White Westinghouse Refrigerator Control Board

The Defrost Control Board is an OEM part for Frigidaire refrigerators. This board manages the defrost cycle by controlling the activation of the defrost heater and the monitoring of the freezer's temperature. 

Over time, the defrost control board can fail due to electrical issues, wear from continuous use, or damage from power surges. 

Symptoms of a bad defrost control board include:

• Excessive frost buildup in the freezer compartment
• The refrigerator not cooling properly
• The defrost heater not activating
• Frequent cycling on and off of the refrigerator

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

This is a refrigerator control board. The function of the control board is to effectively control all of the refrigerator's functions. These functions could include cooling the fridge, defrosting, dispensing, and even lighting.In the event that any of the functions of the refrigerator stop working correctly, the control board could be the culprit. If the buttons on the unit are pressed and nothing happens, it's likely that the control board is faulty. For example, the refrigerator may not be cooling, defrosting, the lights might not work, or the ice and water will not dispense. If this is the case, this is a high-quality replacement part. Make sure to unplug the refrigerator from the electrical outlet before replacing this part. This specific control board is compatible with refrigerators that are manufactured by the Frigidaire and Crosley brands. It is sold individually and sourced straight from the manufacturer.

This replacement board-switch is the electronic control that manages user inputs and basic appliance functions, restoring reliable response from the control panel. Use it to replace a faulty board causing unresponsive or erratic controls. What it does:

• Routes user inputs to the appliance's control system so buttons, knobs or touchpads register correctly.
• Activates internal relays/outputs that initiate functions; failure can cause controls to be unresponsive or commands not to execute.
• Helps stop intermittent or erratic behavior caused by a damaged or corroded control board.
• Resolves symptoms such as non-working control buttons, blank or flickering display, or inconsistent function selection.

• Always disconnect power at the breaker or unplug the appliance before starting work to avoid shock.
• Handle the board by its edges and avoid touching components; use an anti-static strap if available.
• Keep track of screws and wire connections; label or photograph harness locations before removal for correct reassembly.

This power control board is the refrigerator's main electronic control that manages power distribution and system functions so the appliance runs reliably and responds to user settings. What it does:

• Supplies and regulates power to compressor, fans, lights and other subsystems
• Processes input from the user interface and sensors to control cooling cycles
• Helps protect against erratic operation by coordinating start/stop functions
• Common symptom fixes: unit won't power on, intermittent operation, lights or fans not running, or failure to start cooling

• Disconnect all power to the appliance before starting work
• Handle the board by its edges and avoid static discharge; wear an anti-static wrist strap if available
• Verify connector alignment and seating; do not force pins or connectors
