Door Interlock Switches

The door has 3 interlock switches. All switches are removed the same way.

Door Sensing and Primary Interlock Switches

The power relay is mounted on the smart board. The primary interlock and door sensing switches are activated by the latch heads on the door. When the door is opened, the switches interrupt the circuit to all components, except the oven lamp and the control panel display. A cook cycle cannot take place until the door is firmly closed, thereby activating both interlock switches. The primary interlock system consists of the door sensing switch, the primary interlock switch, and the power relay.

Monitor Switch

The monitor switch is operated indirectly by the bottom latch pawl. The pawl operates a cam switch, which in turn, activates the monitor switch. The switch is intended to render the oven inoperative by means of blowing the monitor fuse when the contacts of the primary interlock switch and power relay fail to open when the door is opened.

Functions

When the door is opened, the monitor switch is closed. At this time, the primary interlock switch and the power relay are open.

As the door goes to a closed position, the monitor switch is first open and then the door sensing switch and the primary interlock switch contacts close.

To remove the door interlock switches:

1. Disconnect wiring to the door switches.

3.Remove the 2 Phillips-head screws that attach the door switch bracket to the microwave oven frame and remove the door switch bracket.
