AUTO WEIGHT DEFROST CYCLE
When auto defrost is selected and the desired defrosting time is chosen, the automatic cycle divides
the defrosting time into 5 periods of alternating defrost and stand times, by cycling on and off.
4. When the door is opened during cooking.
1) The primary interlock switch is opened to cut off primary voltage to the high voltage transformer
to stop microwave oscillation.
2) The secondary interlock switch is opened to give the door open information to touch control cir-
cuit. The contacts of the RELAY “1” and “2” open, the display stops counting down.
3) Fan motor and turn table motor stop rotating.
4) The oven lamp turns off.
5) As soon as the door is opened, the interlock monitor switch contacts close and creats the short
circuit.
6) If the contacts of primary interlock switch malfunction the 8A fuse blows open due to the large
current surge caused by the short circuit activation, and this in turn stops magnetron oscillation
(Fig. 1).
5. When the PAUSE/CLEAR pad is touched during cooking.
1) The touch control circuit cuts the voltage supplied to the RELAY “1” coil causing the magnetron
to stop oscillation.
2) The RELAY “2” turns off.
3) The display will show the time of day. If you didn’t set the clock, the display will show a colon.
4) The Oven lamp turns off.
5) Fan motor and turn table motor stop rotating.
