The switch enables high speed for the blower fan. Have you cleaned the flue thoroughly?

yes i have at the begining of the season
i have burned almost a ton so i didn't think that would be the cause .. i did however run the brush through it just in case but i didn't take it apart like i normally do
my stove goes out into a 90 up a foot into a 90 and a horizontal run of 2-3 feet do you think that could be it??

Is there a tee with a removable cap on the bottom?

yes why?

Did you remove it when you cleaned? You can only clean out the back of the stove up to highest level of the tee if it's never been removed and happens to be full, also removing it allows a lot of daylight in, increasing visibility in the stove while cleaning,making it easier to clean around the exhaust temp probe. If the tee is full, there is nowhere for soot to settle except higher up in the flue or back into the stove. Either way it restricts airflow, which in turn effects burning. When you clean the stove without removing the tee the soot starts depositing in the air flow right away, instead of in the tee , like a trap.
