Compressor stopped cycling today, has been working fine. Only change that was made backed pressure down, ran good for about a hour and stopped cycling. Motor turns on but no cycle, is this a easy fix or is it time for a new one. It is one of the little pancake compressors.
I believe my bud is responsible as he mentioned are you still running that old compressor, hour later its dead, I believe that there must be something in the code of carps, that if your bud jinks your tools he is liable to replace it. I’ve tried convincing him all day, but he ain’t buying it. If any body can find the statue in carps code of ethics please post as I need some ammo in the morning.

Does it cycle manually? If so, then maybe your seal is leaking at the pressure switch diaphram, often very easy to fix, just tighten the screws.
Porter cable is running an unbelieveable deal on their 2hp pancake .

If you decide to go new, don't consider the Dewalt/Elmglo concept for more than a nano second before rejecting it....

Why?
dewalt bought emglo ...
took the existing design of a perfectly working compressor ...
didn't change anything ...
then painted it yellow instead of blue or gray ...
and stuck a dewalt sticker on it.
so naturally ... now it's junk.

Well,certain Emglos have issues with current needs and temperature, and blow breakers easily and repeatedly on cycling....at least thats the answer I got when i posted the issue here. Lot's of "They do that often, and so on.
I talked to Dewalt about it, and they said, "Don't use an extention cord in cold temps"
It's a problem.Jake Gulick

I wouldn't use an extension cord even if it's hot where the compressor is being used. I used one on my Rolair and it popped the breaker just about every time it cycled.
"I cut this piece four times and it's still too short."
We don't use extension cords either highfish. Also, we don't plug our compressor into the tail end of a long circuit either. We go to the service panel and plug in there, as close as possible.
How do I know this is important? The kids burned up two compressors on one job!

Hmmmph! Kids! Give 'em new books, and what do they do? They chew on the corners!
"I cut this piece four times and it's still too short."
Well, I do try to get it close to the panel, as a matter of fact, I had my electrician put an outlet right near the panel for service use. The client requested that I use my 25 ft cord (12 ga) instead of the hose because the door closed with the cord underneath....and since it was cold...
no joy...pop went the internal breaker, LOL
Instead, I put the compressor next to the panel and ran the hose out through the window, with a towel stuffed in the crack to keep the client warm!
I wonder how the high pressure MAX is in cold weather??Jake Gulick

What's the matter with the Emglo/Dewalts? I've had one for years and have never had any trouble with it.Coming to you from beautiful Richmond, Va.
What brand of compressor is this?
If you mean that the motor tries to run but can't because there's too much pressure resisting the rotation, attach a blow gun to the hose and bleed off some of the pressure. Also, make sure the tank is drained and there isn't too much oil in it. If the pressure loss lets the motor run, look for a pressure relief valve, not far after the compressor outlet. This is probably sticking (like mine did) and causing the problem. Clean it/give it a couple of drops of penetrating oil and let it soak in, or disassemble it to clean everything. Mine was popping the circuit breaker on the main panel because of the excessive current, but no permanent damage otherwise. This may solve the whole issue for you.
If the pressure tends to bleed down with a noticeable sound, there will be a check valve on the line going to the tank. You can remove this and take the small metal disc(s) out with a snap-ring pliers. If there's any debris keeping it from closing, you won't maintain pressure.
If you can never reach max pressure and the pressure switch kicks off, you may have bad reeds, located on the top of the head. Think of this in the same way as a car motor- the electric motor replaces combustion as the mechanism for rotating the compressor, and an internal combustion motor is just an air pump. If you have a leaky valve (or reed), you have no compression. Reeds and the gasket are cheap. Depending on the brand of the compressor, they may be very easy to find.
Thanks I'll give your advice a try
