About the Transformer
A furnace transformer is the component that decreases or increases the incoming voltage to power the unit. A faulty transformer can prevent the furnace from turning on. If there is no secondary 24 volt power to the thermostat, the furnace trips a circuit breaker when it comes on, or you hear a consistent humming or vibrating noise, it's possible the transformer has failed.
