Error		Possible Cause
Code	Description/Results	Service Required
E-10	Air sensor fault (shorted)	Air sensor is shorted or defective, or there is a connection failure.
		See following page for air sensor test.
E-11	Air sensor fault (open)	Air sensor is open or defective, or there is a connection failure.
		See following page for air sensor test.
E-20	Ov e n w ill co o k in tim e o nly	Product probe is shorted or defective, or there is a connection failure.
		See following page for probe sensor test.
	Product probe fault (shorted)
E-21	Ov e n w ill co o k in tim e o nly	Product Probe is open, defective, or there is a connection failure.
		See following page for probe sensor test.
	Product probe fault (open)
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, does not contain
		frozen products, and is not overloaded. 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-50	Temperature sensor chip 1	Contact service.
	is not responding.	Contact service.
E-51	Temperature sensor chip 2
	is not responding.	This is likely caused by the unit having been unplugged for an extended
E-60	Real time clock error
		amount of time. The data stored in the Real-Time Clock has been reset to
		the factory default values. Beeper volume will default to on, and the
		temperature scale will default to °F. Turn main breaker to the unit off for
		10 seconds and then restore power. Contact service if problem persists.
E-61	Real time clock chip is	Contact service.
	not responding.	Check control connections for loose wires. If none, control must be replaced.
E-70	Configuration connector error
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	Function data values were reset.	Ensure that all temperatures and times are properly set.
		Contact service if problem persists.
E-81	Internal control calibration error	Contact service.
E-82	Internal control calibration error	Contact service.
E-83	EEPROM is not responding	Contact service.
E-84	EEPROM - Unit ID error	Contact service.
E-86	EEPROM - HACCP address error	If using HACCP, the unit’s address has been reset to 1. Ensure that your
		oven is set to the correct address (1-247). Contact service if problem persists.
E-87	Calibration offset error	Sensor calibration values corrupted. All offsets reset to 0. Re-calibrate oven
		cavities. Contact service if problem persists.
E-90	Button stuck	A button has been pressed for >= 60 seconds. This error will auto-reset
		when there is no button stuck, remove control and check all button
		functions, align control properly.
E-dS	Datakey signature bad	Datakey incompatible with control. Incorrect or corrupt data key installed
		on control. Replace Datakey with correct key for control and test.
E-dU	Datakey unplugged	The data key is not being seen by the control. Install data key and test
		operation. Contact service if problem persists
