Hello all I have a quadrafire 1100 insert that I had bout used.When I bought it had dealer go over it completely top to bottom he replaced the circuit board and some snap sensors.it has ran like a champ until today.Fired it up when I got home and the combustion fan was making a grinding noise that I've never heard before.it went away about 8-10 min later and is running what I call it's normal hums and moans.Do I need to start saving for a new motor(very expensive-340 on eBay )? Or do you think that the whole stove being cooled down that it was sounding like that until it was at tempature Thanks in advance.
