3.When the door is opened during cooking.

•Primary interlock switch and secondary interlock switch open to cut off the primary voltage to the high voltage transformer to stop microwave oscillation.

•Fan motor, timer motor and turntable motor stop rotating.

•Oven lamp turn off.

•As soon as the door is opened, monitor switch close (NC) to create the short circuit.

If the contacts of primary interlock switch and secondary interlock switch are both malfunction, the 15A fuse blows open due to the large current surge caused by monitor switch activation.
