Heat Controller B-VMH18FC-1 Control Board
The Heat Controller B-VMH18FC-1 control board is made to operate the gas valve, the ignition igniter, most sensors and the blower all together. Your system definitely will not function unless the control board is installed. The control board picked should have part numbers that match both the brand and model of furnace or air handler you have. You should always be careful when choosing a control board due to differences in HVAC systems.
Red flags your Heat Controller control board is not going to last much longer
- AC or heating system is unwilling to function whatsoever
- There may be flashing code instantly appearing somewhere on the circuit board
- The control board has to be powered down and back up quite frequently for the heating or cooling to kick in
