PRECAUTIONS TO BE OBSERVED BEFORE AND
DURING SERVICING TO AVOID POSSIBLE
EXPOSURE TO EXCESSIVE MICROWAVE
ENERGY

(a ) Do not operate or allow the 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: (1) interlock operation (2) proper door closing, (3)
seal and sealing surfaces (arcing, wear, and other damage), (4) damage to or loosening of hinges and
latches, (5) 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 the oven is released to the owner.

(e ) A microwave leakage check to verify compliance with the Federal Performance Standard should be

performed on each oven prior to release to the owner.

BEFORE SERVICING

Before servicing an operative unit, perform a microwave emission check as per the Microwave
Measurement Procedure outlined in this service manual.
If microwave emissions level is in excess of the specified limit, contact SHARP ELECTRONICS
CORPORATION immediately @1-800-237-4277.

Before Servicing

1. Disconnect the power supply cord , and then
remove outer case.

2. Open the door and block it open.

3. Discharge high voltage capacitor.

WARNING:RISK OF ELECTRIC SHOCK.

DISCHARGE THE HIGH-VOLTAGE
CAPACITOR BEFORE SERVICING.

The high-voltage capacitor remains charged about 60
seconds after the oven has been switched off. Wait for 60
seconds and then short-circuit the connection of the high­voltage capacitor (that is the connecting lead of the high­voltage rectifier) against the chassis with the use of an
insulated screwdriver.

Whenever troubleshooting is performed the power supply
must be disconnected. It may, in some cases, be necessary
to connect the power supply after the outer case has been
removed, in this event,

1. Disconnect the power supply cord, and then remove
outer case.

2. Open the door and block it open.

3. Discharge high voltage capacitor.

4. Disconnect the leads to the primary of the power
transformer.

5. Ensure that the leads remain isolated from other
components and oven chassis by using insulation tape.

6. After that procedure, reconnect the power supply cord.

When the testing is completed,

1. Disconnect the power supply cord, and then remove
outer case.

2. Open the door and block it open.

3. Discharge high voltage capacitor.

4. Reconnect the leads to the primary of the power
transformer.

5. Reinstall the outer case (cabinet).

6. Reconnect the power supply cord after the outer case is
installed.

7. Run the oven and check all functions.

After repairing

1. Reconnect all leads removed from components during
testing.

2. Reinstall the outer case (cabinet).

3. Reconnect the power supply cord after the outer case is
installed.

4. Run the oven and check all functions.

Microwave ovens should not be run empty. To test for the
presence of microwave energy within a cavity, place a cup
of cold water on the oven turntable, close the door and set
the power to HIGH and set the microwave timer for two (2)
minutes. When the two minutes has elapsed (timer at zero)
carefully check that the water is now hot. If the water
remains cold carry out Before Servicing procedure and re­examine the connections to the component being tested.

When all service work is completed and the oven is fully
assembled, the microwave power output should be checked
and a microwave leakage test should be carried out.

MICROWAVE MEASUREMENT PROCEDURE

A. Requirements:

1) Microwave leakage limit (Power density limit): The power density of microwave radiation emitted by a microwave oven
should not exceed 1mW/cm2 at any point 5cm or more from the external surface of the oven, measured prior to acquisition
by a purchaser, and thereafter (through the useful life of the oven), 5 mW/cm2 at any point 5cm or more from the external
surface of the oven.

2) Safety interlock switches: Primary interlock relay and door sensing switch shall prevent microwave radiation emission in
excess of the requirement as above mentioned, secondary interlock switch shall prevent microwave radiation emission in
excess of 5 mW/cm2 at any point 5cm or more from the external surface of the oven.

B. Preparation for testing:
Before beginning the actual measurement of leakage, proceed as follows:

1) Make sure that the actual instrument is operating normally as specified in its instruction booklet.

Important:
Survey instruments that comply with the requirement for instrumentation as prescribed by the performance standard for
microwave ovens, 21 CFR 1030.10(c)(3)(i), must be used for testing.

2) Place the oven tray in the oven cavity.

3) Place the load of 275±15 ml (9.8 oz) of tap water initially at 20±5C (68F) in the center of the oven cavity.
The water container shall be a low form of 600 ml (20 oz) beaker with an inside diameter of approx. 8.5 cm (3-1/2 in.) and
made of an electrically nonconductive material such as glass or plastic.
The placing of this standard load in the oven is important not only to protect the oven, but also to insure that any leakage
is measured accurately.

4) Set the cooking control on Full Power Cooking Mode.

5) Close the door and select a cook cycle of several minutes. If the water begins to boil before the survey is completed, replace
it with 275 ml of cool water.

C. Leakage test:

Closed-door leakage test (microwave measurement)

1) Grasp the probe of the survey instrument and hold it perpendicular to the gap between the door and the body of the oven.

2) Move the probe slowly, not faster than 1 in./sec. (2.5 cm/sec.) along the gap, watching for the maximum indication on the
meter.

3) Check for leakage at the door screen, sheet metal seams and other accessible positions where the continuity of the metal
has been breached (eg., around the switches, indicator, and vents).
While testing for leakage around the door pull the door away from the front of the oven as far as is permitted by the closed
latch assembly.

4) Measure carefully at the point of highest leakage and make sure that the highest leakage is no greater than 4mW/cm2, and
that the secondary interlock switch does turn the oven OFF before any door movement.

NOTE: After servicing, record data on service invoice and microwave leakage report.

OPERATION

DESCRIPTION OF OPERATING SEQUENCE

The following is a description of component functions
during oven operation.

OFF CONDITION

Closing the door activates the door sensing switch and
secondary interlock switch. (In this condition, the monitor
switch contacts are opened.)
When oven is plugged in, 120 volts A.C. is supplied to the
control unit. (Figure O-1).

1. The display will show SHARP, SIMPLY, THE, BEST,
PRESS, CLEAR, and PRESS, CLOCK.
To set any program or set the clock, you must first touch
the STOP/CLEAR pad. The display will clear, and " : "
will appear.

COOKING CONDITION

Program desired cooking time touching the NUMBER
pads. When the START pad is touched, the following
operations occur:

1. The contacts of relays are closed and components
connected to the relays are turned on as follows.
(For details, refer to Figure O-2)

RELAY CONNECTED COMPONENTS
RY 1 Oven lamp
RY 2 Power transformer/ Stirrer motor
RY4 Turntable motor
RY 5 Fan motor

2. 120 volts A.C. is supplied to the primary winding of the
power transformer and is converted to about 3.3 volts A.C.
output on the filament winding, and approximately 2000
volts A.C. on the high voltage winding.

3. The filament winding voltage heats the magnetron filament
and the H.V. winding voltage is sent to a voltage doubler
circuit.

4. The microwave energy produced by the magnetron is
channelled through the waveguide into the cavity feed­box, and then into the cavity where the food is placed to
be cooked.

5. Upon completion of the cooking time, the power
transformer, oven lamp, etc. are turned off, and the
generation of microwave energy is stopped. The oven will
revert to the OFF condition.

6. When the door is opened during a cook cycle, monitor
switch, door sensing switch, primary switch and secondary
switch and secondary interlock relay are activated with
the following results. The circuits to the stirrer motor, the
cooling fan motor, the turntable motor, and the high
voltage components are de-energized, and the digital
read-out displays the time still remaining in the cook cycle
when the door was opened.

7. The monitor switch is electrically monitoring the operation

of the primary and secondary switch and secondary
interlock relay and is mechanically associated with the
door so that it will function in the following sequence.
(1) When the door opens from a closed position, the

secondary interlock relay, door sensing switch, primary
and secondary switch open their contacts, and then
the monitor switch contacts close.

(2 ) When the door is closed from the open position, the

monitor switch contacts first open, and then the

contacts of the primary and secondary switch close.
If the primary switch, secondary switch and secondary
interlock relay fail with their contacts closed when the door
is opened, the closing of the monitor switch contacts will
form a short circuit through the monitor fuse, secondary
switch switch, primary switch and secondary interlock
relay, causing the monitor fuse to blow.

POWER LEVEL P-0 TO P-90 COOKING

When Variable Cooking Power is programmed, the 120
volts A.C. is supplied to the power transformer
intermittently through the contacts of relay (RY2) which is
operated by the control unit within an interval second time
base. Microwave power operation is as follows:

VARI-MODE ON TIME OFF TIME
Power 10(P-HI) 32 sec. 0 sec.

(100% power)
Power 9(P-90) 30 sec. 2 sec.

(approx. 90% power)
Power 8(P-80) 26 sec. 6 sec.

(approx. 80% power)
Power 7(P-70) 24 sec. 8 sec.
(approx. 70% power)

Power 6(P-60) 22 sec. 10 sec.
(approx. 60% power)

Power 5(P-50) 18 sec. 14 sec.
(approx. 50% power)

Power 4(P-40) 16 sec. 16 sec.
(approx. 40% power)

Power 3(P-30) 12 sec. 20 sec.
(approx. 30% power)

Power 2(P-20) 8 sec. 24 sec.
(approx. 20% power)

Power 1(P-10) 6 sec. 26 sec.
(approx. 10% power)

Power 0(P-0) 0 sec. 32 sec.
(0% power)

Note: The ON/OFF time ratio does not correspond with the

percentage of microwave power, because approx. 2
seconds are needed for heating of the magnetron
filament.

PROCEDURE

LETTER

Note: When defective components, the Control Unit or Key Unit are replaced, the defective part or parts

R KEY UNIT TEST

If the display fails to clear when the STOP/CLEAR pad is depressed, first verify the flat ribbon is making
good contact, verify that the door sensing switch (stop switch) operates properly; that is the contacts are
closed when the door is closed and open when the door is open. If the door sensing (stop switch) is good,
disconnect the flat ribbon that connects the key unit to the control unit and make sure the door sensing
switch is closed (either close the door or short the stop switch connecter). Use the key unit matrix
indicated on the control panel schematic and place a jumper wire between the pins that correspond to
the STOP/CLEAR pad making momentary contact. If the control unit responds by clearing with a beep,
the key unit is faulty and must be replaced.
If the control unit does not respond, it is
faulty and must be replaced. If a specific
pad does not respond, the above method
may be used ( after clearing the control unit)
to determine if the control unit or key pad is
at fault.

COMPONENT TEST

must be properly packed for return in the shipping carton, with its cushion material, in which the
new replacement part was shipped to you.
