International Comfort Products TCH436AKA1 Control Board
The system will cease to run at all without the main control board configured and seated properly. The control board is created to command the gas valve, the igniter, the flame sensor as well as the blower all at once. You should always be careful when you choose a control board due to differences in particular brands and their models. A replacement board will have to match part numbers both the make and model of air handler system you have.
Some warnings your primary control board is not going to last much longer
- The whole system has to be reset habitually for it to run
- System has lit up error code suddenly appearing on the front of the control board
- The HVAC system is not able to operate properly
