Convection blower not coming on

[Mab01247]

Hey all,
I have a 2007 quadrafire, MT Vernon pellet insert AE and my convection blower will not come on at all. So far ●I've replaced the snap disc
●Cleaned out the vaccumm switch and tested to make sure that the switch contacts are closed. I've checked for power at the fan and I'm getting nothing. Insert runs fine for 20-25 min until the snap disc hits the 250 degree drop tube limit and shuts down.

See page 31 of manual Snap disc # 1
Snap Disc #1 (Convection Blower) 125°FSnap disc #1 is located on the right side of the appliance on the top of the heat exchanger box. There are 2 purple wires connected to it. This snap disc turns the convection blower on and off as needed. Power is always present at snap disc #1.
