Common failures include worn or pitted relay contacts, cracked solder joints on the power input terminals, and failure of the integrated control IC due to overheating or moisture ingress. First‑check diagnostics: verify 12 V DC supply voltage at the board’s power pins, inspect for visible burn marks or loose connections, and read any stored diagnostic codes from the unit’s main controller.[oss-gpt-20b] Post Comment
