Important Safety Instructions
!
CAUTION
11. Use only popcorn in packages designed and
labeled for microwave use. Pop according to
package directions, beginning with the
minimum amount of time recommended.
Use caution when handling hot popcorn bag.
12. Microwave convenience foods are often
packaged in specially designed packaging.
Special plates, lids, containers, or other
unique packaging materials may be used.
Susceptor packing material (a thin, metalized
plastic film) is frequently used to help brown
and make crisp foods such as microwave pizzas,
French fries, or fish sticks. Be sure to follow
food package instructions carefully. Contact
convenience food manufacturer with
questions concerning these products. Amana
does not endorse any brand of microwave
convenience foods, or any type of microwave
food packaging.
13. Do not operate microwave oven empty. This
could damage the oven.
14. Do not use regular cooking thermometers in
oven. Most cooking thermometers contain
mercury and may cause “arcing”, malfunction,
and/or damage to oven.
15. Metal or ceramic accessories which are
designed to absorb microwave energy to
provide heat should be used with caution. Test
device before use. Read and follow
manufacturer's instructions provided with the
accessory. Contact accessory manufacturer
with questions concerning these accessories.
Amana does not endorse any brand of
accessory.
16. Do not use paper products not intended for
cooking when oven is operated in convection or
combination mode.
17. Pierce or open plastic bags (and other airtight
containers) before heating in microwave oven.
This allows steam to escape during cooking.
18. Containers may become hot and pot holders may
be needed.
19. Closely supervise any use by children. Make
sure they can read instructions and reach
controls. Never allow them to lean or swing on
oven door.
To avoid personal injury or property damage observe
the following:
1. Always press STOP/RESET before programming
oven.
2. Do not deep fat fry in oven. Fat could overheat
and be hazardous to handle.
3. Do not cook or reheat eggs in shell or with an
unbroken yolk. Pressure may build up and
erupt. Pierce yolk with a fork or knife before
cooking. Do not reheat previously cooked eggs
in the microwave oven unless finely chopped or
scrambled.
4. Pierce skin of potatoes, tomatoes, or other foods
with a "skin" before cooking in microwave oven.
Piercing skin allows steam to escape during
cooking.
5. Do not home can in microwave oven. Home
canning is generally done with metal lids. Since
metal lids reflect heat, product may not be heated
uniformly to 212°F or above. Food could
deteriorate. USDA extension specialists do not
recommend home canning in microwave ovens.
6. Remove excess fat from meats and poultry to
prevent splattering.
7. Do not heat baby bottles in microwave oven.
8. Briskly stir or pour liquids before heating to
prevent spontaneous boiling or eruption. Do
not overheat. If air is not mixed into a liquid,
liquid can erupt in oven or after removal from
oven.
9. All uncooked foods should be heated to a final
internal temperature of at least 165°F. Some
foods require higher temperatures. These
recommended temperatures kill most food borne,
disease causing organisms. Some common
visual signs that indicate the cooking temperature
has been reached:
• Food steams throughout, not just around
edges.
• Center bottom of dish is very hot to the
touch.
10. If using a microwave popcorn popper, use
according to manufacturer's instructions. Do not
continue to heat after popping has stopped.
Popcorn will scorch or burn. Do not leave oven
unattended.

Microwave Energy Leakage Testing
!
Measurement With the Outer Case
Removed
WARNING
Check for radiation leakage after servicing. Should the
leakage be more than 4mW/cm2 inform Amana
immediately. After repairing or replacing any radiation
safety device, keep a written record for future
reference, as required by D.H.H.S. and HEW
regulations. This requirement must be strictly
observed. In addition, the leakage reading must be
recorded on the service repair ticket while at the
customer’s location.
!
DANGER
To avoid risk of personal injury or death avoid
contacting any high voltage components.
Whenever you replace the magnetron, measure for
radiation leakage before the outer case is installed and
after all necessary components are replaced or
adjusted. Special care should be taken in measuring
around the magnetron.
Equipment
Measurement With a Fully Assembled Oven
• Electromagnetic radiation monitor
• 600 cc glass beaker
After all components, including the outer panel are fully
assembled, measure for radiation leakage around the
door periphery, the door viewing window, the exhaust
opening, and air inlet openings.
Procedure For Measuring Radiation
Leakage
Note before measuring -
Record Keeping and Notification After
Measurement
• Do not exceed meter full scale deflection. Leak
monitor should initially be set to the highest scale.
• To prevent false readings the test probe should be
held by the grip portion of the handle only.
• The scan speed is equal to one inch per antenna
revolution or one inch per second if antenna speed is
unknown.
• Areas to be checked are all door seal areas and any
venting parts.
• Leakage with the outer panel removed . . . 4mW/cm2
or less.
• Leakage for fully assembled oven with door normally
closed . . . 4mW/cm2 or less.
• Leakage for a fully assembly oven (before the latch
switch (primary) is interrupted) while pulling the door
... 4mW/cm2 or less.
1. After any adjustment or repair to a microwave oven,
a leakage reading must be taken. Record this
leakage reading on the repair ticket even if it is zero.
2. A copy of the repair ticket and the microwave
leakage reading should be kept by the repair facility.
1. Open the oven door and verify that there is only one
rack in place on the bottom rack hooks.
2 . Pour 275 ± 15 cc (9 oz ± 1/2 oz) of 20 ± 5°C
(68± 9°F) water in a glass beaker which is graduated
to 600 cc and place the beaker in the center of rack.
3. Set the radiation monitor to 2450 MHz and use it
following the manufacturer’s recommended test
procedure to assure correct results.
4. While measuring the leakage, always use the two
inch (5 cm) spacer supplied with the probe.
5. Press the start pad or turn on the timer and with the
magnetron oscillating, measure the leakage by
holding the probe perpendicular to the surface being
measured.

Troubleshooting Procedures
!
CAUTION
To avoid electrical shock, personal injury, or death, disconnect power to unit before servicing, unless testing
requires power.
CAUTIONS
1. Check grounding before checking for trouble.
2. Be careful of the high voltage circuit.
3. Discharge the high voltage capacitor.
4. When checking the continuity of the switches or of the high voltage transformer, disconnect one lead wire
from these parts and then check continuity with the AC plug removed. To do otherwise may result in a
false reading or damage to your meter.
5. Do not touch any part of the circuit on the P.C.B. since static electric discharge may damage this control
panel.
Always touch yourself to ground while working on this panel to discharge any static charge built up in your
body.

Cooking Methods
Microwave Cooking
Microwave cooking uses high frequency energy waves to heat the food.
When cooking, microwave energy causes food molecules to move rapidly.
This rapid movement between the food molecules creates heat, which cooks
the food. Microwaves cook moist food and foods of varying fat content more
quickly.
Convection Cooking
Convection cooking utilizes both a convection element and fan to evenly
distribute heated air throughout the oven cavity. By circulating air, no hot or
cold spots occur, creating a consistent temperature envelope around the
food. These consistent temperatures cook food evenly and reduces cooking
time. Oven will always operate in convection mode.
Combination Cooking
The combination mode uses both the speed of microwave energy and
browning of convection cooking to yield fast, high quality food.
•
Microwave cooking uses high frequency energy waves to heat the food.
When cooking, microwave energy causes food molecules to move
rapidly. This rapid movement between the food molecules creates heat,
which cooks the food.
•
Convection cooking uses the selected oven temperature to bake and
brown foods. The circulating air surrounds food in an envelope of evenly
heated air.

Cookware Suggestions
What Should You Consider in Cookware?
Cooking method used determines the cookware that can be used. To simplify choices, use
cookware that is approved for all three cooking methods: microwave, convection and
combination.
Select
Avoid
Heat resistant glass
Non-heat resistant glass
Ceramics or china
Metal trimmed ceramics or china
Pyrex
Metal cookware
Heat resistant Teflon utensils, such as
spatulas.
Metal cooking utensils.
Microwave cookware that is safe to
450•F
Paper products, straw, wicker and wood.
. Handles that are secure.
Cookware with loose or broken handles.
Do not use metal utensils or pots in the oven.
Cooking hints for your oven
Covering
A cover will trap heat and steam, causing food to heat more quickly.
Always use a lid approved for both convection and microwave cooking.
Stirring
Redistributes heat in foods. Always stir from the outside toward the
center of the dish.
Piercing
Pierce the shell, skin or membrane of foods before heating to prevent
bursting.
Turning
Large foods should be turned so that the top and bottom heat evenly.
Arrangement
Do not stack food. Arrange in a single layer on a dish safe for
combination heating. .
Standing
Time
Foods often need to stand from 2 to 15 minutes after being removed
from the oven. This finishes cooking. Normally an internal temperature
will continue to rise approximately 5 to 10°F during standing time.
Spacing
Arrange individual foods, such as potatoes, in a circle and at least
1 inch apart. This helps food heat more evenly.
