Refrigerator Not Cooling Correctly? Control Box Assembly W11353813 – Fix Temperature Control Fast

If your Whirlpool refrigerator is running warm, cycling erratically, or failing to maintain set temperatures, the control box assembly is one of the most common root causes. In WRT-series Whirlpool top-freezer refrigerators, this assembly houses the main control electronics that regulate compressor cycling, fan operation, and temperature sensing. When it fails, the refrigerator may run constantly, not run at all, or lose the ability to hold a stable temperature in either compartment. ⚡ Common failure point in Whirlpool WRT108, WRT318, WRT519, and WRT549 series refrigerators. Part W11353813 is the genuine OEM replacement that restores precise temperature control and normal compressor cycling immediately.

❓ Is This the Right Part?

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

• ✔ Refrigerator powers on — lights work and compressor attempts to run
• ✔ Door seals are intact and condenser coils have been cleaned
• ✔ Temperature sensor/thermistor has been tested and is within spec
• ✔ ONLY problem is inconsistent cooling, erratic cycling, or complete loss of temperature control

🔧 Common Symptoms

• Refrigerator runs constantly but never reaches set temperature — most common complaint
• Refrigerator stops cooling entirely — compressor not cycling on
• Freezer section freezes correctly but fresh food compartment is warm
• Temperature fluctuates widely between cycles
• Compressor short-cycles — turns on and off rapidly without completing a full cooling cycle
• Control panel unresponsive or displaying incorrect temperature readings

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

✔ In most cases, replacing this control box assembly restores normal refrigerator operation immediately.

⚙️ Installation

Skill Level: Moderate — 20 to 35 minutes. Unplug the refrigerator before servicing. The control box is typically located in the upper interior of the fresh food compartment behind a cover panel — remove the panel screws, disconnect the wiring harness connectors, swap the assembly, and reconnect. Take a photo of the harness layout before disconnecting to ensure correct reassembly.
