Probable Causes
Incorrect display option programmed.
Vat ID locator connector unplugged
from rear of touch screen or grounded
position in control box.
All menu groups have been deleted.
Filter error has occurred, filter pad
clogged, 24-hour filter pad change
prompt has occurred or change filter
pad was ignored on a prior prompt.
Frypot temperature is more than 410ºF
(210ºC) or, in CE countries, 395ºF
(202ºC).
Frypot temperature is high enough to
open the physical bi-metallic high limit
switch or the switch has failed.
Failed high limit.
Controller in high-limit test mode.

Failed high limit.
A. Filter pan is not fully inserted
into fryer.
B. Missing filter pan magnet.
C. Defective filter pan switch.
Frypot temperature is below 180°F
(82°C).
Frypot temperature is above 180°F
(82°C).
A. Problem with the temperature
measuring circuitry including the
probe.
B. Bad Connection
A. Heat or latch circuit failed.
B. SIB failure
Press home button. Press Service button. Press Service
button again. Enter 3000. Press Tech Modes. Press Toggle to
Select. Press F° to C° to toggle temperature scale. Press YES to
confirm. Press check to complete. Press home to exit.
Ensure that the vat locator connector is properly connected to
touch screen harness and ensure that ground on harness is
properly grounded to control box.
Create a new MENU group or reload menu files. Once a new
menu is created, add recipes to the group (see section 4.11 of
the IO manual).
Change the filter pad and ensure the filter pan has been
removed from the fryer for a minimum of 30 seconds.
Do NOT ignore CHANGE FILTER PAD prompts.
This in an indication of a malfunction in the temperature
control circuitry, including a failure of the high-limit
thermostat during normal operation.
This is displayed when the oil temperature is above 425°F
(218°C) and the high-limit thermostat has opened, halting the
heating of the oil. Let the high limit cool to determine if the
switch closes. Check high limit resistance.
This is displayed to indicate the high limit has failed.
This is displayed only during a test of the high-limit circuit and
indicates that the frypot temperature is more than 410ºF
(210ºC) or, in CE countries, 395ºF (202ºC).
This is displayed only during a test of the high-limit circuit and
indicates that the high-limit has opened properly.
This is displayed during a test of the high limit to indicate the
high limit has failed.
A. Pull filter pan out and fully reinsert into fryer.
B. Ensure the filter pan magnet is in place and if missing
replace.
C. If the filter pan magnet is fully against the switch and
controller continues to display INSERT PAN, switch is
possibly defective.
This display is normal when the fryer is first turned on while in
the melt cycle mode. To bypass the melt cycle press BYPASS
MELT CYCLE button next to the PREHEAT.
displays PREHEAT while heating to setpoint. If the display
continues, the fryer is not heating.
This display is normal when the fryer is above 180°F (82°C) but
below setpoint. If the display continues, the fryer is not
heating. Clean the float switch sensor. Ensure when removing
the float switch that its position is clearly marked and replaced
properly. Installing the float upside down will change the
switch from N/O to N/C. This could allow the empty frypot to
ignite.
A. This indicates a problem within the temperature
measuring circuitry. Check resistance of probe, if faulty
replace probe.
B. Ensure temperature probe is connected properly to SIB
board. Ensure that the connector is terminated properly.
A. Check the heat or latch circuit.
B. Replace the SIB board.
