Carrier 25HPA536H0030010 Control Board
The Carrier 25HPA536H0030010 control board is created to oversee everything including the gas valve, the ignition igniter, all the various sensors as well as the air circulator all in one unit. Most systems will not operate whatsoever unless this board is in its proper place and configured for your unit. You must do some research when you choose a control board due to differences in models and types. Any control board you choose should be compatible with the brand and the model of HVAC system.
What are the indications that my main circuit board has to be replaced?
- The entire system has to be powered down and back up many times a day for it to kick in
- The HVAC system refuses to work period
- There is numbered code suddenly appearing on the control board
