My compressor stopped kicking on over the weekend. I noticed that the breaker in the garage is in the 'blown' position, but when I turn it off and back on again it stays in the 'blown' position. By 'blown' I mean, not tightly in "On" and it has play in the switch. It's a 30amp 2-pole breaker. No other power in my house appears to be affected.

1. Would my compressor be on it's own circuit? (30 amp 2-pole)
2. If so, is it a problem with the breaker or with the compressor? I tend to think it's the breaker because I can't turn it back on at all, even when nothing is pulling from it.

btw, I checked the fan in the compressor and it spins easily. What else should I check in the compressor?

It could be a couple of things. First, keep the breaker off. Next, go outside to the condenser and pull off the cover on the control panel. Inspect the dual run capacitor for any bulging. Next, follow the wires from the contactor to the compressor. This will mean that you'll have to remove the top cover of this condenser. Remove the plastic cover off of the compressor, and inspect the wire terminals. Sometimes I see a failed wire connector, which will cause a wire to fall off and short across another wire. If these wires look good inside the compressor cover, then remove the 3 wires, and ohm from the copper pipe to any of the 3 terminals on the compressor. If you read any resistance, then you have a failed compressor.

Good luck
