5 Test Mode
5.1. Component test procedure
5.1.1. High voltage transformer
1. Remove connections from the transformer terminals and
check continuity.
2. Normal (cold) resistance readings should be as follows:
Secondary winding Approx. 80Ω-120Ω
Filament winding Approx. 0Ω
Primary winding Approx. 0Ω-3Ω
5.1.2. 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.
5.1.3. Magnetron
Continuity checks can only indicate an open filament or a
shorted magnetron. To diagnose for an open filament 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.
3. A continuity check between each filament terminal and
magnetron case should read open.

5.1.4. Diode
1. Isolate the diode from the circuit by disconnecting the
leads.
2. With the ohmmeter set on the highest resistance scale,
measure the resistance across the diode terminals.
Reverse the meter leads and again observe the resis-
tance reading. Meter with 6V, 9V or higher voltage batter-
ies should be used to check the front-to-back resistance
of the diode, otherwise an infinite resistance may be read
in both directions.
A normal diode's resistance will be infinite in one direction
and several hundred kΩ in the other direction.
5.1.5. Protector diode
1. Isolate the protector diode assembly from the circuit by
disconnecting its leads.
2. With the ohmmeter set on the highest resistance scale,
measure the resistance across the protector diode termi-
nals. Reverse the meter leads and again observe the
resistance reading. A normal protector diode’s resistance
will be infinite in both directions. It is faulty if it shows con-
tinuity in one or both directions.
5.1.6. Key board (Membrane switch)
Check continuity between switch terminals, by tapping an
appropriate pad on the key board. The contacts assignment of
the respective pads on the key board is as shown in digital pro-
grammer circuit.
5.1.7. Temp sensor (Thermal protector)
A temp sensor is mounted on exhaust guide. Its purpose is to
automatically shut off the oven in case the cavity overheats for
any reason.
The thermal protector will operate at 257°F (125°C).
The device is connected to the digital programmer circuit on
touch control models.
When the thermal protector exceeds its temperature it will turn
off the power to oven cavity and display will go to reset mode.
The cooking program can be reset after cool-down.
THERMISTOR RESISTANCE VALUE
30K-120K at 10°C-30°C (50°F-86°F)

6 Troubleshooting Guide
6.1. Cautions to be observed when
troubleshooting
Unlike many other appliances, the microwave oven is high-volt-
age, high-current equipment. Though it is free from danger in
ordinary use, extreme care should be taken during repair.
6.1.1. Check the grounding
Do not operate on a 2-wire extension cord. The microwave
oven is designed to be used in a completely grounded condi-
tion. It is imperative, therefore, to make sure it is properly
grounded before beginning repair work.
6.1.2. If the door lock, the door switch,
the door seal or the door develops
a malfunction, be sure not to oper-
ate the oven until complete repairs
are made.
If the oven is operated with any of these parts in imperfect con-
dition, hazardous microwave leakage might occur.
6.1.3. Warning about the electric charge
in the high voltage capacitor
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, wait
30 seconds and short the terminal of the high voltage capacitor
(terminal of lead wire from diode) to chassis ground with an
insulated jumper lead wire or an insulated handle screwdriver
discharge.
6.1.4. When parts must be replaced,
remove the power plug from
the outlet.
6.1.5. When the 2.5 Amp. and/or 12 Amp.
fuse is blown due to the operation
of the interlock monitor switch.
1. This is mandatory. Refer to “Measurements and
Adjustments” for these switches.
2. When replacing the fuse, confirm that it has the
appropriate rating for these models.
3. When replacing faulty switches, be sure mounting tabs
are not bent, broken or otherwise deficient in their ability
to hold the switches.
6.1.6. Avoid inserting nails, wire, etc.
through holes in unit during opera-
tion.
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.
