Refrigerator Not Cooling? Inverter Board W11567409 – Fix Compressor Failure Fast

A failed inverter board is one of the most common reasons a Whirlpool-built refrigerator stops cooling entirely. In most Whirlpool, Maytag, KitchenAid, Amana, and JennAir refrigerators with inverter compressors, this board is the first component to fail when the compressor stops running. When it fails, the compressor receives no control signal — the fridge warms up, the freezer thaws, and no amount of thermostat adjustment will restore cooling. ⚡ Common failure point in Whirlpool-platform inverter-compressor refrigerators. Part W11567409 is the genuine OEM replacement that restores full compressor control and brings your refrigerator back to factory cooling performance.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Your refrigerator powers on — lights, display, and fans work normally
• ✔ The evaporator fan runs but the compressor does not start (or starts briefly then shuts off)
• ✔ You have confirmed the outlet and power supply are functioning correctly
• ✔ The ONLY problem is the compressor not running / refrigerator not cooling

🔧 Common Symptoms

• Refrigerator not cooling — fresh food and freezer warming up
• Compressor hums briefly then clicks off (short-cycling)
• Compressor completely silent — no vibration or heat at the back of the unit
• Error codes on display: E0, E1, CF, or compressor communication fault
• Clicking or buzzing from the rear bottom of the refrigerator
• Fans running normally but no cooling produced

✔ If these symptoms match, the inverter board is the most likely failed component in the system.

✔ In most cases, replacing this inverter board restores normal compressor operation immediately after installation.

⚙️ Installation

Skill Level: Moderate — 30 to 60 minutes. Disconnect power before servicing. Pull the refrigerator away from the wall and remove the rear lower access panel. Disconnect the wire harness connectors from the old inverter board, unscrew the mounting hardware, swap in the new board, reconnect all harnesses, and restore power. No programming required — the board communicates with the main control board automatically on first power-up.
