Why Do Pellet Grills Explode? (Causes and Prevention)

A perfect day outdoors can be marred by a pellet grill explosion, turning your leisurely gathering into a chaotic event.

To keep your grilling experience safe and enjoyable, it’s crucial to understand what causes these explosions and implement proper safety precautions.

Why Do Pellet Grills Explode?

The main reasons behind pellet grill explosions:

Too many pellets in the firepot:

If there are too many pellets in the burn pot, usually more than an inch of pellets burning at once, or if they’re packed tightly, this can lead to an explosion.

Excess fuel makes it difficult for the grill to regulate its temperature, causing a buildup of heat.

Insufficient airflow:

A common cause of pellet grill explosions is when the burn pot becomes clogged with a mixture of ash and pellets.

This prevents air from flowing properly through the grill, causing the pellets to ignite too quickly.

The rapid ignition leads to a buildup of heat that has nowhere to escape, resulting in an explosion.

Incorrect shutdowns and power outages:

Pellet grills should always be shut down correctly to avoid explosions.

Most pellet grills have an automatic shutdown procedure when the power is turned off, but it’s important to consult the grill’s manual to ensure you don’t disrupt this cycle.

Sudden power outages or user mistakes can cause flameouts, leaving unburnt wood pellets in the firepot. When the grill is restarted, the excess fuel can trigger an explosion.

Top Tips for Safe Grilling: Avoiding Pellet Grill Explosions

Pellet grills are a favorite choice for many outdoor cooking aficionados. However, the possibility of explosions can be worrisome.

Thankfully, with a few straightforward precautions, you can prevent pellet grill explosions and savor both safe and scrumptious meals.

Here’s a list of essential tips to ensure your pellet grill sessions are safe and enjoyable:

1. Monitor pellet levels:

To avoid explosions, ensure there’s a sufficient amount of pellets in the burn pot but not an excess.

Always check for remaining pellets from prior cooking sessions before starting anew, as improper shutdowns and leftover pellets are the primary causes of explosions.

2. Invest in a backup generator:

If you reside in an area susceptible to power outages, consider using a backup generator to prevent pellet grill shutdowns.

When a power outage occurs, make sure the pellets in the burn pot burn out entirely and empty the hopper to avert explosions.

3. Open the lid when starting the grill:

Before igniting the grill, open the lid and leave it open for a minimum of 10 minutes to allow the flames in the burn pot to stabilize.

This step ensures proper airflow and helps control the flames.

4. Adhere to proper shutdown and maintenance procedures:

Consult the owner’s manual to familiarize yourself with the correct startup and shutdown processes for your pellet grill.

Regularly clean the fire pot and other grill components to prevent ash accumulation and maintain peak performance.

5. Keep a fire extinguisher close by:

It’s vital to have a fire extinguisher readily available in case of emergencies. Pellet grills can quickly ignite fires, making preparedness crucial.

6. Inspect the grill before use:

Before lighting the grill, examine the fire pot to confirm it’s empty. If anything unusual occurs, such as an unexpected shutdown, inspect the fire pot, hopper, and auger before attempting to restart.

Shutting Down Your Pellet Grill Safely

Correctly shutting down a pellet grill is essential for maintaining its safety and prolonging its lifespan.

While the specific steps might differ among manufacturers, the fundamental principles are consistent.

Follow this all-inclusive guide to safely shut down your pellet grill:

1. Remove cooked food:

After finishing your cooking session, take the food off the grill and store it in a suitable container or location.

2. Turn up the heat:

With the grill lid open, increase the heat to high and let it cook for an additional 5 to 10 minutes. This process burns off residual pellets in the burn pot and ensures it’s empty.

3. Begin the shutdown process:

Find the “cool down” or “shutdown cycle” setting on your pellet grill, and adjust the dial accordingly. If you’re unable to locate this setting, refer to your grill’s manual for guidance.

Certain models, such as Traeger grills, may feature an unmarked button that you’ll need to press and hold to start the shutdown cycle.

4. Exercise patience:

Allow the grill to complete its shutdown cycle, which typically lasts around 15 to 20 minutes (or up to 30 minutes for some grills).

Wait for the fan to stop running, signaling that the shutdown process is finished and it’s safe to continue.

5. Switch off and disconnect:

After the fan has stopped, turn the dial to the “off” position and unplug your grill.

6. Cool down and store:

Give the grill time to cool down completely before closing the lid and moving it to a secure storage spot.
