What This Means
Compressor motor mechanically constrained; Liquid slugging in compressor; Inverter circuit solder failure; Control signal loss; Component shorts on inverter board
What actually causes this:
The compressor is physically stuck, has oil breakdown preventing rotation, or has seized bearings
First Thing to Check
Try to manually turn the compressor shaft by hand if accessible; it should turn smoothly
Parts Involved
How to Fix
- 1
