THE OVEN DOOR

37

The proper fit and adjustment of the oven door is essential for safe and reliable operation of the NGC (Tornado) oven.

The oven door provides three primary functions:

1.To protect the operator from the hot convection airflow.

2.To protect the operator from exposure to microwave energy.

3.To actuate the interlock switches.

REMOVING/REINSTALLING THE OVEN DOOR

To remove or reinstall the oven door, follow the steps below. Refer to Figure 26.

1.Ensure the oven has cooled.

2.Open the oven door to its full open position. Locate the two (2) thru holes in the bottom of the left and right hinge assemblies. Insert a screw or nail into the holes to keep the hinges open while removing the oven door.
