My furnace circuit breaker is buzzing, I replaced it and it

Customer Question

Hi, my furnace circuit breaker is buzzing, I replaced it and it is still buzzing, when I unplugged the transformer, it stopped so I guess it is in the low voltage system. The buzzing is constant, the fan runs fine and the heat strips seem to be sequencing ok, but they are all on in a 30 second time, and the label reads one should take 60 seconds, the furnace heats good still. The buzzing is freaking out the ol lady!
