Green Mountain Grill Auger Not Turning (8 Quick Fixes That Work Every Time)

Green Mountain Grills (GMG) are a popular choice among BBQ enthusiasts for their convenience and wood-fired flavor. However, like any grill, they can experience technical difficulties.

One common issue users may encounter is the auger not turning. This problem can prevent the grill from feeding pellets into the firebox, disrupting your cooking process.

In this blog post I will be sharing some of the causes of Green Mountain Grill Auger not turning and how to fix it.

Let’s get started, shall we?


What Causes Green Mountain Grill Auger Not Turning?

#1. Pellet Jam

One of the most frequent causes of an auger not turning in a Green Mountain Grill is a pellet jam. The auger is responsible for moving pellets from the hopper into the firebox where they can be ignited.

If pellets become stuck or jammed in the auger tube, this can prevent the auger from turning. Pellet jams can occur if the grill is left outside in the weather, causing the pellets to swell and stick together.


#2. Auger Motor Issues

Another potential cause is a problem with the auger motor itself. If the motor is faulty or has burned out, it will not be able to turn the auger. This could be due to a manufacturing defect or wear and tear over time. If you suspect the motor is the issue, it may be necessary to replace it.


#3. Power Supply Problems

The auger motor requires electricity to operate. If there is an issue with the grill’s power supply, this could prevent the auger from turning.

This could be due to a tripped breaker, a blown fuse, or a problem with the power outlet.


#4. Control Board Malfunctions

The control board is the brain of the grill, regulating power to the auger motor and other components. If there is a malfunction with the control board, it may not send the correct signals to the auger motor, leading to operational issues.


#5. Mechanical Failures

Occasionally, the auger itself might be physically obstructed by debris or damage to the auger blade. This can occur if foreign objects find their way into the hopper or if the auger has been damaged through misuse or an accident.


#6. Ash Buildup

Over time, ash can accumulate in the firebox and around the auger mechanism. This buildup can obstruct the movement of the auger, preventing it from turning efficiently. 


#7. Incorrect Assembly or Wear and Tear

If the grill has been recently assembled or disassembled for cleaning, it’s possible that the auger was not reassembled correctly.

This could lead to misalignment, which might hinder the auger’s movement. Additionally, over time, the components of the auger system can wear down, leading to reduced performance or failure.


#8. Temperature Swings

Extreme temperature swings can also affect the operation of your pellet grill. If the grill has been exposed to very cold temperatures, the grease or other components may have thickened or solidified, making it difficult for the auger to turn.

Conversely, very high temperatures can cause expansion of metal parts, potentially leading to jams or mechanical issues.


#9. Firmware Glitches

Sometimes, the firmware that controls the grill’s operations can have glitches or require updates. If the firmware is not functioning correctly, it might not be sending the right commands to the auger motor.


#10. Sensor Malfunctions

Green Mountain Grills are equipped with various sensors that monitor the grill’s performance. If a sensor is malfunctioning, it could incorrectly report that there is a problem, causing the control board to stop the auger from turning as a safety precaution.


Green Mountain Grill Auger Not Turning (7 Quick Fixes That Work Every Time)

#1. Tap the Auger Tube

Sometimes, a simple solution is all it takes. If your auger is stuck, the pellets inside the tube might be creating a blockage. Gently tapping the auger tube can dislodge the pellets and get things moving again.

Be cautious not to hit too hard, as you don’t want to damage the grill.

This method is a quick and easy first step to alleviate an auger jam, as demonstrated in this helpful video by Green Mountain Grills.


#2. Cycle the Grill

Turning the grill into cycle “0” (the first stage of the normal start-up procedure) and simultaneously tapping the auger tube with a mallet or small hammer can also help.

This process can jog the auger loose and is recommended by Green Mountain Grills for the Jim Bowie model.


#3. Clear the Firebox

If the auger isn’t turning, the pellets may be jammed around the auger’s intake. Turn off the grill, and carefully move the pellets around in the firebox.

After adjusting the pellets, try turning on the grill again to see if the auger begins to move. This solution is suggested for general Green Mountain Grill troubleshooting.


#4. Dismantle and Clean

If tapping and cycling do not work, you might need to dismantle the auger to clear a severe jam. This involves unwinding and removing the auger to get rid of the pellet mass causing the jam.

While this is more time-consuming, it can be a necessary step to get your grill working properly again.


#5. Check the Motor and Connections

Sometimes, the issue may not be with the auger itself but with the motor or electrical connections that power it. Ensure that the motor is getting power by checking the connections.

Loose or corroded wires can prevent the motor from functioning. If the motor is not making any noise when you try to start the grill, this could indicate an electrical issue.

Make sure all connections are secure and clean any corrosion with a wire brush or contact cleaner.


#6. Inspect the Auger Motor

If the connections are fine, but the auger still won’t turn, the motor might be the problem. Listen for a humming sound from the motor; if it’s silent, the motor may need to be replaced.

You can find replacement motors on the Green Mountain Grills website or from authorized dealers. When replacing the motor, always make sure to follow the manufacturer’s instructions or consult with a professional if you’re unsure.


#7. Reset the Grill’s Controller

A less common but possible cause for an auger not turning is a glitch in the grill’s control system. A simple reset can sometimes clear these issues.

To reset the controller, turn off the grill and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on.

This can sometimes reboot the system and resolve any software-related issues that may be affecting the auger’s operation.


#8. Contact Support

If none of the above fixes work, it may be time to reach out to Green Mountain Grills’ customer support. They can offer troubleshooting advice specific to your model and situation. It’s possible that your grill may still be under warranty, and if a part needs to be replaced, they can guide you through the process or send a technician to help.


Preventive Measures

To prevent future auger jams, it’s essential to follow a few maintenance tips:

  • Use high-quality pellets that are less likely to cause jams due to their uniform size and low dust content.
  • Store your pellets in a dry place to prevent them from swelling and getting stuck in the auger.
  • Clean your grill regularly, including the auger tube, to ensure there’s no buildup of pellet dust and debris.
  • Schedule Regular Maintenance
  • Upgrade Firmware


An auger that won’t turn can be frustrating, but with these quick fixes, you can often solve the problem yourself and get back to grilling.

The key to smooth operation is regular maintenance, proper storage of pellets, and being proactive about any signs of trouble.

If you’ve tried all the solutions and your Green Mountain Grill auger is still not turning, don’t hesitate to contact professional support for further assistance.
