Question
http://www.heatinghelp.com/files/articles/768/216.pdf I have a very old Honeywell furnace with the old mercury limit switches. The furnace works great but the blower suddenly won't shut off. We checked to make sure it's not a thermostat issue, and December is certainly not a good time to replace a furnace financially or temperature wise because this thing is huge! Ay help you could offer would be appreciated

Answer
Meredith,
I don't know what your furnace is? Honeywell never made a furnace, Also I don't know how old "very old" is? within ten years might help know what type of fan control it has?
Don't know what you did to check the thermostat either, or if it's a heating and cooling thermostat or heating only? By the way how big is "huge:.
