Yup, that's what happens. Check the oil weekly.
I must see atleast 1 a month like that. You would be surpised how many car dealers blow up compressor for not checking the oil. We now install low oil shut switchs to prevent that problem.
If you give me make & model I may be able to get you the parts.
hey scorn, I've got a crappy consumer model oil-less air compresson that makes a buzzing noise and flips a circuit breaker. what should I check for to see if it's repairable?
It didn't have many hours on it and I've already replaced it but I'd like to use it as a vacuum pump for another project.
We do a lot of repairs for Grainer on all there Speedaire & Dayton compressors. Most are now made by Champion but have the Speedaire nameIts an old Speedaire, but I already bought a new compressor pump. I will keep you in mind the next time I need parts for one though, thanks!:biggthumpup:
Does your compressor have a tank?
Does it trip the breaker after it's cycled once? Once the unit is done running you should hear a little air blow out.
A compressor needs to unload after it finishes it duty cycle so no air is left in ths cylinder. That air in the cylinder will put a load on the motor and cause it to trip breaker. You could have a bad check valve allowing air to leak back to the cylinder or the unloader may be badand not letting the left over air escape.
Hope this helps. If you have more questions I'll pm you my number and I can talk you through the problem
If the motor just humms. Your motor probally has a bad starting capasitor.
You can try getting a replacement from Grainger or a Electric motor parts house.
Just take a rubber handled screwdriver or pair of pliers and put it across the 2terminals on the capacitor if it sparks then the charge is released if not there is probably no charge on it. Of course make sure there is no power applied to it when you short out the two terminals. Don't know if you have a meter to test microfarads but most digital meters have a symbol on them(uF) which stands for capacitance and you can test the capacitor that way. If you need a new one and can't find one in your area let me know I can get just about anything electrical at the place I work and can ship it to you.
Make sure you disconnect the wires to it before testing.....
we don't check oil.........we're two stroke guys...........
any advice? crap. I forgot to add the picture to my last post. I'll post it up when I go home for lunch.
thanks, I still havn't tested them. should I plug it in briefly (then unplug) before I test them?Sounds like there is a start and a run capacitor both. The start capacitor will have a low microfarads and a high microfarads written on it along with voltage for a rating. (Ex.124-175uf, 370V)The run will only have a single microfarads with voltage written. (Ex. 45uf @440v)
If you cannot see them or get to them I can try to look up the manufacturer of the motor to tell you the ratings on them...
