Run capacitor question
Posted 12 July 2006 - 06:19 PM
This may be a stupid question, but when looking at the wiring diagram, it shows a run capacitor hooked to the start winding of the compressor. Would this not make it a start capacitor??

I'm thinking the culprit is a bad breaker, but I'm wanting some other input. When I checked the a/c, it ran fine, pulled about 7.5 amps (rated at 8.9 amps). I couldn't get it to duplicate the problem for me, except when I just turned the thermostat back, then immediately back on again (which I knew would cause the overload to come into play). It tried about 3 times to cut on (pulling about 40 amps) and the 4th time, the compressor cranked up and ran fine. But under normal operating conditions, it ran flawlessly.
I did notice that the a/c is not on a single outlet, there were other receptacles run on the same breaker. But nothing that pulled a lot of amps were on those receptacles.
Anyone else seen bad breakers cause this to happen?

Check your contactor coil to see if it's getting the proper volts and if it is then maybe it's going bad, not pulling in the contactor as it should or the contacts on the contactor are going bad.Either way,if you have volts getiing to the load and the load isn't working the load is bad.I would also check for any bad connections from the transformer to the coil to make sure it isn't a broken connection , making nad breaking.

My gut feeling is that your breaker is bad. Scorching at electrical connections is most commonly caused by poor electrical contact. Excess amperage will usually throw the C/B before any damage to wiring occurs. Most electrical fires are from bad connections arcing/overheating, rather than shorts.
It also sounds like the compressor is having trouble starting. You may consider installing a start-boost capacitor, like SUPCO and other companies offer.
