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
(C) Before turning on microwave power for any service
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

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.

!
!
!
!
!
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.

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.
