Hi my enviro ef3 stove is giving me problems now,i got home last night and looked in burn box and it was down to about 2 red embers in the burn pot and some new pellets around inside the burn pot.I emptied the burn pot and waited a few minutes and restarted it and tried twice and it would not ignite and the pellets were filling the burn pot.I tried again and the stove ignited and seems to burn fine nice flame and all.I woke this morning to a cold house and no pellet stove working now? there are fresh pellets in the burn pot and thats it where do i point myself to fix my problem?The stove is not dirty i clean it on a regular basis-could it be the exaust blower?
