I have not had to many problems with this furnace until last
Sunday morning,when I was awoken up by the smell of wires
burning,much to my surprise I found the thermostat to my
furnace smoking,and my furnace just humming,I have replaced
the thermostat, and now the furnace wont run at all,I checked
the wiring to the furnace and everything is fine,but now I have
no voltage going to the thermostat,Did something inside my
module let go or any other Ideas what could be wrong,Thank
you for any information.

Check the low voltage transformer.
