|
“E-5” |
Oil Overheating |
Turn switch to OFF position, then turn switch back to ON; if display shows “E-5”, the heating circuits and temperature probe should be checked |
|
“E-6A” |
Temperature probe open |
Turn switch to OFF position, then turn switch back to ON; if display shows “E-6A”, the temperature probe should be checked |
|
“E-6B” |
Temperature probe shorted |
Turn switch to OFF position, then turn switch back to ON; if display shows “E-6B”, the temperature probe should be checked |
|
“E-10A” “E-10B” “E-10C” “E-10D” “E-10F” “E-10M” “E-10Y” |
High limit tripped above 300° F High limit tripped below 300° F High limit tripped while cooking High limit tripped within 5 minutes after self-detected that vat had refilled. High limit tripped filtering or any use of filter menu option High limit tripped during melt mode (exit melt at 180°F) High limit tripped less than 5 minutes after user responded “YES” to an “Is Pot Filled?” question |
Allow unit to cool (15-20 minutes) and reset high limit by pressing down and releasing raised side of the switch for the vat that is not operating; switches are located behind right door next to JIB.; if high limit does not reset, high limit must be replaced |
|

Left level sensor open Right level sensor open Both level sensors open |
Turn switch to OFF position, then turn switch back to ON; if display still indicates a failed sensor, have the connectors checked at the control board; have sensor checked & replace if necessary |
|
“E-20-A” “FAN SENSOR STUCK CLOSED” |
Pressure switch failure/ Wiring problem | If fan is not running, have pressure switch checked; should be open circuit, if no air pressure If fan is running, wiring error |
|
“E-20-B” “NO DRAFT” “CHECK FAN” |
Pressure Switch failure/ hose loose Draft Fan failure/ low voltage/ Flue or hood obstruction |
Press power button to vat off and back on again, if E-20-B persists, have pressure switch checked; should be open circuit if no air pressure; make sure hose is connected to fan and pressure switch Have draft fan checked; low voltage going to fan Check the fryer flue and hood system for obstructions |
|
“E-20-D” “IGNITION” “FAILURE” |
Failure to ignite/ no flame sense | Press power button to vat off and back on again, if E-20-D persists, check gas line connections; check gas shutoff valve; check ignition module; check gas valve; check flame sensor gap; check gas valve, and check ignition module wiring |
|
“E-21” |
Slow heat recovery |
Have a certified service technician check the fryer for correct voltage to the unit; have the contactors and heating element checked; have unit checked for loose or burnt wires |
|
“E-22” “NO HEAT” |
Burner not igniting | Have gas valve and heat circuit checked |
|
“E-41”, “E-46” |
Programming failure |
Turn switch to OFF, then back to ON; if display shows any of these error codes, have the controls re-initialized; if error code persists, have the control board replaced |
|
“E-47” |
Analog converter chip or 12 volt supply failure |
Turn switch to OFF, then back to ON; if “E-47” persists, have the I/O board, or the PC board replaced |
|

Temperature input error |
Turn switch to OFF, then back to ON; have control PC board replaced if “E-54C” persists |
|
“E-60” |
AIF PC board not communicating with control PC board |
Turn switch to OFF, then back to ON; if “E-60” persists, have the 1.5 amp fuse on the AIF PC board checked; have the connector between the PC boards checked; replace AIF PC board or control PC board if necessary |
|
“E-62A” |
Communication Error |
|
|
“E-70C” |
Drain valve jumper wire missing or disconnected |
Have the jumper wire checked on the PC board at drain switch interlock position |
|
“E-82A” |
Selector valve not detected |
Have wiring checked between Selector Valve and AIF board |
|
“E-82B” |
Selector valve failed |
Have the “Home” switch on Selector Valve checked |
| “E-82C” | Selector valve failed | Have wiring checked between the “Home” & “Position” switches and the Selector Valve; Have Selector Valve Motor checked; Have drive chain checked |
| “E-82D” | Selector valve failed | Have the “Home” switch and the “Position” switch on Selector Valve checked |
|
