The ac didn't work this last summer, replace blower motor.. now heater won't fire up? pilot light is fine, thermostat is fairly new?? help me!
Therm batt? wiring?

The furnace wont run at all, or just the blower motor wont work in heating mode?

Won't fire up, combustion.. only pilot -- no blower either. But that would only blow if the heat was produced??right? If the blower will not go by itself, would be thermostat.. yes? no? Thanks! Keith

Also when I replaced motor at begining of cooling season, i belive there was some question of wiring on the blower speeds? Would that be a problem? the AC worked fine though...
