling and airflow.

• Senses evaporator coil temperature in the freezer
• Closes when cold to allow the defrost heater to run; opens as the coil warms to terminate defrost
• Helps prevent excessive frost buildup and maintains proper airflow
• Typical failure signs: heavy frost on the evaporator/back wall, weak airflow, warm fresh-food section, unit runs constantly or never defrosts

• Disconnect power and wear appropriate safety gloves before servicing
• Access the evaporator behind the rear freezer panel; note wire routing and original mounting on the refrigerant tubing
• Install the new thermostat in the same location with firm thermal contact; do not damage coil fins or tubing
• If your model uses spliced leads, use approved connectors and secure all joints; replace all covers before restoring power

This defrost heater warms the evaporator coils during the automatic defrost cycle to melt frost and keep air moving. When it fails, ice builds up, airflow drops, and temperatures rise in the fresh food compartment.

• Heats the evaporator to clear frost/ice so the fan can circulate air
• Helps maintain stable temperatures and normal airflow between freezer and refrigerator sections
• Common signs of failure: heavy frost on the back freezer panel, warm refrigerator/cool freezer, fan noise from ice contact, long run times
• Works with the defrost thermostat and control to complete defrost cycles

• Unplug the refrigerator before service; use caution around sharp evaporator fins
• Access the evaporator behind the freezer's rear panel and fully defrost ice before replacement
• Route wiring exactly as original; avoid kinking or stressing the heating element
• After reassembly, restore power and verify a successful defrost cycle per service procedures

This defrost heater melts frost and ice buildup on the evaporator so the freezer can maintain proper airflow and cooling. Replacing a failed heater helps reduce excessive icing and restores normal cooling performance. What it does:

• Heats the evaporator coil during the defrost cycle to remove frost and ice buildup.
• Restores airflow and cooling efficiency when frost accumulation is preventing proper cooling.
• Common symptom link: heavy frost or visible ice on evaporator coils.
• Common symptom link: freezer running continuously or temperatures that are warmer than expected.

• Disconnect power to the appliance before starting any repair.
• Access the evaporator by removing the freezer rear panel; avoid sharp sheet-metal edges.
• Inspect mounting clips and wiring; replace only if damaged and reconnect all terminals securely.
• Test the heater for electrical continuity with a multimeter before and after installation; restore power and confirm the defrost cycle operates normally.

This temperature sensor is the thermistor that monitors compartment temperature and reports it to the control. Replacing a failed sensor helps restore accurate cooling and steady, reliable temperatures in your refrigerator.

• Detects refrigerator or freezer air temperature and sends a resistance signal to the control board
• Helps the control regulate compressor, evaporator fan, and air damper operation
• Also called a thermistor; critical for maintaining stable, set-point temperatures
• Failure symptoms can include sections that are too warm or too cold, erratic temperature swings, or frequent cycling

• Unplug the refrigerator before servicing
• Access location varies by model (often behind an interior cover or air duct); note routing and placement before removal
• Reinstall in the original position and route wiring in the factory path; ensure the connector is fully seated
• Restore power and allow up to 24 hours for temperatures to stabilize

This radiant defrost heater melts ice build-up on the evaporator coil so your refrigerator can maintain proper airflow and cooling. It restores normal defrost operation and helps prevent excessive frost accumulation. What it does:

• Radiant heating element designed to melt frost and ice from the evaporator coil during the defrost cycle
• Restores airflow and consistent cooling when the evaporator has been restricted by ice
• Common symptom: visible frost or ice on evaporator or in freezer compartment
• Common symptom: poor or uneven cooling, longer run times, or a freezer that cycles abnormally

• One radiant defrost heater (single unit as shown)

• Disconnect power to the appliance before servicing to avoid shock risk
• Access typically requires removing the evaporator cover; handle evaporator fins and heater carefully
• Inspect defrost thermostat/thermistor and defrost control components while replacing the heater — replace only the failed components

This fill tube heater keeps the ice maker's water inlet from freezing so your refrigerator can produce ice reliably. It applies gentle heat around the fill tube to help prevent ice blockages and water drips in the freezer.

• Warms the ice maker fill tube to help prevent freezing and ice buildup
• Helps maintain consistent water flow into the ice maker during fill
• Can address symptoms like no ice production, small/hollow cubes, or a frozen fill tube
• Reduces leaks at the fill spout caused by ice blockage

• Unplug the refrigerator and turn off the water supply before servicing.
• Defrost any ice in the fill tube area; avoid sharp tools that can puncture plastic.
• Route and secure the heater along the fill tube as originally installed; avoid pinching wires.
• Ensure the electrical connector is fully seated, then restore power and verify ice maker operation.

This thermodisc temperature switch senses refrigerator evaporator temperature and helps control defrost and cooling cycles to prevent overcooling or prolonged defrost runs. It's a compact replacement part for temperature regulation systems. What it does:

• Opens or closes an electrical circuit based on temperature to signal defrost or compressor control
• Helps stop defrost heater when the evaporator reaches target temperature
• Can prevent extended cooling cycles when the sensed temperature indicates the system has reached desired cold
• Restores normal cycling when a failed thermostat causes continuous run or no cooling

• Disconnect power before servicing to avoid shock or injury
• Confirm location and orientation with the appliance wiring diagram before removal
• Handle the sensor element carefully; avoid bending or damaging the capillary/sensing tip
• After installation, observe normal defrost and cooling cycles

This kit restores your refrigerator's automatic defrost, melting frost from the evaporator so airflow and temperatures stay consistent. Use it when frost builds up and cooling performance drops in the fresh food section. What it does:

• Heats the evaporator coil during the defrost cycle to melt frost and ice
• Bimetal thermostat opens to end defrost at the correct temperature, preventing overheating
• Helps maintain proper airflow between freezer and refrigerator compartments
• Common signs include heavy frost on the back freezer wall, warm refrigerator section, or long run times with poor cooling

• 1 defrost heater and 1 defrost termination thermostat

• Unplug the appliance before service; wear cut-resistant gloves—edges can be sharp
• Remove freezer shelves/bin and rear panel to access the evaporator; photograph wiring for reference
• Clip the new thermostat to the same tubing location/orientation as the original and ensure firm contact
• Route wiring like the original, avoid damaging fins, reinstall the rear cover for proper airflow, and allow up to 24 hours for temps to stabilize
