Troubleshooting
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 after using Broil, Toast,
Warm, Convection Bake, or Speedcook to allow
the oven to cool enough to use sensor cooking.
To test the Humidity Sensor, it is necessary to pivot
the Control Panel Assembly out from the oven. (See
Control Panel Removal.
) The Humidity Sensor wire
harness must be disconnected from CN8 on the
Smart Board. On the Humidity Sensor wire harness,
check for approximate resistance values between:
Black-Red = 6.5 K
