Important Safety Information

CAUTION

Read the following information to avoid possible

exposure to microwave radiation:

The basic design of the Amana or Menumaster microwave ovens make it an inherently safe device to both user and servicer. 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 earthed

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 Maytag immediately.

5. Always have the oven disconnected when the outer case is removed except when making the "live" tests called for in this 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 earth 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 earthing, 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. 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 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

/64–inch (0.5 mm) or less.

1 1.The Amana or Menumaster microwave oven should

never be operated with:

• Any components removed and/or bypassed.

• Any of the safety interlocks found to be

defective.

• Any of the seal surfaces 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 8110 B, Holaday HI1501, HI1510, or HI1710 leakage monitor as outlined in the instructions. The maximum leakage level allowed is 4mW/cm2.

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

Important Safety Information

WARNING

Precautions to be observed before and during servicing to avoid possible exposure to excessive microwave energy , or electrical shock disconnect power to oven.

(A) Do not operate or allow oven to be operated with

door open.

(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

(C ) Before turning on microwave power for any 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

T o avoid risk of electrical shock, personal injury or death, make sure these earthing instructions are followed.

Earthing Instructions

WARNING

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 earthing 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.
