What if all 3 readings are the same?

This is probably a stupid question - but the fridge needs to be plugged in when testing the compressor with the meter right?? Is there any chance of getting zapped when doing this testing??

Thanks for watching. It's safest to unplug the fridge before doing any tests. You can see all the tests in more detail in this troubleshooting guide: kzbin.info/www/bejne/hH-naX1umb2kgJI

My refrigerator (Samsung RS277ACRS/XAA-0000) stopped working after a power outage. The ohm readings on the compressor are: C-S: 0.4 ohm C-R: 3.4 ohm I was wondering if such a low reading on the start winding is normal for this model. The Start Relay (thermistor, DA35-00135A) was not showing continuity (R = 1300 ohms), so I replaced it. The new one couldn't start the compressor either. When I test the new one, it also does not have continuity (R = 4000 ohms). I do not know if I got a bad start relay, or my compressor is bad, and by pulling too much current burns the start relays. The overload protector has continuity, and seems to be fine.

Thanks for watching. There are a few notes: Generally the start winding has the lowest resistance. 0.4 ohms seems quite low even for a run winding. Not certain of any models with that rated resistance for the windings. The start relay resistances seem very high, but make sure you are not testing them just after the fridge was running as the resistance increases with temperature. It's also best to check the capacitor to make sure it is good. If those are all still good then it could be a shorted compressor.

Amazing!
