International Comfort Products TCH236AKA1 Control Board
It is impossible for your furnace or air handler to even activate without the control board installed as it should be according to the manufacturer. The control board is constructed to command everything including the gas valve, the igniter, all the various sensors as well as the air circulator all together. The board that you will choose is supposed to have a part number that matches the brand and the model of your International Comfort Products TCH236AKA1 unit. Be very careful upon choosing a board as a replacement due to so many small differences in models within certain brands.
Key indicators that my main circuit board is dying?
- The furnace or AC is unwilling to work properly
- Could be an a certain error code showing up somewhere on the circuit board
- Power to the control board has to be turned off and back on quite a lot for it to work
