Hi all,

Upon arrival at my home I noticed the digital thermostat for my a/c / heat
unit was blank (no reading). Upon removal of the digital thermostat I
notice there is no power to any of the wires leading up to the thermostat.
There is power to the a/c unit itself, but not to the thermostat. Any ideas
why?

See if there's a fuse on your furnace unit which covers the 24-volt
supply which handles the electronics like the t-stat. Also trace the
wiring and make sure none of them has vibrated loose or broken.
