International Comfort Products PYMC36G4 Control Board
The International Comfort Products PYMC36G4 control board is made to command the gas valve, the ignition igniter, all the sensors as well as the blower all together. It is impossible for your furnace or air handler to even operate unless this important circuit board is properly connected to the unit. The selected board should match the model number with the brand and the model of furnace or air handler you have. It is imperative that you select wisely when choosing a control board due to so many small differences in certain brands.
Clues of a faulty main circuit board
- The HVAC system needs to be reset habitually for it to run
- AC unit or heating unit will not run at all
- System has numbered code suddenly appearing somewhere on the board
