Top Signs Your Appliance Needs a New Control Board

When your appliance starts acting up, it’s not always easy to pinpoint the problem. The control board, often referred to as the "brain" of your appliance, is a common culprit for many malfunctions. At Appliance Pro USA, we specialize in high-quality refurbished control boards to help you fix your appliances affordably and effectively. Here are the top signs that it may be time to replace your control board.


What Does a Control Board Do?

The control board is the electronic component responsible for managing the essential functions of your appliance, including:

  • Powering the motor and heating elements.
  • Regulating temperature and timing.
  • Communicating with sensors and displays.

When the control board malfunctions, these functions can fail or become erratic, leading to noticeable issues.

  • Possible Cause: The control board may have stopped sending power to the appliance’s key components.

2. Error Codes or Flashing Lights

  • Symptom: The control panel displays error codes or blinking lights.
  • Possible Cause: These codes often indicate a failure in the control board or its communication with other parts.

3. Unusual Sounds

  • Symptom: Buzzing, clicking, or popping noises coming from the appliance.
  • Possible Cause: Electrical issues within the control board’s circuits.

4. Inconsistent Performance

6. Unresponsive Controls

What Causes Control Boards to Fail?

Several factors can lead to control board failure, including:

  • Manufacturing defects.

Regular maintenance and avoiding electrical overloads can help prolong the life of your control board.
