60637 Pancake dead? Might be rectifier!

Compressor blew a fuse. found a replacement fuse (Home Depot but expensive-2 for $5) and it blew too.

Opened up the case and found nothing in the way of problems.

Opened the motor and found it's DC with a KBPC608 bridge rectifier tucked away inside where all the wires meet.

Suspect the rectifier is bad since there's nothing else that could short out. Brushes look fine as does the rest of the motor.

Rectifier is a $3 part but not available locally.

Hope this helps anyone else with problems with this model.

New rectifier didn't fix it!
by: Anonymous

An update on the rectifier repair: The part arrived on Friday and I installed it Saturday morning. Tried to run it and the fuse blew again so it appears to be a problem with the motor itself and not the rectifier.

Checked the rectifier
by: Anonymous


After posting the previous info I checked the rectifier with a VOM and 9v battery. It tests OK with the VOM and rectifies at 9 volts but may be breaking down at 120v. For laughs I tried powering the compressor with the 9v battery (the little, rectangular type used for small electronics) and the motor actually ran for a second or 2. Ordered a replacement rectifier and will let you know if it works.

Thank you for taking the time to let us know what you found.

When you get the replacement, could you let us know if it resolved the problem?
