Microwave Leak Test

1. Place 275 ml water in 600 ml beaker.
(Part # WB64 x 5010)
2. Place beaker in the center of the oven glass.
3. Set meter to 2450 MHz scale.
4. Turn ON for 5-minute test.
5. Hold the probe perpendicular to the surface
being tested. Scan surfaces at the rate of one
inch per second. Test the following areas:
• Entire perimeter of the door and control
panel
• Viewing surface of the door window
• Exhaust vents
6. Maximum leakage is 4 MW/CM
Note:
• Maximum allowable leakage is 5 MW/CM
MW/CM is used to allow for measurement and
2
meter accuracy.
• Inform the manufacturer of any oven found to
have emission in excess of 5 MW/CM
the owner not to use the oven until it has been
brought into compliance.

Performance Test

The standard test load is 1 liter (1000 ml) of water
with an initial temperature of 59°F ~ 75°F in a 1000
ml beaker (WB64 X 73 or Robonar 14882).
Performance Test for Microwave:
1. Record initial water temperature.
2. Run at high power for 2:03 minutes.
Note: Because the time can only be set in 15-
second increments on this model, set the time for
2:15 and end the test when the display reaches
0:12.
3. Record end water temperature.
The minimum difference between the initial and
ending temperatures should be: 30°F @ 120V.

Set Clock: Touch the clock pad, enter time of
day, AM/PM, and touch start pad.
Alternately touch each function pad and enter
time or temperature and 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.
The control and display should respond to each
entry.
The display should revert to Time-Of-Day after
each Clear-Off. Refer results to the diagnosis
fl ow chart.
Use a piece of paper 0.02 in. thick, 1 in. wide,
and 4 in. long (a dollar bill folded in half twice
lengthwise is about this size).
Open the oven door and place the paper
between the door and the front frame of the
oven cavity.
Close the oven door to capture the paper
between the door and the cavity front frame.
Draw the paper from between the door and the
cavity (check at the bottom and sides of the
door too). If there is resistance to the removal of
the paper, then the distance is correct.
