Troubleshooting
NO PELLETS ARE DELIVERED TO THE CRUCIBLE
Verify that there are pellets in the pellet hopper. Note that it can take up to seven minutes for pellets to travel from the
pellet hopper to the crucible.
IF THIS DOESN’T FIX THE PROBLEM FOLLOW THIS PROCEDURE TO CHECK THAT THE AUGER DRIVE MOTOR
AND INTAKE FAN ARE WORKING.
Make sure the power switch is OFF and the power cord is disconnected.
Remove the controller and the pellet hopper to access the auger drive motor and intake fan connections. See Figure 1 on
the previous page.
Unplug the auger drive motor (orange/white wire pair) and the intake fan (purple/white wire pair). Then reconnect both
connections. See the wiring diagram near the end of this manual.
Plug the power cord into an appropriate grounded electrical outlet and turn the power switch ON.
If the auger drive motor is working, the digital controller may need to be replaced.
If the auger drive motor is not working, but the intake fan is working, the problem is the auger system which may need to be
checked.
• Turn the power switch to OFF.
• Locate the small fan blade on the back of the auger drive motor.
• Turn the power switch to ON and watch to make sure the fan blade turns. If it doesn’t turn it may need to be
replaced. If it turns a bit and then stops, turn the power switch to OFF and see if it unwinds slightly, indicating
a jam that needs to be cleared.
NO PELLETS ARE DELIVERED TO THE CRUCIBLE
IF FOREIGN OBJECTS OR WET PELLETS JAM THE AUGER SYSTEM, THEY WILL NEED TO BE
REMOVED AND CLEARED.
Make sure the power switch is OFF and the power cord is disconnected. Remove the pellet hopper to access
the auger drive motor. See Figure 1 on the previous page.
Remove the bolt and nut connecting the auger drive motor shaft to the auger shaft and the screw holding the
auger retainer to the auger tube. See Figure 2 on the following page.
With a small pipe wrench or locking pliers on the auger shaft turn the auger counter clockwise. It will be hard
to turn until it breaks free.
Remove the auger and clean all pellets, ash or foreign objects from the auger, auger tube and crucible. A
shop-vac is helpful.
Sand the outside surfaces of the auger with medium grit sandpaper. Sand the inside of the auger tube if
necessary. Vacuum sanding grit out of the auger tube and crucible when finished.
Reinstall the auger bushing and the auger into the auger tube, making sure the auger rotates freely. Re-attach
the auger shaft to the auger drive motor shaft. See Figure 2 on the following page.
