FULL SIZE ELECTRIC CONVECTION OVEN - REMOVAL AND REPLACEMENT OF PARTS

3.Depress the retaining tabs and pull the socket out from the oven, far enough to disconnect the lead wires.

4.Remove the socket from the oven.

5.Attach the lead wires to the replacement socket.

6.Insert the socket into the hole in the oven and push until the socket is held in place by the retaining tabs.

7.Install the light bulb and lens.

COOLING FAN

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.

1.Remove the right side panel as outlined under

"COVERS AND PANELS".

NOTE: If right side panel is not accessible, this component can be serviced by removing the control panel as outlined under "COVERS AND PANELS".

2.Disconnect the lead wires to the fan motor by removing wire nuts.

3.Remove the screws securing the air deflector to the fan then loosen the tab screw holding the fan to the component panel. Rotate the tab so that the fan will clear and remove the fan.

4.Reverse the procedure to install the replacement fan and check for proper operation.

NOTE: The fan must be installed so air is pulled from outside the rear of the oven and blown into the control area. The arrow on the fan body indicates “air flow” direction and should be pointing toward the controls.

NOTE: Ensure fan is seated “squarely” against the air tube and the oven bottom.

NOTE: The air deflector should be angled upwards at approximately 30 degrees to properly direct the air flow.
