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

. Make repairs to bring

the unit into compliance at no cost to owner and try to
determine cause. Instruct owner not to use oven until it
has been brought into compliance.

The standard test load is one liter (1000ml.) water with
a starting temperature of 59°F~75°F in a 1000ml. Use
the beaker of WB64 x 0073. (DO NOT USE ANY
OTHER LOAD OR DISH AS RESULTS WILL VARY
FROM STANDARD.)

1. Measure line voltage(loaded). This test is based on

normal voltage variations of 105V to 130V. Low volt-
age will affect power and temperature rise.

2. Place WB64 x 0073 beaker containing exactly one

liter (1000ml. 59°F~75°F) water on glass shelf and
record the starting water temperature with an accu-
rate glass thermometer (Robinar no. 12084).

3. Set at HIGH (Power).
4. Turn oven "ON" and timer for exactly two minutes

and three seconds.

5. At end of time period, record the water temperature.

The difference between the starting and ending tem-
peratures is the temperature rise.

Depending on line voltage the minimum temperature
rise should be:

Line Volts 

Minimum Temperature Rise

120V 43°F

The high voltage capacitor has an internal discharge
resistor to automatically discharge the capacitor when
the oven turns "OFF". Under normal operation, the
capacitor should fully discharge within 30 seconds.

1. Disconnect power and discharge capacitor. 
2. Disconnect capacitor and magnetron leads. 
3. Remove screw from capacitor strap. 
4. Remove capacitor strap.

The Primary, Door Sensing & Monitor switches are
mounted to a plastic latch board: on the right side of the
cavity. The Secondary interlock Relay (RY-2) is mount-
ed on the smart board. From top to bottom the switches
are as follows;
• Door Sensing 
• Monitor 
• Primary Interlock

1 Unplug oven, remove outer case, and discharge

capacitor. 

2. Check continuity of Switch:

• Door Closed: 0 

Ω

• Door Open: 

∞ Ω

The Bottom Latch pawl pushes horizontally and actuates
the lever of the monitor interlock opening the switch .

1. Unplug oven, remove outer case and discharge

capacitor. 

2 Check 20 Amp. fuse for continuity and proper size. 

Do not use any other fuse or size except 20 Amp.  

3. Remove one monitor switch lead to isolate switch. Check

continuity of switch with door open and door closed.
• Door Closed: 

∞Ω

• Door Open: 0 

Ω

4. Reconnect switch wiring.

5. Test Circuit Operation. 

A) Connect temporary jumper across relay contacts,

primary interlock and door sense switches to simu-
late shorted switch contacts. Locate convenient
connections in circuit to be certain COM and N.O.
terminals are used. 

B) Connect ohm meter (Rx1) across the line terminals

of the appliance cord. Continuity must show:
• Door Closed: some 

Ω

• Door Open: 0 

Ω

C) Remove 20 Amp. fuse-circuit must open ( 

∞ Ω

). 

If not check wiring of monitor and interlocks. 

6. WARNING! After test remove temporary jumper leads

from interlocks and relay. 

7. Replacement of any parts or monitor circuit requires

repeating this entire test procedure.

Perform microwave leakage test when replacing
or adjusting interlock switches or latch board.

Make continuity check between switch terminals. 
Normal reading are as follows:

• Door Closed: 0 

Ω

• Door Open: 

∞ Ω

Unplug oven, remove outer case, and discharge 
capacitor.
1. Power Relay (RY-2)

• Disconnect two leads from smart board relay.
• Check continuity across the terminals. 

The contacts should read open.

The Power relay and turntable control relay are mounted
on the control smart board and when it becomes faulty,
must be replaced as an assembly.

The Latch-Board is adjustable for door fit and switch
operation.
1. Disconnect power, remove outer case, and discharge

capacitor.

2. Loosen switch housing mounting screw at enlarged

hole in vertical flange.

3. Adjust each switch housing for proper switch opera-

tion, and door fit. Retighten screws.

Perform microwave leakage test when replac-
ing or adjusting interlock switches or brackets.

A. MICROWAVE EMISSION CHECK SHOULD BE PER-

FORMED PRIOR TO SERVICING IF OVEN OPERA-
TIVE.

B. DO NOT OPERATE OR ALLOW THE OVEN TO BE

OPERATED WITH DOOR OPEN.

C. IF THE OVEN OPERATES WITH THE DOOR OPEN: 

1 ) INSTRUCT THE USER NOT TO OPERATE THE 

OVEN. 

2) CONTACT THE MANUFACTURER AND THE CEN-

TER FOR DEVICES AND RADIOLOGICAL HEALTH
IMMEDIATELY.

D. 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 

E. BEFORE TURNING ON MICROWAVE POWER FOR

ANY TEST OR INSPECTION WITHIN THE
MICROWAVE GENERATING COMPARTMENTS,
CHECK THE MAGNETRON, WAVE GUIDE OR TRANS-
MISSION LINE, AND CAVITY FOR PROPER ALIGN-
MENT, INTEGRITY, AND CONNECTIONS.

F. ANY DEFECTIVE OR MISADJUSTED COMPO-

NENTS IN THE INTERLOCK, MONlTOR, DOOR
SEAL AND MICROWAVE GENERATION AND
TRANSMISSION SYSTEMS SHALL BE REPAIRED,
REPLACED, OR ADJUSTED BY PROCEDURE
DESCRIBED IN THIS MANUAL BEFORE THE OVEN
IS RELEASED TO THE OWNER.

G. A MICROWAVE LEAKAGE CHECK TO VERIFY

COMPLIANCE WITH THE FEDERAL PERFOR-
MANCE STANDARD SHOULD BE PERFORMED ON
EACH OVEN PRIOR TO RELEASE TO THE
OWNER.

TO PREVENT ELECTRICAL SHOCK. USE EXTREME
CAUTION WHEN DIAGNOSING OVEN WITH OUTER
CASE REMOVED AND POWER "ON". THE HIGH
VOLTAGE SECTION OF THE POWER SUPPLY
INCLUDING FILAMENT LEADS IS 4000 VOLTS
POTENTIAL WITH RESPECT TO GROUND.

When 20 Amp. fuse is blown due

to operation of monitor switch-both primary inter-
locks and the monitor switch must be replaced.
Also replace Relay (RY-2) when continuity
check shows contacts shorted.

Always be certain the capacitor is discharged before
servicing. Mechanically discharge by placing an 
insulated handle screw driver between the diode 
connection of the capacitor and oven chassis ground. 

Use screw head close to capacitor to insure
ground metal contact.
