Basicdesignofthismicrowaveovenmakesitaninherently
safe device to both use and service. However, there are
some precautions which should be followed when servic-
ing microwave oven to maintain this safety. These are as
follows:
1. Always operate unit from an adequately earthed
outlet. Do not operate on a two-wire extension cord.
2. Before servicing unit (if unit is operable) perform
microwave leakage test.
3. Oven should never be operated if door does not fit
properly against seal, hinge/hinge bearings are
damaged or broken; choke is damaged, (pieces
missing, etc.); or any other visible damage can be
noted. Check choke area to ensure that this area is
clean and free of all foreign matter. If any above
problems occur take the following steps:
• Tell the user not to operate the oven.
• Contact Amana immediately.
4. If oven operates with door open and produces
microwave energy, take the following steps:
• Tell the user not to operate the oven.
• Contact Amana immediately.
5. Always have power disconnected when outer case is
removed except when making "live" tests called for
in this manual. Do not reach into equipment area

Installation External Equipotential Earthing Terminal
Equipment has secondary earthing terminal. Terminal
provides external earthing connection used in addition to
earthing prong on plug. Located on outside of oven
back, terminal is marked with symbol shown below.
Earthing Instructions
NOTE: Do not under any circumstances cut or remove
earthing prong from the plug or bend power
prongs to fit receptacle other than one shown for
your equipment. Such abuse of the plug can
result in electrical shock or overheating.
WARNING
!
Improper use of earthing plug can result in a risk of
electrical shock or death.
Thisequipment MUST beearthed. In the event ofan
electrical short circuit, earthing reduces risk of electric
shock by providing an escape wire for electric current.
Thisoven isequipped witha cordhaving earthingwire
with a earthing plug. Plug must be plugged into an outlet
that is properly installed and earthed. DO NOT use a two-
prongadapter.
Consulta qualified electricianor servicerif earthing
instructions are not completely understood, or if doubt
exists as to whether the equipment is properly earthed.
Do not use an extension cord. If product power cord is
too short, have a qualified electrician install an
appropriatereceptacle. Thisequipment shouldbe
plugged into a separate 50 Hz circuit with the appropriate
electrical rating as shown in the drawings. When an oven
is on a circuit with other equipment, an increase in
cooking times may be required and fuses can be blown.
Unpacking Equipment
• Inspect equipment for damage such as dents in door
or dents inside oven cavity.
• Report any dents or breakage to source of purchase
immediately. Do not attempt to use oven if damaged.
• Remove all materials from oven interior.
• If oven has been stored in extremely cold area, wait a
few hours before connecting power.
Equipment Placement
• Allow at least 7 inches/ 17.8 centemeters of clearance
aroundtop and sidesof equipment.Proper airflow
around equipment cools electrical components. With
restrictedair flow, oven may not operateproperly and
life of electrical parts is reduced.
• Allow at least 2-9/16 inches/ 6.5 centimeters between
back of oven and rear wall.
• Do not install equipment next to or above source of
heat, such as pizza oven or deep fat fryer. This could
cause microwave oven to operate improperly and
could shorten life of electrical parts.
• Do not block or obstruct oven filter.
• Allow access for cleaning.

Microwave Power Test
(TRADITIONAL TEST METHOD)
Test Equipment Needed:
• Amana power test kit R0157397 (Fahrenheit) or
• Menumaster power test kit M95D5 (Centigrade)
1. Fill the plastic container to the bottom of the 1000 ml.
lines with cool tap water.
2. Using the thermometer; Fahrenheit or Centigrade,
stir the water, measure and record the water
temperature. IMPORTANT: Initial water
temperature should be approximately 60°F (20°C).
3. Place the container on the center of the oven shelf
and heat the water for 63 seconds for ovens rated
less then 1550 watts or 33 seconds for ovens with
more then 1550 watts of power.
NOTE: Use a watch second hand, not the oven timer.
4. Stir the water, measure and record the temperature
of the water after heating time is completed.
5. Subtract the starting water temperature (Step 2) from
the ending water temperature (Step 4) to obtain the
temperature rise.
6. Refer to the Temperature Chart.
NOTE: Variation or errors in the test procedure will
cause a variance in the temperature rise
indication. Additional power tests should be
made if temperature rise appears marginal.
NOTE: Low line voltage may cause lower power output
(temperature rise).
NOTE: Always perform 3 tests for accuracy. Change
the water after each test.

Measurement With the Outer Case
Removed
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.
Measurement With a Fully Assembled Oven
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.
Record Keeping and Notification After
Measurement
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.
Microwave Energy Leakage Test
WARNING
!
Check for radiation leakage after servicing. Should the
leakage be more than 4mW/cm2inform 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.
Equipment
• Electromagnetic radiation monitor
• 600 cc glass beaker
Procedure For Measuring Radiation
Leakage
Note before measuring -
• 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 . 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.
2. Set the radiation monitor to 2450 MHz and use it
following the manufacturer’s recommended test
procedure to assure correct results.
3. While measuring the leakage, always use the two
inch (5 cm) spacer supplied with the probe.
4. 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.
