My compressor will fill up but then it will not turn on when the pressure drops. If I unplug it and wait a while it will start up . I'm guessing it's overheating but I don't know why
Mark For model number Btfp020212 - November 8, 2023

Hello Mark, Thank you for your inquiry. It sounds more like an issue with the pressure switch, part# N003307SV. We would also recommend checking the safety valve and manifold. Good luck with your repair.

My compressor doesn't shut off when it gets up to the set pressure. It continues until it reaches total pressure and blows the relief valve. What part would I need to fix that?

I watched the video on website and followed the directions to replace the pressure switch. It was relatively easy to understand although there are a number of steps involved. After the repair the compressor worked properly. I don\'t think I would have been able to complete the repair based on the written instructions packed with the r eplacement pressure switch. I copied the link to the video.

The included repair instructions were very accurate and helpful. Make sure the compressor is fully empty before starting by opening the valve on the compressor tank bottom. Use a diagonal cutter to cut and remove the hose clamp were attached to the regulator assembly. Follow the instructions on removal of all screws. Remove the cover and carefully remove the compressor motor assembly.Remove the two leads on the old pressure switch one from the on/off switch and the other on the motor assembly. Remove the old switch. Reverse the whole procedure to install the new switch. Make sure you close the tank valve and carefully squeeze the hose clamp with the nail nipper. Compressor is back in action!
