Posted: Fri Feb 24, 2006 11:30 pm Post subject: Air Compressor Repair Help

I purchased a 5hp, 26 gallon air compressor from  Harbor Freight.  It worked well for a year, but now will barely  turnover and will not develop full rpm and, therefore, will not  compress air.  A friend of mine tells me the compressor is trying  to start using "run" current.  I've checked the circuit breaker  and the centrifugal clutch switch that triggers the start vs. run  circuit.  They both check out fine.  The oil level is correct  and the compressor cylinder appears fine.  I have removed the  start capacitor, but haven't had any luck finding a replacement.

  

  Three questions:

  

  Has anyone else solved a similar problem and, if so, how?

  

  Does anyone know where I can get an air compressor start capacitor?

  

  If I have to change the entire motor, is there a cheap (cheaper than buying another compressor) place to buy one?

  

  Thanks in advance for your help.

Most electronic supply houses & just about any heating & air 

conditioning supply house should have a replacement that will work. Take 

the old one with you & find one with equal or higher voltage rating & 

uFD  rating that's somewhere close to the value on your old one. If you 

go to an electronics house, be sure they understand that it's for AC 

operation, not DC.



I think that HF sells motors, too.

Every HF electric tool I've ever bought has come with spare brushes.  No

other tool company I've ever bought from has needed to include extra

brushes, so I've always assumed HF motors are junk.  I don't know jack about

electric motors or capacitors, but if its from HF I'd check those brushes.

Ted,

Your friend is exactly right.  Without doing a load test or other 

diagnostics, plain and simple they use very cheap motors in the "off-shore" 

products Harbor Freight sells, especially the motors.  For about $100-$200 

you can get a well suited Dayton motor from Graingers.  Bottom line...you 

get what you pay for!
