SENSOR COOKING (PLMV168, GLMV168)
The Sensor Cooking function uses a special gas
sensor which detects both humidty (steam) and
hydrocarbons (food odors) during the cooking
process, The sensor is a plug-in device located in
the vent area at the top left hand corner of the
cavity behind the grille.
SENSOR COOKING TEST (PLMV168, GLMV168)
1. Place 1/3 cup tap water in oven.
2. Touch VEGETABLE
, the oven starts immediately.
3. Control Beeps and shuts off.
4. Touch CLEAR/OFF
A) Test OK - Normal
B) Test Fails - Check Sensor
C) Test Fails - See Sensor Test Below

SMART BOARD
The SMART BOARD contains the power relay,
LVT, vent blower triac, surface light relays, and
other components to perform the proper
switching circuits. Several disconnect plugs are
also located on the SMART BOARD:
CON 01 - Ribbon Connector
CON 02 - Vent Blower Connector
CON 03 - Primary L.V.T & Main Relay
CON 04 - Door Sensing & Probe Connector
CON 05 - Gas Sensor Connector
(PLMV168, GLMV168)
Many diagnostic circuit tests can be made at the
disconnect plugs. (Refer to diagnosis flow chart
and simplified schematic in mini-manuals.)
CONTROL PERFORMANCE TEST
Set Clock-Touch clock pad, enter time of day,
AM/PM touch start pad.
Alternately touch each function pad and enter
time or temperature selection for the function.
Also change power levels.
Touch Clear-Off after each function test to
clear that function.
Repeat procedure for each function to
exercise each pad.
Control and display should respond to each entry.
Display should revert to Time-Of-Day after each
Clear-Off. Refer results to Diagnostic Flow Chart.
KEY PANEL TEST
If necessary the key panel pads can be verified
by a continuity test. For ease of handling the key
panel should be removed and placed on a flat
surface.
Check continity between connections at end of
ribbon (Use high scale).

IMPORTANT · RECONNECT
ALL GROUNDING DEVICES
ALL PARTS OF THIS APPLIANCE CAPABLE OF
CONDUCTING ELECTRICAL CURRENT ARE
GROUNDED. IF GROUNDING WIRES, SCREWS,
STRAPS, CLIPS, NUTS OR WASHERS USED TO
COMPLETE A PATH TO GROUND ARE REMOVED
FOR SERVICE, THEY MUST BE RETURNED TO
THEIR ORIGINAL POSITION AND PROPERLY
FASTENED.
GROUNDING SPECIFICATIONS
Leakage Current 0.5 mA. (Max.)
Ground Path Resistance 0.14 ohms (MAX.)
INSTALLATION REQUIREMENTS
ELECTRICAL
MWO Power 950 Watts
Power Source 120 VAC, 60 Hz.
Line Current 13.5 Amps. (1580Watts)
Over Current Protection 20 Amps *
* Requires 120 Volt, 20 Amp. parallel,
grounded separate circuit.
Working Voltage 105-130 VAC.
MICROWAVE LEAKAGE TEST
1. Place 275 ml. water in 600 ml. beaker
(WB64X5010)
2. Place beaker in center of oven shelf.
3. Set meter to 2450 MHz scale.
4. Turn oven "on" for 5 minute test.
5. Hold probe perpendicular to surface being
tested and scan surfaces at rate of one
inch/sec.
Test the following areas:
Entire perimeter of door and control panel
Viewing surface of door window
Exhaust vents
6. Maximum leakage 4 MW/CM
2
7. Record data on service invoice and
microwave leakage report.
NOTE : Maximum allowable leakage is 5 MW/
CM
2
. 4 MW/CM
2
is used to allow for
measurement and meter accuracy.
Inform the manufacturer of any oven found to
have emission in excess of 5 MW/CM
2
. Make
repairs to bring the unit into compliance at no
cost to owner and try to determine cause.
Instruct owner not to use oven if it has not
been brought into compliance.
HIGH VOLTAGE CAPACITOR
The high voltage capacitor has an internal shunt
resistor to automatically discharge the capacitor
when the oven turns "off". Under normal
operation the capacitor should fully discharge
within 30 seconds.
PERFORMANCE TEST
1. Measure line voltage (loaded). This test is based
on normal voltage variations of 105V to 130V.
Low voltage will lower output power and
temperature rise.
2. Place WB64 X0073 beaker containing one liter
water (1000ml, 59 F~75 F) on turn table and
record the starting water temperature with
an accurate thermometor.
(DO NOT USE ANY OTHER LOAD OR DISH AS
RESULTS WILL VERY FROM STANDARD!)
3. Set at HIGH power for 2 minutes, and 3 sec.
4. Turn on the oven.
5. Record end water temperature.
The minimum difference between the initial
and ending temperature should be:
INTERLOCKS (DOOR Latch Switches)
Interlocks are designed as follows:

Primary - Bottom switch operated by bottom
 latch pawl connected to line (L) leg.
HOW TO TEST INTERLOCKS
1. Disconnect power, open control panel,
and discharge capacitor.
Primary
2. Check Continuity of Com and N.O. :
Door Closed –
Door Open –
MONITOR SWITCH
The monitor switch is located between the top
and bottom interlocks. The monitor switch is
operated indirectly by the bottom latch pawl.
HOW TEST MONITOR
1. Disconnect power, open control panel, and
discharge capacitor.
2. Disconnect monitor switch leads, and test at
terminals:
Door Closed –
Door Open –
3. Reconnect switch wiring.
4. Test Circuit Operation:
A) Connect temporary jumper across relay
contacts and primary switch to simulate
shorted switch contacts. Locate
convenient connections in circuit to be
certain COM and N.O. terminals are used.
B) Connect OHM meter (Low Scale) across
the two line terminals of appliance power
cord.
Continuity must show:
Door Close –
Door Open –
C) Remove 20 Amp. Fuse
D) WARNING! After test remove temporary
jumper leads from interlocks and relay.
Reconnect monitor switch leads, replace
fuse.
E) Replacement of any parts in monitor
circuit requires repeating this entire
test procedure.
IMPORTANT : Check for microwave leakage
after replacing or adjusting
Door, Interlock switches or
brackets.
–Circuit must open
Ohms). If not check wiring of monitor
and interlock circuits.

INTERLOCK REPLACEMENT
The switch housing is not adjustable. It is fixed
on the front cavity with 2 screws.
IMPORTANT - CHECK FOR MICROWAVE
LEAKAGE AFTER REPLACING OR
ADJUSTING DOOR, INTERLOCK
SWITCHES OR BRACKETS.
CAUTION !
When safety interlocks and monitor switches are
repaired or replaced, check microwave leakage.
Perform microwave leakage check, if leakage
does not exceed 4 MW/CM it is performing
properly.
