(B) Make the following safety checks on all ovens to

be serviced before activating the magnetron or other microwave source, and make repairs as necessary:

• Interlock operation

• Proper door closing

• Seal and sealing surfaces (arcing, wear, and other damage)

• Damage to or loosening of hinges and latches

• Evidence of dropping or abuse

service test or inspection within the microwave generating compartments, check the magnetron, waveguide or transmission line, and cavity for proper alignment, integrity, and connections.

(D) Any defective or misadjusted components in the

interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced or adjusted by procedures described in this manual before oven is released to the consumer.

(E) Check microwave leakage to verify compliance

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

WARNING

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

Earthing Instructions

WA RNIN G

To avoid the risk of electrical shock or death, this equipment must be earthed.

WA R N IN G

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

Should a two prong adapter plug be required temporarily it is the personal responsibility of the consumer to have it replaced with properly earthed three prong receptacle or the two prong adapter properly earthed by a qualified electrician in accordance with appropriate electrical codes.

Servicing of Earthed Products

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

Microwave Energy Leakage Test

Measurement With the Outer Case

WA RN ING

Removed

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.

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.

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.

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.
