I have a quadra fire mt vernon AE purchased about 1 1/2 years ago. For the last 6 out of 8 mornings I have come down and stove is not running and thermostst reads "auger jammed" I will then unplug the stove so the thermo resets and the stove has run fine for the rest of the day. This has happened 6 out of the last 8 days. Any help in diagnosing this problem would be appreciated.
