This hole cover is almost two inches in diameter. It fits below the surface burner knob of some ranges, and has a center hole just big enough for the knob's shaft.
Turned off power to unit. Tilted up Glass top and removed two screws holding rear hinges to range. Then I unplugged wire harness from lower range and placed the Glass top facing down on counter top with towel for cushion. Removed 1 screw holding center of burner to support frame, two alignment screws on perimeter, and two screws holding support frame to glass top. This allowed me to slide out the old element with all wiring connections intact. Placed the new assembly in same location under support frame, noting numbered positions of two alignment screws from old unit. This is necessary to properly align heater to surface glass. Replaced all screws connecting burner to frame. Then I removed each wire one-by-one from old unit, reconnecting to same location on new unit.
Replaced top in reverse order from removal. Powered on the circuit breaker and verified proper operation of dual unit with large/small selecttor switch. Total time to repair about 30 minutes.
1. Open the circuit breaker feeding the range. Turn all range control switches ON to establish that there is no power. Remove all knobs. 2. Get under the range and remove the 2 hex-head screws securing the flex conduit to the bottom panel. Then remove the 20 hex-head screws securing the panel to the range. Lower the panel and place aside, and then after checking for no voltage disconnect the red and black incoming wires by pulling on the spade connectors. Make sure you mark which wire went where. 3. From below apply pressure to the range frame to free the top surface gasket from collected food debris, then from above lift our the range and place upside down on a towel. Support the range with wooden blocks so that the unit is not resting on the knob shafts. 4. The control switches are all mounted on a common bracket with two screws for each switch. The first task is to remove two screws on each side holding the bracket to the frame, and then two wire harnesses on each side. Then gently move the bracket and rotate it sidewards so you have access to the screws holding down the switches. 5. Remove the defective switch leaving all the wires still connected. 6. Install the new switch and transfer the wires from the defective switch. 7. You're done, now restore everything in reverse, just make sure all wires move freely and not pinched.
