Questions & Answers for Craftsman 921166400


Relief valve is bad.
George for model number 921166400 asked on 2023-04-07
Hi George, Thank you for writing. The Safety Valve for this model is Part Number: E102595. We hope this helps!

What procedure to use to determine if the Check Valve part # E101362 is functioning correctly? Compressor leaks air from the pressure switch part # E100957. (Pressure switch replaced on your order number 19686848.)
WL for model number 921.166400 asked on 2023-11-02
Hello WL, Thank you for reaching out. Detach the check valve from the unit, and wipe out any debris. Next, blow some air through the check valve on port 1. If it is working properly there should be no air passing through ports. I hope this helps and good luck with your repair.
