Error
Code Description/Results
Possible Cause
Service Required
E-10 Air Sensor Fault (shorted)
Air sensor is shorted or defective, or there is a connection failure.
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)
Air sensor is open or defective, or there is a connection failure.
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
The unit has been below its set temperature for 90 minutes. Check the
following: Oven door may be open or door gasket may need replacement.
Verify that the oven has been preheated and is not overloaded or contains
frozen products. Air sensor, probe, or relay may be defective, there may be a
bad wire connection, an open heating cable, or the high limit switch may be
tripped. Contact service if problem persists.
E-31 Over temperature
This error will display if the unit reaches a temperature of 25 degrees above
its maximum allowable set point. If the unit reaches 50 degrees above its
maximum allowable set point the control will turn off. Check the following:
Shorted cable, defective solid state relay, or defective air sensor. If none of
the above, contact service.
E-80 Function data values were reset.
Ensure that all temperatures and times are properly set. Contact service if
problem persists
E-82 Internal control calibration error
