Hi Arthur, Thank you for your question. If your air compressor will not come on, make sure that the air compressor is plugged directly into an electrical outlet. If it is plugged into an extension cord, it will not work correctly. Check and see if the circuit breaker has been tripped and replace the fuses if they have blown. You will also need to check the pressure switch. If you have too much or too little pressure, the pressure switch may be faulty. You should also check the gaskets, seals and valves to make sure that there are no leaks coming from them. If there are leaks coming from them, they will need to be replaced. You should also check the pressure reducer and the power cord. We hope this helps with the repair!

Hello Thomas, Thank you for your inquiry. The purpose of the Valve Plate is to allow air into the cylinder. Once the piston starts traveling up the reeds on the Valve Plate open and air is sent into the air tank, so it can be one of the causes for the compressor not building pressure. We also recommend checking the pressure reducer, the safety valve, and the pressure switch. We hope this helps and if you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!
