Gary E Smyrna , GA March 11, 2016 Appliance: Whirlpool 30" Gas Slide-In GW399LXUS05 Whirlpool Range Gw399lxus05: Certain buttons on touch pad membrane (timer most notably) failed. How to replace Range Touch Pad Membrane Switch. Replacing the switch membrane restored full function. Relatively easy. Had to pull stove out just a few inches to provide access to two side screws holding control enclosure. Then four screws on bottom edge just above oven door. Then a screw above each burner control. And one screw on the top edge at each corner (right screw additionally holding a ground wire). That allowed the structure to come out. Helper required to hold structure while I worked to unplug the old switch-membrane from circuit board and then peel it off front. Installed new switch-membrane by first plugging in its two cables, and then peeling adhesive backing off for adhering new switch-membrane to control surface. 16 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
