A pellet stove auger funnels the wood pellets or other organic burning pellets into the burner. It's situated in the hopper into which the pellets are poured, and the feed rate is thermostatically controlled. The auger looks like a large screw-type mechanism and can become clogged or jammed from foreign objects, overfilling, or old pellets that have got moist from humidity and expanded. You must manually correct this problem.

Things you need

  1. 1

    Turn the stove off and allow it to cool fully.

  2. 2

    Remove the auger cover plate screws or nuts using either a screwdriver or a nut-driver. Remove the plate. The plate will be found at the bottom of the hopper.

  3. 3

    Clean the auger of any jammed pellets or foreign objects. Use a screwdriver to dislodge any pellets and vacuum out the area with a vacuum cleaner that has a hose attachment.

  4. 4

    Turn the pellet stove on to see if the auger turns before replacing the cover. If the auger doesn't turn after a thorough cleaning, the motor may be burnt out. Call a professional HVAC technician for further service.

Tips and warnings

  • Vacuum out an auger without a removable cover plate. Use a flashlight to look at both ends of the auger. You may be able to determine which side is jammed. Pry out any noticeable jammed pellets with a screwdriver and tap on the auger housing with a rubber mallet to dislodge jammed pellets.
