The DIP RG00V525 H54‑MR board is a Mitsubishi HVAC control module used in ductless mini‑split systems to manage compressor, fan, and thermostat functions. Common failures on this class of boards include burnt or tripped protection diodes, degraded MOSFETs causing compressor lockout, and corrosion‑induced open circuits on the I/O traces. First‑check diagnostics: verify 24 V DC supply to the board, inspect for visible burn marks or loose solder joints, and read any fault codes from the system’s diagnostic LED or serial output.[oss-gpt-20b] |
