I have a free standing astroflamm integra pellet stove. 2 years ago I moved to a new home and took my stove with me. It sat in my garage for 2 years until I finally remodeled my basement and now installed it there. Everything works good except the convection fan. It does not respond to a change in speed when I lower or raise the settings on the user control board. The fan is getting a constant voltage between 107 - 108 volts AC regardless of what speed setting it is on. It also seems to be spinning fairly slow for that amount of voltage. For max it should be 95 V +/- 10%. I have another astroflamm intergra insert that works well and I swapped user control boards but the same is still happening on the free standing one. Could it be a faulty main control board or is it a faulty convection fan motor? The convection fan does run on plain 110 V wall AC but seems to spin slow. I guess my next step tommorow is to swap convection fans with my other working integra and see if the issue is the fan or not. Any input would be appreciated. Thanks.
