The following pictures are steps for component removal. Make sure that the unit is unplugged or the circuit breaker is
in the off position.
Inntate Switch
Remove knob by simply pulling.
In the next step, remove the back top portion of the rear cover. Then remove the 2 screw holding the switch in place to
the user interface

16
Oven Temperature Sensor
Remove the lower portion of the rear panel of the unit. Disconnect the temperature sensor probe.
From inside the unit, remove the 2 T-20 Torx screws and remove the temperature probe.
Technical Details

17
Convection Element and Fan Motor
Remove the lower portion of the rear panel of the unit. Disconnect wires from the element and the fan motor.
From inside the unit, remove the 4 T-20 Torx screws to the convection cover. The nut on the blad is reverse threaded
and the fan blade must be removed to pull the motor from the rear.
Remove the 2 T-20 Torx screws to the convection element. To remove the motor, remove the 3 T-20 Torx screws and
the fan blade then pull motor from the back of the unit.

Broil Element
Remove the lower portion of the rear panel of the unit. Disconnect wires from the element.
From inside the unit, remove the 4 T-20 Torx screws holding the element in place, and pull unit out from front.
Bake Element
Remove the lower portion of the rear panel of the unit. Remove the power cover and disconnect the power wires.
Technical Details

19
Disconnect the wires to the the element and the 3 T-20 Torx fpr the shield for the bake element and the 2 T-20 Torx for
the element.
The bake element has 2 hooks on the front, so push the element forward and tilt front of the element upward and pull
the element out the rear of the unit. Extra insulation may need to be trimmed when reinstalling the element.
Technical Details

20
User Interface and Glass Top
Remove the upper portion of the rear panel of the unit. Disconnect wires from the control board and innate switches.
