The blower motor will start even if I have the thermostat turned off. I have even disconnected the thermostat at the furnace and the blower motor still will start. Sometimes it will run for a few minutes and sometimes it runs for less than one minute. It will sometimes start up every 30 seconds and run for a short time. I have heard that this model furnace has had trouble with the early circuit boards and this could be the problem. Does anyone have any information on this problem? Thank you

Wow a furnace with a mind of it's own. LOL You never hear much about Jenn Air central unit I don't think it is a wide spread problem. You need to check for a stack pipe rain leak dripping on or near that board.
