Ok, so I think I answered my own question and thought I'd post this for anyone else who might be having a similar issue. Like I was saying my convection fan wouldn't shut off after my stove cooled down. This all started because my stove was just shutting down after running fine for a few days. Shutting down I mean the exhaust fan would shut off and the auger stopped feeding pellets. But after cooling down the convection fan wouldn't shut off. Prior to I could just unplug the stove and it would obviously shut off but when I plugged the stove back I'd have to push the power on and trip switch to start everything. The fan just only recently started to come on whenever I plugged the stove in without touching the power on.
So, I opened up the left side of my stove where the convection fan is. I had an idea from reading the trouble shooting guide it might be the snap switch for the convection fan. But even now I'm not 100% sure I'm just trying to work through this and figure it out. I've never had an issue with one of these switches before. I took some pics to post of what I've done so far. I had to move a couple of parts to access the snap disks.
So the convection fan is held in place with a small bracket that took a 7/16" socket or wrench to loosen and remove. Here's what the metal
bracket looks like.
I also had to loosen and move the control box to get the fan out. The screws to move the control box are 9/16" I didn't detach any of the wiring while doing this. But, just in case anyones wondering, yes I did unplug the stove before doing any of this. Here's a shot of the control box. The fan then easily is moved out and rested on the hearth.
Once these two things were out of the way I was able to see the two snap disks that are mounted to the exhaust fan area. The pic is where I have already removed the convection fan snap disk.
So, what happened prior to me removing the snap disk was I reached in and wiggled it a bit and the plastic portion of the disk where the wires were connected just pulled completely away from the mounting plate and the snap disk inside dropped down on the lower stove deck. Pretty sure this wasn't supposed to happen. So, here's what the disk looked like when it came apart and with the wires removed. Beside is a picture of the disk put together the way it normally looks.
I don't know much about snap disks. I'm guessing when it heats up the disk expands depressing the pin with pushes the sensor inside the portion connected to the wiring telling the fan to turn on or off. So, I don't know if you can see it in the pics below but it looks like mine has multiple hairline cracks which I imagine over time of expanding and contracting has made it to where I was just able to pull it out from the bracket.
So, I jumped on the computer and ordered a new one. Amazon had the part for like $24 with shipping. Hopefully it'll get here quick because it's kind of cold out right now. lol
To wrap up for now because this is looking like it's gonna be a two part. I'm hoping the snap disk not operating as it should allowing the convection fan to turn on and off properly will resolve my issue with the stove just randomly causing my exhaust fan and auger to stop. I'm guessing the snap disk not being able to regulate the temperature sensing the heat from the exhaust fan is the issue. We'll see. I'll try and post once the part gets here.
