My Trane inside unit died, No blower or even power light on the control board works. I started by replacing the 115/24v transformer, then replaced the control board. Still nothing, not even the indicator light on the new board. I show 108V going into the primary of the transformer, but 0 coming out of the secondary. Is this the problem, 108 isn't enough to output 24v? By the way, I bench tested the old transformer by powering it up with 120v and iFot shows 27v of output at the secondary so I guess it wasn't bad.
