CH air compressor died!

[Owen]

Two weeks after the garage door opener dies, my Campbell Hausfeld air compressor's motor dies! Is this a sign....???

Anyway, does anyone have any experience doing a DIY repair, what to look for when troubleshooting, etc? I read on the net that some motors have a bad temp. sensor.

The wall outlet is still live, I pressed the red button on the side of the motor (reset?) but nothing happened.
Thanks,
Owen

Take it apart and see what you can find. Chances are, your cheap motor(and mine) don't have overheat sensors. Check the capacitor start circuit to be sure it's working properly. There should be a centrifugal switch that disconnects the capacitors when the motor speeds up. Mine was broken causing the motor not to run. The pivot was broken so I just made a new one and I was back in operation. At the worst, you may have cooked the motor and you'll need to go to Harbor Freight to buy a new one.

Yep that's a real good place to get one, That way you can go back again next year.

The simplest thing to do if you don't feel comfortable working on it is to take the motor off and go to a "motor rebuild shop". In short order they will tell you what the problem is. They will also be able to recommend the proper replacement if it can't be fixed. Air compressors require drive motors with a high starting torque. Look for "compressor duty" on the label. If your motor starter does not have "overload protection" then your going to want a replacement motor that is "Thermally Protected" and probably with a "manual reset" as compare to "automatically resetting". Seek out a local professional. Maybe you only need some new caps or the speed switch as pointed out about has a problem. Do your self a favor and take it to someone who knows what they are doing. And DO NOT BUY a replacement sight unseen from Harbor Freight. JMHO.

Thanks everyone,
I was thinking of calling an authorized shop and asking them what to look for. If I have to replace it, I'll get a CH one with the overload protection.

A friend also mentioned Northern Tools as a source, I'll look into them after I talk to a shop.

I have used Dayton brand electric motors from Grainger for years.

I bought a USA GE motor from HF last year....I looked real good to try to find the China label but it was a US unit. I almost fell over....

Dayton motors from Grainger are real good units, too.
