Hi, have a problem on my big compressor. Its got a newish motor on it but last week it decided it wouldn't start, well it would spin a couple of times then stop, so:
1) I checked both capacitors - motor start capacitor looks to have leaked so replaced it. It then spun up faster then started to go on the normal higher speed but then cut out
2) Replaced the run capacitor - looked slightly swollen on closer inspection. Motor now starts spins slowly, begins to speed up to about half speed, then slows back down to starting speed, speeds up again, slows down again etc
I'm out of my depth now, what do I check next - all I can think of is to bypass the pressure switch in case it has failed in some wierd and wonderfull way OBVIOUSLY I'm not going to try use it like this other than as a test.
Help?
