Troubleshoot an HVAC Control Board
Your control board manages the sequence of operations that defines your furnace’s functionality. A disturbance in this sequence, or operations that appear out of order, usually reveal problems with the control board. If you’ve had problems with your furnace, pay attention to its operation sequence to judge whether a faulty control board exists as the cause of your troubles.
- The call for heat starts the induced draft motor in furnaces that have one.
- The inducer closes a pressure switch to either ignite your pilot, start the direct spark igniter, or warm up the hot surface igniter.
- The gas valve energizes to light the burners.
- A timer begins for the energizing of the furnace blower.
- The furnace blows until the set temperature is achieved.
- The controller shuts off the gas.
- A timer regulates the shut-off of the furnace fan.
A little foreknowledge of furnace operation can combine with observation of this sequence to determine the functionality of your control board. If any of these operations fail to occur, or seem to occur out of order, you can place the blame on your control board.
