Ac and fan will run perfectly but when tried to turn on furnace nothing happens. Removed thermostat to expose the wires. Connected red power wire to white wire that controls the furnace. When I connect the red wire and the white wire the furnace works perfectly
Correct me if I'm wrong the thermostat is bad and needs to be replaced
What is a good replacement thermostat for digital but not too expensive.

None taken, yes did

No offense intended but you did set the furnace temp setting to something above the current room temperature?:)

Bad stat just go to Walmart get a digital forc20 dollars then google the wiring diagram needed depending on a Coleman or domestic
