Hi guys,
I've got a ice cream display which when the compressor turns on it trips the circuit breaker. I have ruled out loose connection etc. and it all points to the compressor.
What I have found is that the run capacitor which should be 20 uF is 14 uF and the Start relay contacts have arched and corroded away. I am going to replace both of those. (I changed the capacitor and tried the relay after cleaning and sanding down the contacts, still the C.B kept tripping).
Anyway going to my original question
I measured the coil resistance of the compressor and I get:
Common ---- Run = 1.5 ohms
Common ---- Start = 5.4 ohms
Start ----- Run = 6.9 ohms
Does this look alright, 1.5 ohms seems low doesn't it? and I also checked whether the compressor was grounded and it wasn't.
Any help would be greatly appreciated.
