Parts for Frigidaire FFU21M7HWP: 07 - System Parts

This main wiring harness routes power and signals between a refrigerator's control board and its components so the appliance can run its compressor, fans, lights and defrost system reliably. What it does:

• Distributes electrical power and control signals to compressor, evaporator and condenser fans, interior lights and defrost/heater circuits
• Restores power routing when a damaged harness causes intermittent or complete loss of function
• Can resolve symptoms such as no lights, no compressor or fan operation, intermittent power to components, or defrost/ice-maker failures
• Connects directly to the appliance's control board and component plugs to maintain factory wiring organization

• Always disconnect power to the appliance before starting work to avoid shock or short circuits
• Take photos or label connectors before removing the old harness to ensure correct reassembly
• Route the new harness along factory clips and channels; avoid pinching or sharp edges that can chafe wires
• Ensure all connector pins are fully seated and secure; test appliance functions after restoring power

The Support is an OEM part for Frigidaire refrigerators. This component is designed to provide structural stability and support within the refrigerator, ensuring that various internal parts remain securely in place during operation.

Over time, the support can wear out or become damaged due to regular use, heavy loads, or accidental impacts. Issues such as the refrigerator shelves not staying in place, unusual noises during operation, or visible damage to the support structure are signs that a replacement may be necessary.

Symptoms of a bad support include:

• Shelves not staying in place
• Unusual noises during operation
• Visible damage to the support structure

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.

The Support-Shelf is an OEM part for Frigidaire freezers, designed to provide sturdy and reliable support for the freezer shelves. This part ensures that the shelves remain level and secure under the weight of stored items.

Causes of a bad Support-Shelf can range from overloading shelves beyond their weight capacity, to normal wear and tear from years of use. 

Symptoms of a bad Support-Shelf include:

• Shelves sagging or not sitting level, which can lead to inefficient storage and the risk of items falling.
• Cracks or breaks in the support, compromising the stability of the entire shelving system.
• Difficulty installing or removing shelves, indicating that the supports may be damaged or misshapen.

This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.

This compressor kit is made to be used with freezers and refrigerators by several manufacturers. It includes the compressor as well as all small parts associated with it. The compressor is a component that helps move the refrigerant throughout the appliance's system. Temperature sensors indicate when the compressor should run. If the compressor is damaged, it may make strange noises, no longer cool properly, or could begin to overheat.If any of these issues are present, the compressor should be replaced. First, make sure the refrigerator is not connected to a power source. Remove perishable items from the appliance and place them in an icebox, cooler with ice, or another refrigerator. Locate the compressor on the back of the appliance by removing the metal guard. Remove the wire between the compressor and the capacitor before taking off the compressor. Replace this part with the new one by connecting it to the wire and reassembling the appliance.This is a compressor kit for use with refrigerators and freezers made by Crosley, Electrolux, Westinghouse, Frigidaire, Kelvinator, Tappan, and Gibson. It is sourced directly from the manufacturer and sold as a single part. This is a genuine OEM replacement part.

This controller is the appliance's electronic control board. It manages key cooling functions and restores normal operation when the original board fails, helping the unit maintain stable performance and temperature. What it does

• Directs power to compressor and fan motors to regulate cooling cycles
• Interprets inputs from sensors/controls to maintain target temperature
• Coordinates system operations for consistent performance
• Common failure symptoms include no cooling, intermittent cooling, constant running, or unresponsive controls

• 1 controller

• Disconnect power before servicing; observe ESD precautions when handling the board
• Photograph wiring and note connector orientation before removal
• Mount the new board securely and reconnect all harnesses fully seated
• Restore power and monitor operation; allow time for temperatures to stabilize

This small mounting clip secures interior or cabinet components to keep panels and trim stable, helping reduce noise and maintain proper alignment. It's a simple replacement that restores a snug fit where the original clip has broken or worn. What it does:

• Holds panels, trim, or small components in place to prevent gaps or rattling
• Restores proper alignment of clipped parts after damage or wear
• Maintains a secure attachment point for adjacent parts during normal use
• Helps prevent moisture or debris from entering behind secured panels

• Disconnect power or unplug the appliance before accessing internal components
• Handle the clip and surrounding trim carefully to avoid cracking adjacent plastic
• Use basic hand tools as needed; do not force clips into place—align before snapping
• Replace any damaged mounting features for a secure fit

The Run Capacitor is an OEM replacement part for Frigidaire refrigerators. This electrical component plays a crucial role in providing the initial torque needed to start and run the compressor motor, ensuring efficient and reliable operation of your refrigerator's cooling system.

Causes of needing to replace the run capacitor can include normal wear and tear over time, exposure to high temperatures or electrical surges, or physical damage to the capacitor itself.

Symptoms that may indicate a failing run capacitor include:

• The refrigerator not running or cooling properly
• The compressor failing to start or running intermittently
• Humming or buzzing noises coming from the compressor area

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore refrigerator models. 

This replacement power cord delivers household electricity from the outlet to your appliance. Installing a new cord restores safe, reliable power when the original is damaged, worn, or causing intermittent operation.

• Supplies AC power from a household outlet to the unit
• Common fix for no power, flickering lights, or power loss when the cord is moved
• Replaces cords with cuts, cracks, burn marks, or melted areas
• Restores a secure electrical connection for safe, consistent operation

• Unplug the appliance and verify the wall outlet is working before replacing parts
• Access the cord routing and internal connections; note wire positions and routing before removal
• Transfer and secure any strain relief/clamp; keep wiring clear of sharp edges and hot surfaces
• After installation, ensure the cord isn't pinched and the plug seats fully in the outlet
