Friedrich VHA18K Control Board
The entire heating and cooling system will not run at all lest this board is in connected and operational. The control board is constructed to command everything including the gas valve, the igniter, all the sensors as well as the blower all in one unit. The correct control board will need to be a match with your existing board and be compatible with the brand and the model of the unit in question. It is of utmost importance when you are deciding on a replacement due to differences in models within certain brands.
Simple signals your control board is going out
- System has a strange code shown directly somewhere on the circuit board
- The control board needs to be reset all the time for it to kick in
- AC or heating system does not do anything whatsoever
