Humidity Sensor
The humidity sensor is mounted to the exhaust duct
on the left side of the oven. The outer cover must
be removed to access the humidity sensor. (See the
Removing Upper Oven section in this guide.) The
humidity sensor is connected to the power board at
location CN5. The humidity sensor is held in place by
two 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.
