    Can you provide a little more information? Does it only trip on startup? Every time? How long is the wiring from the breaker to the compressor? What gage is it? What compressor model?

I have a model #919.167200 5hp, 20gal. air compressor. It has been working great for years, but when I went to turn it on today it blew the breaker. I pulled cover and cleaned contacts on pressure switch,...

Hi dtsorrell...

If your somewhat of a mechanic/electrician then you can by-pass the pressure switch by hooking the color coded motor wires together with the incoming color coded wires from your power cord in the proper order.
Plug it in and then check to see if it blows the breaker again, if it does then it is your motor that is faulty.
Please take time to rate me.

I have an Armstrong air conditioner scu10e60a-2 on the compressor is the any kind of fuse that is in the plug that has run/common/switch cause as soon as you plug in breaker on wall blows

If the breaker does not trip with the plug not connected to the compressor, then you either have a bad run capacitor or the compressor is internaly grounded and is bad.

Compressor runs and compress air,but when air setting is depleted compressor will not start to compress more air.If you waite it will start some times do think this might the compressor switch

If it doesn't try to start, then it could be the pressure switch. Another suspect could be the thermal overload on the motor. The motor (or just the overload) might be overheating and shutting the unit off, then allowing it to restart when it cools.

Is there any humming, or does it blow the breaker? When ot shuts off, do you hear a brief hiss of air?

If there is humming or breaker blowing on restart, or no hiss of air at shutoff, the pressure switch unloader valve is probably bad. If the air blows off, and there is no humming, and the compressor doesn't reliably start, it is probably the pressure switch. If pressure drops too low, give the pressure switch a tap with a screwdriver. If it starts then, the pressure switch is your problem.

Keeps blowing the breaker... only 6 months old

This compressor is small however like other brands in this size range draw 13 - 15 amps. Thats quite a bit of power. The compressor has a thermal breaker that will begin to trip if compressor is hot. I am assuming that the breaker that is tripping is the one on the compessor. I have seen many hitachi breakers fail. Easy to replace with generic 20 amp, cost about $10. Before you replace anything, check amp draw with meter, if within specs try to determine what is causing heat.
cycling too many times per hour (check manual for recommended)
low power due to weak circuit or extension cord
using generator for powering compressor (not recommended)
using low quality oil (use synthetic if hot climate)
air leaking from intank checkvalve back to pump
If no reason to overheat then replace breaker on compressor to 20 amp but watch for overheating. Good luck

First check for bunrt wires that can be grounded, then you can disconnect the compressor and plug the freezer and if doesn't blow the breaker , the compressor is bad ,if still blows them ,put the compressor back and try the fan , then try the other fan(inside one) or also could be the light switch, or the defrost heaters.

Breaker blows out when starting up compressor

there are a number of possible causes. you really need an amprobe to read the draw as the compressor starts up. Then check the label on the motor. There is also an unloader in the air loop that allows the unit to start up with no air pressure against it. to help you you really need to give alittle more info.
