Circuit Spring Unit - Kenmore Canister, 3-Prong T1400 Best for: carpet and mixedThe Circuit Spring Unit for Kenmore canister vacuums is a 3 prong electrical contact assembly that carries power through the hose and wand to the power nozzle. Electrified hose systems depend on these small metal contacts, and when they wear or lose spring tension, the power nozzle cuts out intermittently or stops receiving electricity altogether. If your brush roll only runs when the hose sits at a certain angle, this component is a likely culprit.
