- Hello to all , I am a new member so hope this question hasn't been addressed already! We have a Harmon PC 45 pellet stove and it has worked great for the last year! Today I did a cleaning and after could not get the distribution blower to kick in! The stove would shut off and a 6 status light would come on! I did shove a shop vac hose into the stove pipe too clean it ! I wonder if in doing so it did some damage to the sensor in there? I did notice in cleaning it , seemed to be a lot of build up on the walls and moisture ! Our temperatures have been cold and maybe condensation is getting in! We have an outside air vent as well! Any help would be appreciated! Thanks!
