Refrigerator Not Cooling – Fix a Failed Compressor Fast

In Whirlpool, KitchenAid, and Maytag French door and bottom-freezer refrigerators, a failed compressor is the most common cause of complete cooling loss. When the compressor fails, the refrigerant circuit stops pressurizing — the fridge section warms up, the freezer stops freezing, and the unit may click on and off repeatedly or go completely silent. ⚡ Left unrepaired, food spoilage begins within hours. Part W11370574 is the genuine OEM replacement compressor kit that restores full refrigeration immediately upon correct installation.

❓ Is This the Right Part?

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

• ✔ Your refrigerator is a Whirlpool, KitchenAid, or Maytag French door or bottom-freezer model
• ✔ Your model number appears in the supported models list below
• ✔ The fridge and freezer are both warm despite the unit running (or attempting to run)
• ✔ You have confirmed the start relay, evaporator fan, and condenser fan are functioning
• ✔ ONLY problem is the compressor failing to pressurize the refrigerant circuit

🔧 Common Symptoms

• Refrigerator not cooling — fridge section at room temperature
• Freezer not freezing — ice melting, food thawing
• Compressor clicks on and off repeatedly (thermal overload tripping)
• Compressor runs constantly but fridge stays warm
• Compressor won't start — unit is silent from the back
• Loud clicking or buzzing from the rear of the refrigerator

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

✔ In most cases, replacing this compressor kit restores normal cooling operation immediately.

⚙️ Installation Notes

Skill Level: Professional — EPA Section 608 Certification Required. Disconnect power before beginning any work. Recover all refrigerant using certified equipment before disconnecting the old compressor. Install the new compressor using the required fittings (SAV4, W11504415, W11504431, W11506619) to ensure sealed refrigerant connections. Recharge with the correct refrigerant type and quantity per the unit's data plate. Leak-test all connections before returning the refrigerator to service.
