Compressor failure
Main PCB failure
Check point 1. Check connections of outdoor unit electrical components
•
Check if the terminal connection is loose.
•
Check if connector is removed.
•
Check erroneous connection.
•
Check if cable is open.
→ Upon correcting the removed connector or mis-wiring, reset the power.
↓
Check point 2. Check outdoor fan and heat exchanger
•
