My Mac 5200 won't budge: no noises, strain, clicks or vibrations. Just quiet dead. There's power to the pressure switch when I flip the unit on (as measured by voltmeter), so whatevers going on sits deeper inside it.


Hints: I used it last week, all was fine; then I drove it 200 mi. It clicked and chugged briefly before it died,

Rats. Any & all ideas most welcome.
Thanks

Jim:

There is an overload 'switch' mounted near the fan end of the motor. I don't know if it's supposed to reset or if it is manual, but it's worth a look.

If that's the immediate problem, then I'd check the capacitors while you have it apart.

With the tank empty of air, use your meter to see if power is crossing the pressure switch to the motor circuit.

If so, then power is getting to the motor, and absence of any sound would indicate that the motor isn't trying to start.

That being the case, see the page on this site about testing your start capacitor - under troubleshooting - as that is the likely culprit.

Cheers,

Bill
