Defrosting Tips & Techniques
Preparation For Freezing:
1. Freeze meats, poultry, and fish in packages with only 1 or 2 layers of food. Place 
wax paper between layers.
2. Package in heavy-duty plastic wraps, bags (labeled “For Freezer”), or freezer paper.
3. Remove as much air as possible.
4. Seal securely, date, and label.
To Defrost:
1. Remove wrapper. This helps moisture to evaporate. Juices from food can get hot and 
cook the food. 
2. Set food in microwave safe dish. 
3. Place roasts fat-side down. Place whole poultry breast-side down.
4. Select power and minimum time so that items will be under-defrosted.
5. Drain liquids during defrosting.
6. Turn over (invert) items during defrosting.
7. Shield edges and ends if needed. (See Cooking Techniques).
After Defrosting:
1. Large items may be icy in the center. Defrosting will complete during STANDING TIME.
2. Let stand, covered, following stand time directions on page 14.
3. Rinse foods indicated in the chart.
4. Items which have been layered should be rinsed separately or have a longer stand time.

FeatureSensor Cook    
Feature
NOTE:
Casseroles- Add 3 to 4 tablespoons of liquid,
cover with lid or vented plastic wrap. Stir when
time appears in the display window.
Canned foods- Empty contents into casse-
role dish or serving bowl, cover dish with lid or
vented plastic wrap. After reheating, let stand
for a few minutes.
Plate of food- Arrange food on plate; top with
butter, gravy, etc. Cover with lid or vented
plastic wrap. After reheating, let stand for a
few minutes.
DO NOT USE SENSOR REHEAT:
1. To reheat bread and pastry products. Use
manual power and time for these foods.
2. For raw or uncooked foods.
3. If oven cavity is warm.
4. For beverages.
5. For frozen foods.
This sensor feature allows you to reheat
cooked, refrigerated food without setting
time. The oven simplifies programming.
This sensor feature allows you to cook
food without setting time. The oven sim-
plifies programming.
BEFOREReheating/Cooking:
1. The room temperature surrounding the
oven should be below 95° F (35° C).
2. Food weight should exceed 4 oz. (110 g).
3. Be sure the glass tray, the outside of the
cooking containers and the inside of the
microwave oven are dry before placing
food in the oven. Residual beads of mois-
ture turning into steam can mislead the
sensor.
4. Cover food with lid, or with vented plastic
wrap. Never use tightly sealed plastic
containers—they can prevent steam from
escaping and cause food to overcook.
DURINGReheating/Cooking:
DO NOT open the oven door until 2 beeps
sound and cooking time appears on the
Display Window.  Doing so will cause inac-
curate cooking since the steam from food is
no longer contained within the oven cavity.
Once the cooking time begins to count
down, the oven door may be opened to stir,
turn, or rearrange foods.
AFTERReheating/Cooking:
All foods should have a stand time.
Example: To reheat a plate of food 
1.• Press Sensor Reheat.
