After running for awhile electric motor get hot shuts down and I have to wait an extended period of time before normal operation. What could be the problem?

How long is running it “for a while”?

My rule of thumb for smaller air compressors, particularly those that are not rated for 100% duty cycle, is 10 minutes on, 10 minutes off to allow the motor to cool.

If this is a new circumstance, and nothing else has changed including the power supply and the length of run time, advise as a comment here, and we’ll press on helping you resolve the issue.

My compressor is not a small one it’s rated to use with air tools and spray paint tools air nailers tank fills up fine but after it on and cycles a few times the electric motor is very hot and the compressor just stops working

Not a small compressor
by: Bill

I certainly didn’t mean to insult your air compressor, friend. Small is a relative term, and, now that I’ve gone out and found an image of the same type of compressor you’ve got, in the overall scheme of things, a 2 HP is a small compressor.

Having said that, if the problem is a new one, and nothing else has changed – power supply, length of power cord, length of time used each time, and the motor is now overheating, my inclination would be to determine if the start / run and or start and run capacitors are working properly.

They (it) are located on the side of the motor near the shaft end. See the page on this site about how to test them.

Again –

Please specify what “a few times” means, and over what period of time?

How long is the motor off before it turns back on?

How do gain access to the capacitors for checking and thanks

James, as I said, “They (it) are located on the side of the motor near the shaft end. See the page on this site about how to test them.”

You will have to dismantle the shroud and possibly the motor cover to find them.

Can you identify the motor itself?

You should be able to get the cap specs from that.

Capacitors

Hi Bill
Finally got to the capacitors on my compressor one of them it was obvious that it was bad and I think that it is the start capacitor.

My only problem is that there are a lot of numbers on it and I don’t know which one is the part# some are even rubbed of I have been on line to find replacement but don’t know which series of numbers to use I need help in this matter.
