Why Does My Pellet Stove Sound Like a Freight Train? Uncover the Mystery Behind the Noisy Appliance
What To Know
- If the auger is damaged or malfunctioning, it can cause the pellets to jam or feed unevenly, resulting in a loud noise.
- The bearings in the pellet stove’s fan can wear out over time, causing the fan to make a loud noise.
- In rare cases, a pellet stove may have a manufacturing defect that causes it to make a loud noise.
Pellet stoves are a convenient and efficient way to heat your home, but when they start making unusual noises, it can be a cause for concern. If your pellet stove has started sounding like a freight train, there are a few potential causes you should investigate.
1. Dirty Burn Pot
The burn pot is where the pellets are burned, and over time, it can accumulate ash and soot. This buildup can cause the pellets to burn unevenly, which can lead to a loud, rumbling noise. To fix this, simply clean the burn pot regularly according to the manufacturer’s instructions.
2. Malfunctioning Auger
The auger is the screw that feeds pellets from the hopper into the burn pot. If the auger is damaged or malfunctioning, it can cause the pellets to jam or feed unevenly, resulting in a loud noise. Inspect the auger for any damage and replace it if necessary.
3. Clogged Exhaust Vent
The exhaust vent is responsible for venting the combustion gases outside. If the exhaust vent is clogged, it can cause the stove to overheat and make a loud noise. Check the exhaust vent for any blockages and clean it as needed.
4. Worn Bearings
The bearings in the pellet stove‘s fan can wear out over time, causing the fan to make a loud noise. To fix this, replace the worn bearings with new ones.
5. Loose Parts
Loose parts, such as screws or bolts, can rattle and make noise when the pellet stove is running. Check all the screws and bolts to ensure they are tight and secure.
6. Overfilled Hopper
If the hopper is overfilled with pellets, it can put too much pressure on the auger, causing it to make a loud noise. Fill the hopper to the recommended level only.
7. Manufacturer Defect
In rare cases, a pellet stove may have a manufacturing defect that causes it to make a loud noise. If you suspect a manufacturer defect, contact the manufacturer for assistance.
Troubleshooting Tips
- Turn off the stove: Before attempting any troubleshooting, turn off the stove and allow it to cool down.
- Inspect the stove: Look for any obvious signs of damage or loose parts.
- Clean the stove: Clean the burn pot, exhaust vent, and any other areas where ash and soot may have accumulated.
- Check the auger: Make sure the auger is functioning properly and is not damaged.
- Replace worn bearings: If the fan bearings are worn, replace them with new ones.
- Contact the manufacturer: If you are unable to resolve the noise issue, contact the manufacturer for assistance.
