Understanding the Auger Motor

The auger motor is an essential component of a pellet stove. It is responsible for feeding pellets from the hopper into the burn pot. The motor consists of a gearbox, motor, and auger. The motor drives the auger, which moves the pellets from the hopper to the burn pot. The gearbox is used to adjust the speed of the auger.

Tools Required for Testing the Auger Motor

Before you start testing the auger motor, you will need a few tools. These include a voltmeter, a continuity tester, and a screwdriver. A voltmeter is used to measure the voltage output of the motor. A continuity tester is used to check the continuity of the motor’s windings. A screwdriver is needed to remove the motor from the stove.

Steps for Testing the Auger Motor

Step 1: Turn off the Pellet Stove

Before you begin testing the auger motor, turn off the pellet stove and unplug it from the power source. This will ensure your safety while working on the motor.

Step 2: Access the Auger Motor

Locate the auger motor in your pellet stove. It is usually located at the back of the stove, near the hopper. Use a screwdriver to remove the motor from the stove.

Step 3: Test for Continuity

Using a continuity tester, check the continuity of the motor’s windings. Touch one probe to the motor’s positive terminal and the other to the negative terminal. If the tester beeps, it means the motor’s windings are intact. If it does not beep, the motor’s windings are broken, and the motor needs to be replaced.

Step 4: Test for Voltage Output

Using a voltmeter, measure the voltage output of the motor. Connect the voltmeter to the motor’s positive and negative terminals. Turn on the pellet stove and set it to the highest setting. If the motor does not receive any voltage, it means there is a problem with the wiring or control board. If the motor receives voltage but does not turn, it means the motor is faulty and needs to be replaced.

Step 5: Reassemble the Auger Motor

Once you have tested the motor, reassemble it back into the pellet stove. Ensure that all the screws are tightened properly.

How do you know if auger motor is bad on a pellet stove?

If the pellets are not feeding into the burn pot, or if the stove is not igniting or burning efficiently, it may be a sign that the auger motor is not functioning properly. You may also hear unusual noises coming from the motor, or the motor may not turn at all. In these cases, it is best to test the motor using a voltmeter and continuity tester to determine if it needs to be replaced.

How do you check an auger on a pellet stove?

To check the auger in a pellet stove, you will need to remove it from the stove and inspect it for any signs of damage or wear. Check the motor and gearbox to make sure they are properly lubricated and not damaged. You can also test the auger using a continuity tester to ensure it is functioning properly. If you notice any issues or suspect that the auger is not working correctly, it may be time to replace it.

Why is my auger not turning in my pellet stove?

If your auger is not turning in your pellet stove, there could be several possible causes. One of the most common reasons is a faulty auger motor. However, it could also be due to a clogged or jammed auger, a broken or loose drive belt, or a malfunctioning control board. To determine the exact cause, you will need to inspect the motor, auger, drive belt, and control board, and perform necessary repairs or replacements.

What voltage is a pellet stove auger motor?

The voltage of a pellet stove auger motor typically ranges from 115 to 120 volts AC. However, the exact voltage may vary depending on the specific model and manufacturer. It is important to check the specifications of your pellet stove and auger motor to ensure you use the correct voltage when testing or replacing the motor. Using the wrong voltage can damage the motor or other components of the pellet stove, so it is essential to exercise caution and follow manufacturer instructions when working with electrical components.

How long do pellet stove auger motors last?

The lifespan of a pellet stove auger motor depends on several factors, including the quality of the motor, frequency of use, and maintenance. On average, a well-maintained auger motor can last between 3 to 5 years. However, some motors may last longer, while others may fail sooner. Regular maintenance, such as cleaning the motor and ensuring proper lubrication, can help extend the lifespan of the auger motor.

What controls the auger on a pellet stove?

The auger on a pellet stove is typically controlled by a control board that regulates the speed and direction of the motor. The control board receives signals from the thermostat and other sensors that monitor the temperature and other conditions in the stove. Based on these signals, the control board adjusts the speed of the auger motor to maintain the desired temperature in the stove. Some pellet stoves may also have manual controls that allow you to adjust the speed and direction of the auger motor manually.


How can I test the auger motor in my pellet stove if it’s not working?

Use a multimeter to check for continuity in the motor’s wiring and ensure it receives power. Replace if necessary.

Is there a specific sound the auger motor should make when functioning correctly?

Yes, a consistent humming or buzzing noise indicates normal operation. Unusual sounds or complete silence may suggest a problem with the motor.

What should I do if the auger motor is not turning or has irregular movements?

Inspect for obstructions in the auger mechanism and ensure it moves freely. Lubricate if needed. If problems persist, consider replacing the motor.

Can I visually inspect the auger motor for issues without specialized tools?

Yes, look for signs of damage, wear, or burnt areas on the motor. Check for loose connections or debris around the auger.

Are there any safety precautions to take when testing the auger motor in a pellet stove?

Ensure the stove is turned off and unplugged before testing. Exercise caution while handling tools and troubleshooting electrical components to avoid accidents.


Testing the auger motor in your pellet stove is an important task that should be performed regularly to ensure the stove is functioning efficiently. By following the steps outlined in this blog post, you can easily test the auger motor using basic tools like a voltmeter, continuity tester, and screwdriver. Remember to always turn off the stove and unplug it before starting any work on the motor, and if you are not comfortable performing the replacement yourself, it is best to hire a professional. By maintaining the auger motor and ensuring it is working correctly, you can enjoy the benefits of a warm and efficient pellet stove for years to come.
