GRILL ENTERS SHUTDOWN MODE UNEXPECTEDLY
Possible Causes
The convection blower is overheating and
tripping the internal temperature shutoff
Fuel other than wood pellets is being
burned in the grill
Power surge or brown out situation
Thermocouple is malfunctioning
AFTER GRILL HAS BEEN ON FOR A WHILE, THE BURN POT OVERFILLS
Possible Causes
Grill is dirty, which restricts airflow
through the burnpot
Burnpot holes are blocked
Blockage in air intake pipe
Combustion blower is not spinning fast
enough
Bad Pellets
POWER FAILURE DURING USE
Possible Causes
Power goes out during operation
Restarting the unit after a power outage
GRILL FEEDS PELLETS, BUT WILL NOT IGNITE
Possible Causes
Bad igniter element
The control board is not sending power to
the igniter
Possible Remedies (Unplug grill first when possible)
Clean any dust off of the windings and fan blades. If oiling the blower does
not help, the blower may be bad.
This pellet grill is designed and tested to use cooking wood pellets. Check
for signs of fuel other than wood pellets. No other types of fuel have been
approved for this pellet grill. If there are signs of other types of fuel being
used, stop using them immediately.
A power surge, spike, or voltage drop could cause the thermocouple to
malfunction. Use a surge protector
If the other items check out good, replace the thermocouple.
Possible Remedies (Unplug grill first when possible)
Follow all cleaning procedures in the "Maintenance" section of the
owner's manual.
Remove the burnpot and thoroughly clean it.
Visually inspect the air intake that leads into the burnpot for foreign
material.
Clean fan blades and inspect bearings for wear. Ensure the fan is free of
any obstructions.
The brand of pellets or the batch of pellets that is being used may be of
poor quality. If possible, try a different brand of pellets. It is advisable
to try a brand that is made from a different type of wood (softwood vs.
hardwood). Different woods have different characteristics when being
burned.
Possible Remedies (Unplug grill first when possible)
Observe the grill to make certain unsafe burning conditions do not occur
during the outage.
Press the power and the prime button at the same time to resume
standard operation.
Possible Remedies (Unplug grill first when possible)
Put power directly to the igniter element. Watch the tip of the igniter from
the front of the grill. After about 2 minutes the tip should glow. If it does
not, the element is bad.
Check the voltage going to the igniter during startup. It should be 110-
115 volts. If the voltage is lower than full voltage, check the wiring. If the
wiring checks out good, the board could be bad.
