Question about Campbell Hausfeld 28 - Gallon Air Compressor

1 Answer

I have a CH WL611701AJ compressor. The motor starts and runs for approx 15-20 seconds before blowing breaker. I have replaced both capacitors, still blows breaker. Removed piston to allow motor to freewheel, still blows breaker. Made sure everything is off the circuit and still blows breaker. Breaker is a newer 20 amp. Don't have the manual so I don't know the recommended size. However the motor is 16 F.L.A which is close to the 20 amps. Any suggestions

This may seem a bit simplistic but how are you hooked up to the outlet? Are you using an extension cord or is the compressor plugged in only using the supplied power cord?
If you are using an extension cord then you are going to pop the breaker every time you use it. Infact the manual states

"Never use an extension cord with this product. Use additional air hose instead of an extension cord to avoid power loss and
permanent motor damage. Use of an extension cord voids the warranty."
Air compressors don't like extension cords.
It simply draws to much for an extension cord to handle.
Depending on whether or not your warranty is out there is a simple solution. Find the biggest gauge extension cord you can

If your not using an extension cord and it's ran in the past where it's plugged in now then check the circuit because there must be new draw on the breaker

You said the breaker is 20amp. correct? The compressor should be run on a breaker dedicated to the compressor only.

Even though you should use a longer hose instead of a longer power cord you can get away with it. But forget about wire gauge size you need to think wire diameter. The extension cord I made for my compressor is approximately 3/4" thick. That is the only way I was able to use an extension cord on mine. A good place to get that size cable is a boat supply store. The cable used for shore power on boats works.
Hope this helps but if not please let me know and I'll try and help anyway I can to solve your problem.

    I too have one of these compressors, and had the same problem. I had the compressor in my new shop with all new wiring. The compressor was plugged into a 20Amp circuit, and it was the only thing on that circuit. I kept tripping the breaker. I replaced several parts, nothing helped. Finally I moved the compressor to my garage, and I haven't had the problem since. I think in the garage it is on a 15Amp circuit plugged into a GFI outlet. So this is truly a mystery, why it works in my garage, but not my shop.

Have a 21 gal central pneumatic. 2.5 hp. With no pressure in tank, plugged into wall outlet. Upon start up it will run 20 seconds then the breaker on motor case trips. Barely used this thing.

the thermal circuit breaker is overloading
that can be from a faulty tcb or a problem in the compressor ( seized)
most need start/run capacitors for the motor to start and if it / they are faulty then that will blow the TCB
if it has 2 capacitors ( one for start which it is doing and the other for run then that capacitor may be the problem
if it has the one unit with 4 wires , replace the capacitor
suggest that get an electrician in to check out the unit

Trips breaker after a few seconds of run time.

Start capacitors are disconnected when it is reach a full RPM.
Use a AVR tester - measure AC voltage across capacitors. It shall be off in a few seconds after is running.
If not - centrifugal switch or its components are problem.

My ac central air is blowing air but not cold

Problem #1:Outdoor condensing fan motor has stopped running. This problem could be caused by a bad motor run capacitor. If your motor capacitor is not the problem, then more than likely you need a new motor. Is the fan blade tight, stiff or hard to turn? If the fan blade is hard to turn then you probably need a new motor. Problem #2: Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run. The compressor is locked and will not start. What is happening is the compressor is trying to start, but because the compressor motor is locked it tries to start for a few seconds and then because of the high amperage being drawn goes off on internal overload. The internal overload protects the compressor windings from overheating and burning up. I see this many times during the start of the air conditioning season. Some compressors just have a hard time starting after sitting all winter long. Some compressors are locked up so bad that I can not start them and must tell my customer that they need a new compressor . Many times I can get the compressor started again without having to buy a new compressor or new air conditioning system by using the device known as a "Super-Boost." I keep two or three of these on the truck. They have saved many of my customers from having to buy new air conditioning compressor. Another good device is called a "5-2-1" kit.

Das not start only 2years old

I had this problem with a model WL5062 which looks the same. It turned out to be the capacitor on top of the motor. This capacitor provides phase shift. To check if the capacitor is the problem, disconnect the tube between the compressor and the tank. Then try to start the motor. If the motor runs the capacitor is bad. If the motor still does not run the problem is something else. I got a replacement capacitor from a local motor repair shop. CH does not supply these.

Compressor is blowing breaker, fan comes on. Ac worked fine last season. when trying to go to any cool setting, compressor will actually stall generator, or trip breaker if attached to house

You have a faulty start capacitor. The capicitor helps start the motor ... since it is not doing its job, the motor draws LOTS more power from the line popping the breaker. Have your professional RV service center service your AC.

Sluggish on start and blows the breaker on compressor 17amp

replace the start capacitor on the motor body,it is located under a metal cover by loosening 2 screws,it is getting weak,also if you leave this breaker jumped,you will soon over heat the motor windings and ruin the motor

Compressor won't sstay running and trip breaker

You gave a lot of information, but you didn't say if it worked when free wheeling. If not, I would suspect the inertia switch. If it is working, you should hear it click when the motor is winding down after being shut off, at least when free wheeling. A 20 amp breaker will certainly handle a 15 FLA motor, even on startup. They don't trip at 20 amps exactly, especially on a simple overload. Even at twice the rated amperage, it can take several minutes to trip it. They will trip quickly on a dead short, however, or a severe overload. I doubt the windings are shorted or it either wouldn't work (start windings) or would run at a slower speed with the inertia switch constantly tripping in and out with it coasting while tripped in (i.e., accelerate, coast, accelerate, coast, etc.)
