Anyone ever had a problem with constant pellet feed on the serenity? The problem I have is when the stove acts up the auger keeps feeding pellets into the burn pot (alot of fire and smoke). The INTERFACE MODULE and the CONTROL HEAD have both been replaced with new ones and i am still having this issue. Tried to stop the pellet feed by lifting the lid on the hopper to disengage the switch but it still keeps feeding pellets. When I pushed the power button to turn the stove off it even keep feeding pellets during shut down mode. Also the auger indicator light on the control head comes on every few seconds, like it should, but it is still constantly feeding pellets. When the stove acts up either the blower motor or exhaust blower fluctuate in speed and that is how i know there is a problem with it feeding pellets. I run the stove in manual mode on power level 1 or 2. Kinda nervous about leaving the house with the stove unattended until this problem is resolved..
