(E) Check microwave leakage to verify compliance

with the federal performance standard should be performed on each oven prior to release to the consumer.

WARNING

To avoid risk of electrical shock, injury , or death, make sure these grounding instructions are followed.

Grounding Instructions

WARNING

Do not remove grounding prong when installing grounded appliance in a home or business that does not have three wire grounding receptacle, under no condition is grounding prong to be cut off or removed. It is the personal responsibility of the consumer to contact a qualified electrician and have properly grounded three prong wall receptacle installed in accordance with appropriate electrical codes

Servicing of Grounded Products

The standard accepted color coding for grounding wires is GREEN or GREEN WITH YELLOW STRIPE. These ground leads are NOT to be used as current carrying conductors. It is extremely important that the technician replace any and all grounds prior to completion of the service call. Under no condition should ground wire be left off causing a potential hazard to technicians and consumer.

Wiring

Good service practice is to never route wiring over terminals and/or sharp edges. This applies to any wiring without regard to the circuit voltage. Wire insulation material and thickness is designed and regulated for electrical spacing purpose only , but cannot always be relied upon because of possible cuts and/or abrasions, which can occur during servicing.

Important Safety Information

CAUTION

Read the following information to avoid possible exposure to microwave radiation:

The basic design of the Amana microwave oven makes it an inherently safe device to both use and service. However, there are some precautions which should be followed when servicing the microwave oven to maintain this safety . These are as follows:

1. Always operate the unit from an adequately grounded outlet. Do not operate on a two-wire extension cord.

2. Before servicing the unit (if unit is operable) perform the microwave leakage test.

3. The oven should never be operated if the door does not fit properly against the seal; the hinges or hinge bearings are damaged or broken; the choke is damaged, (pieces missing, etc.); or any other visible damage can be noted. Check the choke area to ensure that this area is clean and free of all foreign matter.

4. If the oven operates with the door open and produces microwave energy , take the following steps.

A. Tell the user not to operate the oven. B. Contact Amana Refrigeration, Inc.

immediately .

5. Always have the oven disconnected when the outer case is removed except when making the "live" tests called for in the Service Manual. Do not reach into the equipment area while the unit is energized. Make all connections for the test and check them for tightness before plugging the cord into the outlet.

6. Always ground the capacitors on the magnetron filter box and H. V. Capacitor with an insulated-handle screwdriver before working in the high voltage area of the equipment compartment. Some types of failures will leave a charge in these capacitors and the discharge could cause a reflex action which could make you injure yourself.

7. In the area of the transformer, capacitor, diode, and magnetron there is HIGH VOLTAGE. When the unit is operating - keep this area clean and free of anything which could possibly cause an arc or ground, etc.

8. Do not for any reason defeat the interlock switches– there is no valid reason for this action at any time; nor will it be condoned by Amana.

9. IMPORTANT: Before returning a microwave to a customer, check for proper switch interlock action. The primary and secondary switches MUST open when the door is actuated. The monitor switch MUST close at a 1/4 inch when the door is opened.

10.Before returning a microwave to a customer, verify the door spacing is reasonably uniform along the top, bottom, and sides and that it measures 1/8 inch or less.

11.The Amana microwave oven should never be operated with:

• Any components removed and/or bypassed.

• Any of the safety interlocks are found to be

failed.

• Any of the seal surfaces are defective, missing,

or damaged.

12.To ensure that the unit does not emit excessive microwave leakage and to meet the Department of Health Human Service guidelines, check the oven for microwave leakage using Narda Model 8100, 8200, Holaday HI1500, HI1501 or Simpson 380M leakage monitor as outlined in the instructions. The maximum leakage level allowed is 4mW/cm2.

13.If servicer encounters an emission reading over 4mw/cm2 the servicer is to cease repair and contact the Amana Service Department immediately for further direction. Amana Refrigeration, Inc. will contact the proper Government Agency upon verification of the test results.

Radiation Leakage Testing

WARNING

Check for radiation leakage after servicing. Should the leakage be more than 4mW/cm2 inform Amana Refrigeration, Inc. immediately . After repairing or replacing any radiation safety device, keep a written record for future reference, as required by DHHS and HEW regulations. This requirement must be strictly observed. In addition, the leakage reading must be recorded on the service repair ticket while in the customer’s home.

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 assembled 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 beaker which is graduated to 600 cc and place the beaker in the center of oven.

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 2–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.

Measurement With the Outer Panel Removed

DANGER

Avoid contacting any high voltage components.

Whenever you replace the magnetron, measure for radiation leakage before the outer panel 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 .

Auto Defrost

This microwave oven is preset with three defrost sequences. Using auto defrost is the best way to defrost frozen foods.

1. Press AUTO DEFROST pad.

2. Choose one of the following food categories.

Category Pad

number

Meat 1 Poultry 2 Fish 3

3. Enter the weight amount of food being defrosted.

4. Press START pad.

5. After 1/3 of the defrost time has lapsed. Display will prompt the operator to turn the food over. Open the door, turn the food over, and shield any warm portions of the food.

6. Close the door and press ST ART pad again.

7. After 2/3 of the defrost time has lapsed. Display will prompt the operator to turn the food over. Open the door, turn the food over, and shield any warm portions of the food. When the cook time has ended, three beeps will sound and “END” will appear in the display .

NOTE: If the oven door is not opened within 3 seconds,

unit will resume defrost cycle and display will continue to countdown.

Defrosting Tips

1. When using AUTO DEFROST cycle, the weight being entered is the net weight in pounds and tenths of pounds (the weight of the food minus the container).

2. Use AUTO DEFROST cycle only for raw food. Auto defrost obtains the best results when food is a minimum of 0°F, (taken directly from a freezer). If food has been stored in a refrigerator-freezer that does not maintain a temperature of 5°F or below , always program a lower food weight for a shorter defrosting time, to prevent cooking the food.

3. If the food is stored outside the freezer for up to 20 minutes, enter a lower food weight.

4. The shape of the package alters the defrosting time. Shallow rectangular packets defrost more quickly than a deep block.

5. Separate pieces as they begin to defrost. Separated pieces defrost more easily.

6. You can use small pieces of aluminum foil to shield foods like chicken wings, leg tips, and fish tails, but the foil must not touch the side of the oven. Foil causes arcing, which can damage the oven lining.

7. Shield areas of food with small pieces of foil if they start to become warm.

8. For better results, a preset standard time is included in the defrosting time.

Weight Conversion Chart

Consumers are used to food weights being in pounds and ounces which are fractions of a pound (for example 4 ounces equals 1/4 pound). However , in order to enter food weight in AUTO DEFROST cycle, specify pounds and tenths of a pound must be used. If the weight on food package is in fractions of a pound, use the following chart to convert the weight to decimals.

Sensor Operating Instructions

Sensor cook allows cooking of favorite foods without selecting cooking times and power levels. The display will indicate SENSING during the initial sensing period. The oven automatically determines required cooking time for each food item. When the internal sensor detects a certain amount of humidity coming from the food, it will tell the oven how much longer to heat. The display will show the remaining heating time. For best results for cooking by sensor, follow these recommendations.

1. Food cooked with the sensor system should be at normal storage temperature.

2. Glass Tray/(TURNTABLE) and outside of container should be dry to assure best cooking results.

3. Foods should always be covered loosely with microwavable plastic wrap, waxed paper , or a lid.

4. Do not open the door or touch the STOP/CLEAR key during the sensing time. When sensing time is over, the oven beeps twice and the remaining cooking time will appear in the display window. At this time you can open the door to stir, turn, or rearrange the food.

Sensor Cooking Guide

Appropriate containers and coverings help assure good sensor cooking results.

1. Always use microwavable containers and cover them with lids or vented plastic wrap.

2. Never use tight-sealing plastic covers. They can prevent steam from escaping and cause food to overcook.

3. Match the amount of the size of the container. Fill containers at least half full for best results.

4. Be sure the outside of the cooking container and the inside of the microwave oven are dry before placing food in the oven. Beads of moisture turning into steam can mislead the sensor.

Adding or Subtracting Cooking Time

If the SENSOR function is too long or too short, you can increase or decrease the cook time by 10% after choosing the function. Y ou can only increase or decrease cook time before cooking starts.

Popcorn

Popcorn pad allows consumer to pop commercially packaged microwave popcorn.

NOTES:

Weight Conversion Chart

Consumers are used to food weights being in pounds and ounces which are fractions of a pound (for example 4 ounces equals 1/4 pound). However, in order to enter food weight in AUTO DEFROST cycle, specify pounds and tenths of a pound must be used. If the weight on food package is in fractions of a pound, use the following chart to convert the weight to decimals.

Defrosting Tips

1. When using AUTO DEFROST cycle, the weight being entered is the net weight in pounds and tenths of pounds (the weight of the food minus the container).

3. If the food is stored outside the freezer for up to 20 minutes, enter a lower food weight.

4. The shape of the package alters the defrosting time. Shallow rectangular packets defrost more quickly than a deep block.

5. Separate pieces as they begin to defrost. Separated pieces defrost more easily .

7. Shield areas of food with small pieces of foil if they start to become warm.

8. For better results, a preset standard time is included in the defrosting time.
