There can be several reasons that a pellet grill can catch on fire and here I will explain the most common ones.

Many people are thinking that cooking on a pellet grill is maintenance free but it is clear that this is not the case.

Although a pellet grill is easy to use as you can read in the many pellet grill reviews I did they still can catch on fire just as any other grill.

If you like to see stats on grill fires you can find them here https://www.nfpa.org/-/media/Files/News-and-Research/Fire-statistics-and-reports/US-Fire-Problem/Fire-causes/osGrills.pdf.

There are no separate stats for the types of grill used and I understand that.

Pellet Grill Components And Fire Hazards

It is not one component in a pellet grill that is the single cause of a pellet grill fire. It is the combination of two or a few of them that can cause the fire.

“Heat and grease are the most common factors in grill fires and pellet grills are no exception to that rule.”

What Can Cause A Pellet Grill fire?

Here are the causes and combinations in a pellet grill that can cause a fire.

Grease built up

Built-up grease is one of the most mentioned causes of any grill fire.

Electrical fire

we all know that you need electricity to run a pellet grill and although a low risk there is a change in an electric fire in the control box.

Auger Keeps moving

The pellets are fed in the fire pot through the rotation of the auger and if the auger keeps moving too fast or too long there can be too many pellets in the fire pot to start a fire.

Auger not moving

If the auger stops moving while there is a fire in the firepot the fire can get into the auger and slowly move to the hopper where all the pellets are stored.

How To Prevent A Pellet Grill Fire

We all know the saying that an ounce of prevention is better than a pound of cure and in the case of a pellet grill fire that is actually easy to do.

Maintain The Moving Parts

As described above the auger needs to be able to move the pellets from the hopper to the fire pot.

Keeping the auger free from any obstruction is not too hard to do. Make sure your pellets can’t get wet. I have seen pictures that they change almost in concrete when they get wet and dry out.

Do Not Use Your Pellet Grill In The Rain.

Water and electricity are born enemies and do not go hand in hand.

So, keeping your pellet grill out of the rain is the best tip for that. Although some manuals mention it should be possible I think it is better not to take any risks.

If you can keep it under a porch or in the open door of your garage.

A more general tip is to use the correct extension cord for your model pellet grill.
