T7WE62310 Genuine Control Board for Mitsubishi Electric Air Conditioners, Replacement Control PCB

Part T7WE62310 is a genuine Mitsubishi Electric control board for the brand's air conditioning equipment. Mitsubishi uses very similar numbers for its control and power boards, and a board for one unit won't necessarily work in another. Read the number from the label on your existing board, or from the parts list for your unit's model, and check it matches T7WE62310 exactly.

Mitsubishi Electric aircon showing error codes? The control board's role

The control board is the brain of the unit. It reads the temperature sensors, talks to the other unit or the controller, and switches the fans, valves and compressor drive in the right order. When it fails, the system might not start at all, show an error code or flashing lights, stop partway through a cycle, or ignore commands. A faulty board can also be the result of another problem, such as a power surge, water getting in or a shorted fan motor, so it pays to find the root cause before fitting a new one.

Who should fit this board

Air conditioner boards work with mains voltage, and inverter systems have capacitors that can hold a charge after power is removed. Isolate the system at the switchboard and the outdoor isolator, then wait several minutes before touching anything. This job belongs with a licensed electrician or licensed air conditioning technician. Photograph every plug and wire, and copy any switch settings from the old board.

Questions about this part

Do I need to set anything on the new board?

Some Mitsubishi Electric boards have switch or jumper settings that need to match the old board, so compare the two carefully before installing. Your technician will check these as part of the swap.
