Front furnace fan running though thermostat is off (and the gas)
So our '97 Fleetwood is just sitting and I come in the garage and hear a fan running. Turns out it is the front furnace blower...I look and the thermostat/temp control is off and was last week when I was in here with no fan running...so I fool around w/the switches on/off with the front thermostat but no avail - It's an Attwood...the gas is also off so it's running and attempting to fire...(glad the gas was off). So I take off the outside cover (wasps sure like it in there and found several abandoned nests) - and the fan switch is on (on the motor outside) so I switch it off but it keeps running...finally after dinking around for a while like this I go inside and switch to 'on' the rear furnace - it does not come on but at a certain point the front fan stops...so I turn off the rear furnace at the thermostat and after a few seconds the front furnace fan starts again...repeated this and it happened again...
Can anyone help? Is this a bad thermostat, some card on the furnace (I see a few), or what? For now I have pulled the red wire going to the micro-switch which for now has it stopped.
Thanks in advance for any help you can offer...!!!
