Error

Code Description Possible Cause

E-10 Cavity air sensor shorted Cavity air sensor reading < 5°F. Verify sensor integrity.
See sensor test instructions below.
E-11 Cavity air sensor open Cavity air sensor reading > 517°F. Verify sensor integrity.
See sensor test instructions below.
E-20 Product probe is shorted
Oven will cook in time only
Product probe reading < 5°F. Verify sensor integrity.
See sensor test instructions below.
E-21 Product probe is open
Oven will cook in time only
Product Probe reading > 517°F. Verify sensor integrity.
See sensor test instructions below.
E-30 Under temperature Unit has not reached set-point for more than 90 minutes.
E-31 Over temperature
Unit has been higher than 25°F above the maximum cavity set-point for
more than 2 minutes. Note: Holding Cabinets with this error code are
more than 145°F higher than the maximum set-point.
E-50 Temp. measurement error Contact factory.
E-51 Temp. measurement error Contact factory.
E-60 Real time clock error Data set to factory default. Ensure that date and time are correct if applicable.
E-61 Real time clock error Contact factory.
E-78 Voltage low Voltage below 90 VAC on a 125 VAC unit, or below 190 VAC on a
208-240 VAC unit. Correct voltage.
E-79 Voltage high Voltage over 130 VAC on a 125 VAC unit, or over 250 VAC on a
208-240 VAC unit. Correct voltage.
E-80 EEPROM Error Ensure that all temperatures and times are properly set.
Contact factory if problem persists.
E-81 EEPROM Error Contact factory.
E-82 EEPROM Error Contact factory.
E-83 EEPROM Error Contact factory.
E-85 EEPROM Error All timers, if previously on, are now off. Possible bad EEPROM.
E-86 EEPROM Error Stored HACCP memory corrupted. HACCP Address reset to 1. Possible bad
EEPROM. Contact factory if problem persists.
E-87 EEPROM Error
Stored offsets corrupted. Offsets reset to 0. Control may need a recalibration.
Possible bad EEPROM. Contact factory if problem persists.
E-88 EEPROM Error All timer set-points are reset to 1 minute. Timers, if previously on, are now
off. Possible bad EEPROM.
E-90 Button stuck A button has been held down for >60 seconds. Adjust control. Error will
reset when the problem has been resolved.
E-dS Datakey error Datakey digital signature incompatible. Cycle power, and install compatible
Datakey if error persists.
E-dT Datakey error Datakey incompatible with control. Install compatible Datakey.
E-dU Datakey unplugged Install Datakey and cycle power to control to clear error.
Note: If in doubt, always cycle the power to the control and contact factory if the problem persists.

To test probe and air sensor:

Tes t probe and air sensor by placing sensor in ice water bath and using an ohmmeter set on the ohm scale. The
reading should be 100 ohms resistance. If it is more than 2 ohms higher or lower, sensor needs to be replaced.
