Nordyne FG7SK Control Board
The entire heating and cooling system will not run unless this important circuit board is configured and seated properly. The control board is constructed to operate everything including the gas valve, the ignition igniter, all the sensors as well as the blower all in one unit. Be very careful while picking a new replacement board due to the many differences between models within certain brands. The control board picked should match the brand and the model of your Nordyne FG7SK unit.
Hints your main board is dying
- The entire system has to be powered down and back up more often than not for the system to continue working
- AC or heating system does not initialize correctly
- There may be some sort of code instantly appearing somewhere on the board
