International Comfort Products GPFM48L080F Control Board
The entire heating and cooling system will not operate whatsoever lest the circuit board is in connected and operational. The control board is made to oversee everything including the gas valve, the ignition igniter, all the sensors as well as the blower all in one unit. You must be careful when you are deciding on a replacement due to variances between systems. The board you choose should match the model number with both the brand and specific model of the unit in question.
Indications of a poorly working main board
- The entire system has to be turned off and back on many times a week for the furnace or AC to kick on
- Your system cannot initialize period
- There seems to be some sort of code indicated on the control board
