Thomas L Trophy Club , TX October 19, 2018 My wife dropped a bottle of bleach on the temperature control knob of my dryer and broke the shaft. Had to replace the switch and the knob. Pulled the panel off, replaced the switch. The knob itself had an insert clip in it already, so I bought an extra one for nothing. Job complete dryer works perfect again.
