24V transformer warm to touch
I have a 24 volt transformer mounted on the gangbox that the furnace switch sits in. My son thinks it either controls the low voltage of the furnace or a humidifier.
The transformer is warm to the touch and the metal box its mounted on is slightly warm to the touch as well.
Does this sound normal?
FWIW:There a similar transformer that controls the doorbell elsewhere and it too is slightly warm to the touch but a bit less than the in question.
