Whirlpool Refrigerator Control Box Assembly W11629179 — Fixes Refrigerator Not Cooling / Restores Temperature Control
🇺🇸 Matching U.S. Part Number: W11629179
W11629179 is a genuine Whirlpool refrigerator control-box assembly used on refrigerator model WSR57R18DM06. It replaces discontinued OEM number W11555882.
The control box receives temperature and control inputs and coordinates applicable cooling functions. A defective control may contribute to incorrect temperatures, failure to start or cooling components not operating as commanded.
Similar symptoms can also result from the compressor system, thermistor, wiring, fan, start components, power supply or another part. Confirm the complete refrigerator model and diagnose the applicable circuit before ordering.
Disconnect electrical power before servicing. Handle electronic components using appropriate static-control precautions.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Refrigerator powers on and displays normally
- ✔ Fan motors and compressor have been tested and confirmed functional
- ✔ Power supply and wiring harness confirmed OK
- ✔ ONLY problem is incorrect temperature, failure to cool, or cooling components not responding to control commands
The control box is one possible cause; cooling and starting symptoms require model-specific diagnosis. Not sure? Send us your model number — we’ll confirm before you order.
🔧 Common Symptoms
- Refrigerator not cooling or unable to maintain set temperature
- Compressor not running or short-cycling
- Refrigerator won’t power on or start
- Erratic or unresponsive temperature controls
- Fan running but no cooling
- Cooling components not responding to control commands
A failed control box is one possible cause of these symptoms. May restore normal control operation when diagnosis confirms that the original control box is defective.

Before replacing the control box assembly, test the compressor start relay — shake it and listen for a rattle, which indicates failure. A faulty relay mimics a dead control board. Replacing both in the same service call eliminates the two most common root causes and avoids a second labour visit.
⚙️ Installation
Skill Level: Moderate — intermediate appliance repair experience recommended. Disconnect power before beginning any repair. Photograph all wire harness connections before disconnecting. Transfer all connectors to the new assembly in the same positions, restore power, and verify temperature settings after installation. Allow 24 hours for the refrigerator to reach full operating temperature before further troubleshooting.

💡 Pro Tip
