Your grill hits ignite, the fan spins up, and then... nothing feeds. Or worse, the display flashes "Auger Overcurrent" mid-cook and the whole thing shuts down while your brisket sits at 140°F. Before you assume the worst, here's the number that matters: the large majority of auger complaints on both Traeger and Pit Boss grills trace back to a jam, not a dead motor.

That distinction is the whole point of this guide. An auger motor is a $30-$50 part and a 20-minute swap once you're sure it's actually the problem. But most people who buy a replacement motor never needed one — they had wet pellets, a stray wood chip, or a sheared pin, and the motor was fine all along.

This guide walks through both platforms side by side: how the auger system works, the sound-based diagnostic that tells you what's wrong in under a minute, the Traeger-specific Auger Overcurrent flow, the Pit Boss shear-pin design that's easy to miss, and the point where replacing the motor is genuinely the right call. It also flags the codes that get mistaken for auger failures but aren't.

Quick Reference: Symptom → Likely Cause → Fix

How the Auger System Actually Works

Every pellet grill uses the same basic mechanism: a corkscrew-shaped metal shaft (the auger) sits inside a tube running from the hopper down to the firepot. An electric motor with a reduction gearbox turns that shaft slowly — roughly 2 RPM on most consumer grills — walking pellets forward a few at a time. When the controller calls for fuel, the motor engages; when it doesn't, the motor sits idle.

Traeger's WiFIRE-enabled (D2) grills use a 24V DC motor that can run forward, reverse, and at variable speed — which is what makes the Clear Auger function possible. Older non-WiFIRE Traeger models use a simpler AC motor with a small fan on the back that spins visibly when the motor is engaged, which doubles as a free diagnostic: if that fan isn't turning, the motor isn't getting power.

Pit Boss uses a broadly similar AC motor on most models (a 12V DC motor on Pro Series Elite units), but with one important design difference: a shear pin connects the motor shaft to the auger itself. That pin is a deliberate weak point — it's meant to snap before the gearbox does when something jams. It also means "motor spins, auger doesn't" is a distinct and very common Pit Boss failure mode that barely exists on Traeger.

Keep those two architectures in mind, because they lead to different first moves when something goes wrong.

Step 1: The Sound Test — Diagnose Before You Touch Anything

Before opening a panel or ordering a part, listen to what the grill does when it tries to feed. This single test sorts almost every case into the right bucket:

• Motor hums but the auger doesn't move → jam. This is the most common outcome by a wide margin.
• No sound at all → motor failure, a disconnected harness, a blown fuse, or a controller issue.
• Clicking or grinding → something is physically obstructing the auger — a wood chip, a bolt, a piece of packaging debris.
• Motor spins normally but no pellets appear at the firepot (Pit Boss specifically) → check the shear pin before anything else.

Run this test with the hopper lid open and a flashlight so you can see the top of the auger while the grill attempts to feed. It costs nothing and immediately tells you which section below to read.

Auger Not Turning At All — Causes & Fixes

If there's genuinely no sound and no movement, work through this list in order — it's roughly sorted from most to least likely:

1. Power connection. Confirm the grill is actually receiving power and the controller display is lit. A tripped GFCI outlet is a common, easily overlooked cause.
2. Blown internal fuse. On both brands, the fuse behind the control panel fails more often than the motor itself. It's cheap and takes minutes to check with a multimeter — do this before ordering a motor.
3. Disconnected wiring harness. Open the service panel and confirm the motor's molex connector is fully seated. Vibration during shipping or transport can work these loose.
4. Missing or bent auger motor pin (older Traeger AC grills). A small pin behind the motor couples it to the auger shaft. If it's missing, bent, or broken, the motor can run with nothing turning.
5. Sheared shear pin (Pit Boss). Same concept as above but standardized as a real replaceable part — covered in its own section below.
6. Seized auger from a hardened jam. If the shaft itself won't turn even by hand, you're likely dealing with pellet "concrete" from moisture exposure — covered next.

Both manufacturers include a built-in diagnostic for this: Traeger's Self-Test (Menu > Maintenance & Care > Self-Test) runs a roughly 10-second check of the auger circuit and reports whether it passes.

Traeger "Auger Overcurrent" — What It Actually Means

This error is specific to WiFIRE-enabled (D2) Traeger grills, and it causes more unnecessary anxiety than any other auger message. According to Traeger's own support documentation, the error fires when the controller detects abnormally high current draw from the auger motor — a signal that it's jammed or damaged. Critically, Traeger states plainly that this is "almost always" caused by wet pellets, with foreign objects like charcoal or wood chips as the second most common cause.

In other words: Auger Overcurrent is a jam alert, not a death sentence for the motor. The grill stops the auger, pushes an app notification, and begins a shutdown sequence to protect the motor from burning out under sustained load — which is exactly why you should clear the jam immediately rather than assume you need a new motor.

What to do when you see it:

1. Unplug the grill and let it cool if it was actively cooking.
2. Open the hopper and visually check for wet, swollen pellets, sawdust clumps, or anything that isn't a whole pellet.
3. Run Clear Auger from the menu (Menu > Auger > Clear Auger). On D2 controllers this reverses the auger for 10 seconds, pauses briefly, then runs forward for 12 seconds, repeating in that cycle. Let it run — this can take 15 minutes or more to fully work a stubborn jam free.
4. Once it's clear, run Prime Auger to refill the tube before your next cook.
5. If Clear Auger runs but the auger still won't turn afterward, that's when motor or wiring failure becomes the more likely explanation — not before.

Also watch for Error 0013 / ER13 (Auger Motor Disconnected), which is different from Overcurrent: it means the controller isn't receiving tachometer feedback from the motor at all, usually from a loose connection rather than a jam. Reseat the harness first; if the code persists after that, the motor itself likely needs replacing.

One more thing worth knowing before you crack open the hopper: grills manufactured before June 2023 (date code 2305 or earlier) use screws that strip easily with a standard screwdriver on the service panel. Traeger recommends a manual impact driver for these units and will mail one out on request — don't force it with a regular Phillips head.

Clearing a Jam — Wet Pellets, Sawdust & Foreign Objects

Jams are overwhelmingly a moisture problem. Pellets are compressed sawdust; the moment they absorb humidity — from a leaky hopper lid, condensation, or storage in a damp garage — they swell and can fuse into a solid mass that behaves like wet concrete inside the auger tube.

For a straightforward jam (loose swollen pellets, not fully hardened):

• Empty the hopper completely and inspect for anything that isn't a dry, intact pellet.
• Manually rotate the auger by hand if accessible, working debris back toward the hopper rather than forcing it down.
• Run Clear Auger (Traeger) repeatedly, or manually cycle the motor via the Prime function (Pit Boss) between manual clearing attempts.
• Reload with fresh, dry pellets only after confirming the shaft turns freely.

For a hardened "concrete" jam, Traeger's own official escalation for non-WiFIRE AC grills is refreshingly blunt: place a length of wood — a 2x4 works — against the end of the auger motor to protect it, then strike the wood with a mallet or hammer with enough force to break the jam loose. This looks aggressive, but it's the documented manufacturer-approved method for AC-motor grills when milder measures fail.

On Pit Boss units, hardened jams often require removing the auger housing entirely — laying the grill on its side, pulling the control board and access panel, unscrewing the auger collar, and using a pipe wrench to back the shaft out of the tube for cleaning. It's more physical than the Traeger process, but it's the same underlying problem.

Prevention matters more than any fix here: keep the hopper lid closed and dry, use a cover, store pellets in a sealed container, and never let a bag sit exposed after opening. If you're between cooks for an extended stretch, running the hopper empty rather than leaving pellets sitting is cheap insurance.

Not Feeding Pellets — When the Motor Spins But Nothing Comes Out

If the motor is clearly running (you can hear it or see the rear fan spinning on AC models) but pellets aren't reaching the firepot, the auger itself has decoupled from the motor somewhere in the drivetrain. This is a different failure mode than a jam, and it points toward:

• A sheared shear pin (Pit Boss) — covered in detail below.
• A broken or missing auger motor pin (older Traeger AC units).
• Stripped plastic reduction gears inside the gearbox, usually a downstream consequence of the motor stalling against a jam for too long and overheating the internal gearing.

The distinguishing test is simple: if you can see or feel the auger shaft turning at the hopper end while the motor runs, the coupling is intact and you likely have a gearbox problem. If the shaft isn't turning at all despite the motor clearly running, the pin or coupling has failed.

Pit Boss Shear Pin Failures — Check This Before Buying a Motor

This is the single most Pit Boss-specific failure mode covered here, and it's also the cheapest to fix. Pit Boss deliberately engineers a shear pin (sometimes called a shear bolt or set screw) into the connection between the motor and the auger shaft. It's designed to fail before the gearbox does when the auger jams — protecting a $30-$50 part by sacrificing a $2 one.

If your Pit Boss motor spins freely but the auger doesn't turn, check this pin first. It's a fast visual and physical check, and replacing it is dramatically cheaper and simpler than replacing the motor.

Specs: OEM-style replacement shear pin and mounting bolt, multi-pack, compatible with Pit Boss auger drivetrains using the standard shaft coupling design.

Positioning: budget — this is the cheapest possible fix in this entire guide and should be your first purchase if the motor spins but the auger doesn't.

Check Price on Amazon

Pros:

• Inexpensive relative to a full motor replacement
• Direct fix for the most common "motor runs, auger doesn't" Pit Boss symptom
• Worth keeping a spare on hand once you've replaced one

Cons:

• Only addresses the pin — won't help if the gearbox itself has stripped
• Multi-pack sizing varies by listing; confirm fitment for your specific model before ordering

Verdict: If your Pit Boss auger motor runs but nothing feeds, check and replace this pin before assuming you need a new motor.

Perfect for: Pit Boss owners troubleshooting a spinning-motor, stationary-auger symptom.

Don't Confuse These: Pit Boss "Err" / "Er1" / "ErL" Codes

This is one of the most common misdiagnoses in Pit Boss troubleshooting, and it's worth its own section because it sends people shopping for a new auger motor when the auger was never the problem.

Codes like Err, Er1, and ErL on Pit Boss controllers indicate that the controller has lost its read on the RTD temperature probe — not the auger. When the controller can't confirm an accurate temperature reading, it halts the auger as a built-in safety measure, since feeding pellets without reliable temperature feedback risks a runaway fire. The symptom looks identical to an auger fault from the outside — the auger simply stops — but the root cause and the fix are completely different.

If you're seeing one of these codes, check the temperature probe and its wiring connection before touching the auger motor at all. Related but distinct codes worth knowing:

• Er2 — fire not established during startup (empty hopper, unprimed auger, or a failed hot rod igniter), not an auger fault itself.
• ErP — improper shutdown from a power interruption; usually resolved with a simple reset.

The broader lesson applies to Traeger too: not every stopped auger is an auger problem. Confirm the actual fault before ordering parts.

Motor or Gearbox Failure — When You Actually Need a New Motor

After working through the sections above, replacement is the right call when:

• Clear Auger (Traeger) or manual clearing (Pit Boss) has been run successfully, the tube is confirmed free of debris, and the auger still won't turn.
• The shear pin (Pit Boss) or motor pin (older Traeger) is confirmed intact and properly seated, yet the auger doesn't move when the motor runs.
• You can hear or feel grinding from the gearbox itself rather than a clean hum, suggesting stripped internal gears — a common secondary failure after a motor has stalled against a jam for an extended period and overheated its windings.
• Self-Test (Traeger) fails after all wiring and jam checks pass.

A properly maintained auger motor on either brand can reasonably be expected to last several years under normal use. Most failures that do occur trace back to a motor that stalled against a jam repeatedly rather than straightforward wear — another reason clearing jams promptly, rather than repeatedly powering through them, protects the motor long-term.

Positioning: premium — a "refresh everything" option, not a targeted single-part fix.

Check Price on Amazon

Pros:

• Saves repeated teardowns if several components are near end-of-life together
• Reasonable option for an out-of-warranty grill you plan to keep running for years
• Covers the core wear parts in one order

Cons:

• Overkill if the auger motor is your only actual failure
• Higher total cost than a single-part fix

Verdict: Worth it for an older, out-of-warranty grill showing multiple age-related symptoms — not the right first move for an isolated auger issue.

Perfect for: Owners of grills past the 5+ year mark doing a full internal refresh rather than a single repair.

If you'd rather go the OEM route, Traeger's D2 auger motor (KIT0577, used across Pro 575/780, Ironwood, Timberline Gen 2, Silverton, and Century 885) and Pit Boss's OEM auger motor aren't reliably listed on Amazon under a stable ASIN — search current OEM Traeger auger motor listings here or search current Pit Boss auger motor listings here and confirm the part number matches your grill's specific model before buying.

Preventing Auger Problems Before They Start

• Keep water out of the hopper. This is the root cause behind the large majority of jams on both brands. A tight-fitting lid and a grill cover go a long way, especially if the grill lives outdoors year-round.
• Store pellets dry. Once a bag is opened, keep it sealed in a container, not left open in a garage that sees humidity swings.
• Never load foreign material into the hopper. Wood chips, charcoal, or anything that isn't a whole wood pellet is a jam waiting to happen — this applies even to small quantities mixed in for flavor experiments.
• Empty the hopper during long storage gaps. Pellets sitting unused for weeks are more likely to absorb ambient moisture than pellets being cycled through regularly.
• Keep a spare shear pin on hand (Pit Boss). It's inexpensive and the fix takes minutes once you have one.
• Don't power through a jam repeatedly. Letting the motor stall against resistance over and over is what strips gearboxes and shortens motor life — clear the jam properly rather than cycling the auger against it.

For general upkeep beyond the auger specifically, see our complete pellet grill cleaning guide — a lot of auger issues start with the same moisture and debris problems that cause firepot and hopper buildup elsewhere in the grill.

Frequently Asked Questions

Conclusion

The pattern across both brands is consistent: a stopped auger looks alarming, but it's rarely the motor. On Traeger, "Auger Overcurrent" is a jam warning far more often than a hardware failure — clear it, check for wet pellets, and prime before assuming the worst. On Pit Boss, check the shear pin before you check anything else if the motor is clearly running. And on either brand, don't let an unrelated code — Pit Boss's probe-fault errors especially — send you chasing an auger repair you don't need.

Reserve an actual motor replacement for the cases where you've ruled out a jam, confirmed the pin or coupling is intact, and the auger still won't move. At that point, a direct-fit universal motor is a straightforward fix, and a full refresh kit makes sense if your grill is old enough that other components are aging alongside it.

If auger trouble keeps recurring on the same grill, it's worth reading through our breakdown of common reasons a pellet grill won't heat up, since feed problems and heat problems often share the same root causes — and if you're deciding between platforms altogether, our Traeger vs. Pit Boss comparison covers long-term reliability differences that matter more than spec sheets once you've owned either grill for a season or two.
