Exhaust blower shuts off

[DaleCjr]

i have a cb1200. The exhaust blower shuts off when there is fire or glowing pellets in the pot. But what’s weird is the heat blower is still on. I changed the 3 snap discs,thermocouple,door gasket. I also switched out computer and vacuum switch( I read that on here just to test. I know 3 people with same stove and was able to get a spare). I am at wits end and was hoping for some more input.
Thank you in advance this site has given me so much info.

Not familiar with your stove at all, but with all that you have replaced, I guess my next move would be to have someone with a multi-meter do some testing.
Have you followed the wires from the motor to make certain no wires have been subject to abrasion or other damage? Almost hints toward some kind of breaker inline to the motor or a broken wire.

you mean you tried another control box and vac switch? Or replaced them? Exhaust blower is the combustion blower, room blower is the convection blower.

Yes I tried another control box and vac switch. But I’m thinking there is to much outside air being pulled in not paying attention when doing the door seal the middle door glass seal is totally gone. So that’s where I am at. I will be off work and am gonna trace all the wires for damage.

I have but not a good look. I will be off tomorrow so I can go over it
