– 36 –Convection Bake Element andFan AssemblyFor more even baking, the new convection fanrotates in both directions depending on mode (seetable).The convection bake element and fan assemblyare located on the back wall of the oven linerbehind the panel with the screen in the center.To access convection bake element:1. Disconnect the power to range; remove theoven door and the oven racks.2. Remove 4 screws from the mounting panel (2on each side) and pull forward.Assumptions :1. Checked relays are providing corrected voltageoutputs.2. Control Compartment connectors are connected properly.3. Capacitor will fail as an open or short.Point 1 CW WindingsPoint 2 CCW WindingsPoint 3 Conv Fan NeutralNo Power Applied Measure ResistancePossible Failure Modes Pt 1 to 3 Pt 2 to 3 Pt 1 to 2Conv.
