Hoover WindTunnel Control Cable Retainer Screw

Part 21751010 sits inside Hoover WindTunnel upright vacuums, holding the control cable tube in place. It is a small fastener doing a job that goes unnoticed until it is gone, and it is inexpensive enough to replace on sight once you have the machine open.

If this screw backs out or goes missing, the cable tube can shift out of position and the control it serves stops holding its setting reliably, which usually feels like slack or vagueness at the control rather than an outright failure. Fitting a new screw pulls the tube snugly back into place so the control works against something solid again.

It fits Hoover WindTunnel models including the U6423900, U6430900, U6435900, U6441900, U6450900, U6460900, U6470900, U6485100, U6607900, U6630900, U6660900, UH50000, UH60000 and UH60010.
