If it fails, your stove cannot produce heat, and you may see error messages or hear unusual noises. Understanding why the auger fails and how to fix it can save you time, money, and stress.
In this guide, you’ll learn how the Pelpro auger works, what causes it to stop, and practical steps to troubleshoot and fix the problem. Whether you are a new user or have years of experience, these insights will help you get your stove running smoothly again.
You will also discover lesser-known tips, expert advice, and clear answers to common questions about auger problems.
Understanding The Pelpro Auger System
The Pelpro auger is a motor-driven spiral shaft that moves wood pellets from the hopper into the combustion chamber. This process is essential for maintaining a steady fire and regulating heat output. The auger is controlled by the control board, which decides when and how long the auger should run based on temperature settings and safety sensors.
How The Auger Works
- Pellets in the Hopper: You load pellets into the hopper at the top of your stove.
- Motor Activation: When heat is needed, the control board sends power to the auger motor.
- Pellets Moved: The auger rotates, moving a set amount of pellets down a chute.
- Combustion: Pellets reach the burn pot, where they are ignited and burned to produce heat.
- Sensor Feedback: Sensors monitor the temperature and status, telling the control board if more pellets are needed.
If anything goes wrong in this process, the auger may stop feeding pellets, and the stove will lose heat.
Why Proper Auger Function Is Critical
A working auger means:
- Consistent heat output
- Safe stove operation
- Fuel efficiency
A faulty auger can lead to:
- Cold room temperatures
- Pellet backups or jams
- Damage to the stove
Many issues with the auger are preventable with regular maintenance and prompt troubleshooting.
Common Causes Of A Pelpro Auger Not Working
If your Pelpro auger has stopped, several things could be wrong. Each cause has its own signs and solutions. Here are the most common reasons:
- Pellet Jam or Blockage
- Faulty Auger Motor
- Control Board Problems
- Wiring or Connection Issues
- Bad Limit Switches or Sensors
- Fuse Problems
- Burned Out Auger Motor Capacitor
- Incorrect Settings or User Error
- Moisture in Pellets
- Obstruction in the Chute
- Damaged Auger Shaft or Flighting
- Blocked Air Intake or Poor Venting
- Auger Motor Overheating
- Stove Not Properly Cleaned
- Failed Safety Features
- Power Supply Fluctuations
- Software or Firmware Glitches
- Low-Quality or Wrong-Sized Pellets
Let’s look at each in detail.
1. Pellet Jam Or Blockage
Pellets can sometimes get stuck in the auger or chute. This is one of the most common issues. It usually happens if the pellets are damp, too long, or contain sawdust. Signs include a humming motor, but no pellet movement, or the auger stopping suddenly.
Tip: Always use high-quality, dry pellets. Check for pellet clumps or “bridging” in the hopper.
2. Faulty Auger Motor
The auger motor can fail after years of use or due to electrical surges. If the motor has burned out, you may hear a clicking sound, or the motor may feel hot. Sometimes, the motor runs but does not turn the auger because of internal damage.
Insight: Some motors fail intermittently before quitting completely. Test the motor with a multimeter or by direct connection.
3. Control Board Problems
The control board acts as the “brain” of your stove. If it malfunctions, it may not send power to the auger motor at the right time. Symptoms include no response when the stove is turned on, or random auger operation.
Non-obvious insight: Sometimes, the control board will work for other functions but not for the auger, due to a damaged relay.
4. Wiring Or Connection Issues
Loose or corroded wires can cut off power to the auger motor. Vibration during operation can slowly loosen connections. Signs include intermittent auger operation or sparks near connections.
Practical tip: Inspect wiring harnesses for wear and tightness. Look for discoloration as a sign of heat damage.
5. Bad Limit Switches Or Sensors
Stove safety depends on several limit switches and sensors. If they fail, the stove may “think” it’s unsafe to run the auger. This can happen if the stove overheats or if a sensor is faulty.
Example: A failed high-limit switch will prevent the auger from feeding more pellets.
6. Fuse Problems
A blown fuse in the control panel or auger circuit will prevent operation. Fuses blow due to surges, short circuits, or defective components. Always replace fuses with the correct type.
7. Burned Out Auger Motor Capacitor
Some auger motors use a capacitor to start and run smoothly. If the capacitor fails, the motor may hum but not turn. Capacitor failure is easy to miss for beginners.
Non-obvious insight: Swollen or leaking capacitors are a silent cause of auger problems.
8. Incorrect Settings Or User Error
It’s easy to overlook simple mistakes, such as setting the stove to “off” or “manual” mode when it should be “auto. ” Double-check the user settings and consult the manual for guidance.
9. Moisture In Pellets
If pellets have absorbed moisture, they can expand and jam the auger. They may also leave sticky residue, making jams more likely in the future.
Tip: Store pellets in a dry place, and never use damp or wet pellets.
10. Obstruction In The Chute
Foreign objects (such as screws or bits of plastic) can fall into the hopper and get stuck in the auger chute. This will quickly stop the auger from turning.
11. Damaged Auger Shaft Or Flighting
The auger shaft can bend, or the spiral (flighting) can break. This usually happens after years of use or if a hard object jams the auger. Check for visible damage during inspection.
12. Blocked Air Intake Or Poor Venting
Poor airflow can cause the stove to overheat, triggering safety sensors that stop the auger. Keep the air intake and vent pipes clear.
13. Auger Motor Overheating
Running the auger for long periods without rest can overheat the motor. Overheating may cause the motor to shut down until it cools.
14. Stove Not Properly Cleaned
Ash and dust build-up can affect sensors and moving parts. Regular cleaning is needed for smooth operation.
15. Failed Safety Features
Safety features like door switches will stop the auger if the stove door is open or not latched.
16. Power Supply Fluctuations
Voltage drops or surges in your home’s power can affect the auger motor and control board.
17. Software Or Firmware Glitches
Some modern Pelpro models use software to manage functions. Bugs or glitches can cause random failures.
18. Low-quality Or Wrong-sized Pellets
Poor quality or oversized pellets can jam or strain the auger.
