Next, I swapped the pressure switch out for a known good switch, thinking maybe a bad switch, but the same results. I then turned off the supply valve to the tank with the pump running, and it was the same as when the valve opened about 40 PSI.Faulty Intake Valve. A faulty intake valve is another reason for the slow build pressure of your compressor. A faulty intake valve is similar to a failing pump or fapper pressure valve. The compressor can not compress air with a faulty intake valve. The air enters the intake valve without a compressed process.11. Poor Air Quality: If you are noticing a decrease in air quality from your Ingersoll Rand 185 Air Compressor, check the air filters and replace them as necessary. 12. Pressure Builds Up Too Fast: This could be due to the pressure switch not being set correctly or something blocking the compressor’s airflow.Make sure to turn off the air compressor properly, and then you will have to drain the tank using that drainage valve. Once you ensure that the tank is empty, you will need to run the air compressor again and that is going to make it work for you for good. The air compressor is going to fill without any vacuums on it. 2) Leakages.Changing a pump pressure control switch from 20/40 all the way up to 40/60 has an understandable appeal: much higher water pressure, faster flow rate. But the risk is that you set a cut-off pressure that the pump simply cannot maintain. If that happens the pump might just keep on running - never reaching that 60 psi.3) Vacuum. The vacuum is another major concern on these tanks that come from the RIDGID Air Compressors. The Vacuum on these air compressors can cause you to have different issues with the pressure level on the air compressors and that is obviously something that you will never want to have.Drain the tank pressure to zero. Turn the compressor back on. If it doesn't start, put a meter on the line from the pressure switch to the motor and make sure power is flowing. If not, change the pressure switch. Take that one with you to the compressor store when you go to buy a new compressor pressure switch.freeing up stuck unloader valve on compressor. that caused the truck to not build air pressure.1.
