I have a Drolet ECO-45 pellet stove I bought used a couple years ago. This is my first stove so I am still learning about it. A couple issues...the stove if run on setting 3 (out of 6) or higher after about 30-60 minutes will over heat and shut down. I believe the cause is a weak blower. The stove will only blow hot air at about 2-4 feet out of the front of the stove and that doesnt increase when you turn up the setting. I had a guy over today to service my furnace and he looked at my stove for me and said he thought the blower was bad. he said you should be able to stand back 10 feet or more and feel that hot air blow but you cant. It only extends about 2-4 feet. He also said the stove gets real hot on the sides which tells him the blower is weak and explains why it over heats so easily. Does anyone have any advice for me here?
