Friedrich P-09 Control Board
The control board is created to control everything including the gas valve, the igniter, most sensors as well as the blower all at once. It is impossible for your furnace or air handler to even run without the board installed. You must be sure while picking a new replacement board due to variances between models and types. A replacement board will have a matching part number that will fit in both the brand and specific model of your particular system.
Symptoms your primary control board will need replacing
- Air conditioner or furnace is unwilling to operate at all
- There is numbered code shown on the circuit board
- The system has to be turned off and back on habitually for the thermostat to kick in
