f your pellet stove shuts off after 15 minutes even though pellets are still burning, you likely need to replace the proof of fire switch (POF), also called the low-limit disc switch. Most pellet stoves have this switch installed on the blower housing with a rating that is typically around 110ºF to 140ºF.
