Important Product Information

WA R N ING

Precautions to be observed before and during servicing to avoid possible exposure to excessive microwave energy .

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

the 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, wave guide 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.

WARNING

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

Grounding Instructions

WA RN IN G

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

Servicing of Grounded Products

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

Important Safety Information

CAUTION

Do not become exposed to radiation from the microwave generator or other parts conducting microwave energy .

Basic design of this microwave oven makes it an inherently safe device to both use and service. However, there are some precautions which should be followed when servicing microwave oven to maintain this safety . These are as follows:

1. Always operate unit from an adequately grounded outlet. Do not operate on a two-wire extension cord.

2. Before servicing unit (if unit is operable) perform microwave leakage test.

3. Oven should never be operated if door does not fit properly against seal, hinge/hinge bearings are damaged or broken; choke is damaged, (pieces missing, etc.); or any other visible damage can be noted. Check choke area to ensure that this area is clean and free of all foreign matter . If any above problems occur take the following steps:

• Tell the user not to operate the oven.

• Contact Amana immediately .

4. If oven operates with door open and produces microwave energy , take the following steps:

• Tell the user not to operate the oven.

• Contact Amana immediately .

5. Always have oven disconnected when outer case is removed except when making "live" tests called for in the service manual. Do not reach into equipment area while unit is energized. Make all connections for the test and check them for tightness before plugging cord into outlet.

6. Always ground capacitors on magnetron filter box and H.V . capacitor with an insulated-handle screwdriver before working in high voltage area of equipment compartment. Some types of failures will leave a charge in 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 unit is operating, keep area clean and free of anything which could possibly cause an arc or ground, etc.

8. DO NOT for any reason defeat interlock switches, there is no valid reason for this action at any time; nor

will it be condoned by Amana.

9. Microwave oven should never be operated with:

• Any components removed and/or bypassed

• Any of the safety interlocks are found to be defective

• Any of the seal surfaces are defective, missing, or damaged

10.To ensure that unit does not emit excessive microwave leakage and to meet Department of Health and Human Services guidelines check oven for microwave leakage using Narda Model 8100, 8200, Holaday HI1500, HI1501, or Simpson 380M leakage monitor as outlined in instructions. Maximum leakage level allowed is 4mw/cm2 .

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

12.Install or locate this equipment ONLY in accordance with the installation instructions in this manual.

Important Product Grounding and Outlet Information

Typical grounding type wall receptacle

Typical power supply cord with 3-prong grounding plug

Typical type wall receptacle

Typical power supply cord with 3-prong grounding plug

Temporary grounding adapter (NOT used in Canada)

NOTE: 120 V olt, 15 A. Cord and Receptacle shown. Typical instructions also apply to 120 V, 20 AMP, and

208/240 V cords and receptacles. Proper grounding and polarization of 120 V wall outlets.

Explanations

Polarization—This means that the larger slot must be

neutral and the small slot must be hot (live). Mispolarized—The outlet is miswired so that the larger

slot is hot (live) and the smaller slot is neutral. Grounded—This means the round hole connection is

connected to earth ground through a connection to the main power panel.

Ungrounded—The round hole connection is not complete to earth ground and/or the main power panel.

FIGURE 1

For the safety of our customers and the service technician ALL appliances having a three (3) prong power cord MUST be connected to a properly polarized AND grounded wall outlet. This information was written for those who do not understand grounding and polarization of a wall outlet. A 120 Volt wall outlet must always be wired as shown in Figure 1.

Important Product Grounding and Outlet Information

Test Procedures (2 Methods)

Method 1

Purchase and use a ground monitor (Figure 2, Page 8) available under Amana Part Number R0193001 or it can be purchased locally . The lamps inside the monitor indicates a correctly or incorrectly wired outlet by instructions imprinted on the monitor body .

Method 2 Voltmeter - (Use scale over 125 Volts A.C.)

Test A - "H" to "N" must indicate line voltage. Test B - "H" to "G" must indicate line voltage. Test C - "N" to "G" must indicate zero (0) volts.

If "N" to "G" indicates line voltage the outlet is mispolarized. If "H" to "G" indicates zero (0) volts the outlet is not grounded.

FIGURE 2

WARNING

Wiring changes or grounding of wall outlet are to be made only by a qualified electrician.

In the event a grounding adaptor (not used in Canada) has been TEMPORARILY installed the test procedures described in Methods 1 and 2 above should be used (Figure 3).

FIGURE 3

NOTE: The green wire or tab should be connected to a

proper ground by a qualified electrician.

General Test Information

Most testing in the manual is conducted with an ohmmeter using a multiplier scale of X10k (k-thousand ohms). When using this scale, it is important that your fingers do not touch the metal parts of the test probes. To do so will give a false indicate of the ohm reading.

CAUTIONS and WARNINGS to be Observed During

Disassembly and Troubleshooting

Unlike many other appliances, the microwave oven is high-voltage, high-current equipment. Though it is free from danger in ordinary use, extreme care should be taken during repair .

CAUTION

Servicemen should remove their watches whenever working close to or replacing the magnetron.

Checking the ground

Do not operate on a 2-wire extension cord. The microwave oven is designed to be used when grounded, it is imperative, therefore, to make sure it is grounded properly before beginning repair work.

WARNING

After the oven is turned off, an electric charge may remain in the high voltage capacitor . When replacing or checking parts, remove the power plug from the outlet and short the terminal of the high voltage capacitor (terminal of lead wire from diode) to chassis ground with an insulated handle screwdriver and discharge.

DANGER

There is high voltage present, with high current capabilities in the circuits of the high voltage winding and filament winding of the high voltage transformer . It is extremely dangerous to work on or near these circuits with the oven energized. Do not measure the voltage in the high voltage circuit including filament voltage of the magnetron.

When parts must be replaced, remove the power cord from the outlet.

WARNING

When the fuse is blown due to the operation of the monitor switch, replacement of complete interlock switch must be performed.

1. This is mandatory. Refer to page 29 for the necessary adjustments for this switch assembly .

2. When replacing the fuse, confirm that it has the appropriate rating for these models.

CAUTION

Avoid inserting nails, wire, etc. through and holes in the unit during operation.

Never insert a wire, nail, or any other metal object through the lamp holes on the cavity or any other holes or gaps because such object may work as an antenna and cause microwave leakage.

Confirm After Repair

1. After repair or replacement of parts, make sure that the screws of the oven, etc. are neither loose nor missing.

2. Make sure that all electrical connections are tight before inserting the plug into the wall outlet.

3. Check for microwave leakage. (Refer to procedure for measuring microwave leakage.)

WARNING

Never touch any circuit with your hand nor with an insulated tool during operation.

RE220002 Rev. 6 10

General Information and Operating Instructions

Service Access

Component servicing is done by lowering the back panel, removing the control panel assembly , and component module panel. Refer to the disassembly section for specific components replacement and adjustment procedures.

WARNING

All component mounting panels must be grounded to the oven chassis before performing any troubleshooting.

Serial Plate Location

Some models

5. The FS14EVP , FS16EVP, FS17, FS17EVP, FS20, FS20EVP oven must be adjusted to the proper supply voltage. This oven is manufactured preset for 240 volts. If the supply voltage is less than 220 volts, remove the small cover on the back of the oven and move the voltage adjusting connector to the 208 volt tap connector. Incorrect tap setting can cause component damage.

6. Plug the FS10 EVP, FSP10, FSP11, FSP11SS and VEND10 oven into a standard 120 volt outlet. Plug the FS14 EVP, FS16EVP, FS17, FS17EVP, FS20, FS20EVP into a 208 or 240 volt outlet. Be sure the electrical outlet is rated for at least 20 amperes and the microwave oven is the only appliance on the circuit.

Important Electrical Grounding Instructions

This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.

Filter

Some models

Installation Instructions

1. Unpack the oven carefully and examine it for shipping damage. If damage is evident, notify the local carrier immediately and file a damage claim. Menumaster assumes no liability for damage incurred in transit.

2. If the oven has been stored in an extremely cold area, wait several hours before plugging the oven into an outlet.

3. Remove all material from the oven interior.

4. Place the oven in the chosen location. Make sure there is at least one inch of clearance on the top and side and the air intake (filter) is not close to a high temperature source. Example: A deep fat fryer.

WARNING

Improper use of the grounding plug can result in a risk of electric shock.

Consult a qualified electrician or serviceman if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded. If it is necessary to use an extension cord, use only a three-wire extension cord that has a three-blade grounding plug, and a three-slot receptacle that will accept the plug on the appliance. The marked rating of the extension cord shall be equal to or greater than the electrical rating of the appliance.

7. Verify correct operation by performing system diagnosis test.

On newer models an audible tone may sound but no number will appear in the display .

Preventive Maintenance

NOTE: Do not use scouring pads, powders or other

abrasive materials on any of the oven surfaces.

Regularly

1. Wipe up all spillage as it occurs.

2. Do not allow food particles or grease to collect on the plastic stirrer cover and light cover or on the inner door and oven cavity front surfaces. A build-up of food or grease in these areas can result in damage to the surfaces as well as in loss of cooking power.

Daily

1. Wipe the plastic stirrer cover and oven light cover with a cloth or sponge dampened in a mild detergent solution.

2. Wipe all surfaces in the oven cavity with the dampened cloth or sponge and then dry with a clean cloth.

3. Wipe the inner door surface and oven cavity front with a mild detergent solution, making sure to remove all food particles.

Weekly

1. Remove the air intake filter and wash it in hot water to remove grease and dust that collects and obstructs the air flow.

2. Check the door assembly for hinge and latch tightness.

Semi-Annually

1. Perform radio frequency (r.f.) leakage test. Test anytime r .f. leakage is suspected or maintenance is performed on door assembly , interlock system, or magnetron.

2. Verify correct operation by performing System Diagnosis.

Magnetron Service Information

Proper Handling of Magnetron Tubes

A magnetron tube must be handled with care. When handling a tube, always handle by the housing only . Use caution not to touch or strike the ceramic or metal portion at the top.

NOTE: The carton used to ship service replacement

tubes is reusable. All inoperative tubes must be returned to the factory in the carton.

Magnetron Failure Modes

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

1. Shorted a. 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 circuit if high voltage is applied.

b. R.F. Capacitors—May short to chassis. This

condition will also cause loss of high voltage.

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

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

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

RE220002 Rev. 6 28

Procedure for Measuring Microwave Energy Leakage

Measurement with the Outer Panel

WARNING

Check for radiation leakage before and during every servicing. Should the leakage be more than 4mW/cm (to allow for measurement uncertainty) inform Amana Appliances immediately . After repairing or replacing any radiation safety device, keep a written record for future reference, as required by the Department of Health and Human Services and CDRH regulation. This requirement must be strickly observed. In addition, the leakage reading must be recorded on the servie repair ticket while in the customer's location.

Removed

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.

DANGER

To avoid risk of severe personal injury or death , avoid contacting any high voltage components.

Equipment

• Electromagnetic radiation monitor

• Glass thermometer 212°F. or 100°C.

• 600 cc glass beaker

Procedure for Measuring Radiation Leakage

Note before measuring:

a. Do not exceed meter full scale deflection.

Leakage monitor should initially be set to the highest scale.

b. To prevent false readings the test probe should be

held by the grip portion of the handle only . The scan speed is equal to 1" per antenna revolution of 1" per second if antenna speed is unknown. Areas to be checked are all seal areas, window , and any venting parts.

c. Leakage with the outer panel removed . . . 4mW/

cm2 or less.

d. Leakage for a fully assembled oven with door

normally closed . . . 4mW/cm

e. Leakage for fully assembled oven (before the latch

switch (primary) is interrupted) while pulling the door . . . 4mW/cm2 or less.

or less.

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

• 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.

A copy of the repair ticket and the microwave leakage reading should be kept by repair facility.

1. Pour 275 ± 15 cc (9 oz. ± 1/2 oz) or 20 ± 5°C. (68°F. ± 9°F.) water in beaker which is graduated to 600 cc and place the beaker in the center of the oven.

2. Set the radiation monitor to 2450 MHz and use it following the manufacturer's recommended test procedures 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.
