If you forgot to turn off power to your air handler before replacing your stat, you probably need a new fuse.

Trane's B is Honeywell's C.

A simple test would be holding the R wire to the G wire. The fan should run.


If you have an old Trane air handler, you probably have this fuse...

Most fancoils use a 3 amp or 5 amp blade type automotive fuse available at Autozone for $3 a pack.
