International Comfort Products GNL125N20C1 Control Board
The International Comfort Products GNL125N20C1 control board is constructed to direct everything including the gas valve, the ignition igniter, most sensors and the blower all together. The HVAC system will be unable to run at all unless this important circuit board is configured and seated properly. A matching board must have a matching part number consistent with both the brand and model of your International Comfort Products GNL125N20C1 unit. You must do some research upon choosing a board as a replacement due to the vast differences in systems.
Clues to watch for in a failing main circuit board
- The system has to be reset rather frequently for the system to operate once again
- Entire unit ceases to operate correctly
- Could be an a flashing error code appearing on the control board
