Your Pit Boss was supposed to make outdoor cooking easier. Set your temp, load in pellets, walk away. That’s the whole promise of a pellet grill. So when the thing refuses to ignite, throws an error code at you, or swings 50 degrees in either direction mid-cook, the frustration hits different.
The good news? Most Pit Boss grill problems aren’t catastrophic. They’re usually caused by a handful of recurring issues — a dirty fire pot, a jammed auger, bad pellets, or a temperamental igniter. And nearly all of them can be fixed at home without special tools or a service technician.
This pit boss troubleshooting guide walks through the most common issues Pit Boss owners run into, what’s actually causing them, and how to fix each one. Whether you’ve got a vertical smoker, a classic barrel-style, or one of the newer Sportsman models, these problems — and solutions — are largely the same across the lineup.
Your Pit Boss Won’t Ignite
This is the single most common complaint, and it sends a lot of people into panic mode. You press the power button, the fan kicks on, the auger starts turning — but nothing catches. No smoke, no fire, just pellets piling up in the fire pot.
Here’s the thing: when a Pit Boss isn’t igniting, it’s almost always one of three causes.
The Fire Pot Is Full of Ash or Old Pellets
Before you troubleshoot anything electronic, pull out the grill grates, the drip tray, and the heat baffle. Look at the fire pot. If it’s packed with ash, unburned pellets, or a mix of both, that’s your problem. A clogged fire pot smothers the igniter rod before it can get hot enough to light new pellets.
Vacuum or scoop out all the debris. You want the fire pot completely clean with the igniter rod visible at the bottom. This single step resolves the majority of Pit Boss not igniting issues.
The Hot Rod (Igniter) Has Failed
The hot rod is a small heating element that sits inside the fire pot. It glows red to ignite the pellets. Over time — usually after 1-2 years of regular use — these rods burn out.
To test it, start the grill and wait about two minutes. Carefully check whether the rod is getting hot. If it’s not warm at all, it needs replacement. Replacement hot rods for Pit Boss grills are inexpensive and widely available. Swapping one out takes about 15 minutes with a screwdriver.
Quick workaround while you wait for a replacement: You can manually light your Pit Boss using a small propane torch or fire starter placed directly in the fire pot. Start the grill on the “Smoke” setting, light the pellets by hand, and once they catch, close the lid and set your desired temperature. Plenty of pellet grill owners do this routinely.
The Pellets Aren’t Reaching the Fire Pot
If the fire pot is clean and the hot rod works, the issue might be upstream — pellets aren’t being fed into the pot at all. This leads us to auger problems, covered in the next section.
Auger Problems: Pellets Won’t Feed
The auger is a corkscrew-shaped metal shaft that moves pellets from the hopper into the fire pot. When it stops working, your grill starves for fuel and either won’t ignite or flames out during a cook.
Jammed Auger
Moisture is the usual villain here. If pellets get damp — either from being left in the hopper overnight or stored in a humid garage — they swell and turn to mush. That paste hardens around the auger and locks it in place.
Fixing a jammed auger requires removing the pellets from the hopper, then accessing the auger motor (usually mounted on the side or bottom of the hopper). Disconnect the auger motor and try to manually turn the auger shaft to break up the clog. In stubborn cases, you may need to remove the auger entirely and clear the jam by hand.
Prevention matters more than the fix here. Always empty the hopper after each cook if you live in a humid climate. Store pellets in sealed containers, not in the bag they came in. A five-gallon bucket with a gamma seal lid works well.
Auger Motor Has Burned Out
If the auger motor hums but doesn’t turn, or doesn’t make any sound at all when the grill starts, the motor itself may have failed. You can test this by disconnecting the motor and applying direct power to see if it responds (if you’re comfortable with basic electrical testing). Replacement auger motors are available from Pit Boss directly.
One detail that trips people up: sometimes the auger seems fine at first, but feeds pellets too slowly. This can happen when the auger tube is partially obstructed with sawdust and pellet crumbles. A long brush or compressed air can clear it out.
Temperature Fluctuations and Uneven Heat
Pit Boss temperature fluctuation is probably the second most discussed problem in pellet grill forums. You set the grill to 225°F, and the display bounces between 200 and 260. Or one side of the grill runs noticeably hotter than the other.
Some temperature swing is normal on any pellet grill — typically ±15-20°F. That’s just how the feed-and-burn cycle works. The auger feeds pellets, they ignite, the temperature rises, the controller stops feeding, the temperature drops, and the cycle repeats. You’ll see this across every pellet grill brand, not just Pit Boss.
But if your swings are larger than 25°F or the grill can’t hold a general range, something is off.
Common Causes of Wild Temperature Swings
The P-Setting Adjustment
Pit Boss grills with older controllers have a feature called the P-setting (short for “pause” setting). This controls the pause time between auger cycles when the grill is in Smoke mode. A higher P-setting means longer pauses, which means fewer pellets, lower temperatures, and more smoke. A lower P-setting feeds pellets more frequently.
If your grill runs too hot on the Smoke setting, bump the P-setting up. If it keeps flaming out, lower it. The default is usually P-4.
For a detailed explanation of how to adjust this and what each setting does, check out our Pit Boss P-setting guide.
Important note: Newer Pit Boss models with PID controllers don’t use the P-setting in the same way. PID controllers automatically regulate the auger feed rate based on the target temperature. If you have a PID controller and you’re still seeing big temperature swings, the problem is almost certainly a dirty probe, bad pellets, or a fire pot issue — not a setting you need to adjust.
Pit Boss Flame Out During a Cook
Few things are more frustrating than checking your brisket four hours in and discovering the grill went cold an hour ago. A pit boss flame out means the fire died while the grill was running.
This usually happens because of:
- The fire pot filled with ash and choked out the flame. The fix is cleaning, as described above.
- Pellets ran out. It sounds obvious, but on long cooks, it’s easy to misjudge how much fuel you need. A general rule: Pit Boss grills burn roughly 1-2 pounds of pellets per hour at smoking temperatures and up to 3 pounds per hour at higher temps.
- Damp pellets. They burn poorly, produce excessive ash, and eventually smother the fire.
- A temporary auger jam that cleared itself but starved the fire long enough for it to go out.
If your grill flames out, don’t just restart it immediately. Open the lid, remove the grates and heat baffle, and clean out the fire pot first. Restarting with a fire pot full of unburned pellets and ash is a recipe for a dangerous flare-up.
Pro Tip: For long smokes (8+ hours), set a timer on your phone to check the hopper level and fire status every couple of hours. A wireless meat thermometer that also monitors grill temperature can alert you immediately if the cooking chamber drops unexpectedly. This alone saves more cooks than any other single habit.

Pit Boss Error Codes and What They Mean
When your Pit Boss controller displays an error code, it’s actually being helpful — the code tells you roughly what’s wrong. Here are the ones you’ll see most often:
| Error Code | What It Means | Likely Fix |
|---|---|---|
| ErH | Temperature exceeded safe limit (usually 550°F+) | Grease fire or flare-up. Shut down, let it cool, clean thoroughly. Check for grease buildup on the drip tray and heat baffle. |
| ErL | Temperature dropped too low | Flame went out. Clean fire pot, check pellet supply, check auger function, restart. |
| Er1 | Meat probe malfunction | Unplug and replug the meat probe. Check for damage to the probe wire. |
| Er2 | Grill not reaching set temp within expected time | Similar causes to ErL — usually a feed or ignition issue. |
| noP | No probe detected | Meat probe isn’t connected or is faulty. |
The ErH code deserves extra attention because it usually indicates a grease fire. Pit Boss grills — like all pellet grills — accumulate grease on the drip tray and heat baffle. If you don’t clean these regularly, grease ignites and sends temperatures soaring. This is a safety issue, not just a performance one.
Warning: If you get an ErH code and see flames shooting above the grill grates, do not open the lid wide. Cut the power, close all vents if possible, and let the fire die from lack of oxygen. Opening the lid feeds the fire more air. Keep a fire extinguisher accessible near your grilling area.
The Grill Produces Too Much or Too Little Smoke
New Pit Boss owners sometimes expect billowing clouds of smoke throughout an entire cook. That’s not how pellet grills work. During the startup cycle (the first 5-10 minutes), you’ll see heavy white smoke. That’s normal — it’s the pellets initially catching fire.
Once the grill stabilizes, you should see thin, barely visible blue smoke. That’s clean combustion, and it’s actually what gives food good smoke flavor. Thick white smoke at all times means incomplete combustion — dirty fire pot, wet pellets, or restricted airflow.
If you want more smoke flavor, the Smoke setting (usually around 180-200°F) is where you’ll get it. You can also try a smoke tube — a perforated metal tube you fill with pellets, light with a torch, and place inside the cooking chamber alongside the normal fire.
For a broader comparison of how pellet grills stack up against other options for smoke production, pellet grill vs gas grill covers the key differences.
The Hopper and Feed System: Small Issues That Cause Big Problems
A couple of less obvious issues live in the hopper area.
Pellet tunnel or bridge. Sometimes pellets in the hopper form an arch or bridge above the auger opening, so the auger spins freely but doesn’t actually grab any pellets. This happens more often with smaller pellet brands or when the hopper is less than a quarter full. Give the pellets a stir occasionally during long cooks, or tap the side of the hopper.
Hopper leak letting moisture in. Some older Pit Boss models have hopper lids that don’t seal tightly. Rain or heavy dew gets in, and you’ve got a hopper full of expanded, mushy pellets that will jam the auger. If you grill outdoors without cover, investing in a grill cover or at least checking the hopper lid seal is worth it.

When the Controller Acts Strange
Occasionally, a Pit Boss controller behaves erratically — showing wrong temperatures, not responding to button presses, or cycling the auger at odd intervals. Before assuming the controller board is dead:
- Try a hard reset. Unplug the grill completely, wait 30 seconds, and plug it back in. This clears temporary glitches more often than you’d expect.
- Check all wiring connections. Vibration from transport or regular use can loosen wire connectors between the controller, fan, auger motor, igniter, and temperature probe. Open the control panel cover and make sure everything is seated firmly.
- Inspect for moisture or corrosion on the controller board. If the grill lives outside uncovered, moisture damage to electronics is a real possibility.
If none of that helps, you may need a replacement controller. Pit Boss sells them, and aftermarket PID controller upgrades (like those from Savannah Stoker) are popular for owners who want tighter temperature control than the stock controller provides.
Routine Maintenance That Prevents Most Problems
Here’s a pattern you’ll notice across this entire guide: the vast majority of Pit Boss grill problems come back to cleaning and pellet quality. A regular maintenance routine eliminates most troubleshooting scenarios before they happen.
- Vacuum the fire pot before each cook.
- Scrape the grill grates after each cook.
- Clean the drip tray and heat baffle every 3-5 cooks (more often for high-fat cooks like pork shoulder or brisket).
- Empty the hopper if you won’t use the grill for more than a day or two.
- Deep clean the entire grill interior every 30-40 hours of cooking time.
- Inspect the hot rod, auger, and fan at least once per season.
If you’re used to maintaining a Traeger or similar pellet grill, the process is very similar. Our guide to cleaning a Traeger grill covers techniques that apply broadly to pellet grills, including Pit Boss models.
FAQ
Why does my Pit Boss keep shutting off during a cook?
The most common cause is a flame out, usually triggered by a clogged fire pot, damp pellets, or an auger that stops feeding. Clean the fire pot, use fresh dry pellets, and check that the auger is turning properly. If the grill shows an ErL code, it means the temperature dropped below the minimum threshold, confirming the fire went out.
Can I use any brand of wood pellets in my Pit Boss?
Yes, you can use any food-grade hardwood pellets. You’re not limited to Pit Boss branded pellets. Look for pellets made from 100% hardwood with no fillers or binding agents. Popular options include Lumberjack, Bear Mountain, and CookinPellets. Avoid heating pellets — they’re treated with chemicals not safe for cooking.
How often should I replace the hot rod igniter?
There’s no fixed schedule. Most hot rods last 1-3 years depending on how often you grill. Replace it when it stops glowing or takes significantly longer than usual to ignite pellets. Keeping the fire pot clean extends the hot rod’s life because it doesn’t have to work as hard to ignite pellets through a layer of ash.
What’s the difference between a PID controller and a standard Pit Boss controller?
A standard controller uses a simple time-based cycle to feed pellets. A PID (Proportional-Integral-Derivative) controller continuously monitors the temperature and adjusts the pellet feed rate dynamically. PID controllers hold temperatures much more tightly — often within ±5-10°F versus ±20-25°F for standard controllers. Newer Pit Boss models generally come with PID controllers.
My Pit Boss has a strong chemical smell on the first use. Is that normal?
Yes. New grills often have residual manufacturing oils and coatings that burn off during the initial burn-in. Pit Boss recommends running the grill at high heat (around 350-400°F) for 30-45 minutes before your first cook. Don’t place any food in the grill during this burn-in cycle.
Most pit boss troubleshooting comes down to keeping the basics right: clean fire pot, dry pellets, secure connections, and regular maintenance. These grills aren’t complicated machines — they’re a motor, a fan, a heating element, and a controller working together. When one piece gets gunked up or wears out, the whole system feels broken. But the fix is almost always simpler and cheaper than it seems.
If you’re still stuck after working through everything above, Pit Boss customer support is generally responsive, and their warranty covers defective components. But nine times out of ten, a thorough cleaning and a fresh bag of pellets will get you back to smoking.
