The auger motor is a device that is connected to the spiral auger.

It feeds wood pellets from the hopper through a feed tube into the fire-pot at a slow rate.

The Pellet grill auger stops feeding the pellets halfway

 Main Causes for Z grill Auger Not Turning

Initial start-up of the grill

If you recently buy Z pellet grill, you may encounter an issue that the grill auger not turning in the  initial start-up.

It takes a time to get the auger fully loaded with wood pellets during the initial start-up of your grill.

Typically, the auger won’t turn when you start the grill for the first time.

Auger gets jammed

If you find that your grill auger not turning, it means it gets jammed

The Z grill auger may get clogged due to the following reasons.

Foreign objects stuck in the auger shaft

There are foreign objects in the auger that may cause the auger to get jammed.

If there is any foreign object in the pellets, it may go inside the hopper while filling the pellets into the hopper.

It will reach into the auger through the pellet hopper.

Once this foreign object goes into the auger and it clogs the auger tube.

The contamination from a hard foreign object leads to the auger getting jam.

Sometimes also the small screw or nail gets into the pellet hopper and it goes into the auger.

Finally, it clogs the auger.

Moist pellets

The wet pellets cause the auger jam. If there is enough water on the grill and it goes into the hopper, the wood pellets inside the hopper get wet.

Once the wood pellets get wet located inside the hopper, it turns into sawdust.

When sawdust sits into the auger for longer, it eventually dries up.

This sawdust becomes very hard.

The auger cannot push the hard sawdust and so the auger won’t turn.

Once the pellets are contacted with humidity, they swell up and cause an auger jam.

If the auger gets stuck with these moist pellets, it won’t able to feed pellets into the fire-pot.

Sometimes the wet pellets become hard like concrete and you need to extract them manually.

Burnt/ faulty Auger motor

Sometimes the auger won’t turn because of auger motor burnout.

The auger motor burns due to various reasons such as a jammed auger or another component fault.

If the auger shaft is moving freely, but it is not rotating, there is a possibility of the auger motor issue.

It will expel a burning plastic smell if the auger motor gets burnt out.

You should inspect the auger motor for any visual damage.

If the auger motor gets burnt out, you will notice brown discoloration on the motor windings or the cables.

Sometimes the auger motor is itself is faulty, so that auger won’t turn.

Because of the dead auger motor, the auger won’t work at all.

So, in both the cases such as a burnt auger or faulty/dead auger, you need to replace the whole auger motor.
