Genuine Mitsubishi Electric Outdoor Main PCB T7WG30315 – PUHZ-RP100VKA

This is the genuine Mitsubishi Electric outdoor main controller board, part number T7WG30315, for PUHZ-RP100VKA outdoor units. These Power Inverter outdoor units are widely used across Australia on ducted, cassette and light commercial installations, so this board is a frequent requirement in the commercial service market.

The outdoor main PCB governs compressor operation, outdoor fan speed, expansion valve control, defrost and oil return logic, protection functions, and M-NET or serial communication with the indoor unit and controller.

Typical symptoms of a failed outdoor main PCB

• Outdoor unit dead with confirmed supply at the isolator
• Serial or M-NET communication errors between indoor and outdoor units
• Compressor or fan does not run, or the system trips on protection immediately after starting
• Expansion valve or four-way valve not operating, so heating or cooling fails
• Repeated defrost faults or protection lockouts
• LED diagnostic display showing outdoor controller errors
• Visible surge or water damage, blown fuse, damaged relays

Check the error code first

Mitsubishi Electric units provide detailed error codes, and they are worth reading carefully. Many faults that look like a board failure are actually a failed thermistor, a shorted expansion valve coil, a failed fan motor, a loose terminal, or a supply voltage problem. Read the code, record the LED pattern, and have a licensed technician confirm the diagnosis. Send the code and photographs to us and we will help match the correct part.
