Pellet Stove Augers & Auger Motors (Your Complete Guide)

What Is An Auger On A Pellet Stove?

In a pellet stove, the auger is a screw-like device with a motor at one end that is typically long in length. Using a motor to turn the auger screw at a low RPM speeds up the movement of pellets.

Where Is the Auger On A Pellet Stove?

A pellet stove’s auger is found in the hopper, usually on the front edge of the container’s front wall. The auger motor is usually found at the bottom of the auger screw, and the top of the auger can be seen from inside the combustion chamber through the pellet chute.

When looking into the hopper from the hatch above, the auger is visible on the front-facing side of our pellet stove’s container.

The auger at the base of the hopper of a pellet stove can be seen here.

For the most part, an auger screw is hidden behind a plate that helps keep the pellets inside the auger in place. The screw is essentially invisible.

To collect pellets from the auger’s bottom, the bottom area of the screw auger will be left open.

When looking up the pellet chute from the burn pot in the combustion chamber, depending on the model of your pellet stove, you may be able to see the top of the auger screw.

What Does The Auger Do On A Pellet Stove?

With the auger, pellets are conveyed from the hopper to the burn pot inside the combustion chamber. To keep burning and generating heat, a pellet stove fire requires pellets as fuel. As a result, a pellet stove auger feeds the fire with pellets at the fastest possible rate.

How Does A Pellet Stove Auger Work?

Pellet stove augers collect pellets from the hopper’s bottom and deliver them to the burner’s burn pot within the combustion chamber, which is where they burn. Using the auger motor, pellets are fed into the top of the auger, where they are discharged into the fire via the pellet chute.

Parts Of A Pellet Stove Auger

The auger and auger motor are the two main components of a pellet stove auger, and the auger is usually covered by a collar. Pellet stove auger motors and collars are typically found in the hopper, while pellet stove augers are typically found at the lower end of the auger.

An auger for a pellet stove is made up of the following major components:

  • Auger
  • Auger motor
  • Collar

As the auger rotates, pellets are pushed up the auger by a long screw.

The auger is propelled by an auger motor. The auger’s motor will be at one end of the auger, and in our particular stove model, it can be seen through the back of the stove on the underside of the auger, just under the hopper.

The collar acts as a housing for the pellets inside the auger and helps keep them there.

While the collar is supposed to go over the entire length of the auger, there is an opening at the bottom of the hopper inside our pellet stove where the pellets can be picked up and used.

Troubleshooting Pellet Stove Augers

Pellet Stove Auger Not Working

When it comes to pellet stoves, augers are essential components that move pellet fuel from the hopper to the burn pot while also maintaining a precise fuel-to-air ratio.

An issue with the components themselves or, more commonly, pellets and/or pellet dust jamming the auger can cause pellet stoves to have problems and stop working.

How Do I Know If My Pellet Stove Auger Is Bad?

Blockage in the pellet stove auger or a failing auger component like the motor can cause a pellet stove fire to go out, a pellet stove to shut off, or a pellet stove to not produce as much heat as it should due to an imbalance in the fuel to air ratio.

Pellet stove auger noises that are different from what you’re used to hearing can indicate a problem is developing.

How Do You Fix The Auger On A Pellet Stove?

Cleaning the auger and/or hopper can often fix pellet stove issues caused by an auger problem; this should be done on a regular basis to reduce the likelihood of problems arising in the future. The auger motor may need to be replaced if a more serious problem occurs.

How Do You Remove The Auger From A Pellet Stove?

When working with a pellet stove, the auger can be accessed by removing the back or side panels. Remove the auger motor from the bottom of the auger and the cover from the auger housing inside the hopper to remove the auger housing cover. Remove the auger bushing plate and the auger screw by removing these two components from the auger.

Here’s an instructional video on how to remove a pellet stove’s auger.

Some augers are more difficult to get to than others. Models may or may not have an auger access cover where the auger can be seen, depending on the stove.

Unclogging The Auger In A Pellet Stove

Pellet stove augers are prone to jamming, which is the most common issue.

To aid in pellet stove auger unclogging, use the following methods:

  • Feed the auger manually in the beginning if you can.
  • Make sure the hopper is free of pellets and dust before using it.
  • Make sure the pellet chute is clean.
  • Make sure the auger is clean.
  • Get the stove checked out by a professional.

The following video shows how a jammed pellet stove auger can be cleaned.

Testing The Auger Motor In A Pellet Stove

The auger motor in a pellet stove can malfunction, resulting in an auger problem.

The auger motors in pellet stoves can be tested to see if they are working properly and to help identify the problem.

The following procedures can be used to test a pellet stove auger motor:

  • If at all possible, try to feed the auger manually.
  • Testing for power by removing the auger motor and reinstalling it.
  • An attempt will be made to halt the rotation of the auger output shaft.
  • Not having power means trying to turn the auger motor by hand.

This video shows you how to test a pellet stove’s auger motor.

Pellet Stove Auger Making Noise

A noisy pellet stove auger may indicate a problem with the bearings, the auger motor, or even the auger. If the noise is coming from the auger or hopper, check first for obstructions or problems with the parts.

Pellet stove auger noises are frequently the result of a blockage, so be sure to thoroughly clean the auger and hopper before using your stove again.

It’s possible that the motor is causing the noises if they continue to occur.

For reference, listen to the auger motor in a pellet in the video below.

Pellet Stove Auger Replacement

If you want to get the most out of your pellet stove, you should replace worn-out parts like the auger or motor as they wear out. This will help your pellet stove run longer.

In most cases, a pellet stove’s maker will provide information on what replacement parts are available for a specific model.

A gear motor for the auger or a complete auger set is described in the owner’s manual for our pellet stove as an illustration.
