E22D98452 Genuine Control PCB for Mitsubishi Electric Air Conditioners, Electronic Control Board Replacement

E22D98452 is a genuine Mitsubishi Electric control PCB, the circuit board that runs an air conditioner's operating logic. It reads the remote and the temperature sensors, then switches the fan, the vanes and the signal to the outdoor unit. Mitsubishi Electric has many control boards that look alike, and our record has no model list for this one, so match E22D98452 with the label on your old board or the parts list for your unit.

Mitsubishi air conditioner not responding? Suspect the control board

When a control PCB fails, the symptoms vary. The unit may ignore the remote, show a flashing operation light or error code, start and stop on its own, run the fan but never cool or heat, or refuse to power up at all. Power surges, lightning, moisture and insects getting into the unit are common causes. Because faulty sensors, fan motors and wiring can produce the same signs, it's worth having the fault codes read and the inputs checked before the board is replaced.

Who should fit it

Air conditioners are hard-wired, so a licensed electrician or qualified air conditioning technician should fit this board. Power must be isolated at the circuit breaker and the outdoor isolator first. Photograph every connector, and the position of any jumpers, before removing the old board, and handle the new one by its edges to avoid static damage. Test all modes and the remote afterwards.
