Air compressor wont shut off till 250 lbs
For model number D55146
Hi Mark,
Thank you for your question. If your compressor continues to build pressure and does not cut out at the recommended pressure, you may have a faulty pressure switch. The pressure switch is designed to shut down the compressor once it reaches the recommended PSI level. If the pressure switch is fine, there are some parts that you will need to check to see which one is causing the issue. You will need to check the intake valve, the pressure valve, the pump gaskets, the check valve, and the compressor. Once you have determined the part you need, please feel free to call customer service. We are open 7 days a week and anyone will be happy to assist you. We look forward to hearing from you!
