Craftsman 919.162120 cuts on and off every few seconds

by Anderson Baker
(Angier, NC, USA)

cuts on and off every few seconds never runs more than 2 seconds stays off about 4 seconds then comes on again for 2 seconds. This goes on forever until I unplug the compressor. Mid nineties Craftsman 919.162120. Does this sound like a pressure switch issue? The switch is out of production and I am having problems locating a replacement.

Yes, it sounds like a pressure switch problem to me, as long as your power supply is constant.

To check, pull the pressure switch cover and watch what happens inside as the compressor cycles. If the pressure switch innards are moving - opening and closing points - then it's likely the switch. Careful, live power points inside the switch cover.

As to what to do now, read the pages on pressure switches for tips on replacing one that you cannot locate an original for.

Simular Problem Craftsman 919.167312
by: Lonny

It will build 10 lbs, shut off for 5-10 minutes, it keeps cycling that way until it gets to max pressure. I can hear the pressure switch click before it kicks on again. It is a new pressure switch. Could it be the motor cycling on it's own for some reason, it does get pretty warm.

It is possible that the compressor is cycling on and off due to the thermal cut out preventing motor overheating.

Are you using an extension cord? If so, don't. What is the breaker amperage where the compressor is plugged in? 20 amps would be my preference. Anything else drawing power from the same circuit when the compressor is running, that could be a problem. A faulty run cap could cause motor overheating.

(what Bill said) and:

If this compressor is new to you, there is a possibility someone messed with the switch settings, if it is adjustable.

You might want to play with those before you go for a new one.

Where to find a pressure switch for a craftsman model #919.152920

My compressor has a cracked housing for the pressure switch. Where to find a pressure switch for a craftsman model#919.152920. It seems like there is no replacements available or what is the new replacement.

James, it shouldn't take you more than a minute or two to find a replacement where you are.

You do not need to replace your pressure switch with an OEM make, simply get a pressure switch from your local compressor store that has the same specifications. Those are:

-can mount on your compressor
-has comparable connector for unloader valve
-has same voltage capability
-has same pressure setting as yours or is adjustable

Take a photo of the internal wiring so you can remember what wires go where, remove the old switch, and take it with you to the store. You will find a replacement.

Craftman air compressor pressure issue

It is a 20 gal 2hp it only has 100 psi how can i get it up to 120 psi?






Bill says...

Are you saying that the high pressure cut out is 100 PSI, and then the compressor stops?

Was this the setting that came with the compressor when you obtained it?

That being the case, the 100 PSI level is factory set, and your compressor is designed to have a 100 PSI maximum pressure. Trying to get that higher may reduce the life of your compressor.

If you need a compressor that delivers substantially higher pressure than the 100 PSI that you are getting from this one, my best advice is to get a properly sized compressor.

Cheers.

Bill
