I just got a BGE and install a micro damper on it. Everything is working correctly.
Do you manually open a hole at the bottom as well as using the micro damper? I cant see to get it hot enough / bring it up to temp sometimes when it closed and only using the damper + fan at 100%.
Do I need to go the blower route? Confused why it has a hard time increasing temp.
The MD is plenty of power on a BGE or the like. Check your settings and make sure everything is functioning as it should
