2. Using an ohm meter, set the scale to
RX1000, and confirm the following ap-
proximate resistance readings.
a. BLK - RED = 6.2K ohms
b. RED - WHT = 3.1K ohms
c. BLK - WHT = 3.1K ohms
MICROWAVE LEAKAGE TEST
Caution: this test should not be performed dur-
ing a speedcook operation. This test should only
be performed during microwave only operation.
To perform a microwave leakage test, follow the
below steps:
1. Place 275 ml. of water in a 600 ml. beaker
(WB64X5010 - 600 ml beaker).
2. Place the beaker on the white ceramic tray.
3. Set the leakage meter to the 2450 MHz
scale.
4. Program the microwave for 5 minutes
(power level 10).
5. Hold the probe perpendicular to the sur-
face being tested and scan surfaces at a
rate of one inch/sec. Scan the following
areas:
- Entire door and control panel area
- Viewing surface of door window
- Exhaust vents
MICROWAVE PERFORMANCE TEST
This test will verify that the microwave oven high
voltage and magnetron circuits are operating to
performance specifications.
1. Using only a WB64X0073 beaker, place
a standard test load of 1 liter (1000 ml) of
water in the beaker. Measure and record
the water temperature prior to making the
test. The water temperature should be be-
tween 59° F. and 75° F.
2. Place the beaker in the center of the oven
on the white ceramic microwave cooking
tray.
3. Close the oven door. At the front control
panel, select: Microwave - Time Cook -
2:03 Minutes - Power Level 10. Press
START to begin microwave cooking.
4. At the end of the cooking cycle, remove
the beaker of water and measure and
record the temperature.
5. The minimum difference between the ini-
tial and ending temperatures should be
32° F at 120 VAC.
If the water temperature rose, but did not reach
the 32° F. minimum, suspect a problem with the
line voltage (test under full load) or magnetron
tube/high voltage circuit.
If the water temperature did not rise at all, sus-
pect a problem in the high voltage circuit.
HUMIDITY SENSOR TEST
This test should only be conducted at room tem-
perature (room temperature should not exceed
95° F.). Be sure that the oven cavity is dry and
free of moisture. The humidity sensor can be
tested from the front control panel area using the
following diagnostic procedure:
1. Disconnect the humidity sensor connec-
tor from the smart board (CN4, 3 pin - red
connector plug located at the top of the
smart board).
