Central A/C sound out: Blower not turning sour? I am slowly isolating a problem with my ac element. ...

I am slowly isolating a problem with my ac element. It seems I enjoy 2 problems and I don't know if they are related. 1. the circuit in the house keep tripping and 2. the blower on the furnace is not getting the signal to shut off (the merely way I can turn it past its sell-by date is by manually flipping the switch at the furnace and cutting the power). I can run the a/c component for 5 minutes at a time, raise the thermostat so it shuts bad, and then contained by a few minutes lower the thermostat - fan blows the entire time. I'm doing this to save it bearable while I figure out if I can fix this.

Any thoughts would be appreciated [I be determined thoughts about this problem, not your thoughts within general. : ) ]
Answers:    Does your thermostat own a fan auto/off/on switch?
If it does, take home sure it's set to auto.
There are two circuits involved with the important A/C,
One for the outside condenser unit, and one for the inside nouns handler. If it's the outdoor unit, it may be running low on refrigerant.
If it's the atmosphere handler, your motor may be on its way out.

Make sure the systems' filter are clean.
Our AC be doing the EXACT same thing. Luckily our neighbor be an AC repair guy, he came contained by said it was the blower motor inside. It wasn't the right size motor for the part. He said the condensor was accurate, the thermostat was obedient, so he replaced the blower motor for $200. This was a couple months ago. If you can find a friend who know an AC guy, he can usually do it off the clock for a cheap price. Hope this help!
