Just got my mini ready for paint and boom goes the compressor
Can any one help it’s a 4 hp twin pole 240v single phase motor . I fitted a new capacitor and that lasted 1 minute then boom . Can any thing other than the motor cause this to blow abit reluctant to buy a new motor if something on the compressor would cause it to blow ?? Pump it free moving ! And when it blow yesterday there was no pressure in tank as it only ran for less than a minute .
Help please as mini is desperate for it’s top coat .

Looks like the centrifugal start contacts are not opening, causing the start cap to overheat.

Thanks for the reply and link my motor turns out to have a start and run capacitor so no switch.The shop that gave me the replacement capacitor gave me the wrong type just a start one rated 250v not a start and run type rated 450v . So there giving the correct one so fingers crossed that works if not it's a new motor .
Cheers

It turned out to be the capacitor only :) fitted the correct 450 v start and run type and this happened

I've had the start windings (iirc that's what they're called) go on mine before which eventually lead to the capacitor going.
Replaced it and it lasted a bit longer but eventually went again.
