I have an old craftsman 3hp 25G air compressor #919.721530. It will only run for about 30 seconds and then shuts off everytime. The compressor is on it's own 15amp circuit straight off a new breaker panel. The scoket is no more the 1ft from the breaker.

Was wondering if anyone out there may seen this before. If so, please comment.

I can not find a manual for this model anywhere.

Thanks so much!!! :)

Hard to say. Guessing the motor is bad. Can you isolate the motor from compressor?
Can you check the amp draw?

some of those older craftsman compressors really had a large amp draw and it causes the breaker to trip, it can be even rougher in wintertime when that compressor oil is thick. You might try a larger breaker say maybe switch to a 20amp and see what happens. Just my 2cts.....
