Lennox HPXB15-048 Control Board
The Lennox HPXB15-048 control board is made to operate the gas valve, the ignition igniter, all the various sensors as well as the air circulator all in one unit. The entire heating and cooling system will not run at all unless the control board is configured and seated properly. Be very careful when you are choosing a replacement board due to the many differences between particular brands and their models. The board you choose should match both the brand and model of your heating and cooling system.
Signs your main board is going to die
- There may be a strange code being displayed on the control board
- The whole unit declines to start period
- The power to the system has to be turned off and back on many times a day for the thermostat to kick in
