We have an Englander 10-CPM that is about three years old. The stove ignites and feeds properly and maintains a nice fire but the convection blower doesn't come on the way it is supposed to. Some days it works fine, and other days the stove fires up and the blower never turns on. Without the blower running it doesn't push very much heat. The blower motor itself if fine. I took it apart and cleaned it and tested it. It runs the way it's supposed to. We have tried calling the technical hotline in the manual and the number doesn't work. Anybody have any ideas?
