Traeger Grill Problems: 12 Common Issues and How to Fix Them

Traeger® pellet grills are among the most reliable on the market, but they are not maintenance-free machines. Every pellet grill — regardless of brand — has moving parts, electronics, and combustion components that require attention over time. The good news is that the vast majority of Traeger® problems have straightforward fixes you can handle at home.

This guide covers the 12 most common Traeger® grill problems we see, explains what causes each one, and gives you quick-fix solutions. For the most frequently reported issues, we have written detailed step-by-step troubleshooting guides that go much deeper — those are linked throughout.

Important safety note: Before working on any internal component of your Traeger® grill, always power off the grill, unplug it from the outlet, and wait at least 10 minutes for components to cool.

1. Traeger Not Heating Up

Symptoms: Grill powers on, auger feeds pellets, but the grill does not reach temperature or takes far longer than the usual 10-15 minutes.

Most likely cause: A dirty fire pot filled with ash and unburned pellet debris. The igniter cannot make proper contact with fresh pellets when the fire pot is full of ash.

Quick fix: Power off, remove grill grates and drip tray, and vacuum out the fire pot thoroughly. Replace pellets if they are old or damp. Restart the grill.

Other possible causes: A failed igniter, a tripped GFI outlet, low-quality or wet pellets, or an auger that is not feeding pellets into the fire pot.

This is the most common Traeger® problem by a wide margin. We have a complete diagnostic walkthrough in our Traeger not heating up guide that covers all seven possible causes with step-by-step fixes.

2. Temperature Swings

Symptoms: The grill temperature fluctuates more than 25°F above or below the set temperature, causing inconsistent cooking results.

Most likely cause: Ash buildup in the fire pot affecting combustion consistency, low-quality pellets with inconsistent density, or cooking in windy conditions without proper positioning.

Quick fix: Clean the fire pot, switch to high-quality pellets like Traeger® Signature Blend, and position the grill out of direct wind. On Woodridge™ and Ironwood models, make sure you are running the latest firmware through the Traeger app, as firmware updates often improve temperature control algorithms.

Other possible causes: A malfunctioning RTD temperature probe, a damaged heat baffle, or the grill lid not sealing properly.

For a complete diagnostic including how to test the RTD probe and recalibrate temperature, read our Traeger temperature swings guide.

3. WiFi Connection Issues

Symptoms: The grill will not connect to your home WiFi network, repeatedly drops connection, or shows as offline in the Traeger app despite being powered on and within range.

Most likely cause: The grill is too far from the router, there is interference from other devices, or the grill is attempting to connect to a 5GHz network (Traeger® grills only support 2.4GHz WiFi).

Quick fix: Confirm your router broadcasts a 2.4GHz network and that you are connecting the grill to that specific band. Move the grill within 30 feet of the router for initial setup. Power cycle the grill by unplugging it for 30 seconds and plugging it back in.

Other possible causes: Router firmware needs updating, the grill's WiFi module needs a factory reset, or the Traeger app needs to be reinstalled.

WiFi issues are the second most reported Traeger® complaint. Our Traeger WiFi troubleshooting guide walks through every fix from basic to advanced, including how to factory reset the WiFi module.

4. Error Codes on the Controller

Symptoms: The controller displays an error code such as LEr, HEr, ER1, ER2, or a flashing temperature reading.

Most likely cause: Each error code points to a specific problem. LEr means Low Error Reading (the grill detected a temperature too low, usually a flameout). HEr means High Error Reading (the grill detected an unsafe temperature, usually a grease fire or runaway temperature).

Quick fix: For LEr, the grill has flamed out — turn it off, clean the fire pot, check pellet quality, and restart. For HEr, turn the grill off immediately, open the lid carefully, and let the grill cool completely. Check for grease buildup on the drip tray and heat baffle.

We have a comprehensive Traeger error code reference that covers every error code, what triggers it, and the specific fix for each one.

5. Auger Not Turning

Symptoms: The auger motor is not spinning, pellets are not feeding from the hopper to the fire pot, or you hear the motor humming but the auger is not moving.

Most likely cause: A pellet jam in the auger tube, usually caused by moisture-swollen pellets that expanded and locked the auger in place. Less commonly, the auger motor has burned out.

Quick fix: Turn off the grill and unplug it. Empty the hopper of all pellets. Using a long wooden dowel or the handle of a wooden spoon, try to free the jammed pellets from the top of the auger tube. If the jam is severe, you may need to remove the auger motor to access the tube from below.

Prevention: Always empty the hopper after cooking if you live in a humid climate. Use fresh, high-quality pellets and store unused pellets in a sealed container.

Our detailed Traeger auger troubleshooting guide covers motor testing, full auger removal, and how to prevent future jams.

6. Grill Not Igniting

Symptoms: The grill goes through the startup cycle but pellets do not ignite. You see pellets accumulating in the fire pot without catching fire, or the grill produces heavy white smoke during startup but never transitions to clean combustion.

Most likely cause: A worn-out or failed igniter. Traeger® igniters are hot rods that glow red to ignite pellets. Over time (typically 1-3 years of regular use), they degrade and stop reaching ignition temperature.

How to diagnose:

1. Power off the grill and remove the grates, drip tray, and heat baffle
2. Look directly at the igniter in the fire pot
3. Power the grill on and start a normal cycle
4. Watch the igniter — it should glow bright red/orange within 2-3 minutes
5. If it does not glow at all, or glows weakly, the igniter needs replacement

How to fix: Replacement igniters are available directly from Traeger® and cost $15-$25. The swap takes about 15-20 minutes with basic tools (a socket wrench and screwdriver). Traeger's support site has model-specific replacement instructions.

Important: If pellets have been accumulating in the fire pot without igniting, vacuum out ALL unburned pellets before attempting to restart. A fire pot full of unignited pellets can cause a dangerous flashback when they finally catch fire.

7. Excessive Smoke or White Smoke

Symptoms: The grill produces thick, billowing white smoke that does not clear up after the first 5-10 minutes of startup, or the grill produces more visible smoke than usual during cooking.

Most likely cause: During the first 5-10 minutes of every cook, white smoke is completely normal — this is the startup phase where pellets are igniting and combustion is stabilizing. If heavy white smoke persists beyond 10 minutes, the likely culprit is wet or degraded pellets that are not combusting cleanly.

Quick fix:

• Wait at least 10 minutes — startup smoke is normal and will transition to thin, barely-visible "blue smoke" once combustion stabilizes
• If smoke persists, check pellet quality (the snap test: good pellets break cleanly, bad pellets crumble)
• Clean the fire pot — excess ash prevents clean combustion
• Make sure the fire pot holes are clear and not clogged with debris

When to be concerned: If the grill is producing thick smoke AND the temperature is not rising, you may have a smoldering fire rather than active combustion. Shut the grill down, clean the fire pot, replace pellets, and restart.

8. Grease Fire

Symptoms: Flames visible inside the barrel beyond the fire pot area, temperature reading spikes dramatically (triggering a HEr error code), or visible fire coming from around the drip tray.

Most likely cause: Grease and drippings have accumulated on the drip tray, heat baffle, or barrel floor and ignited. This is almost always a maintenance issue — regular cleaning prevents grease fires entirely.

How to handle a grease fire:

1. Turn the grill off using the power button
2. Do NOT open the lid — oxygen feeds fire. Let the fire starve with the lid closed
3. If the fire does not subside within a few minutes, disconnect power and carefully smother with baking soda (never use water on a grease fire)
4. Once the grill is cool, thoroughly clean the drip tray, heat baffle, and barrel floor

Prevention: This problem is 100% preventable with regular cleaning. Use Traeger® drip tray liners and replace them every 2-3 cooks. Clean the drip tray and heat baffle at least once every 5 cooks, or after every high-fat cook (brisket, pork shoulder, chicken thighs). Our how to clean your Traeger grill guide covers the full cleaning process.

9. Pellets Not Feeding

Symptoms: The hopper has pellets, but they are not moving down into the auger tube. The fire pot runs dry and the grill flames out. Sometimes you can see a "tunnel" or "bridge" forming in the hopper where pellets near the walls are stuck while the center empties.

Most likely cause: Pellet bridging. This happens when pellets form an arch over the auger inlet, supporting themselves against the hopper walls instead of falling into the auger. It is more common with very smooth pellets, in humid conditions, or when the hopper is less than half full.

Quick fix:

1. Open the hopper lid and push down on the pellets with your hand or a wooden spoon to break the bridge
2. Shake the hopper gently if accessible
3. Top off the hopper — a full hopper has more weight pressing pellets downward, which reduces bridging

Prevention: Do not let the hopper run below one-quarter full during long cooks. On models with a pellet sensor (Woodridge™ Pro and above), set alerts for low pellet levels. Store pellets in a dry environment to prevent moisture-related swelling that makes bridging worse.

10. Uneven Cooking

Symptoms: Food on one side of the grill cooks faster than the other side. One end of a rack of ribs is done 30 minutes before the other end. Pizza crust is charred on the left but pale on the right.

Most likely cause: All pellet grills have some degree of hot spots due to the fire pot being on one side and heat needing to travel across the barrel. However, significant unevenness usually indicates a problem with the heat baffle or drip tray.

Quick fix:

1. Remove the grill grates and check that the heat baffle is properly seated and not warped
2. Clean any grease or debris from the heat baffle — buildup can create uneven heat distribution
3. Ensure the drip tray is sitting flat and angled correctly toward the grease drain
4. If you have a multi-probe thermometer, place probes on each side of the grill to map the actual temperature variance

Workaround: If mild unevenness persists (which is normal), rotate your food 180 degrees halfway through the cook. Place items that need more heat closer to the fire pot side, and items that need gentler heat on the opposite side.

On Ironwood and Timberline models: These series feature downdraft exhaust and enhanced heat distribution that significantly reduces hot spots compared to the Woodridge™ and Pro series. If even cooking is critical to you (pizza, baking, multiple racks of ribs), the Ironwood is worth considering.

11. Rusted Grill Grates

Symptoms: Visible rust on grill grates, rust flakes transferring to food, or grates becoming rough and sticky.

Most likely cause: Porcelain-enameled grill grates (standard on Pro and Woodridge™ series) will eventually chip with normal use. Once the porcelain coating chips, the exposed steel underneath is vulnerable to rust, especially in humid environments or when the grill is left uncovered.

How to fix:

1. Remove the grates and scrub with a stiff grill brush to remove loose rust
2. Wash with warm soapy water and dry thoroughly
3. Coat the grates with a thin layer of high-heat cooking oil (canola or vegetable oil)
4. Run the grill at 350°F for 30 minutes to bake the oil coating on

Prevention:

• Use a grill cover whenever the grill is not in use — moisture is the primary cause of rust
• Oil grates lightly after each cook while they are still warm
• Avoid using metal utensils that can chip the porcelain coating
• Follow a regular maintenance schedule

When to replace: If rust has eaten through the grates to the point where they are structurally weakened or producing significant flaking, replacement grates are available from Traeger® for $40-$80 per set depending on model.

12. App Not Connecting to Grill

Symptoms: The Traeger app shows the grill as offline even though the grill is powered on and connected to WiFi, or the app cannot find the grill during initial setup.

Most likely cause: The app and grill may be on different networks, the app needs updating, or the Traeger cloud service is experiencing an outage.

Quick fix:

1. Check grill WiFi status — On the controller, verify the WiFi icon is solid (not blinking). A blinking icon means the grill is not connected to your network
2. Force close and reopen the app — This resolves the majority of app connectivity issues
3. Confirm same network — Your phone and grill must be on the same 2.4GHz WiFi network
4. Check for app updates — Outdated app versions can lose compatibility with grill firmware
5. Power cycle the grill — Unplug for 30 seconds, plug back in, and wait 2-3 minutes for the WiFi module to reconnect

If the grill connects to WiFi but the app still shows offline: This usually indicates a Traeger cloud service issue. Check Traeger's social media channels or status page for reported outages. In the meantime, you can still control the grill manually using the controller on the grill itself.

Preventive Maintenance: Avoid Most Problems

The reality is that 8 of these 12 problems are directly caused by insufficient maintenance. A consistent cleaning and maintenance routine eliminates the vast majority of Traeger® issues before they start.

After every cook:

• Scrape grill grates with a brush while warm
• Check and empty the grease bucket

Every 3-5 cooks:

• Vacuum out the fire pot
• Replace or check drip tray liners
• Wipe down the drip tray and heat baffle

Every 20-25 cooks or once per season:

• Deep clean the entire barrel interior
• Inspect the igniter, auger, and fan
• Check all hardware for looseness
• Inspect the gasket seal on the lid
• Oil the grill grates

Our full Traeger maintenance schedule guide breaks down exactly what to do and when, with a printable checklist.
