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?

Sounds like a motor problem.

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.....
