I'm having trouble thinking of how else to describe the sound that our pellet stove is making. It is a piercingly high pitched sound that appears to come from the blower.

Here's a video with plenty of awful audio (in the video I'm poking around the back of the stove, not around the blower on the far side).

Here's some more hints concerning this sound:

  • The sound started this afternoon when we restarted the stove after it had burned out.
  • This has happened once before and continued for a couple days. It went away after I cleaned and vacuumed the stove out. Sadly, that doesn't seem to have fixed the problem this time. It was not clear why the sound went away last time - I never had any kind of 'aha' moment - the sound just went away.
  • For the first 30-90 seconds of running, the stove is quiet and doesn't make this sound.
  • Turning the stove on and off has no effect.
  • It really does seem like the sound is emitting from the blower/fan.

Fans always have cheap bearings and that is what they sound like when they go.

You probably need to replace the blower.

First thing that comes up always is replacement. If you are looking how to repair and do it yourself, read on.

There are plenty of YouTube videos on how to replace, but once you have it out after removing 8 screws there are only two nuts and bolts to remove to take the motor apart.

WARNING: Use your phone to take photos before and as you take it apart. Reference counts when reassembling.

The problem is most likely gummed up bearings. Clean the shaft and the race then put oil on the bearing and reassemble. Mine works like new again, It only cost me two drops of oil and half an hour.
