Control Panel

Control Panel

The control panel contains the smart board, the touchscreen panel, and a three-button circuit board. Run the test for the control panel (see Control Performance Test). The control panel is replaced as an assembly.

Removal

Remove the hidden vent (see Microwave Removal and Component Access). Remove the grille. Lift up on the control panel and remove.

Disconnect 8 electrical connectors and the ground wire from the control panel.

Door Interlock Switches

The oven has 3 interlock switches. All switches are removed the same.

Door Sensing and Primary Interlock Switches

The primary interlock and monitor switches are located on the bottom of the plastic switch bracket. The power relay is mounted on the smart board. They 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. 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, primary interlock switch, and 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 door is opened.

Functions

When the door is opened, the monitor switch contact closes. At this time, the primary interlock switch and power relay are in the closed position.

As the door goes to a closed position, the monitor switch contacts are first opened and then the door sensing switch and the primary interlock switch contacts close.The oven has 3 interlock switches. All switches are removed the same.

Removal

Remove the hidden vent (see Microwave Removal and Component Access). Remove the grill. Lift up the control panel and remove.

Remove the 2 T20 Torx screws from the front of the frame and remove the door switch bracket.
