Harry, what housing is the air blowing out of? Are you saying that the compressed air from the tank is blowing out of the pressure switch housing?

If that is your thought, visit the site map, and look at the page Pressure switch (Common Problems). Have a read of that please, to see if that helps.

Also, please post more details of your compressor as a comment here.

Thanks,

Bill

My brothertook my pressure switch apart, and I can't get it back together!!

Hey there, Great site. Ok, I have a Central Pneumatic 47065, 21 Gallon Compressor - and it was running with direct power (plug it in to run) until Little brother tried to 'fix it'.

I've got the basics on how it works down, but there's a v-shaped spring that I can't seem to figure out where it goes.

James, sorry about the switch.

I'm no switch specialist. If the reason for taking the switch apart was to fix it, (why else?) then if it were me, I'd buy a new one to replace the old. They are too important to the safe running of your compressor to fool around with.

If anyone else can tell James where to put his spring (be nice!) please chime in.

Cheers,

Bill

my air compressor shuts off at 80% instead of going all the way to 100%

Amanda, the device that turns the air compressor on and off is the pressure switch.

Can you tell from looking at the pressure switch on your compressor if it is tripping off when the air compressor stops?

Or, can you put a multi-meter on the power line from the switch to the motor after the compressor shuts off, to see if the compressor is off even when power is flowing through the switch to the motor.

I am thinking it is your pressure switch that has the problem, but more diagnostics are necessary to be sure.

Cheers,

Bill
