Comfortbilt Pellet Stove Problems [5 Easy Solutions]

This chapter will let you know the common pellet stove issues and how you can solve them. 

01. Stove Won’t Turn On 

Your pellet stove won’t turn on or ignite due to power supply issues. A blown fuse is also responsible for this stove problem. Therefore, a damaged power cable, gray ribbon data cable, or main harness wireline can also prevent your stove from turning on. Lastly, a defective control panel is responsible for the stove issue. 

Solution: 

Firstly, check the outlet you use to plug the stove. If it is well, ensure you turn the on/off rocker switch to the On position. Secondly, inspect the fuse in the back of the power switch. If it gets blown out, replace it with a new one.  Don’t forget to check the power cable, gray ribbon data cable, and harness wireline. If they get loosened, connect all of the cables securely. And finally, replace the control panel if needed. 

02. Excessive Smoke During Startup

Excessive smoke comes out of your pellet stove during startup due to the following reasons:

  • A weak or misaligned igniter
  • Insufficient airflow

Solution:

Ensure you start up the pellet stove in heat level 3 if you turn the stove on in Manual mode. It will allow sufficient airflow for proper combustion. Secondly, check the igniter position of your Comfortbilt Pellet Stove.

You should correct the igniter position if it gets misaligned. Igniter troubleshooting tutorial to learn how to position the igniter correctly. If the interior air pathways and channels get dirty, it causes airflow issues. Use an ash vacuum to clean the interior chamber once a week to keep it dirt-free. 

03. Chirping Noise Coming From Auger Area

Your ComfortBilt Pellet Stove will make a humming or squeaking noise if:

  • Dirt, sawdust, or moisture may build up in the auger housing or around the fighting of the auger bit.
  • Foreign objects like nails or screws may get mixed in with the pellets 
  • One of the two bearings may get compromised

Solution:

You can use a rubber mallet to knock some of the dirt & debris deposits if the buildup is not too severe. Just grab the rubber mallet and tap on the cylindrical auger housing on the top and bottom of your stove. 

The pellet stove will also make the chirping noise if dirt builds up at the top of the chute. Regarding this, run a long rod up the pellet chute to loosen the build-up from the chute.  It may require you to remove the auger bit from the stove if there is severe buildup. You can hire a professional in this case to pull out the auger bit for thorough cleaning. 

04. Burn Pot Is Backing Up With Pellets

Improper fuel-to-air ratio caused by the airflow restriction can be the main culprit behind the burn pot backup issues. Therefore, a lack of air pressure, a clogged burn pot, and improper auger feed rate are also responsible for this stove issue. 

Solution:

The backing-up issue will happen due to an airflow restriction. And the airflow problem will occur if dirt or dust builds up in the rear airflow chambers. Clean the ash or dust buildup from the rear airflow chamber using an ash vacuum. 

On the other hand, you should adjust the auger feeding rates if you encounter the backing-up issue since installation. Lastly, ensure you seal the air chamber area properly. 

05. Stove Gives Over-temp/Overheat Alarm and Shut Down

Your pellet stove will give an overheating of over-temp alarm if: 

  • The room blower fails to move enough hot air out of your stove.
  • Limited Airflow
  • Improper fuel-to-air ratio

Solution: 

  • Make sure the room blower functions properly. Flick the squirrel-cage style fan manually if it is not spinning freely.
  • Unclog the rear airflow chambers to draw sufficient air
  • Adjust the auger feeding rates and exhaust voltages

    • Hi Lonnie

      Malfunctioning of your stove and overheating issue is shutting off your stove when the blower starts. Plus, if the limit switch is defective, your stove will go out.

      Also, blocked air filter, dirty or faulty flame sensor, trouble with flame rollout switch, and defective control board can be responsible to shut off. Now check and find out which one is causing you to shut off your stove and fix it. First, try cleaning the flame sensor and air filter. Then try the rest issues to fix. Plus, you can read our guide why pellet stove keeps shutting off and how to fix.

      Thanks

  1. I just purchased my Comfortbilt pellet stove in December 2021. It started to make a pretty loud noise yesterday morning that woke us up. The noise sounds like a squeaking board or farting sound. It happens approximately every 8 seconds. Very annoying! Had to sleep with our stove off last night, which made the house pretty cold. We have been cleaning the stove daily to every other day. Have never let it go past 2 days without cleaning it. Any idea what the problem could be. It’s essentially a new stove…..

    • Hi Darlene

      Generally, this type of issue happens due to dirt or clogged system, unlevel mechanics, loose mechanics, or faulty airflow.

      As your pellet stove is clean, check for other issues and fix them if you get them defective.

      If it doesn’t work, take help from the Comfortbilt customer service center.

      Wish you all the best.

    • Going through the same problem currently. Pretty sure it’s the auger but haven’t received a reply from the company on troubleshooting it.
