Santa Fe freestand installed 5 weeks ago. Runs and heats great but in the last few days it seems to get confused about starting when the call for heat comes on. I don't see any pellets coming in and it just seems to be not working towards starting. I hit the reset button and all seems fine after that. Any thoughts on this? I am afraid that this can happen during the day when I am not home and I can't reset the button. Just what does the reset button do? Other than this problem I am more than pleased with the unit. I have run maybe 25 bags through it. Suggestions anyone?
