What are the signs that my HVAC/Furnace control board is faulty?

If you suspect that your HVAC/Furnace control board might be faulty, look for the following signs:

  1. System Won't Turn On: If your HVAC or furnace fails to start, it could be due to a malfunctioning control board.
  2. Blower Running Continuously: A blower that doesn't shut off is a common symptom of control board issues.
  3. Error Codes on Thermostat: Many modern thermostats display error codes when there's a problem with the control board.
  4. Irregular Heating or Cooling Cycles: If your system is not maintaining consistent temperatures or cycles on and off erratically, the control board might be at fault.
  5. Unresponsive Controls: If the thermostat or control panel doesn't respond to inputs, it may indicate a control board problem.
  6. Burnt or Corroded Components: Visual inspection might reveal burnt or corroded areas on the control board, indicating damage.
  7. No Power to System Components: If certain components of your HVAC/Furnace system aren't receiving power, the control board could be the culprit.
