My buddy has a PelPro accutron. Recently the exhaust fans has been cutting out which in turn has been backing up the burn pot and filling the house with smoke. It seems that the fan will run for 20-26 hours before it will cut out again and back up the burn pot and smoke out the house. I did a deep clean on the stove pulling out the fans and trying to ensure that it is not plugged. Is there a high temp switch that can cause this? Any help would be appreciated.

Please tell us all about the venting.
While you cleaned things did you make sure the cooling fan on the combustion blower was clean along with sucking out all of the dust bunnies and the occasional stray animal from the combustion blowers motor?
The combustion blower does normally have a thermally protected motor which will protect itself by shutting down the motor.
Venting issues can cause things to get too hot as well as can having a plugged cooling fan on the combustion blower.
Thanks for the reply. The venting is not the most ideal. It is approximately 6 feet all of which is horizontal. The room fans were also cleaned after the stove smoked out the first time. Could this venting be preventing a good draft. It is a long story as to why it is so long and rigged.

It isn't the room fan I'm concerned about it is the combustion blower the one that sucks air in and blows exhaust out.
That 6' of horizontal had better have an up bubble on it.
Most stove makers have a maximum horizontal run length of 4'
Clean the venting, the combustion blower impeller and the space between the impeller and the mounting plate, the motor and its cooling fan, and the cavity the combustion blower sits in.
Use a leaf blower from the outside to suck the crap out.
Then make certain there is at least a 1/4" per foot rise in the horizontal run. If the run isn't 4" pipe and it has to stay horizontal then change it to 4" and use the leaf blower every two to three weeks to keep it clean.
Let me guess the vent is also into the prevailing wind as well.
