Lennox G40UH-36C-110 Control Board
The Lennox G40UH-36C-110 control board is constructed to oversee everything including the gas valve, the igniter, the flame sensor and the blower all at once. It is impossible for your furnace or air handler to even operate whatsoever unless this board is configured and seated properly. Be very careful when you choose a control board due to the vast differences in heating and cooling systems. The proper control board will have to be compatible with both the brand and model of furnace or air handler you have.
Indications your Lennox control board is in dire straights
- There may be an error code suddenly appearing on the board
- Power to the circuit board has to be turned off and back on often in order to operate
- The HVAC system ceases to operate properly
