• Do not leave fat heating unless you remain nearby. Fat

can ignite if overheated by spilling onto hot surfaces.

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. T ell the user not to operate the oven. B. Contact Maytag Appliances, 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, cap acitor, diode, and magnetron there is HIGH VOL T AGE. 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 Maytag.

9. IMPORT ANT : 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.

1 1.The Maytag 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 Dep artment immediately for further direction. Amana Appliances, Inc. will cont act the proper Government Agency upon verification of the test results.

Microwave Leakage Testing

WARNING

Check for radiation leakage after servicing. Should the leakage be more than 4mW/cm2 inform Amana Appliances, Inc. immediately . After rep airing 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.

• T o 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.

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 t aken 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 Af ter 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 .

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.
