Humidity Sensor

The humidity sensor is mounted on the exhaust duct
on the left side of the oven. The outer cover must be
removed to access the humidity sensor. (See
Removal / Partial Removal
connected to the power board at location CN8. The
humidity sensor is held in place by 2 Phillips-head
screws.
The humidity sensor detects the increasing humidity
released during cooking. The oven automatically
adjusts the cooking time to various types and
amounts of food.
Humidity Sensor Test
Note:
• The oven should be plugged in at least 5
minutes before test.
• Room temperature should not exceed 95°F.
• Be sure the exterior of the cooking container
and interior of the oven are dry.
• No sensor cooking is available while the oven
is hot. Wait 5 minutes to allow oven to cool
enough to use sensor cooking.
To test the humidity sensor, it is necessary to access
the control panel. (See Control Panel Assembly.) The
humidity sensor wire harness must be disconnected
from CN8 on the power board. On the humidity
sensor wire harness, check for approximate
resistance values between:
• Black-Red = 6.5 K
• Red-White = 3.25 K
• Black-White = 3.25 K
