I have a three year old gnome, worked great until recently. First the igniter fuse blew out, we replaced that, did not work, replaced the igniter, it worked but would not shut off, replaced the relay switch and got a new igniter, nothing worked after that. Fuses are good, motherboard and auger function fine, we have been using the stove by igniting the pellets in the hopper and getting a good base going...any ideas as to what I need to do next to get the igniter working? Is there a switch on the mother board that has blown? Do I need a new motherboard? I can't just have a technician come over....
