7 Common King Pellet Stove Problems: Causes & Fixes (2024)

Encountering issues with your King pellet stove? This comprehensive guide addresses common problems like ignition failures, auger malfunctions, overheating, excessive smoke, and unusual noises. Learn how to troubleshoot and resolve these issues to keep your stove running efficiently and enjoy a warm, cozy home.

Let’s troubleshoot this together. If your pellet stove isn’t igniting, it might be as simple as the hopper being empty. Fill it up and give it a few minutes. If that doesn’t work, check the venting for blockages – sometimes the pressure switch senses a lack of airflow and shuts everything down.

If your auger isn’t moving, first, check the hopper again. If it’s full and the auger still won’t budge, there could be a crack in the hose running from the firebox to the switch, the hose barb might be clogged with ash, or the vacuum switch itself could be faulty.

And if you’re having trouble with the igniter, check for physical damage. If it’s broken, it won’t light the pellets. If there’s no visible damage, you might need to adjust the feed rate settings on your stove. This can help fine-tune the pellet delivery for optimal burning.
