International Comfort Products GPFM42K100F Control Board
The International Comfort Products GPFM42K100F control board is constructed to command everything including the gas valve, the ignition igniter, all the various sensors as well as the air circulator all in one unit. It is impossible for your furnace or air handler to even run without the control board configured and seated properly. Be very careful while picking a new replacement board because of the wide variety of brand and air handler types. The board that you will choose will have to be compatible with both the make and model of the system you have installed.
What are the indications that my primary control board is about to stop working?
- The entire system has to be turned off and back on repeatedly for it to work
- System is unable to do anything whatsoever
- There seems to be some sort of code indicated on the circuit board
