Pellet stoves have gained significant popularity as a reliable and efficient heating source in many households. Homeowners seeking cost-effective heating solutions prefer these stoves due to their convenience and environmentally-friendly nature. 

However, ensuring pellet stoves’ safe and efficient operation requires proper maintenance and timely pellet stove repairs. From identifying common issues to discussing repair techniques and preventive measures, this blog provides the knowledge and insights needed to maintain a safe and efficient pellet stove.

Common Pellet Stove Problems

Problems with pellet stoves are less frequent than those with alternative heating appliances. But the frequency of problems popping up may increase if you need more maintenance on your part. Some common pellet stove problems include: 

1. Ignition Issues

If your pellet stove does not light up, it’s most likely an issue with the igniter. In most cases, people need to pay more attention to the importance of the air-to-pellet ratio, which, if not adjusted, will result in problems with ignition.

Moreover, if the ignition process is compromised, it affects the overall combustion efficiency. Incomplete combustion can result in higher emissions, increased ash production, and reduced fuel efficiency.

To avoid ignition issues, adjust the ratio by increasing airflow. The igniter should read approximately 50 ohms on an ohm meter and 2 to 3 amps on a current meter. 

It’s also essential to inspect the ignition components of your pellet stove and have it professionally cleaned once or twice a year. It ensures that your pellet stove lights up every time during the ignition process and maintains proper airflow.

2. Auger Problems

Regarding problems related to augers, jamming is the most common unwanted occurrence that pellet stove owners come across. Using long pellets often causes jamming, resulting in the stove completely shutting down. Other problems that relate to augers are motor failure and misalignment.

It’s essential to quickly fix any problem with an auger because if it fails to function correctly, it can result in insufficient or inconsistent fuel delivery to the burn pot. Those issues can cause poor combustion, reduced heat output, and an inability to maintain the desired temperature in your living space.

The best way to avoid auger problems is to use shorter pellets. If the pellets you purchase are long, drop the bag or shopper (carrying the pellet) on the floor several times. Doing so will break long pellets into manageable lengths.

It’s also important to clean the auger and the hopper to ensure efficient use of your pellet stove, especially if you use it often.
