Good morning!
My board, a 50A50-473, went bad in my Trane XE80. I replaced it with a 50A55-3797.
Everything works fine, except the transformers hums when the unit is at idle.
Will a transformer run all the time with different boards? What could I have possibly wired incorrectly if not?
Thanks in advance for the help!
