F.2.6. Error Messages And Troubleshooting
Problems beyond the routine maintenance would probably involve the refrigeration system or the control system.
It is recommended to contact the factory for assistance if this should occur. Note that the warranty would be voided if
these components are serviced by other than trained technicians approved by the manufacturer.
Here is an error message and troubleshooting procedure list that may occur.
Check the doors are tightly closed. If the problem persists call a qualified technician to
check the integrity of the door switch and the door switch connections.
If any of the AIR PROBE N/G messages occur call a technician to check the integrity of the air probe and the air probe
connections.
If DEFROST ON N/G message occurs, call a technician to check the integrity of the
defrost probe and the defrost probe connections.
Note: The defrost cycle is optional, a defective defrost probe won’t affect the chilling cycles.
This screen appears in case of a defective food probe. The defective food probe does
not give any reading. Call a technician to check the defective food probe and the
probe’s connections.
Note: In case of defective food probes, the unit will operate normally in Manual cycle.
Check if the printer’s power LED is on. If it is not, press the printer’s power button to
turn it on. For more details read the printer manual. If the problem persists call a
technician to check the printer.
This message appears when the air temperature in the cabinet is above the preset
high limit or below the low limit. The controller will turn the unit off. The unit will have to
be restarted.
Note: The above problem will occur if the unit is overloaded with extremely hot food. If this is the case, open the cabinet,
let it cool, and restart the unit after a few minutes. If the problem persists, call a refrigeration technician.
