Craftsman pressure switch failure

by David
(Louisville, KY)

From what I read it sounds like my pressure switch has failed.


I turn it on it goes up to the pressure I have set but does not cut out. My question is this. I only used this compressor a few times before I realized it was not working (popped the safety valve). I am not sure why it went bad. It was basically brand new. Are there things that will cause a pressure switch to fail prematurely?

I have a Craftsman 30 gallon, vertical tank, model 916167600.

David, sure. Though they retail for $25-$30 for you to buy, I suspect that the compressor companies are paying just a couple of dollars for them. They are cheap pressure switches that are used on DIY type air compressors, and like all cheap equipment, are built using the least expensive components.

The only surprise is that they don't fail more often.

Specifically, you may have just got a dud. And you're right. It does sound like it's the pressure switch that has failed on your compressor. Time for a new one.

Cheers,

Bill

Require new tank original has rusted

You may find that a new tank will cost more than if you buy a new compressor with the same tank size, even if the new had a smaller pump.

It were me, I'd search for tank prices, new compressor prices, and if the new compressor price was within 25% of the compressor, I'd buy a new compressor and keep the parts off the old for spares for the new.

There are many after market tank suppliers available by searching on line.
