compressor help

[madboy]

was useing my compressor today and the air was getting low but the motor would not cut in ,so i shut it of to restart it and it wont start up it sounds like the motor is trying to ingage but it wont turn over, there what looks to be a coil pack ontop of the motor ,iy smells a bit dodgee anyone help

[Dave]

I think that coil is a capacitor. Touch the terminals and you will find out (do not do it!)
Sounds a bit like it might be that bit that is knackered. Best get a sparky to have a look really.

you can get a start capacitor from a city electrical outlet amongst others, have you removed the belt to check if motor spins ok by hand ?

yer,you can turn the pullys and they rotate easy,please any help very muck appreciated

[alladdin]

switch it on with your hand on the motor (safely !) does the motor hummmmmmm ? or does it blow the fuse / trip out ?

[Dave]

Switching it on with your hand on it when you know there is a problem is not the best idea in the world.
Get a sparky to have a look at it!
Whatever it costs it will be a lot cheaper than a new compressor or a funeral.

if you switch it on you can clearly hear it humming but it doesnt trip or blow fuses

try maplins there great for all things like capaciters , if its readable there should be a microfarad rating and voltage of the unit ,failing that get on to the company who made the compressor via phone and ask for the details .....once you got the spec on the capacitor ,,,maplins or an rs components store will be able to give u a relpacement
DO NOT TOUCH THE TWO ENDS your get a proper whack !!! short the two terminals with a insulated screwdriver ( with the unit UNPLUGED)
hope this is of some help

i've got an sip ( direct drive) compressor... mine did the same... it wouldnt fire up.. just made a hummmmm,,,

it was the starter capacitor... it had blown it's self to bits

anyway a new one did the trick.. but now the rings have gone.. doh !!!

where did you get it from

[avopaul]

reading pnumatics do them about £15 each

[chrisb]

got mine from excel compressors in hyde ( gt manchester ).. All you need is the numbers off it...

cheap as chips...

[alladdin]

dave wont like this

when its hummin , try giving it a spin on the pulley in the correct/normal rotation. if its the starter cap then it will probably spin up to speed when you give it a head start

edit, dont do this with the belts on as it might grab you

ffs

:d

[boombang]

Is this a 13 amp unit on regular plug?

If so is there anything else that's just been plugged in on the same circuit?

I had to put a new ring off the mains for my garage, otherwise the compressor did as you said - buzzed but didn't start running.
