Lennox CB27UH-036 Control Board
The Lennox CB27UH-036 control board is designed to direct everything including the gas valve, the igniter, all the sensors as well as the blower all at once. Your system definitely will not activate unless the control board is hooked up and is correctly configured. Be absolutely sure when you choose a control board due to differences in brands, models and types of systems. The control board you choose should have a replacement part number that matches the brand and the model of the unit in question.
What happens when my primary control board is crapping out?
- Power to the circuit board has to be turned off and back on quite often for the heating or cooling to kick in
- Could be an some sort of error code shown on the board
- The HVAC system is unwilling to run period
