Traeger Not Heating Up? 7 Fixes That Actually Work

If your Traeger® grill is not heating up, the most common cause is a dirty fire pot filled with ash and unburned pellets. The fix is simple: power off the grill, vacuum out the fire pot, and restart. If that does not solve it, work through the diagnostic steps below to identify whether you have a bad igniter, auger jam, pellet quality issue, or electrical problem.

A Traeger that will not heat up is one of the most frustrating problems you can face, especially when you have guests coming or meat already seasoned and ready to go. The good news is that this problem almost always has a straightforward fix that you can handle at home without any special tools.

This guide walks you through every possible cause, from the simplest to the most involved, so you can get back to smoking as quickly as possible.

Before You Start: Safety First

Before working on your Traeger, always:

1. Power off the grill and unplug it from the outlet
2. Wait at least 10 minutes for all components to cool
3. Wear heat-resistant gloves if the grill was recently in use
4. Work in a well-ventilated area if cleaning out ash or old pellets

Fix 1: Clean Out the Fire Pot

This is the number one cause of a Traeger not heating up and the first thing you should check every time.

What happens: Ash and unburned pellet fragments accumulate in the fire pot, smothering the igniter and preventing proper airflow. The igniter glows but cannot ignite the pellets because there is too much debris in the way.

How to fix it:

1. Power off the grill and unplug it
2. Remove the grill grates, drip tray, and heat baffle to expose the fire pot
3. Use a shop vacuum to thoroughly clean out the fire pot — remove all ash, pellet dust, and debris
4. While you are in there, vacuum the entire bottom of the barrel
5. Inspect the fire pot for any warping or damage
6. Reassemble the grill and try starting it again

Pro tip: On Woodridge™ and Ironwood models with the EZ-Clean fire pot design, you can pull the lever to dump ash more easily. However, you should still do a full deep clean with a vacuum at least once every 3-5 cooks.

You will want a good set of Traeger drip tray liners and a quality grill brush for regular maintenance.

Fix 2: Check Your Pellet Quality

Bad pellets are the second most common reason a Traeger will not heat up properly.

What happens: Pellets absorb moisture from humidity, rain, or being stored in an open bag. Wet pellets swell, crumble, and will not ignite properly. They can also form a paste that clogs the auger and fire pot.

How to check:

1. Grab a handful of pellets from the hopper
2. Snap test: Good pellets snap cleanly in half. Bad pellets crumble or bend
3. Visual check: Look for sawdust at the bottom of the hopper — excessive dust means degraded pellets
4. Feel test: Pellets should feel smooth and hard, not soft or swollen

How to fix it:

1. If pellets fail any of these tests, empty the entire hopper
2. Vacuum out all pellet dust from the hopper
3. Fill with fresh, high-quality pellets like Traeger Signature Blend
4. Store unused pellets in a sealed container — never leave them in the hopper between cooks if you live in a humid climate

Model-specific note: The Pro 575, Pro 780, and older models without a hopper sensor will not alert you to low pellet levels. If your grill runs out of pellets mid-cook, you will need to follow the full shutdown and restart procedure rather than just adding more pellets.

Fix 3: Test the Igniter (Hot Rod)

The igniter, also called the hot rod, is the component at the bottom of the fire pot that glows red to ignite the pellets. Igniters are a wear item and typically last 1-3 years depending on usage.

How to test:

1. Remove the grill grates, drip tray, and heat baffle
2. Clean out the fire pot completely
3. Turn on the grill and set it to a Smoke or low temperature setting
4. Watch the fire pot for 2-4 minutes — you should see the igniter glow bright orange/red
5. If the igniter does not glow at all, it has failed and needs replacement

How to replace:

1. Igniters are held in place by a single bracket and one or two screws on the outside of the grill body
2. Disconnect the wiring harness and remove the old igniter
3. Install the new igniter, reconnect the wiring, and test

Replacement igniters are available directly from Traeger and typically cost $20-30. This is a 15-minute repair that requires only a Phillips screwdriver.

Fix 4: Check for an Auger Jam

The auger is the screw-shaped mechanism inside the auger tube that feeds pellets from the hopper to the fire pot. If it jams, no pellets reach the fire pot and the grill cannot heat.

Symptoms of an auger jam:

• You can hear the auger motor humming but the auger is not turning
• No pellets are dropping into the fire pot
• The hopper is full but the fire pot is empty after several minutes

How to fix it:

1. Power off and unplug the grill
2. Empty all pellets from the hopper
3. Use a shop vacuum to clear as much material as possible from the auger tube (vacuum from the hopper end)
4. If the jam is stubborn, you may need to remove the auger motor (usually 4 bolts) and pull the auger out to clear the blockage
5. Check for any foreign objects (pebbles, screws, hardened pellet paste)
6. Reassemble and test

Fix 5: Check Your Electrical Connection and GFI/GFCI Outlet

A tripped GFI (Ground Fault Interrupter) outlet is a surprisingly common cause of a Traeger not heating up — and one that is easy to overlook.

What happens: GFI outlets are designed to trip when they detect a ground fault. Traeger grills can trip GFI outlets, especially during ignition when the hot rod draws the most current, or in wet or humid conditions.

How to fix it:

1. Check the outlet your Traeger is plugged into — if it has "Test" and "Reset" buttons, it is a GFI outlet
2. Press the Reset button firmly
3. If it trips again immediately, try a different outlet (preferably a non-GFI outlet on a dedicated circuit)
4. Make sure the power cord and plug are dry — moisture on the connections can cause GFI trips
5. Check the power cord for any damage, fraying, or exposed wires

Important: Traeger recommends using a dedicated 15-amp circuit for their grills. Sharing a circuit with other high-draw appliances can cause problems. Extension cords are not recommended, but if you must use one, it should be a heavy-duty outdoor-rated cord (12-gauge or heavier) and as short as possible.

Fix 6: Inspect the Controller

The controller is the brain of your Traeger. If it fails, the grill may power on but not properly manage the ignition cycle.

Signs of a controller problem:

• The display is blank or flickering
• Error codes appear on the screen (see our Traeger error codes guide for details)
• The grill powers on but the fan and auger do not activate
• Temperature readings are wildly inaccurate

What to try:

1. Power cycle the grill (unplug for 30 seconds, then plug back in)
2. On WiFIRE-enabled models (Woodridge™, Ironwood, newer Pro Series), check for firmware updates through the Traeger app
3. Inspect the wiring connections on the back of the controller — look for loose or corroded connectors
4. If the controller display works but the grill does not heat, the controller may need replacement

Fix 7: Check the Induction Fan

The induction fan feeds oxygen to the fire pot to keep the fire burning. If it fails, pellets may ignite but the fire will quickly die.

How to check:

1. Start the grill and listen — you should hear the fan running (a low humming/whirring sound)
2. Look for smoke movement — if the fan is working, smoke should be moving upward and out of the chimney
3. If the fan is not running, check its wiring connection to the controller
4. A failed fan motor will need to be replaced

Prevention Tips

The best way to avoid your Traeger not heating up is regular maintenance:

• After every cook: Burn off residue by running the grill at high temp for 10 minutes, then brush the grates with a grill brush
• Every 3-5 cooks: Vacuum out the fire pot, clean the drip tray, and replace drip tray liners
• Every 20 cooks or once per season: Deep clean the entire grill including the chimney, auger area, and all interior surfaces
• Always: Store pellets in a dry, sealed container and use a quality grill cover to protect against moisture
• Use quality pellets: Cheap, off-brand pellets with high bark content produce more ash and can clog the fire pot faster. Traeger Signature Blend pellets are a reliable choice

Frequently Asked Questions

Why does my Traeger take so long to heat up?

A Traeger typically takes 10-15 minutes to reach cooking temperature. If it is taking significantly longer, the most common causes are a dirty fire pot, low-quality pellets, or cold ambient temperatures. In freezing weather, allow an extra 5-10 minutes and consider using a Traeger insulation blanket. Also make sure the lid is fully closed during preheat — opening the lid releases heat and extends preheat time considerably.

Can a Traeger igniter work intermittently?

Yes. A failing igniter can work some of the time and fail other times. If you notice your grill sometimes starts fine and other times produces a lot of smoke without igniting (which can lead to a flashback), the igniter is likely on its way out. Replace it proactively — igniters are inexpensive and easy to swap.

Why did my Traeger stop heating in the middle of a cook?

Mid-cook flameouts are usually caused by running out of pellets, a pellet jam in the auger, or excessive ash buildup in the fire pot. Check the hopper level first. If there are pellets in the hopper but none in the fire pot, you likely have an auger issue. Also check for temperature swings which can indicate other underlying problems.

Should I manually light my Traeger if the igniter fails?

Traeger does not recommend manually lighting the grill with a match or lighter, and doing so can be dangerous if pellets have been accumulating in the fire pot. If your igniter fails, replace it. As a temporary workaround, some experienced users place a small fire starter in the fire pot, but this should only be done with extreme caution and with the grill lid fully open.

How often should I replace my Traeger igniter?

Most Traeger igniters last 1-3 years with regular use. If you grill 2-3 times per week, expect to replace the igniter every 1-2 years. If you notice longer ignition times, the igniter glowing less brightly, or intermittent failures to ignite, it is time for a replacement.
