Possible Causes

Corrupted EEPROM data on indoor PCB, Incorrect PCB replacement without proper configuration, Power surge damage to memory

Safety first: Turn off power before accessing the indoor PCB.

Steps to try:

1. Power reset: Turn off the breaker for at least 10 minutes to allow the control to fully reset. Then restore power and test.
2. Factory reset (if supported): Some Midea remotes or indoor units support a reset function (check user manual). Perform a reset to restore default settings.

When to call a technician: If C0 persists, the indoor PCB may need reprogramming or replacement with the correct Midea-configured board.
