⚠️ Refrigerator Not Cooling or Compressor Won’t Start? W10629033 Is the Fix.

The inverter board controls your refrigerator’s variable-speed compressor. When it fails, the compressor can’t run — and your fridge stops cooling entirely. Part W10629033 is the genuine OEM inverter board for Whirlpool refrigerators, superseding W10133449, 2209324, 8201670, and a full range of earlier part numbers. Available as a factory-new OEM unit or a tested used pull.

The inverter board sits in the compressor compartment at the rear base of the refrigerator. It converts incoming AC power to variable-frequency DC to drive the inverter compressor motor at the correct speed. If your compressor hums but won’t start, runs constantly without cooling, or throws inverter-related error codes, this board is the primary suspect. Confirm your model number before ordering — inverter boards are model-specific.

• Refrigerator not cooling or freezing at all
• Compressor hums briefly then shuts off without starting
• Fridge runs constantly but never reaches set temperature
• Intermittent cooling — works for a while then stops
• Error codes related to compressor, inverter, or sealed system
• Excessive energy consumption with poor cooling output
• Compressor compartment very hot to the touch

Skill Level: Intermediate–Advanced. Disconnect power before beginning — this board carries line voltage. The inverter board is located in the compressor compartment at the rear base of the unit; remove the access panel to expose it. Photograph all wire harness connections before disconnecting. The board is static-sensitive — handle carefully and avoid touching circuit traces. Reconnect all harnesses firmly, restore power, and verify the compressor starts and cooling resumes before replacing the access panel.

Verify your full model number before ordering. Inverter boards are model-specific — an incorrect board will not communicate properly with your compressor.
