Hi, if my air compressor is going past the 200 psi max tank pressure and blowing off PRV do I need a new pressure switch?
For model number D55146/A18491
Fix.com logo
Hi Seth, thank you for reaching out. The issue is probably with the pressure switch, part number FIX12092984. But before replacing the pressure switch, we suggest checking the regulator assembly, part number FIX10187318, and the safety valve, part number FIX10116464. We hope this sorts out your problem!

Compressor would not run
Very simple. Took photos of the electrical hookups prior to removing the old pressure switch via mobile phone. Removed old pressure switch and then removed the safety valve and pressure meter from old switch and put them on the new pressure switch (teflon tape required). Put new switch on and added the electrical hookups. Job done. T his fixed my issue.
