An air compressor typically shuts down when the tank reaches its maximum pressure to prevent over-pressurization, which can be dangerous. Additionally, compressors are often equipped with pressure switches that automatically stop the motor when the desired pressure level is reached, ensuring safe operation and energy efficiency. Once the air is discharged and pressure drops, the compressor will restart to replenish the air in the tank.

What is wrong with a compressor that will only air up to 60 psi and not shut off?

I had the same problem but the compressor would shut down from over heating. It turned out to be the pressure relief valve leaking. Listen for leaks. I ordered a new valve but never installed it because it turned out that mine was just stuck. Once I freed it, it has worked fine since. Also : The compressor is not shutting off because it is not reaching the shut off pressure. Check for air leaks. If it will not develope more than 60 psi, it may be worn out.


Why is your head pressure on your chiller getting so high it kicks out the compressor?

High head pressure on a chiller can be caused by several factors, including refrigerant overcharge, restricted airflow across the condenser coils, or high ambient temperatures affecting the cooling efficiency. It may also result from a malfunctioning expansion valve or insufficient refrigerant flow. When head pressure exceeds the compressor's designed limits, it triggers safety mechanisms that shut down the compressor to prevent damage. Regular maintenance and monitoring are essential to identify and resolve these issues promptly.

What is a non-positive shut off valve?

A non-positive shut off valve is one that is controlled by the user. You hold down the valve to keep the water or whatever coming out, and when you want it to stop, you release the valve.

What is wrong if your AC blows cool for about a minute and then the outside shuts off and the fan just blows hot air?

It could be any one of the following: 1. The fan motor is overheating and is shutting down on overload, which will cause the compressor to shut down via the high pressure switch. 2. The compressor is getting too hot and is shutting down via the thermal overload switch. You need to determine if the fan and the compressor both come on at the outdoor unit. If you are getting cold air inside the house, the compressor is probably running. It generally takes longer than 1 minute for the fan to go out on overload unless the bearings are shot, then the fan motor could seize up and shut the compressor down on overload. You should have this checked by an HVAC tech.
