Time to Change Your HVAC Control Board

Acting as the brain of your heating or cooling system, the HVAC control board is pretty crucial for your comfort at home. The control panel (or board) has a number of responsibilities, including turning your system on and off, processing system commands and alerting you to system issues. Because the entire system relies on the control board, when it malfunctions, your entire HVAC system will shut down.

Changing your HVAC Control Board: The Process

Why do control panels malfunction? There are a couple of reasons. A malfunction in the control panel could be a result of faulty wiring, a loss of electrical power to the system, or a burnout of the control board itself. If your HVAC system is unexpectedly not working properly (you notice things like poor airflow or inconsistent temperatures), check the control board. When the board malfunctions, you’ll see the panel light up with LED lights, or you might find burnt spots on the board. These are signs that it’s time for a replacement.

Signs it’s time for a new HVAC control board

If your HVAC control board malfunctions, you’ll see a few telltale signs that it’s time for replacement. Look out for these changes:

  • Error codes that don’t relate to what the system is doing

  • Intermittent system operation

  • Circuit breaker trips or low voltage fuses fail
