POWER FAILURE DURING USE
Possible Causes
Power goes out during operation.
To restart unit after power outage.
GRILL FEEDS PELLETS, BUT WILL NOT IGNITE
Possible Causes
Bad igniter element.
The control board is not sending power to the igniter.
GRILL WILL NOT FEED PELLETS
Possible Causes
Thermocouple is defective.
Bad Auger Motor.
Auger Jam.
Loose wire or connector.
Bad control board.
WARNING: Never leave the grill unattended while operating.
Disconnect the grill from its power source when not in use.
Troubleshooting
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.
Possible Remedies (Unplug grill first when possible)
Wait for the grill to cool for about 30 - 45 minutes. Check the
thermocouple to see if it's bad. Check resistance with volt
meter.
Remove the two retaining screws in the service panel and
swing out of the way. Remove the auger motor from the auger
shaft and try to run the unit. If the motor will turn, the shaft is
jammed on something. If the motor will not turn, the motor is
bad.
Start by emptying the hopper. Then remove the auger motor
by removing the auger pin. Remove the two screws holding
the auger bushing. Gently pull the auger shaft straight out so
that the end of the auger shaft comes out. After you have
removed the shaft, inspect it for bent flights, burrs, or broken
welds. Remove any foreign material that might have caused
the jam. Also, check the auger tube for signs of damage such
as burrs, rough spots, or grooves cut into the metal that could
have caused a jam.
Check all wires and connectors that connect to the auger
motor, thermocouple, and the fan.
If the fuse is good, the wires and connectors check out good,
and the high limit switch did not trip, test for power going to
the auger motor. If there is not a full current going to the auger
motor when the fuel feed light is on, you have a bad control
board.
