Pressure switch not shuting motor off - Coleman Powermate 27 Gallon Air Compressor

I believe an A15332 is a pressure switch? If the air compressor is building pressure, then shuting down. It should restart as soon as the pressure switch activates. The pressure switch should do this once the pressure is low enough. It helps to know at what pressures the switch is supposed to open and close. For example 100-125psi. It should stop the air compressor at 125 psi and restart it once the pressure falls to 100psi. If the pressure switch is wired correctly and it's not starting the machine at the rated pressure setting, the switch is bad. Because you have already replaced the pressure switch, I would confirm the wiring. Then the pressure setting. Replace the switch if necessary.

It could be Low on Freon and going OFF on low pressure switch.......
Or it could be a dirty condensor coil or a Condensor Fan Motor not running and going OFF on High pressure switch....

Or if you are running the RTU in Low Ambient Conditions like 50* to 60* degrees Outside the Condensor Fan Motors could be cycling on a Fan Cycling Control....which is normal operation

So it could be any one of these or something different I would need to know what you are talking
about what is cycling??? Fan, Compressor , blower motor, whole unit shuting down, etc.

replace regulator

Hello,Sounds like it is overheating due to restricted flow.If it is shuting down due to pressure.Maybe high limit?If it is oil fired try reducing the nozzle size/input.If gas you could reduce input pressure 1"WC.

check plastic hose out side of tub to pressure switch
if ok replace pressure switch

I have had this when the gas pressure is marginal and as soon as the pump compresses some gas the pressure drops and the switch cuts out, the cycle then repeats. Usually the switch is in the aluminum pipe towards the bulkhead.

Hi,
There are 4 common trouble makers to consider.
One is the switches; it can open circuit and stop the washer. For some reason Maytag has seen fit to discontinue the lock and latch as a complete assembly and will only sell it as individual parts new.
Second is water pressure. If the water pressure is low/poor, the washer will start to fill and then shut off. Check and clean the fill valve entrance screens and also check for any washer screens on either end of the fill hoses. There is a low water pressure fill jumper kit assembly part# 12001482.
The third is possibly the most common trouble maker for this type of a complaint. The fuse blows on the motor control board. This board can be found on the front bottom on the right side. Take apart info. The motor control board must be replaced when the fuse has blown. Most times now the motor control board is replaced with a motor kit - the motor kit Motor/control conversion kit.
The fourth is a bad start switch, sometimes the contacts in the start switch will arc and burn causing starting up problems.

Thank You for contacting Fixya.com

The best thing to do is make sure the freon level is good ,if that ok then ckeck the pressure with a set of a/c gages if the high side pressure are lower than 350psi and the low side is higher than 35psi and the compressor is shuting off the low pressure switch is bad.

This was poorly designed , you will have more problems unless you fix it right as the bolt heads underneath the shute ring is rubbing the right stop and on top of the motor housing the main problem is the left ring stop is hanging up on the front motor mount.
to fix it,remove the motor,grind about 3/16" off the rear shims and file about the same off the bottom of the front motor mount,remove the motor mount bracket,file about 1/4" off of the right stop,remove the shute and the shute ring, mark the left stop before removing,bend the left stop up about 3/16" be careful not to bend the ring,replace motor bracket first than shute ring and shute than replace motor.if your shute has hung up often you may need to replace the motor,you can go to an auto parts store buy a 1999 chevy lumnia passenger side window motor around $50.00 vs yardman $360.00 you will need to tap out the mount holes with a 5/16 standard thread tap and tap from the bottom of the motor,don't forget to file the bottom of front motor mount.

fan relay bad...fan motor assembly bad or bad ac pressure switch
