Ingersoll Rand Type 30 model 253 D 5, ser 279262 motor hums then it will trip the breaker
Good morning Bill,
My father in law has the above mentioned compressor, the problem is when it builds up pressure and cuts off when it tries to restart the motor hums then it will trip the breaker, we have ordered the pilot valve to replace it, it was leaking air around this fitting. any other suggestions or advise greatly appreciated, is there a downloadable manual for this model.

Ron, empty the tank completely and then try to start the T30 air compressor.
Did that make a difference?

T30 5HP 1PHASE WILL NOT START
COMPRESSOR WHEN SWITCHED ON WILL NOT DO ANYTHING TOOK MOTOR TO SHOP THEY SAID NOT BAD STILL NOTHING HAVE POWER TO PRESSURE SWITCH AN MOTOR WHEN I PUSH IN ON STARTER HOW DO I TEST STARTER OR SHOULD I JUST REPLACE 20YEARS OLD THANKS RICHARD
The IR T-30's have been around for about 90 years, so they are a proven product.
Dump all the air from the air compressor, and then turn the power back on.
Assuming is still does not start, just to confirm, you have traced the live power to the pressure switch, and from the pressure switch to the motor starter?
If nothing is happening at this point, and the motor is good, then power cannot be getting through the start capacitor to the motor.
I'm surprised that when you had the motor checked, they wouldn't have tested the capacitors for you too?
Regardless, there is a page on how to test electric motor capacitors linked from the site map page.
