Let the appliance cool, then empty the hopper and check for fines and swollen pellets before assuming a part has failed.
A pellet stove that will not feed has stopped somewhere along a short chain: hopper, auger, feed motor, control board. The most common cause is not a broken part at all. It is fuel. Fines, the sawdust that collects at the bottom of a bag, pack around the auger and bind it, and a bag that has taken any moisture will swell and jam it outright. Beyond fuel, the auger motor can fail, the control board can stop calling for feed, and a safety interlock can be holding the appliance off because some other condition is not satisfied. That last one catches people: many pellet stoves will not feed if the exhaust path is blocked or a door is not sealing, because the appliance has decided it is not safe to add fuel.
So a feed failure is often a symptom of a venting or gasket problem instead of a feed problem.
Checks you can do safely
- Empty the hopper completely and look for fines, swelling or foreign objects
- Check whether the auger turns at all when the appliance calls for fuel
- Confirm the door and ash pan close and seal correctly
- Check the burn pot air holes are clear
- Note any error code exactly as displayed
- Try a fresh bag from a different batch before ordering parts
Pellet stove not feeding: causes in the order worth checking
Routine: worth diagnosing instead of living with
| Possible cause | Rank |
|---|---|
| Fines and sawdust packing around the auger | Most common |
| Pellets that have taken moisture and swollen in the hopper | 2 |
| A foreign object in the hopper jamming the auger | 3 |
| A failed auger motor or a slipping coupling | 4 |
| A blocked exhaust path holding the appliance in a safety state | 5 |
| A door or gasket not sealing, so the vacuum switch will not close | 6 |
| A failed vacuum switch, sensor or control board | 7 |

Common questions about pellet stove not feeding
What are fines and why do they matter?+
Fines are the sawdust that settles at the bottom of a bag. They pack around the auger flighting and bind it, and they burn differently from whole pellets. A hopper filled straight from the bottom of a pallet is a classic cause of a feed problem.
Can damp pellets jam it?+
Readily. Pellets are compressed sawdust and they swell when they take moisture, which is enough to lock an auger. Storing bags on a damp basement floor or in an unheated shed is how it commonly happens.
The auger does not turn at all.+
Either the motor, the coupling, a genuine jam, or the appliance intentionally not calling for feed because a safety condition is unmet. Establishing which one it is comes before ordering parts, and the error code commonly narrows it.
Why would a blocked vent stop it feeding?+
Because a pellet appliance monitors whether it can move exhaust, and if it cannot, it stops adding fuel, not filling the burn pot with unburnt pellets. The appliance protecting you, and it means the real fault is in the vent.
It feeds but the fire keeps going out.+
That points at air instead of fuel: a clogged burn pot, a loaded heat exchanger, a leaking door gasket or a fouled vent. The appliance is getting pellets and cannot burn them correctly, which is a different fault from a feed failure.
Should I try a different brand of pellets?+
A cheap and informative test. If a fresh bag from a different batch changes the behaviour, you have your answer. Ash content and fines vary considerably between brands and between batches of the same brand.
Can I clear the auger myself?+
Emptying the hopper and clearing loose fines is reasonable with the appliance cold and unplugged. Anything involving removing the auger assembly is a service job, and reaching into a hopper on a powered appliance is not something to do.
What does the error code tell me?+
Quite a lot, and it is worth writing down exactly, not paraphrasing. Codes are model-specific and they distinguish between ignition failure, exhaust pressure faults, over-temperature and feed problems, which are four different visits.
How often does this trace back to cleaning?+
Often. A large share of pellet appliance faults are an appliance that has never had a genuine deep service: heat exchanger, ash traps and vent, not the weekly burn-pot scrape. Ash accumulation causes the conditions that trip the safety states.
The stove is fifteen years old. Do I fix it or replace it?+
Age matters far less than whether the manufacturer still supplies parts. A solidly made appliance that can still be fed components is ordinarily worth keeping going. Establish whether the auger assembly and the control board are still available before you commit to any labour.
Should I run it while I wait for service?+
If it will not feed, it will not run. If it feeds intermittently, do not. An appliance cycling in and out of safety states is telling you a condition is unmet, and forcing it through is how a fault becomes a bigger one.
How do I avoid this next season?+
Store pellets somewhere dry, avoid tipping the last dusty portion of a bag into the hopper, and have the full service done before first firing instead of after the first breakdown.
