Refrigerator Not Cooling? Main Control Board 5304535442 – Fix No-Cool & Compressor Faults Fast

If your Frigidaire or Electrolux refrigerator has stopped cooling, runs constantly, or won't start the compressor, the main control board is the most common cause. In most Frigidaire-built refrigerators, the main control board governs compressor operation, fan motor sequencing, defrost cycles, and temperature regulation. When it fails, the refrigerator may stop cooling entirely, cycle erratically, or display fault codes. ⚡ Common failure point in Frigidaire and Electrolux refrigerators built after 2015. Part 5304535442 is the genuine OEM replacement that restores full electronic control and normal refrigeration operation.

❓ Is This the Right Part?

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

• ✔ Refrigerator powers on — display lights up or interior light works
• ✔ Evaporator fan and condenser fan run (or ran) at some point
• ✔ Power supply to the unit is confirmed OK — outlet and cord are fine
• ✔ Start relay and compressor have been tested and are not the root cause
• ✔ ONLY problem is loss of cooling, compressor not starting, or erratic temperature control

🔧 Common Symptoms

• Refrigerator not cooling or freezer not freezing — most common complaint
• Compressor won't start or runs continuously without cycling off
• Temperature fluctuates or won't hold set point
• Fans run but no cooling — compressor never kicks on
• Error codes SY EF, SY CF, or H1 displayed on control panel
• Refrigerator completely dead after power surge or outage

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

✔ In most cases, replacing this control board restores normal compressor cycling and cooling immediately.

⚙️ Installation

Skill Level: MODERATE — 30–45 minutes. Unplug the refrigerator before beginning any work. The control board is typically located at the rear of the unit behind a panel; remove the panel screws, disconnect the wire harness connectors (photograph before disconnecting), swap the board, and reconnect in reverse order. Handle the PCB by its edges only — avoid touching solder points or components.
