compressor is not stoping

[roger]

When the compressor start charging until 120 psi the motor
doesn't stop automatic, just continue working. What is wrong with it?

Hi Roger,

It sounds like you have a bad pressure switch. The pressure switch is the part that senses when the compressor has filled the tank to a certain pressure at which point it cuts the power to the motor. The pressure switch is part #A05802 and is available from http://ereplacementparts.com.

Good luck with your repair!
