HEr High
Temperature Error

OPERATING WITH
GRILL LID OPEN FOR
TOO LONG CAUSING
FIRE POT TO BE TOO
FULL OF PELLETS
If the grill is operated with the lid open for an extended period of
time at a high temperature setting, the set temperature will not be
reached and too many pellets may be delivered into the fire-pot.
Once the lid is shut the temperature can shoot up to very high
levels (too many pellets burning) causing a high temperature error.
• Switch the grill OFF and turn the Controller Dial to Shut Down.
• Immediately turn the power switch back ON, open the lid and set
to Smoke.
• Wait until the “roaring” sound is heard, close the lid and set to the
desired temperature.
• Avoid opening the lid for longer than required to manage your
cooking.
LOOSE
TEMPERATURE
SENSOR
CONNECTION
Or
FAULTY GRILL
TEMPERATURE
SENSOR
If the HEr error is happening when the grill is NOT very hot it may be
a loose temperature sensor connection or faulty temperature
sensor.
• Check the sensor plug located between the grill drum and hopper.
• Check the sensor connection into the back of the controller (with
the grill power unplugged)
• If still getting HEr contact Z Grills customer support for a
replacement temperature sensor.
Incorrect Grill
Temperature
DIRTY TEMP SENSOR
• Clean the Grill Temperature Sensor to ensure accurate
temperature readings.
FAULTY
CONTROLLER
or
FAULTY
TEMPERATURE
SENSOR
• If the temperature is consistently different to the setting on the
temperature dial the controller may be faulty. Compare the grill
probe temperature to a food probe (plugged into the controller)
located next to the grill temperature sensor. If the grill
temperature is consistently showing a higher/lower temperature
(Eg. always 20
o
C higher) it is most likely a faulty temperature
sensor.
• It is normal for the grill temperature to cycle above and below the
setting by as much as 20
o
C, especially during the initial heat up
phase.
TOO MUCH ASH
• Accumulated ash around the ignition rod can prevent or delay
ignition of the wood pellets results in high temperatures when
they finally ignite.
• Vacuum out the fire-pot after each 5kg of pellet usage.
WEATHER TOO HOT
• During hot, sunny weather the grill may exceed the temperature
setting. Place the grill in a shaded area.
• Open the lid to allow the temperature to drop to the set
temperature level, then close the lid.
LID OPEN TOO MUCH
• Avoid opening the lid too often or for too long as this will cause
larger temperature swings. The controller will read lower
temperatures (particularly when on higher temperature settings)
than the setting and deliver too many pellets.
