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

/64–inch (0.5 mm) 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

/64–inch (0.5 mm) or less.

11. 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/cm

13.If servicer encounters an emission reading over

4 mw/cm

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.
