HOW TO MEGGER TEST A HVAC COMPRESSOR

Testing your Air conditioning, HVAC motor / compressor windings with megger ohm meter to find out if it's electrically sound or unsound. Is it tripping circuit breaker’s blowing fuses find out why ....Reads below 100 Meg OHM ⚠️ caution possible 🤔 acidic oil, below 50 Meg time to replace motor/compressor

Thank you so much for your speedy response to my comments. Man I need to come to New York and learn under your talent. I have a brother there but I'm in Chattanooga Tennessee.

friendly advise OL stands for open loop not over load

[@D2DNYAC]

I stand corrected, open loop makes sense, thanks for watching

[@richarddomasig514]

Thanks brother..nice video..I suggest you test a grounded compressor as well..😀 test a good compressor and a bad compressor for comparison...

[@D2DNYAC]

Thanks for stopping by, I will do a video on Meg testing a grounded compressor, stay tuned for that

Thank u I’m lock in

you didnt discharge the load wires on the contactor after you meggered them.

[@D2DNYAC]

Interesting how long does that takes to desipate?

[@veloci3twenty607]

@@D2DNYAC instantly if shorting to ground. Leave the megge connected after releasing the test butoon so the tester can discharge the line. The screen will show the voltage drop down to zero.

Crazy how just a contaminated system can show a bad Meg reading

[@D2DNYAC]

That's usually what caused a low megger reading,, contamination = acid = higher oil conductivity and compressor windings insulation break down!
