Pellet stoves are a great way to heat your home sustainably, but when they start consuming more pellets than expected, it can be concerning. Don't worry! There are several reasons why your pellet stove might be dropping too many pellets.
In this guide, we'll explore the potential causes and provide easy-to-follow solutions to get your stove running efficiently again.
Why is My Pellet Stove Dropping Too Many Pellets?
There are a few key reasons why your pellet stove might be overfeeding and burning through pellets too quickly:
Incorrect Feed Rate
Pellet stoves have settings that control the rate at which pellets are fed into the burn pot. If this feed rate is set too high, it will deliver more pellets than necessary, leading to excessive consumption.
Auger Motor Issues
The auger is a screw-like mechanism that transports pellets from the hopper to the burn pot. If the auger motor is malfunctioning, it can either overfeed pellets continuously or jam, causing the stove to compensate by dropping more pellets later. Worn gears or a need for lubrication can cause motor problems.
Clogged Burn Pot
The burn pot is where the pellets combust. If the burn pot is filled with ash or unburnt material (clinkers), it restricts airflow. This tricks the stove into thinking it needs more fuel, leading to more pellets being dropped.
Dirty Stove
Pellet stoves require regular cleaning. Accumulation of ash and debris in the exhaust paths and internal components will restrict airflow, causing inefficient combustion and triggering the stove to feed more pellets.
Damaged Gaskets or Seals
Pellet stoves rely on airtight seals around doors and hoppers to maintain proper combustion. If these gaskets or seals are damaged, air leaks can occur, messing with the airflow and leading to overfeeding as the stove tries to compensate.
How to Fix a Pellet Stove Dropping Too Many Pellets
Here are the steps you can take to fix the problem:
Adjust the Feed Rate
Consult your stove's manual for instructions on adjusting the feed rate. Typically, you'll find controls on the stove itself or a connected control panel. Lower the feed rate slightly and monitor the burn for an hour or two. If needed, adjust further until you achieve a good balance of flame and heat without excessive pellet buildup.
Inspect the Auger Motor
If adjusting the feed rate hasn't helped, turn off and unplug your stove. Locate the auger motor and check for any obvious signs of jams or obstructions. See your manual for guidance on safely removing and inspecting the auger. If it's worn or damaged, you might need replacement parts.

Clean the Burn Pot
This is essential! A clogged burn pot is a major cause of overfeeding. Let the stove cool completely, then remove the burn pot and scrape out all ash and clinkers. Ensure all air holes are also clear.
Deep Clean Your Stove
Follow the cleaning instructions in your stove's manual. This typically involves cleaning the hopper, internal chambers, exhaust pathways, and fans. Pay special attention to any areas where ash accumulates.

Additional Tips
Beyond the core troubleshooting steps, keep these extra tips in mind to prevent your pellet stove from dropping too many pellets and improve overall efficiency:
Using the Right Pellets
High-quality pellets made from hardwood create less ash and burn more efficiently. Avoid pellets with high dust content or those made from softwoods, as they can contribute to clogs and inefficient combustion.
