Lennox G40UH-36A-070 Control Board
The control board is made to operate the gas valve, the igniter, all the various sensors and the blower all in one unit. The HVAC system will be unable to activate lest the circuit board is configured and seated properly. You must be careful when you decide to replace your control board due to variances between certain brands. A control board that you have chosen will have to be compatible with both the brand and model of your particular system.
What are the indications that my main board is on its last leg?
- Could be an error code indicated directly on the front of the control board
- Air conditioning or heating system ceases to work at all
- The power to the system has to be powered down and back up more often than not in order to operate
