Mitsubishi PKA-A18HAL Control Board
The control board is constructed to command the gas valve, the ignition igniter, most sensors and the blower all together. HVAC systems will not run at all unless this important circuit board is accurately installed and configured. A matching board should be compatible with the brand and the model of your Mitsubishi PKA-A18HAL unit. You must be careful while searching to pick up a replacement control board because of the diversity of models and types.
Do you know if your HVAC circuit board is crapping out?
- The entire system does not go period
- Everything needs to be reset all the time for the furnace or AC to kick on
- There seems to be lit up error code being displayed on the front of the control board
