International Comfort Products H9MPT100J16B1 Control Board
The control board is made to command the gas valve, the ignition igniter, all the various sensors as well as the air circulator all at once. The entire heating and cooling system will not function without the main control board properly connected to the unit. It is of utmost importance when choosing a control board because of the diversity of particular brands and their models. A matching board should have a replacement part number that matches both the brand and model of the system you have installed.
Red flags your main board will not live much longer
- Power to the circuit board has to be powered down and back up more often than not for the thermostat to kick in
- System has a numbered error code suddenly appearing on the control board
- The HVAC system cannot do anything whatsoever
