Unpluged unit from receptacle. Simply slid the unit forward a bit (to get to screws after removing face), removed four screws, pulled the wired sensor from front of grill. Reversed & replaced everything, plugged unit back in and turned on - all working well. Easy job.
Removed the back - Saw the broken clips on the base of the dryer (the wires to the motor were pulling out because the motor was slipping).
Guessed that the parts were motor clips (no pix in the web site!)
Got the parts in post - they were identical except needed some rubber grips inside to hold tight (Used pieces of bike tire inner tube cut to fit for this.) Attached clips. Works fine!!
