We start our central heater and the furnace kicks in and then the blower starts and the house warms up but when it reaches the desired temperature. When the temp. drops and you can hear the furnace start but the blower will never kick in. If we shut off the whole thing and wait about 1 hour, we can re-start the whole thing over again and it will go through the same process. Have any idea how to fix this problem.

A new furnace will solve this problem. Just ask a local contractor... more info on the unit would be helpful... brand, model, dumb stuff like that...
