I smelled burning wires, and then my ten-year-old trane single cycle furnace stopped working. An inducer was replaced, but the problem remains. What could have caused the burning wire smell?
A transformer can smell pretty good when it burns up. I would still recommend that a technician check that for you. It's probably not a bad idea to shut down the power to the unit if it's not running anyway.
