The center part of the (right front) dual element burner does not work, the outside ring is OK. How do I test to find if the problem is the selector rocker switch, burner, or the burner switch? Frigidaire Range Model - FEF369CGSD, Serial - VF01716433.
If the element works when the unit is set for the small element but is not working on the dual element setting then the issue would most likely be in the infinite switch. If the rocker switch was not working then the large element would not come on at all. If the center element does not work at all then you will need to look at the element to make sure that it is not burnt out.

You will need to pull unit from wall. Disconnect power from unit and remove the control panel rear cover. Once cover is removed you will remove knob from the front and take the 2 screws out holding the switch in place. Once out, one at a time transfer the wires from one switch to the other making sure you watch what terminal they came off of and put on the same on the new switch. Once all are transferred, screw new switch in place and install knob and rear cover. Plug unit in and slide back into position.
