We have a 2017 pdvc Englander Pellet Stove. Brand new freshly installed as of September 2018. This fall we cleaned out the whole thing to get it ready for winter use. And it worked fine until 2 weeks ago. It had an issue with shutting off, and the convection blower not working. Trimming the frayed end of the vacuum shutdown switch hose that seems to have fixed the shutting down. But the convection blower is of course still an issue. We have all fresh gaskets and cleaned system. But can not figure out what the problem is. We don't want to just spend the money and replace the blower straight away. Any ideas on what we can try?
