Repair of PUHZ-ZRP100YKA, PUHZ-ZRP125YKA and PUHZ-ZRP140YKA electronic boards for Mitsubishi Electric outdoor units
What are the electronic cards for Mitsubishi PUHZ-ZRP outdoor units used for?
Mitsubishi Electric PUHZ-ZRP100YKA, PUHZ-ZRP125YKA and PUHZ-ZRP140YKA series outdoor units are equipped with a number of electronic cards for complete management of the air-conditioning or heat pump system.
In particular, these devices can be equipped with the following cards:
- Compressor power board: BH76B601G03, BH00B616B09D50702, BH76B852G01, BH00B851
- Control board and fans: BH76B395G01, BH00B614B24Y11004
- Control board and fans: BH76B810G01, BH00B809B
These electronic boards control all the essential functions of the outdoor unit: compressor power supply, fan management, communication between the various components, power regulation, safety control and monitoring of overall system operation.
Failure of one of these cards may result in a total system shutdown or prevent the outdoor unit from starting up.

Troubleshooting on Mitsubishi PUHZ-ZRP electronic boards
We regularly work on the electronic boards fitted to Mitsubishi Electric PUHZ-ZRP series outdoor units. The most frequently encountered breakdown is a total failure of the outdoor unit. In this case, the system either fails to start at all, or remains completely inactive despite a request for operation. This failure may be caused by faulty electronic components on the power board, a power supply failure, a fault in the control circuits, or an anomaly affecting compressor or fan management.
Depending on the situation, the outdoor unit may show no sign of operation, remain locked at standstill or trip as soon as it is switched on.

Each electronic board is picked up in our workshop in order to precisely identify the source of the fault and the defective components responsible for the malfunction. Our technicians carry out a complete diagnosis of the power and control boards. Faulty components are replaced, and the board is inspected and tested before being reshipped.
In many cases, the repair enables the Mitsubishi outdoor unit to be put back into service without having to replace the entire equipment, thus reducing intervention costs and downtime.
