i have an Avalon Astoria Bay wood pellet stove on a skytech wireless digital thermostat. Stove has operated awesome but on occasion we run into a particular scenario. It appears that when the House reaches the set temp the stove begins to shut down and no element is lighting the pellets. This is expected with the exception that the auger continues to pile in pellets into the firebox. Shortly after the stove goes into a non operating mode and will no longer light up per the thermostat. I have to reset it at now I have a large pile of pellets being lit up. There is a large plume of smoke and large flame and consequently a worry since the flames are consuming the box. Once the pellets are burned off the stove operates as expected. Please help.
