Refrigerator Control Board Troubleshooting

Keeping Your Cool Effortlessly with FairApplianceRepair

10 minute read

Is your refrigerator not cooling properly, or are you facing issues with its defrosting cycle? Often, these problems point towards a malfunctioning control board, which acts as the brain of your refrigerator. Understanding how to troubleshoot this critical component can save you time and ensure your fridge runs smoothly.

What is a Refrigerator Control Board?

The control board in a refrigerator is akin to a mini-computer. It’s a printed circuit board housing various electrical components like semiconductors, resistors, and capacitors. This board controls vital functions of your fridge, including the compressor, fans, and motors. When it fails, you might notice issues with cooling, defrosting, or even the ice maker and water dispenser.

Symptoms of a Bad Control Board

A problematic control board can manifest in several ways:

  • Inconsistent cooling or over-freezing
  • Issues with the ice maker and water dispenser
  • Abnormal operation of the compressor and fan motors

In some models, like Whirlpool refrigerators, error codes displayed in diagnostic mode can be a tell-tale sign of control board issues. These codes can guide you towards specific problems and are a good starting point for troubleshooting.

This Whirlpool fridge stopped working. We made a diagnostic and found defrost system didn’t work properly and the reason for that was an issue with the main control board. We brought a new one and replaced it so now the fridge is working properly again. Music: Summer Bells, Musician: View Points, Album: View Points, Source: https://www.vcg.com/

DIY Troubleshooting Steps

Before you consider replacing the control board, which can be an expensive affair, try these steps:

Look for Error Codes: If your refrigerator displays error codes, refer to the user manual to understand what they indicate.

Reset the Control Board: Sometimes, a simple reset can solve minor glitches. Disconnect the fridge from power for about ten minutes and then reconnect it.

Inspect Visually: Check the board for any signs of damage, such as burnt areas or a distinct smell of burning electronics.
