How to Determine Compressor Damage?
1 Answers
Methods to determine compressor damage: 1. Use a multimeter to measure power supply: If there is an internal short circuit in the compressor, it may not be detectable. If power is shown but the compressor does not start, and replacing the start capacitor still doesn't work, the compressor is likely damaged; 2. After the air conditioning compressor is damaged, there are obvious fault symptoms, such as winding short circuits, windings touching the casing and grounding, increased compressor vibration and noise, compressor seizing or stuck pistons, and damaged thermal protectors; 3. Measure resistance with a multimeter: There are three terminals on the compressor, labeled S, R, and C. The sum of the resistances between SC and RC should equal the resistance between RS, allowing for minor deviations. If a significant difference is detected, the compressor may be damaged.
