Mitsubishi PKA-A12HAL Control Board
Heating and cooling systems will not even operate without the main control board installed as it should be according to the manufacturer. The control board is constructed to command the gas valve, the ignition igniter, all the sensors and the blower all in one unit. The selected board will have a matching part number that will fit in both the make and model of your Mitsubishi PKA-A12HAL unit. You must be sure when you are deciding on a replacement due to differences in models and types.
Subtle hints your main board needs replacing ASAP
- The HVAC system has to be turned off and back on quite a lot for it to run correctly
- The furnace or AC is unable to run correctly
- There seems to be a flashing error code shown on the front of the control board
