Wilbur D Gallatin , TN February 24, 2017 Appliance: Model GJC3034LQ0 ON THE USER MANUAL. The cooktop switch had failed due to poor engineering developement on how the switch was originally built to attach to the switch panel Within 6 months of use of the switch on the large dual element of the left front unit, the switch came loose from the mounting plate and would not allow the switch operation. It took me over 10 years to decide to fix it. The new switch was totally redesigned and was attached to the mounting plate directly with the small screws instead of using the mounting plate pressed onto small plastic horns on the switch, which ultimately failed when the user likely used too much downward pressure on the unit control knob when turning the unit on or off. The unit had to be completely lifted up and set on end from the cabinet cutout in order to remove all screws from around the unit enclosure. Then screws were removed from the front end panel to open the switch panel. Then the small screws holding the switch in place after removing all electrical connections followed by the reverse procedure on the new switch completed the repair, once the unit was reinstalled in the cabinet. The job takes about 2 hours and requires an electric Phillips screwdriver to save time.
