As the chilly weather sets in, nothing is more frustrating than attempting to start up your pellet stove only to find out that the auger won’t turn on. The auger is an integral component of your pellet stove, as it feeds the pellets into the burn pot, keeping your home warm and toasty.

However, if the auger isn’t functioning properly, it can be a cause for concern for any homeowner. In this article, we’ll explore the common causes of an auger that won’t turn on a pellet stove and the steps you can take to troubleshoot and fix the issue.

Understanding Pellet Stove Auger Functioning: A Brief Overview

Understanding the functioning of the pellet stove auger is essential if you want to fix it when it fails to turn on. The pellet stove auger is a motorized screw-like device that transports the pellets from the hopper into the burn pot. The auger has two critical functions. The first is to deliver the right amount of pellets to the burn pot, while the second is to ensure that the temperature is regulated. The auger works in conjunction with a control panel that regulates the amount of fuel that is delivered into the burn pot.

In a working pellet stove, the auger should turn when the stove is turned on. If the auger fails to turn on, it means that something has gone wrong with the system. There are several reasons why your auger may fail to turn on, but these can be rectified through troubleshooting and repair.

Pellet stoves are highly efficient heating devices that require meticulous attention to detail. If your auger fails to turn on, this article will guide you on how to troubleshoot and fix the problem. The next section of this article will outline the common reasons why your pellet stove auger refuses to turn on.

Common Reasons Why the Auger Refuses to Turn On Your Pellet Stove

If your pellet stove’s auger isn’t turning on when it should, there are several reasons why this could be happening. Here are some of the most common reasons:

1. Dirty or Clogged Auger

The auger on your pellet stove can become dirty or clogged with debris over time. This can prevent it from turning on and cause it to malfunction. To fix this, you’ll need to clean or replace the auger. Make sure to turn off your pellet stove and unplug it before attempting any repairs.

2. Burned Out Motor

Another common reason why your pellet stove’s auger may not be turning could be a burned-out motor. Over time, the motor can become worn and ultimately fail. If this happens, you’ll need to replace the motor to get your pellet stove working properly again.

3. Faulty Thermostat

If your pellet stove’s auger is not turning on, it could be due to a faulty thermostat. The thermostat is responsible for sensing the temperature in the room and adjusting the auger’s speed accordingly. If it’s not working correctly, your auger may not turn on at all. To fix this issue, you’ll need to replace the thermostat.

4. Loose or Broken Belt

Your pellet stove’s auger is connected to a belt that helps it to turn. If this belt becomes loose or broken, it can prevent the auger from turning on. If you notice that the belt is loose or broken, you’ll need to replace it to get your pellet stove working again.

Now that you know some of the common reasons why your auger may not be turning on your pellet stove, you’re ready to troubleshoot and fix the problem. But before you start, make sure to gather all the necessary tools and materials. Let’s take a look at what you’ll need.

Troubleshooting the Pellet Stove Auger: Step-by-Step Guide

If your pellet stove auger is not turning on, there are several things you can do to troubleshoot the problem and get it up and running again. Here is a step-by-step guide to help you diagnose and fix the issue.

Step 1: Check the Power
The first thing you should do is check if the pellet stove is receiving power. Ensure that the power cord is plugged in securely and that you have power in the outlet. If the power supply is not the issue, move on to step 2.

Step 2: Inspect the Auger Motor
Next, inspect the auger motor to see if it is working correctly. Turn off the stove and unplug it from the outlet before inspecting the motor. Remove the access panels and check for any obstructions or debris that might be hindering the motor’s movement. If the motor looks fine, proceed to step 3.

Step 3: Check the Control Board
If the motor is not the issue, check the control board of the pellet stove. The control board is typically located near or on the back of the stove. Check if there are any loose wires, corrosion, or damages on the board. Also, ensure that all wiring is firmly connected to the board.

Step 4: Test the Centrifugal Switch
The centrifugal switch is designed to trigger the auger motor to start rotating. If it fails, the motor will not turn on. Clean the switch and use a multimeter to test the switch`s continuity. If there is no continuity, it is probably faulty, and you need to replace it.

Step 5: Inspect the Pellet Hopper
The pellet stove auger might refuse to turn on if the hopper is empty. Ensure that there are enough pellets in the hopper to sustain the stove. Also, make sure that the pellets are not clumped together as they can block the auger.

By following these troubleshooting steps, you should be able to figure out why your pellet stove auger is not turning on. If you are still uncertain about the problem after following these steps, seek help from a professional HVAC technician.

4. Essential Tools and Materials to Repair Your Pellet Stove Auger

When it comes to fixing your pellet stove auger, having the right tools and materials is crucial. Here are some of the essential items you’ll need:


  • Screwdriver: Depending on your stove’s design, you may need a Phillips or flathead screwdriver to disassemble various parts.
  • Pliers: These will come in handy when you need to remove wires or adjust parts that are hard to reach.
  • Wrench: You may need an adjustable wrench to loosen and tighten nuts and bolts on your pellet stove.
  • Shop Vacuum: To clean out any debris that may be clogging your pellet stove’s auger.


  • Pellets: You’ll need a few pellets to test the auger after making repairs.
  • Lubricant: A spray lubricant can help prevent the auger from jamming in the future.
  • Replacement Parts: Depending on the issue, you may need to replace parts such as the auger motor, auger blade, or auger bushings.

Having these tools and materials readily available can make the process of fixing your pellet stove auger go much smoother. Don’t forget to check your stove’s manual for specific instructions and part recommendations.

Tips for Maintaining Your Pellet Stove Auger and Preventing Future Problems

Now that you’ve fixed your pellet stove auger, it’s essential to learn how to maintain it correctly to ensure its longevity and efficiency. Here are some simple tips that can help you in maintaining your pellet stove auger:

1. Regular Cleaning:

Cleaning your pellet stove auger regularly is essential in preventing future problems. The auger is responsible for transferring the pellets to the combustion chamber, and a dirty auger can impede its function. Hence, clean the auger every two weeks or every time you clean the firebox. You can use a brush or a cloth to clean the auger and remove any debris that might have accumulated.

2. Lubrication:

A well-lubricated pellet stove auger will function smoothly, and the chances of it breaking down are minimal. Lubricate your auger regularly with a high-quality lubricant to prevent any rust or corrosion and improve its lifespan. You can also use a food-grade lubricant, considering the auger’s function in transferring food-grade pellets.

3. Inspect the Auger:

Regularly inspect your pellet stove auger to check for any signs of wear and tear. If you notice any visible damage or cracks, it’s advisable to replace the auger before it causes more significant problems. Additionally, check the auger for blockages, especially if your pellets are of low quality and prone to causing ash buildup.

By following these tips, you can prevent common problems that come with a pellet stove auger. Always ensure that you invest in a high-quality pellet stove auger and purchase pellets that are compatible with your auger to prevent any jamming or blockages. Remember, regular maintenance is essential in ensuring the efficiency and longevity of your pellet stove auger.
