Error Codes

Display	Cause	Solution
E-4A	The cabinet enclosure temperature exceeds 70° C / 158° F for 15 minutes. The system may go into safe mode by turning off all heaters.	Verify vents at the sides of the unit are free from obstruction. Ensure there is no heat source near the unit. No power to or Faulty Fan(s) Bad harnesses from I/O to Fan(s) Faulty I/O Board Temperature Sensor Faulty I/O Board
E-4B	The I/O board heat sink exceeds 80° C. The system may go into safe mode by turning off all heaters.	Faulty Fan(s) Bad connections on Heat Sink clips to plate for the I/O Board. Heat Sync RTD failure. Faulty I/O Board
E-5 Shelf location is indicated	The shelf temperature exceeds the set point by 11° F C ) for more than 15 minutes.	Bad heater probe connections on heater side or I/O Board side Resistance of heater probe faulty
E-6A Heat sink, Shelf top, Shelf bottom	- If an RTD has an open circuit failure then the system will report the E-6A error code. - Error text will indicate either the top shelf probe, bottom shelf probe, ambient or heat sink failure. - Shelf will be disabled from use. - Upon resolution, shelf will be enabled for usage, all product on that shelf will transition to discard status.	Heater probe harness disconnected or broken for top shelf Faulty heater probe for top shelf Heat Sink Probe failure
E-6B Heat sink, Shelf top, Shelf bottom	- If an RTD has a closed-circuit failure or a “short” then the system will report the E-6B error code. - Error text will indicate either the top shelf probe, bottom shelf probe, ambient or heat sink failure. - Shelf will be disabled from use. - Upon resolution, shelf will be enabled for usage, all product on that shelf will transition to discard status.	Heater probe harness disconnected or broken for bottom shelf Faulty heater probe for bottom shelf Heat Sink Probe failure
E-10	Indicate a shelf’s temperature has reached or exceeded the High Limit maximum. Temperature is at or above 230F/110C for at least 1 second.	Damaged or broken harness Faulty heater probe
E-60A	I/O Board loses communication with a Display Board. - Communication loss between the I/O and one of the Display board(s) the I/O board will generate an E-60A error code. New display is not set to primary or secondary.	Turn power off for 30 seconds, and then turn on. Bad communication harness between HMI and I/O Board Faulty Port on HMI Board Faulty Port on I/O Board See Setting Up New Control in Replacing the Control.
E-60B	Display board loses communication with I/O board. (Double Display Units) Communication loss of Display Board or I/O Board. (Single Display Units) - Communication loss between the Display board and the I/O board. New display is not set to primary or secondary.	Turn power off for 30 seconds, and then turn on. Bad communication harness between HMI and I/O Board Faulty Port I/O Board Faulty Port on HMI Board See Setting Up New Control in Replacing the Control.
E-200	I/O board SD card is missing or unable to read / write to SD card.	Reseat SD Card Replace SD Card
E-205	Failure of the system to upload / download settings from a USB drive.	Verify contents are correct on USB Try another USB USB connection or cable issue USB Port issue on I/O Board
E-210	Failure of one of the fans during start up or normal operation.	Run fan test in service menu Faulty fan connection Loss of 24v DC power to fan Faulty Fan Faulty I/O Board
E-211	Fan draws too much current of 4A for longer than 6ms (e.g., stalls).	Run fan test in service menu Faulty fan connection Dirty or Faulty Fan Faulty I/O Board
E-215	Shelf heater temp does not rise to operating temp within 50 minutes +5/-5 F during start-up with uninterrupted power. NOTE: will be an internal only error code (error log indication only at this time).	Check Power Cable Bad heater connection I/O Board or Heat Sync Clip connection Faulty Heater
E-216	Occurs if a shelf heater temp drops 11° F below set point for more than 15 minutes, for a shelf that is at temperature, and set point not recently changed.	Check Power Cable Heater probe connection issue I/O Board or Heat Sync Clip Issue Faulty Heater Probe
E-220	If the I/O board loses communication with both Display UI boards for more than 180 seconds, the system goes into a safe mode by turning off all heaters.	Turn power off for 30 seconds, and then turn on. If recoverable, then continue operation. Bad Display Board connections Bad I/O Board Bad Display Boards
E-220A	If the I/O board senses the loss of network connectivity, the system goes into a safe mode by turning off all heaters.	Turn power off for 30 seconds, and then turn on. If recoverable, then continue operation. Bad connection cable to I/O Board Bad I/O Board Bad Display Board
E-225	Indicate a hardware failure such as inability to read line voltage or current draw from the power monitor IC.	Can continue with operation as long as a E-6A or E-6B does not occur. Faulty power cable Faulty power supply Bad power connections Bad I/O Board
