Why does my compressor keep stopping?

Why does my compressor keep stopping?

An air compressor problem could stem from one of many issues, such as an air leak, an oil leak or a broken part. In some cases, you might have insufficient pressurization or air flow. In other cases, the compressor might fail to start up or stop running as prompted.

At what pressure should the air compressor stop?

It is the compressor pressure switch that is supposed to shut the air compressor off when the tank pressure reaches the cut out pressure level. That pressure cut out level may be in the 100 PSI through to 175 PSI level, depending on the brand and size of your air compressor.

When should an air compressor shut off?

The compressor switch functions to turn off the air compressor when the tank pressure is already high and reaches the cut out pressure setting level. You should be familiar of the PSI of your air compressor. The common range is between 100 – 175 PSI.

When does an air compressor start and stop?

Air compressors like California Air Tools models start and stop continuously when their pressure differential gets to a slim margin of 1 bar (14 psi). The differential pressure of compression systems is the variation between the cut-in and the cut-out pressure. If your air compressor won’t reach pressure, the faulty switch needs a replacement.

What should the pressure be when an air compressor starts?

The range of pressure between the air compressor stopping and then starting is in the 20 – 30 PSI area. If your compressor stops at 120 PSI for example, it would typically start around the 90 PSI tank pressure level. Pair of typical pressure switches for different types of compressors.

Can a air compressor run for 100%?

Even smaller air compressors that claim a 100% duty cycle – and you might infer from that that you can run them continuously – are generally not supposed to run that long.

What to do if your air compressor won’t shut off?

If the compressor isn’t cycling on and off to fill the tank, replace the pressure switch. If your air compressor won’t shut off after reaching full cut-out pressure or won’t start again after tank pressure drops, the pressure switch might be the problem.
