Defrosting

The Auto Defrost feature’s preset programs can be used or the 
microwave oven can be manually set to defrost. 

Unwrap foods and remove lids (for example, from fruit juice 
containers) before defrosting.

Shallow packages will defrost more quickly than deep blocks.

Separate food pieces as soon as possible during or at the 
end of the cycle for more even defrosting.

Use small pieces of aluminum foil to shield parts of food such 
as chicken wings, leg tips and fish tails. See “Aluminum Foil 
and Metal” first.

The Auto Defrost feature has preset times and cook powers for 
3 categories: Meat, Poultry and Fish. It should not be used for 
food that has been left outside the freezer for more than 
20 minutes, or for frozen ready-made food. Use the following 
chart as a guide.

To Use Auto Defrost:

1.

Place food, uncovered, on the turntable and close the door.

2.

Touch AUTO DEFROST.

The display will show the setting for defrosting Meat. Touch 
AUTO DEFROST a second time for the Poultry setting, and a 
third time for the Fish setting.

3.

Enter the weight. 

Weight can be set from 0.1 lb to 6.0 lbs (45 g to 2.7 kg).

4.

Touch START.

The display will count down the defrost time.

During defrosting, 5 short tones will sound. These tones 
indicate it is time to check, turn, rearrange, or separate food. 
Open door, turn food if necessary, close door, and touch 
START to resume defrosting.

When the cycle ends, “END” will appear in the display, and 
the end-of-cycle tones will sound, followed by reminder 
tones.

5.

Touch OFF-CANCEL or open the door to clear the display 
and/or stop reminder tones.

To Defrost Manually:

 Follow direction in “Manual Cooking” 

section, and use 30% cooking power. See “Microwave Cooking 
Power” chart.

Warm Hold

Hot cooked food can be kept warm in the microwave oven. The 
Warm Hold function uses 10% cook power. Warm Hold can be 
used by itself or can be programmed to follow a cooking cycle. 
Opening the door during Warm Hold will cancel the function.

Cover plates of food.

Cover foods that were covered while being cooked.

For best results, do not cover baked goods such as pastries, 
pies, turnovers, etc.

To Use (for single cycle):

1.

Place hot cooked food on the turntable, and close the door.

2.

Touch WARM HOLD.

3.

Touch START.

“WARM” will appear in the display during the entire cycle.

When the cycle ends, “END” will appear in the display, and 
the end-of-cycle tones will sound, followed by reminder 
tones.

4.

Touch CANCEL or open the door to clear the display and/or 
stop reminder tones.

To Set at end of cycle: 

Touch WARM HOLD while setting a 

cooking cycle before touching START, or during cooking.
