The common causes of king pellet stove shutting down are:

  • Poor air adjustment
  • A dirty team
  • Inadequate heat trips the stove’s sensors

Also, the furnace’s broken part and work down may cause its constant shutting down. 


Most likely long pellets are the culprits of auger jamming or shutting down the stove.

But the solution is simple also—concise the long pellets of the furnace into a manageable length. You can concise the size of the pellets by dropping bags on the floor.

4. King Pellet Stove Excessive Clinkers

The airflow leak in the king pellet stove is most likely responsible for the excessive clinkers. The partially or burned pellets formed the clinkers. 


If your king pellet stove has excessive clinkers, you can solve the problem by following several general rules.

The easy solution includes cleaning all vents and adjusting the airflow setting or damper. Finally, solve the problem by checking all gaskets and taking steps to repair/replace them if necessary. 

5. Low Heat Output Of Stove

The stove’s produced heat rate or ignition rate is proportional to the fuel rate. Therefore air-to-pellet ratio is the likely culprit if your king pellet stove has a low heat output rate. 


If your king pellet stove is suffering from an air-to-pellet ratio problem, the solution is to adjust it by increasing the airflow. Further, you can increase the stove’s feed rate to adjust the Air-to-pellet ratio. 

6. Lazy Flame

You will not get your required heat if your stove has a lazy flame, which may lead to shutting down the furnace.

Most probably, the following factors are responsible for the King pellet stove lazy flame:

  • The neglected or unclean pellet stove
  • Harmful blower exhaust
  • Poor air-to-pellet ratio

First, properly clean the pellet stove and increase the air adjustments by increasing airflow. Further, decrease the feed rate to increase the stove flame. 

7. Stove Blackened Glass

  1. We bought our first pellet stove several years ago Haven’t used all that much each winter but yesterday it was working fine (but our pellets bags are 2 years old now) for several hours. I clean the chamber really well after each use. Then it shut down, gave Er 2 message. I shut it off and the pot kept burning down. Smoke started coming out of the Air Intake at the back of the unit. Filled the barn room with lots of SMOKE! I took pictures of the back of it!

    What in the world does that mean? It was scary. Thank you for your help. Nancy

  2. I can’t get my king pellet stove model 5500m to come on. I tried pushing the up and down auxiliary buttons but nothing happened,

  3. Cleaned out my king 5502M pellet stove and started it up, it ran normal for about 12 hours or so then I came home and th hopper was over filled and smoldering. The glass was all black. I shut it back down and let it all cool off. The next day I cleaned out the chimney and inside the stove. The hopper is full and turned it back on and it won’t load pellets now or do anything. I am not sure where to go from here, please help.

    • Hi Alison

      Your pellet stove stops feeding pellets due to one or more issues like an empty hopper, a bad thermocouple, a jammed auger, a failed auger motor, restricted airflow in the pellet stove, a faulty high limit sensor, and fuel in the hopper.

      As your stove’s hopper is full, check the other issues and fix them by following our guide on Pellet Stove Auger Stops Feeding Pellets .

      Hopefully, you will get the solution.

      Wish you all the best.
