The furnace has started making this loud buzzing sound every time the heat is turned on. It seems to be coming from around the blower, but the blower sounds like it is working fine. Any ideas?

Hi,

Remove the control box cover and see if it is the transformer buzzing. Or a relay, contactor.


Will need furnace model number, the number you gave is the a-coil model number.



Thanks,
Robert
