my attic fan is supposed to run 4 hours on and then off for 4 hours....the 'deluxe blend air II system" which is part of the furnace is connected with attic fan....this is a mobile home which the attic fan runs when the furnace runs as well as runs intermitantly 4/4 all the time, or at least it is supposed to....right now it runs all the time, unless i hit the circuit breaker, keeps fan motor from burning up.

Hello edgar64

Thanks for clearifing the prior posting. I now understand what your referring to. However, as I stated in my prior posting reply, I do not have expert knowledge with that exact type of furnace and attic fan interconnection.

My guess would be the attic fan control, attic temperature thermostat control or a circuit board is defective and not allowing the attic fan to cycle on and off as it did prior.

I suggest you post the question in the "Heating and Cooling" forum and maybe in the mobile home forum. Most likely one of these forums will have a person familar with the furnace and attic fan setup you have.

In Closing
Regards & Good Luck
