First, locate the air pressure regulator. Is there other way to test the capacitor other then measuring the resistance like i did? Here are a few things to check: 1. The compressor thermal overload reset, also commonly referred to as a thermal cut-out, thermal overload, or safety switch, is there to automatically turn off the air compressors power when it overheats. Others are auto-reset types, which automatically let the motor restart when it has cooled enough. Once you have located the reset button, simply push it in and then release it. -Wire strippers And yes, unfortunately HFT is not very good about spares, like most sellers. Another common problem that can occur with pneumatic air compressors is overheating. If the discharge valve is closed, the compressor should build pressure. 2. This is a very common issue.

Do not use multi-viscosity oil (suchas 10W-30), they leave carbon deposits on pumpcomponents and lead to accelerated failure. The centrifugal switch can stick which will keep the start windings energized tripping the thermal switch. Check the valves of your air compressor, there might be some oil leakage and if that is the case, the tank of your compressor will take longer to fill and if it gets filled the reset button will trip and the motors get overheated.. 4. If your air compressor isnt building pressure, there are a few potential causes. I know it isnt the pressure switch, as it will do it at any pressure level, and if I bypass the pressure switch, it still cuts out below the specified 125 psi.

Ignoring problems can lead to further damage and a loss of performance. Leave the compressor to cool for 15 minutes or so, and then try plugging the air compressor power cord directly into a wall socket, preferably one that has a 20 amp breaker, and has no other electrical devices using power at the same time as the air compressor is trying to start.
