HI. My pellet stove seems to do everything right until it's time to blow hot air into the room. I have a quadrafire 1200 classic bay insert. The fire starts pellets feed but the blower never starts. I bypassed the snap disk 1 and that didn't help. I bought a new convection blower and that doesn't help. I don't want to replace the control box but is that my next option? Any ideas what is going on? Thanks in advance.
