Abstract
A laundry machine having a malfunction detection system for detecting when an obstructing item protrudes outwardly from a perforated tumbler of the machine beyond a predetermined amount during rotation of the tumbler and for detecting when the drive belt for the tumbler is either broken or dislodged from its drive pulleys. In response to either malfunction, a control device is actuated for automatically shutting down operation of the machine. The obstruction detection system includes a cable disposed in closely spaced relation to an outer perimeter of the tumbler for engagement by an obstructing item extending outwardly from the perforated tumbler beyond the predetermined spacing of the cables. In the illustrated embodiment, the obstruction detection system and the drive belt malfunction detection system utilize a common malfunction detection switch and control circuitry.
