AUTO 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 second interlock switch is opened to give the door open information to touch control circuit. The
contacts of the RELAY "1" and "2" open, the display stops counting down.
3) Fan motor and turn table stop rotating.
4) The oven lamp turns off.
5) The soon as the door is opened, the interlock monitor switch contacts close and create the short circuit.
6) If the contacts of primary interlock switch malfunction the 15A fuse blows open due to the large current
surge caused by the short circuit activation, and this in turn stops magnetron oscillation (Fig. 2).
5. When the STOP/CLEAR pad is touched during cooking.
1) The touch control circuit cuts the voltage supplied to the RELAY "1" coil and causes the magnetron to
stop oscillating.
2) RELAY "2" turns off.
3) The display will show the time of day.
4) The oven lamp turns off.
5) Fan motor and turn table motor stop rotating.
