Error Codes:
If an error is detected, the system will perform the
normal shutdown procedure regardless of the er-
ror value. The system cannot run while an error is
present. If an error has been detected, it can be
cleared by pressing the On / Off button to enter
the Run Mode. However, if the cause of the error
is still present it will enter the Error Mode again.
ER-1 –
Over Temperature Error – This error can
be detected at any time, and simply means the
Grill Probe temperature exceeded 600°F. This
can also be a sign of an open connection be-
tween the grill control and the Grill Probe.
ER-2 – Failure to Start Error –
Occurs when the
ignition procedure fails to increase the tempera-
ture above 160°F within a 30 minute window.
ER-3 – Power Failure Error –
Occurs when the
system is in the Run Mode and power is lost.
When power is reapplied if the system detects
a temperature of less than 160°F, the assump-
tion is that power was lost and the fi re went out
while power was removed. It does not attempt to
re-light the grill in this case. If power is re-applied
before the temperature falls, the system will
return to the last set point and continue the Run
Mode normally.
ER-4 – Grill Probe Short Circuit –
Occurs when
the system detects a shorted Grill Probe that can-
not be used to reliably measure temperature
