Re: Atwood 8500 series furnace bench test on high limit switch
Okay thank you. That's what I was afraid of. I did that and nothing happened. Verified 13+ volts to the positive and negative lead. No noise or anything from the furnace. I am going to check all the connections, but it seems like I may be buying a dinosaur board to replace mine.2.1KViews0likes0CommentsRe: Atwood 8500 series furnace bench test on high limit switch
Hello, I know this is an old post, but I have the exact same furnace and need to bench test it. I am unsure what to do with the blue thermostat wires. I applied 12V to the positive and negative wires, but I am not sure what to do with the 2 thermostat wires. Do I need to connect them together? Or do they get supplied with 12V? They are both blue, does the polarity matter if I am supposed to be connecting them to 12V?? Thank you.2.1KViews0likes0Comments
