Lennox CB28UH-042 Control Board
HVAC systems will not run at all lest this board is installed. The control board is made to regulate everything including the gas valve, the igniter, all the various sensors as well as the air circulator all together. The selected board must be compatible with both the brand and model of air handler system you have. You must be careful while choosing a new control board due to the many differences between systems.
Indications your main board is in dire straights
- The furnace or AC is unwilling to do anything well
- The system has to be turned off and back on more often than not for the thermostat to kick in
- There may be a type of code indicated on the front of the control board
