Code Description/Results
Possible Cause
Service Required
E-10 Air Sensor Fault (shorted)
Inope rative Oven
Air sensor is shorted. Air sensor defective?
Detach the sensor from the terminal block. Use an Ohm meter to measure
the resistance of the sensor. Check sensor at 32°F (0°C) using a container of
ice water. If Ohm reading is 100, replace display. If Ohm reading is not 100,
replace sensor.
E-11 Air Sensor Fault (open)
Inope rative Oven
Air sensor is open or connection failure. Air sensor defective?
Detach the sensor from the terminal block. Use an Ohm meter to measure
the resistance of the sensor. Check sensor at 32°F (0°C) using a container of
ice water. If Ohm reading is 100, replace display. If Ohm reading is not 100,
replace sensor.
E-30 Under temperature
