Hi - I have a 2006 Lopi Leyden.. twice now the exhaust blower has stopped working (after operating just fine for a few hours) and of course, the room quickly fills up with smoke. After the first time I made sure to thoroughly clean around the exhaust fan area... worked fine for a couple of weeks but then stopped again. Not sure if it is related but I have also noticed that the auger has stopped dropping pellets a couple times recently as well... both times I have reached in to dig out what I thought was a clogged auger and reset the cycle... but now that I think of it, both times the exhaust fan stopped about an hour later... . Any thoughts? I am planning on conducting a thorough cleaning around the exhaust motor.
