Your Traeger grill suddenly stops feeding pellets during a brisket cook. The temperature plummets, smoke vanishes, and frustration sets in—this is the classic sign of a jammed auger. When wood pellets sit stagnant in your Traeger’s auger tube, they absorb moisture from humid air, swelling into a dense, concrete-like mass that blocks pellet flow. Left unaddressed, this causes temperature spikes, failed ignitions, or even dangerous “burn back” scenarios where fire travels into the hopper. Learning how to empty Traeger auger components properly isn’t just maintenance—it’s essential for reliable cooking and preventing costly repairs. In this guide, you’ll discover the exact steps to clear jams safely, avoid common pitfalls, and keep your grill running like new.
Ignoring auger maintenance risks more than ruined meals. Moisture-compromised pellets create compacted obstructions that strain the motor, trigger error codes like “AUG” or “ERR,” and force your grill into emergency shutdowns. The good news? Most jams are preventable with routine clearing. Whether you own a Pro 575, Ironwood, or Timberline series, this process takes under 20 minutes and requires only basic tools. By the end, you’ll know how to empty your Traeger auger correctly after every cook, during seasonal storage, or when troubleshooting feeding failures—ensuring consistent smoke and heat for flawless results.
Why Pellet Moisture Causes Traeger Auger Jams
Stagnant pellets transform into auger-killing hazards within hours. Wood pellets are hygroscopic, meaning they actively pull moisture from humid air. As pellets absorb humidity inside the auger tube, wood fibers swell and soften, binding together into a paste that hardens like cement. This compacted mass blocks pellet flow, causing three critical failures:
- Temperature collapse when the fire pot starves for fuel during long cooks
- “No fire” errors as pellets fail to reach the ignition rod
- Motor burnout from the auger struggling against immovable obstructions
Modern Traeger controllers combat this with a built-in “Clear Auger” function specifically designed to purge moisture-compromised pellets before jams solidify. Skipping this step—even for 48 hours of storage—invites disaster. User reports confirm that 90% of springtime grill failures trace back to pellets left in the auger tube over winter, where humidity turns them into an impenetrable barrier.
Essential Safety Steps Before Clearing Your Auger
Never skip these precautions: Unplug your Traeger and confirm all components are cool to the touch. An active auger motor or residual heat from the fire pot creates fire and electrical hazards. While waiting for the grill to cool, gather these tools:
- Shop vacuum (dedicated for ash/pellet dust—never use a household vacuum)
- Flexible non-metallic rod like a zip tie or plastic cleaning brush (metal tools scratch the auger tube)
- Small flashlight to inspect dark areas
- Dust mask and safety glasses (pellet fines irritate lungs and eyes)
- Phillips screwdriver for motor cover removal
Critical warning: If you smell smoke or see ash in the hopper, stop immediately. This indicates “burn back”—fire traveling into the auger—and requires full disassembly. Do not proceed until the grill is completely cold and unplugged.
Step-by-Step: Clearing Your Traeger Auger Tube
Run the “Clear Auger” Function on Modern Grills (Pro/Ironwood/Timberline)
This is the fastest, safest method for 90% of clearing needs. The controller runs the auger in reverse, expelling pellets back into the hopper:
1. Plug in the grill and power on the controller
2. Navigate to Settings > Maintenance > Clear Auger (exact path varies by model)
3. Confirm the cycle—do not open the hopper lid during operation
4. Listen for the motor reversing; pellets will visibly eject into the hopper in 60-90 seconds
5. Unplug the grill once complete and vacuum residual dust from the hopper
Pro tip: Run this cycle before storing pellets long-term or switching pellet brands. It prevents moisture absorption during idle periods.
Manually Clear Jams in Older Traeger Models (Without “Clear Auger” Function)
For pre-2018 grills lacking automated clearing:
1. Unplug the grill and remove all visible pellets from the hopper with a scoop
2. Attach your shop vacuum hose to the hopper opening and seal gaps with a towel
3. Turn on the vacuum while gently feeding a flexible zip tie into the auger tube
4. Rotate the zip tie clockwise to break up compacted pellets—never force it
5. If resistance is firm, stop and proceed to deep cleaning (below)
Critical mistake to avoid: Never use screwdrivers or metal rods. They gouge the auger tube lining, creating ridges where future jams anchor.
Final Vacuum Check After Clearing
After any clearing method:
– Vacuum the hopper interior thoroughly, especially corners where “fines” (pellet dust) accumulate
– Shine a flashlight into the auger tube inlet—no visible pellets should remain
– Wipe the hopper grate with a dry cloth to eliminate moisture traps
If pellets reappear after vacuuming, repeat the “Clear Auger” cycle. Residual pellets indicate incomplete clearing.
Deep Cleaning Your Traeger Auger Tube (For Stubborn Jams)
When the “Clear Auger” cycle fails, disassembly is required. Perform this every 20 cooking hours or when pellets jam repeatedly:
- Unplug and cool the grill completely
- Remove the hopper cover and clear all pellets
- Locate the motor cover (rear/side of hopper) and remove its 3-4 screws
- Disconnect the motor wiring harness—note wire positions for reassembly
- Loosen the motor mount bolts while holding the auger shaft to control spring tension
- Slide the auger flighting (spiral screw) straight out of the tube
- Scrub the tube interior with a bottle brush and vacuum debris
- Inspect the auger for rust, warping, or broken flighting sections
Warning: Forcing the auger during removal can shear the plastic coupler—a designed failure point protecting your motor. If the coupler snaps, replace it (Traeger part # TGC-0003).
Diagnosing Traeger Auger Failures in 3 Steps
When your grill won’t feed pellets, diagnose systematically:
Step 1: Check for Pellet Quality and Moisture
- Symptom: Pellets crumble into sawdust when handled
- Fix: Switch to low-fines hardwood pellets (like Traeger Signature or Cookshack) and store in airtight containers
Step 2: Test the Auger Motor Independently
- Symptom: No motor sound during startup
- Test: Unplug the grill, then apply 12V DC directly to motor terminals with alligator clips
- Result: If it spins, the controller is faulty; if silent, replace the motor
Step 3: Inspect the Shear Pin/Coupler
- Symptom: Motor runs but pellets don’t move
- Check: Locate the plastic coupler between motor and auger shaft—it often shears when jammed
- Fix: Replace the coupler ($8 part) without motor disassembly
Urgent red flag: Smoke from the hopper indicates “burn back.” Discontinue use immediately and deep-clean the entire auger system.
Prevent Traeger Auger Jams With These Proven Habits
Store Pellets Correctly—Every Time
- Keep pellets in sealed 5-gallon buckets with oxygen absorbers (not the bag!)
- Never leave pellets in the hopper over 48 hours—even in dry climates, humidity penetrates within 24 hours
Schedule Maintenance Around Cooking Cycles
- After every 12+ hour cook: Run “Clear Auger” cycle and vacuum hopper
- Before winter storage: Empty hopper and run clearing cycle—pellets left in tubes guarantee spring jams
- Every 20 cooking hours: Deep-clean the auger tube (ignoring this causes 70% of motor failures)
Upgrade Your Pellet Quality
Low-cost pellets contain 20-30% “fines” (sawdust) that absorb moisture instantly. Users report 90% fewer jams after switching to premium hardwood pellets with <5% fines. Check for pellet dust by shaking a handful—if sawdust falls through your fingers, discard the bag.
Emptying your Traeger auger isn’t optional—it’s the frontline defense against cooking disasters. By running the “Clear Auger” cycle after every major cook, storing pellets properly, and deep-cleaning every 20 hours, you’ll avoid 95% of common jams. Remember: moisture is the silent killer of pellet grills, and stagnant pellets are jamming time bombs. Treat your auger like the precision component it is, and your Traeger will deliver championship results for years. For model-specific clearing instructions, always consult your owner’s manual—then fire up with confidence knowing your auger runs clean.
