9 DESCRIPTION OF OPERATING SEQUENCE

NE-3280 / NE-2180 / NE-2180C

Variable power cooking control

The coil of power relays are energized intermittently by the
digital programmer circuit, when the oven is set at any power
selection except for High power position. The digital
programmer circuit controls the ON-OFF time of the power
relays contacts in order to vary the output power of the
microwave oven. The relation between indications on the
control panel and the output power of the microwave oven is as

shown in table.

NOTE:

ON-OFF time of power relays are changed by digital
programmer circuit when remaining cooking time or
selected cooking time are within 8 minutes at MED,
LOW and Defrost cooking mode.

9.1. Defrost control

When defrost power and defrosting time is selected and Start
pad is touched:

1. The digital programmer circuit (DPC) divides the total
defrosting time into 8 equal periods, consisting of four
defrosting periods, each followed by a standing period.
(See figure)

2. During defrosting power periods, power relay ON-OFF time
is controlled at Low power mode by DPC.

3. During Standing periods, power relay is always open

resulting in no microwave power.

NOTE:

Defrost time selected is converted into seconds by the
DPC but display will show selected time in minutes and
seconds as programmed. The total number of seconds
is divided into 8 time periods. The remainder (seconds
not equally divisible by 8) are added to the last standing
time period.

NE-3280 / NE-2180 / NE-2180C

10 CAUTIONS TO BE OBSERVED WHEN

TROUBLESHOOTING

Unlike many other appliances, the microwave oven is high­voltage, 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.

10.1. Check the grounding

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 ground ed properly before
beginning repair work.

10.2. Warning about the electric
charge in the high voltage
capacitor (
Figure).

For about 30 seconds after the oven is turned off, an electric
charge remains 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 and insulated handle
screwdriver or insulated jumper lead wire to discharge.

WARNING

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 oven energized.
DO NOT measure the voltage in the high voltage circuit including
filament voltage of magnetron.

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

10.4. When the 15 Amp. (NE­2180/NE-2180C) or 20 Amp.
(NE-3280) fuse is blown due to
the operation of interlock
monitor, replace the necessary
components according to the
following table.

WARNING

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

10.5. Avoid inserting nails, wire, etc.
through any 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 objects may work as an antenna and cause microwave
leakage.

16

NE-3280 / NE-2180 / NE-2180C

10.6. 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 energy leakage. (Refer to procedure
for measuring microwave energy leakage.)

2. Normal (cold) resistance readings should be as follows:

· Secondary winding Approx. 40Ω — 100Ω

· Filament winding Approx. 0Ω

· Primary winding Approx. 0Ω —3Ω

12.4. High voltage capacitor

1. Check continuity of capacitor with meter on highest OHM
scale.

2. A normal capacitor will show continuity for a short time, and
then indicate 9MΩ once the capacitor is charged.

3. A shorted capacitor will show continuous continuity.

4. An open capacitor will show constant 9MΩ.

5. Resistance between each terminal and chassis should be
infinite.

12.5. Magnetron

Continuity checks can only indicate an open filament or a
shorted magnetron. To diagnose for an openfilament or
shorted magnetron.

1. Isolate magnetron from the circuit by disconnecting the
leads.

2. A continuity check across magnetron filament terminals
should indicate one ohm or less.

14 PROCEDURE FOR MEASURING RADIATION LEAKAGE

WARNING

Check for radiation leakage after every servicing.
Should the leakage be more than 2 mW/square centimeter
(1mW/square centimeter for Canada) infrorm PASC, PSC, or PCI
immediately. Aftr repairing or replacing any radiation safety device,
keep a written record for future reference, as required by D.H.H.S. and
Health and Welfare Canada regulation. 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.

NOTE:

The U.S.government standard is 5mw/square
centimeter while in the customer’s home. 2mw/square
centimeter stated here is Panasonic’s own voluntary
standard.

NE-3280 / NE-2180 / NE-2180C

· Glass thermometer 212°F or 100°C

· 600cc glass beaker

14.2. Procedure for measuring
radiation leakage

Note before measuring

1. Do not exceed meter full scale deflection Leakage monitor

should initially be set to the highest scale.

2. To prevent false readings the test probe should be held by

the grip portion of the handle only and moved along the
shaded area shown in Figure right no faster than 1 inch/sec
(2.5cm/sec)

3. Leakage with the outer panel removed less than

5mw/square centimeter

4. Leakage for a fully assembled oven with door normally

closed less than 2mw/square centimeter

5. Leakage for a fully assembled oven [Before the interlock

switch (primary) is interrupted] while pulling the door less
than 2mw/square centimeter

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

in a beaker which is graduated to 600cc, and place the
beaker in the center of the oven.

2. Set the radiation monitor to 2450MHz and use it following

the manufactuer’s recommended test procedure to assure
correct results.

3. When measuring the leakage, always use the 2 inch (5cm)

spacer supplied with the probe.

4. Press the start button and with the magnetron oscillating,

measure the leakage by holding the probe perpendicular to
the surface being measured.

1. Measurement with the outer panel 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.

WARNING

Avoid contacting any high voltage parts.

14.4. At least once a year, have the
radiation monitor checked for
calibration by its
manufacturer.

2. Measurements 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.

14.3. 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.
A copy of this repair ticket and the microwave leakage
reading should be kept by repair facility.

2. Should the radiation leakage be more than 2mw/square
centimeter after determining that all parts are in good
condition, functioning properly, and genuine replacement
parts as listed in this manual have been used, immediately
notify PASC or PSC.

15 TROUBLESHOOTING GUIDE

CAUTION

1. Check grounding before checking for trouble.

2. Be careful of the high voltage circuit.

3. Discharge high voltage capacitor.

4. 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.

When disconnecting a plastic connector from a terminal, you must hold the plastic connector instead of the lead wire and then disconnect it,
otherwise lead wire may be open or the connector cannot be removed.

5. Be sure to ground any static electric charge built up in your body, before handling the D.P.C.

6. A 208-230V AC is present at the shaded area ( ) of the power supply circuit board (Terminals of power relays and primary circuit of low voltage
transformer). When troubleshooting, be cautious of possible electrical shock hazard.

First of all operate the microwave oven following the correct operating procedures described on pages 4 of this service manual in
order to find the exact cause of any trouble.
