Customer Questions and Answers for Inverter (Compressor Drive Board) by Whirlpool

This inverter converts the refrigerator's incoming power and controls compressor speed so the cooling system runs efficiently. Replacing a failed inverter restores proper compressor operation and helps return normal cooling performance. What it does

• Converts incoming AC power to the DC signals the variable-speed compressor needs
• Regulates compressor speed for temperature control and energy-efficient operation
• Works with the fridge's main control systems to manage compressor operation

• Disconnect power to the appliance before beginning any service to avoid shock
• Handle the board by its edges and avoid touching components; observe ESD precautions
• Mount and connect using original-style fasteners and harness connectors; verify secure, corrosion-free connections
• Check compressor, main control board, and harness for related issues if symptoms persist after replacement.
