International Comfort Products PGME42G0905 Control Board
The control board is created to control the gas valve, the igniter, the flame sensor as well as the blower all at once. HVAC systems will not run without the main control board accurately installed and configured. Be very careful when you choose a replacement due to differences in models and types. The brand of board you choose should have a replacement part number that matches both the brand and model of air handler system you have.
Some warnings your primary control board has to be replaced
- There may be a strange type of error code being displayed somewhere on the circuit board
- The AC or furnace is unable to operate correctly
- The control board has to be powered down and back up repeatedly for everything to run again
