Mitsubishi Electric E22G59452 Control Board

The Mitsubishi Electric E22G59452 Electronic Control Board is an OEM control PCB designed for compatible Mitsubishi Electric HVAC and ductless mini-split equipment. This board is used as a replacement control component in systems where part number E22G59452 is specified.

As with any Mitsubishi mini-split control board, correct model and serial-number matching is important. Connector configurations, sensor inputs, communication circuits, and control logic can vary between Mitsubishi equipment models.

Before replacing the board, a qualified HVAC technician should verify incoming voltage, wiring harnesses, connectors, grounding, sensors, and connected loads. Problems with external electrical components can sometimes produce symptoms similar to a failed control board.

For proper replacement, verify the original PCB part number and the complete Mitsubishi equipment model and serial number before ordering. Proper electrostatic-discharge precautions should also be used when handling the electronic board.
