This defrost thermostat is the temperature-sensing switch mounted on the freezer evaporator. It controls power to the defrost heater during the cycle to help prevent frost buildup and restore proper airflow and cooling performance.

• Monitors evaporator temperature and opens the heater circuit when the coil warms
• Helps stop heavy frost/ice accumulation on the evaporator and back wall
• Failure can cause poor cooling, weak airflow, or frost-covered coils
• If stuck open, may prevent the defrost heater from energizing at all

• Disconnect power to the refrigerator before service
• Access the evaporator behind the freezer's rear panel; locate the thermostat attached to the coil/tubing
• Install the new thermostat in the same location and orientation, ensuring firm contact with the evaporator surface
• Route and secure wires as original; keep clear of the fan and moving parts

This defrost thermostat monitors the evaporator coil temperature and controls power to the defrost heater. Replacing a failed thermostat restores proper defrosting, reduces frost buildup, and helps keep fresh food and freezer compartments cooling as designed.

• Senses evaporator temperature to open/close the defrost heater circuit at the correct point in the cycle
• Protects against overheating during defrost by interrupting power when the set temperature is reached
• Helps prevent heavy frost/ice accumulation on the evaporator and loss of airflow
• Common signs it may be bad: ice behind the freezer rear panel, warm refrigerator section, unit never defrosts or refreezes soon after a manual defrost

• Disconnect power before servicing; wear cut-resistant gloves
• Remove the freezer's rear panel to access the evaporator; the thermostat is typically clamped to an evaporator tube
• Match wire positions and mount the new thermostat in the same location with firm contact to the tubing
• Route wires away from the fan and sharp edges; reassemble and verify normal defrost operation

Replacement thermostat kit restores accurate temperature sensing so the appliance can maintain correct operating temperatures. Use this kit when a failing thermostat causes inconsistent temps or frequent cycling. What it does:

• Senses internal temperature and signals the control to turn heating or cooling on and off.
• Helps the appliance maintain stable temperatures and proper cycle behavior.
• Commonly replaced for inconsistent temperatures, failure to reach set temperature, or excessive cycling.
• Matches OEM function for direct replacement of the original thermostat kit.

• Disconnect power (unplug or shut off circuit) before starting any repair.
• Follow the appliance's service manual for correct routing and secure mounting of the sensor or capillary.
• Handle the sensor/capillary gently to avoid kinks or damage.

This defrost thermostat senses evaporator temperature to control the defrost heater. Replacing a failed thermostat restores proper defrosting, prevents overheating during the defrost cycle, and helps maintain stable cooling performance.

• Monitors evaporator coil temperature and closes to power the defrost heater during defrost
• Opens the heater circuit as the coil warms to terminate defrost and prevent overheating
• Helps clear frost from the evaporator so air can circulate between freezer and refrigerator
• Failure may present as heavy frost/ice buildup, reduced cooling in the fresh food section, the evaporator fan hitting ice, or a defrost cycle that fails to start

• Disconnect power before servicing; defrost heavy ice as needed for access
• Located on/near the evaporator coil behind the freezer's rear panel, typically clipped to tubing
• Match original clip orientation and wire routing; ensure firm thermal contact with the coil/tube
• After installation, confirm operation with a continuity check at freezer temperature or run a manual defrost test per the service manual

Also called a thermodisc, this evaporator-mounted defrost thermostat monitors coil temperature and switches the heater off when frost is cleared. Replacing a failed thermostat helps restore proper defrosting, airflow, and consistent refrigerator temperatures.

• Senses evaporator coil temperature during the defrost cycle
• Closes when the coil is cold to let the defrost heater energize; opens as the coil warms to stop heating
• Helps prevent heavy frost buildup that restricts airflow and cooling
• Symptoms include ice on the rear freezer panel, poor cooling, or the defrost heater not turning on

• Disconnect power before servicing
• Access from the freezer by removing shelves and the rear panel
• Attach the thermostat securely to the same tubing location for good thermal contact; route wires away from moving parts
• Fully defrost any existing ice before returning the unit to service

This thermostat regulates appliance temperature to help maintain proper heating and cycling for safe, consistent operation. It replaces a failed thermostat to restore correct temperature control and reduce unexpected shutoffs or inconsistent heat. What it does:

• Senses and opens/closes the circuit to control heating elements or compressors
• Can stop heating when the set temperature is reached to prevent overheating
• Commonly used when the appliance won't reach or maintain the correct temperature
• Helps address intermittent heating, continuous running, or overheating symptoms

• Disconnect power before servicing to avoid shock or injury
• Handle thermostat terminals carefully; ensure secure, correct wiring connections

The Wire Harness is an OEM part for Frigidaire refrigerators. It connects various electrical components within the refrigerator, ensuring proper communication and voltage.

A bad wire harness can be caused by wear and tear, damage, or electrical issues. When the harness becomes faulty, it can result in issues such as intermittent or complete loss of power, malfunctioning controls, or improper functioning of the refrigerator's features.

Symptoms of a bad wire harness include:

• Loss of power to the refrigerator or specific components
• Inconsistent or erratic operation of controls or displays
• Malfunctioning lights, fans, or other electrical features

Replace your faulty wire harness with this genuine OEM part to restore your refrigerator. This Frigidaire part can also be used on Electrolux, Frigidaire, Gibson, Kelvinator, Westinghouse, and Sears/Kenmore.

A 2 amp replacement fuse that protects low-current appliance circuits by opening when an overcurrent occurs. Install this direct-replacement fuse to restore power to control circuits and stop damage from a blown fuse. What it does:

• Interrupts current in control or low-voltage circuits when the fuse rating is exceeded
• Prevents electrical damage by opening the circuit on overloads
• Common symptoms of a blown fuse: appliance won't power on, controls are unresponsive, or intermittent operation
• Use as a like-for-like replacement matched to the original 2 amp rating

• Disconnect power to the appliance before inspecting or replacing the fuse
• Replace only when the appliance is cool and dry; avoid touching conductive ends

This thermostat light is the small indicator lamp that illuminates the control area so you can see thermostat settings and status. It provides a clear visual signal when the control is powered. What it does:

• Lights the thermostat/control panel area for visibility
• Indicates when the control or circuit is energized
• Commonly replaces a burned-out or dim lamp
• Helps diagnose a non-illuminated control (lamp failure vs. power issue)

• Disconnect power to the appliance before inspecting or replacing the lamp
• Remove the control panel or housing per the appliance service instructions to access the lamp
• Handle the lamp and connector carefully to avoid damage; do not force wiring
• If the control remains unlit after replacement, test for power to the control
