Hello, your Sears Kenmore central vacuum can be mended, though Sears doesn't produce it any longer. There is a troubleshooting guide for all central vacuums (since they operate in the same basic way) at www.builtinvacuum.com/flowchrt.html. Also there are replacement parts for the Kenmore at www.builtinvacuum.com/help/kenmore.html.
