Traeger Pellet Grill Not Heating: Firepot and Igniter Fixes

Quick Answer

A Traeger not heating up is usually caused by a full firepot or a faulty igniter rod. Start by vacuuming out the firepot to ensure proper airflow, then verify the igniter glows orange during startup.

Most of the time when I roll up to a Traeger that won't heat, it's ash. Just a firepot so full of ash the igniter can't do its job and the air holes are completely blocked. Ignore it long enough and you'll burn out that igniter rod trying to light pellets in a clogged pot, and now you've got a $30 repair on top of nothing. Clean the firepot first, every single time.

Traeger Pellet Grill Not Heating: Firepot and Igniter Fixes

Here's the deal with Traegers not heating: the firepot fix costs nothing and solves it about 40% of the time. A new igniter rod is $20-35 and takes 20 minutes to swap. I replaced three of those last week. The two things people miss most are damp pellets sitting in the hopper all winter and cold weather temps, both of which kill your grill's performance even when everything else is working fine.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Firepot full of ash35%

Igniter rod burned out20%

Pellet supply issue (empty, jammed, damp)20%

Fan, probe, or airflow issue15%

Cold weather or wind10%

Symptoms You May Notice

You set the grill to 350F and it climbs to about 180F then just sits there and never goes higher no matter how long you wait
Temperature bouncing all over the place during a cook, swinging 50-100 degrees up and down randomly
No smoke coming out of the chimney during the first 5-10 minutes of startup when there should definitely be a solid plume
Open the lid after 10 minutes and the firepot is just full of loose unburned pellets sitting there cold, no fire, no char
LEr or Low Temp error flashing on the controller, which fires when the grill hasn't hit minimum operating temp within about 10 minutes of startup

Can you reset a Traeger pelletgrill to clear the NOT-HEATING code?

Unplug the grill completely and wait a full 30 seconds, not just 5. Plug it back in, then press and hold the power button to start a fresh startup cycle. You'll hear the auger turn and drop pellets into the firepot, then watch for the igniter to glow and pellets to catch. On WiFIRE models, if the app is still showing an error after restart, force-close it completely and reconnect fresh.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Did the fix not work?

If the problem comes back after following these steps, a component has permanently failed and needs replacement. Check the specific error code your pelletgrill is showing:

Frequently Asked Questions

My Traeger heats to 200F but won't go higher. Why?

This is almost always a restricted airflow situation. The fire's alive but barely, not strong enough to push the temp higher. First check the firepot for ash partially clogging the air holes, even a thin layer cuts airflow way down. Second, put your hand near the chimney and feel if there's decent airflow. If it's weak, the induction fan might be struggling. Third, check the chimney cap itself. I fixed one last month where grease buildup had the cap jammed halfway shut. Cleaned it in five minutes and the grill was hitting 450F no problem.

Traeger not heating up in cold weather - is that normal?

Totally normal, and way more of an issue than most people expect. Below 35F, that thin metal barrel loses heat faster than the firepot can make it. Traeger's insulation blanket is genuinely worth it, about $50-80 depending on your model. Without one, don't expect to hit much above 300-350F when it's really cold out. Also keep the hopper topped off in winter since cold weather burns through pellets faster, and stick to higher-quality hardwood pellets.

New Traeger not heating up out of the box. Defective?

Probably not. New Traegers need a burn-in cycle first: fire it up to 350F for about 30 minutes with nothing on the grates to cure the factory coating and season the barrel. Also double-check that the heat baffle is sitting correctly on its support brackets, these sometimes don't get installed right out of the box even if you follow the instructions carefully. If it still won't heat after a clean startup and burn-in, that's when you call Traeger support. They're pretty good about shipping replacement parts on new units.

Traeger not heating up after cleaning. What did I do wrong?

The heat baffle, almost every time. After cleaning, people set it back slightly crooked or resting on the edge of the firepot instead of flat on the support brackets. When the baffle's off even a little, hot air can't circulate right through the grill. Also check that the drip tray is sitting level above the baffle with the grease channel pointing toward the drip bucket. Sounds minor but the positioning of those two pieces really does affect how heat moves through the whole thing.

My igniter glows but the pellets still won't catch fire. What's going on?

That's a pellet quality or airflow problem, not the igniter. The igniter's doing its job, something else isn't cooperating. Grab a handful of pellets from the hopper and snap one in half. If it bends instead of snapping clean, your pellets have moisture in them, dump the hopper and get a fresh bag. If the pellets seem fine, check the induction fan, it has to be running strong to fan that ember into an actual flame. Also look at the air holes in the bottom of the firepot with a flashlight. Those need to be completely clear. A half-clogged firepot will let the igniter glow all day without ever getting a real fire going.
