Why Does My Compressor Stop and Start Continuously?

You may be asking, why does my air compressor start, then stop? Allow us to take the guessing out of it. We understand your pain. We know that a compressor problem can quickly result in hours (if not days) of production downtime and loss of revenue. When your compressor continuously shuts off from on, we refer that as a short cycle. There are a few reasons that a short cycle may be happening with your compressor.

The reasons below are only for the compressors that have been working previously without issue and have no large changes have occurred in the placement or demand of the machine.

1.The number one reason for rapid cycling is inadequate air receiver capacity especially on smaller machines. The root cause can be as simple as the air receiver being full of condensate water because it has not been emptied. 

2. Pressure switch out of adjustment: Check the switch to see if you can remedy the sitation. This part will need to be replaced and is common wear and tear on a machine.

3. You've developed a leak: If the switch isn't the issue and the machines need haven't been changed, you most likely have developed a leak. Contact your closest service provider to help locate your air leak.

4. The machine may be undersized for the application: Understanding your businesses flow (CFM) and pressure (PSI) needs to accomplish the frequency of the job that has to be completed is the KEY to ensuring your compressor is the right size. Please contact a service professional to ensure this isn't the current problem you are experiencing.
