Air Compressor Pressure Switch Repair Video

30 Year old compressor that need fixing.

@mythril4 Thanks. ...
@mythril4 Thanks. ? I'll keep that in mind.

Watch out for that ...
Watch out for that tank, it may be a? very dangerous tank by now. Old tanks like that, especially those ones (being non-industrial) corrode on the very bottom. Over time the corrosion turns the metal very thin, this makes the tank prone to rupture. Check valves should also be cleaned annually or bi annually, they get very hot, old pumps spew a bit more oil, this creates an ignition point if the oil mists in the tank. It's rare, but does and has happened more then once.

Is that a start ...
Is that a start capacitor-black or a run capacitor- silver on the motor. Check amperage draw. it should be 17.5-18amps under load if its higher. check the centrifugal switch. sometimes the? contacts get dirty or burned. other than that it could be the capacitor.

@jp2son dont use a ...
@jp2son dont use a long cord if you do use heavy guage wire . the motor may have some burnt wires in the winding switch? is fine.

try hooking up your ...
try hooking up your compressor whit out your regulator and see if? the breker pops also check if the motor is getting hot

@utubejohnny1 try a ...
@utubejohnny1 try a new pressure switch sounds like your diafram? has a hole in it.

22 amp breaker ...
22 amp breaker needed?

What? if the ...
What? if the compressor, just keeps pumping and the tank won't fill? what should I do?

@jp2son Your ...
@jp2son Your first pressure switch was the correct one. You have it? wired incorrectly. There are two contacts with two screws on each contact. Which are L1 and L2 Looking at the top. First two screw are for either you black or white and same for the black. Just make sure each black an white are paired with each other.

@jp2son Yeah, ...
@jp2son Yeah, that's a good idea.? Thanks for watching.

Third, Put a meter ...
Third, Put a meter on it to see how many amps it is drawing. Check your breaker capacity as well. Keep in mind that just because a breaker resets, doesnt mean it is good. Hope it works out for? Dads old compressor! I know how it is... good luck and have fun, J

First of all, the ...
First of all, the small copper pipe is simply an unloader, and the relay? senses the pressure from the BIG pipe, not the small one. The small one just reduces the head pressure for startup. I have my small line crimped, and going on 10 years with no problems. Second, If this compressor has been sitting for many years, then I would suggest taking the head off and inspecting the cylinder walls, or, at the very least, misting wd40 in the intake while running at no load for a bit.

If you suspect ...
If you suspect motor then remove drive belt and leave it running for 4 or 8 hours and see how hot? it gets. If it get really hot off load then its knackered.

When you say ...
When you say breaker. What type? of breaker. Is it an earth leakage trip breaker or over current breaker. If its an earth leakage breaker tripping someone may have had the problem in the past and disconnected the earth to bodge it. However this is dangerous. However in the UK some types of breakers are not suitable for welders or motors so you can only use good old fuses in your elecky panels.

Awww crap...someone ...
Awww crap...someone taught me you are suppose to go? AGAINST the threads when using teflon tape...p**s!!!

put a switch on? it ...
put a switch on? it. not difficult.

@chuckdavidson87 ...
@chuckdavidson87 I'll look? into that. Thanks for tip and for watching.

could be that the? ...
could be that the? check valve is not seating, causing back pressure. There should be one coming out of the comressor head.

@jujuwooley I'm ...
@jujuwooley I'm going to try? a new power cord first. If that doesn't work I'm afraid it's the motor windings and a new motor costs too much to put into this compressor. Thanks for watching.

change all the wires? in it

@mrwiggles2 ...
@mrwiggles2 Thanks. Sounds like you know? what you're talking about. It's starting to make sense. I think I have to much into it already but I just might fix it anyway since it was my Dad's and he past away last summer. Thanks for the help.

Paiste- motor is ...
Paiste- motor is shot. Its drawing too many? amps due to bad windings. Its common for that to happen on an old motor. At 80 psi that motor is really working. Get yourself a new one- get two capacitors... Or see about getting it rewound. I think a new one will cost less.

@cat123456789101 ...
@cat123456789101 Maybe I can put a meter on it to check.? Thanks.

@KrankieV2 That? ...
@KrankieV2 That? could be. Thanks.

could be a shorted winding in? the motor

maybe it is the? power cable, since it is so long it might have some damage in it. just a thought.
