CAUTI ON

Read the following information to avoid possible

exposure to microwave radiation:

The basic design of the Amana and 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.

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 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 Maytag Service Department immediately for further direction. Maytag 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

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, 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.

Page 9

General Information

Placement of the Oven

Do not install microwave next to or above source of heat, such as a deep fat fryer. This could cause the microwave to operate improperly and could shorten the life of electrical components.

Install microwave on a level countertop surface.

Do not block or obstruct oven filter. Allow access for cleaning.

All air vents must be kept clear during cooking. If air vents are covered during operation the oven may overheat. In this case, a sensitive thermal safety device automatically turns the oven off. The oven will be inoperable until the oven has cooled sufficiently.

Radio Interference

Microwave oven operation may cause interference to radio, television, or similar equipment. Reduce or eliminate interference by doing the following:

• Clean the door and sealing surfaces of microwave oven according to instructions in “Care and Cleaning” section.

• Place radio, television, etc. as far as possible from the microwave oven.

• Use a properly installed antenna on radio, television, etc. to obtain stronger signal reception.

Earthing Instructions

This appliance MUST be earthed. If an electrical short circuit occurs, earthing reduces the risk of electric shock by providing an escape wire for the electric current. The cord for this appliance has a earthing wire with a earthing plug. Place the plug into an outlet that is properly installed and earthed. Do not use a two–prong adapter.

WARNING

To avoid risk of electric shock, personal injury or death, do not alter the plug and use earthing plug properly.

A—Allow at least 1½ inches / 3.81 centimeters of clearance

around top and sides of equipment. Proper air flow around equipment cools electrical components. With restricted air flow, oven may not operate properly and life of electrical parts is reduced.

Consult a qualified electrician if you do not understand the earthing instructions or if you wonder whether the appliance is properly earthed.

Keep the electrical power cord dry and do not pinch or crush it in anyway.

The wires in the power cord are colored in accordance with the following code:

• Green/Yellow: Earth

• Blue: Neutral

• Brown: Live

Troubleshooting Procedures

When you get a complaint from customers, evaluate the complaint carefully. If the following symptoms apply, instruct the customer in the proper use of the microwave oven. This can eliminate an unnecessary service call.

CAUTION

• Verify proper earthing before checking for trouble.

• Be careful of the high voltage circuit.

• Discharge the high voltage capacitor.

• When checking the continuity of the switches or the high voltage transformer, disconnect one lead wire from these parts and then check continuity with the AC plug removed. To do otherwise may result in a false reading or damage to your meter.

• Do not touch any part of the circuit on the controller, since static electric discharge may damage the control panel. Always touch yourself to earth while working on this panel to discharge any static charge built up in your body.

Service Information

To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor before servicing, unless testing requires power.

Proper Handling of Magnetron Tubes

CAUTION

A magnetron tube, like a radio or television tube must be handled with a reasonable amount of care. When handling a tube, always handle by the housing only. Use caution not to touch or strike the ceramic portion at the top. The carton used to ship service replacement tubes is reusable.

Magnetron Failure Modes

Magnetron failures that have been identified are generally grouped into categories shown below.

1. Shorted Air - This is a case where the tube has had the vacuum

envelope destroyed and air has entered the tube. This will cause internal arcing and high secondary current if high voltage is applied.

R.F. Capacitors - May short to chassis. This condition

will also cause loss of high voltage.

WARNING

2. Open Heater (Filament) - Can be determined by a ohmmeter when transformer leads are disconnected. Resistance is normally less than one ohm; filament does not short internally. Any tube removed should be checked since usage tends to make the filament more fragile. Later handling and shipping may open the filament and thereby mask the true failure mode when checked at the factory.

3. Low Power - Caused by “wearout” of the emission characteristics of the directly heated cathode. Symptoms are: (1) tube current will take longer to get to operating point than a new tube (normally about 2 - 3 seconds), (2) tube current does not get high enough to cause the tube to oscillate with normal line voltage, (3) oven produces low power into a load, two-thirds or less than normal.

4. Physical Damage - Caused by mishandling of magnetron tube.

Microwave Leakage Testing

To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor before servicing, unless testing requires power.

WARNING

Measurement with the Outer Panel

WARNING

Check for radiation leakage after servicing. Should the leakage be more than 4 mW/cm 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 in the customer’s home.

Equipment

• Electromagnetic radiation monitor

• 600 cc glass beaker or plastic power bowl

inform Maytag

Removed

WARNING

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

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 /cm less.

• Leakage for fully assembled oven with door normally closed ...4 mW/cm

• Leakage for a fully assembled oven (before the latch switch (primary) is interrupted) while pulling the door ... 4 mW/cm

1. Pour 275 cc ±15 cc (9 oz ±1/2 oz) of 20°C ± 5°C (68°F ± 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 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.

or less.

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.

Operating Instructions for the Holaday HI1501, HI1510, HI1710, and HI1801

Purpose of these monitors is to check radiation leakage around microwave oven door or other places where radiation could possibly occur.

Instrument measures radiation leakage in milliwatts per square centimeters (mW/cm

used with the 2" (5 cm) cone spacer. Water load of 275 cc. (approximately 1 the oven and used as a load during leakage tests.

Operate the instrument on its internal 9 Volt battery power supply. “Range” switch is used on low and high while using test probe. On an oven with an unknown leakage, use high scale then switch to low scale and test for low leakage. “Bat Test” switch is used to check the battery and probe on the Holaday Instruments. If either is faulty, meter needle will not read above “Test Minimum” or battery mark on meter. Holaday Instrument has a probe test switch position. Meter needle must indicate in the “OK probe test” portion of the scale when in this position. Zero control is used to zero the needle. “ON-OFF” switch provides a means of turning the operating voltage on or off. “Range Multiplier” switch provides a means of selection either 0-2 or 0-10 and 0-100 on the Holaday Instruments sensitivity ranges.

). Probe should be

/3 cup), is to be placed in

WARNING

Hold probe perpendicular to cabinet door. Place cone of probe on the door and/or cabinet door seam and move along the seam. If leakage of the oven is unknown, move probe slowly. Proceed with care in order not to exceed a full scale reading of meter. When testing near a corner or access area of door, keep probe perpendicular to the areas making sure probe end at the base of the cone does not get closer than 2” (5cm) to any metal. If it does, an erroneous reading may result.

Always use the 2” (5cm) spacer with probe. Also, always proceed carefully in areas of high leakage or probe can be accidentally burned-out. Rotating antenna causes high peaks of energy. Although meter has averaging capabilities, probe will react instantaneously to peak power changes which will cause burn-out.

Test probe must be held by the grip portion of the handle, otherwise a false reading may result if operators hand is between the handle and probe.

If oven is likely to have a large amount of leakage, approach oven slowly with the probe, while observing meter. This is achieved by holding the probe two or three feet from oven surface or gap between door and oven body while observing meter. When high leakage is expected, do not move probe horizontally along the oven surface. This could cause possible probe burn-out. Greatest leakage is generally found at the corners. After maximum leakage is established to be within the meter scale range, then probe may be moved horizontally around the door surface.

Power Test

All Amana and Menumaster microwave oven power outputs are rated using the IEC705 standards. Using the IEC705 test method requires precision measurements and equipment that is not practical to be performed in the field. Using the test shown below will indicate if the oven performance is satisfactory.

Test equipment required:

• 1000 ml test container and thermometer (Amana power test kit R0157397 Fahrenheit / Menumaster power test kit M95D5 Celsius).

• Digital watch / watch with a second hand for use on ovens with electromechanical timers.

Important Notes:

• Low line voltage will cause low temperature rise / power output.

• Ovens must be on a dedicated circuit, properly grounded, and polarized. Other equipment on the same

circuit may cause a low temperature rise / power output.

• This test and results are not a true IEC705 test procedure and are only intended to provide servicers with an easy means of determining if the microwave oven cooking output is correct.

Procedure

1. Fill the test container to the 1000 ml line with cool tap water.

NOTE: Water temperature should be approximately 60°F / 16°C

2. Using the thermometer, stir water for five to ten seconds; measure, and record the temperature (T1).

3. Place test container of water in the center of oven cavity and close door.

4. Heat the water for a 33-second full power cycle.

NOTE: Use a digital watch or a watch with a second hand for ovens with electromechanical timers.

1. At end of the cycle, remove test container. Using the thermometer, stir water for five to ten seconds and record temperature (T2).

2. Subtract the starting water temperature (T1), from the ending water temperature (T2) to obtain the temperature

back of oven and back wall.

C—Allow at least 2” (5.1 cm) of clearance around sides

of oven.
