ERROR MESSAGES/TROUBLESHOOTING
DISPLAYED
MESSAGE
MEANING
POSSIBLE CAUSES
POSSIBLE SOLUTION
GRILL PROBE
ERROR
Error for grill temperature
sensor
Wrong sensor type
Poor termination
Controller not setup for gas OR electric
Open or damaged sensor
Sensor is set below or above the
controller operating range
Identify sensor as “ungrounded type”
Review wiring instructions
Check confi guration
Continuity check
Is high limit device activated?
PLATEN PROBE
ERROR
Error for platen
temperature sensor
Wrong sensor type
Poor termination
Controller not setup for gas OR electric
Open or damaged sensor
Sensor is set below or above the
controller operating range
Identify sensor as “ungrounded type”
Review wiring instructions
Check confi guration
Continuity check
Is high limit device activated?
ERROR AMBIENT
Too low or too high
temperature at the
controller
Ambient is lower than 32 deg F or higher
than 176 deg F
Check ventilation of controller area
ERROR COLD
START
EEPROM response issue
EEPROM initializing for the very fi rst time
EEPROM malfunction
Wait for 30 seconds for message to disappear
If message fails to clear controller is suspect
CHECK REED
SWITCH
USE FLAT COOK
Platen failed to calibrate,
can cook in fl at mode
Either of the two reed switches are closed
when they should be open
Reset reed switch positions in calibration menu
CHK PLATEN
LEVEL
Warning that platen level
needs checked
Calibration diff erence between the front
and rear reed switch is greater than the
REED SWITCH MIN but less than the REED
SWITCH MAX in the calibration menu
Recalibrate reed switches in the calibration menu
PLATEN NOT
LEVEL
Platen not level
Calibration diff erence between the front
and rear reed switch is greater than the
REED SWITCH MAX
Recalibrate reed switches in the calibration menu
ERROR DOWN
Platen fails to move down
or is not moving within
40 seconds
Encoder cable not attached
Platen movement obstruction
Motor malfunction
Motor control board malfunction
Check pin connection on motor control board
Remove utensils, check exhaust hood clearance, check
for grease build up on shafts
Check voltage to motor
Check voltage to motor control board
ERROR UP
Platen fails to move up or
is not moving within 40
seconds
Encoder cable not attached
Platen movement obstruction
Motor malfunction
Motor control board malfunction
Check pin connection on motor control board
Remove utensils, check exhaust hood clearance,
check for grease build up on shafts
Check voltage to motor
Check voltage to motor control board
ERROR COMMS
Communication problem
between motor control
and main controller
Controller does not detect 3 consecutive
commands from motor control board
Check cable connection on both boards and voltage
to motor control board
IGNITION
FAILURE
Burner fl ame not
detected
Gas not turned on to grill
No spark from ignitor
Blower malfunction
Air switch malfunction
Gas valve not opening
Ignition module malfunction
Air still in the gas line when reconnected
Check gas valve on supply line and hose connection
Check ignitor wire connections
Check voltage at blower motor
Check voltage at switch, check for pinched air hose
Check voltage at valve listen for valve operation
Check voltage at inputs & outputs of ignition module
Retry by cycling controller off and on
HIGH TEMP
PLATEN/GRILL
Platen or grill platen
temperature is higher
than 465 deg F
Probe calibration not correct
Operational procedures not being
followed (e.g. no scraper and squeegee)
Stuck closed solid state relay
Gas pressure too high
Recalibrate temperature zone
Review procedures when message is displayed
Check for lit LED on Solid State Relay that should be off
Check that manifold pressure is 3.5” W.C.
Allow temperature to cool before operation
