I have no power to my ac/heat digital stat, Ive replaced breakers and unit fuses, power noted to unit at fuses.. not sure what to test next... this happened after night of storms

Check your control board in the bottom of your furnace. It may have a 3 amp car type fuse on it.

Check for a small 3amp fuse on the furnace control board. Please let us know what make of furnace you have.

Guess were on the same page Josh, lol.

Looks that way. I just typed faster. Lol

What does the fuse look like? I am experiencing the same issue. This may be my answer.

Many times the fuse has blades that plug in like a automotive fuse style.

And other times they have a cylinder glass fuse, either on the board, or inline between low voltage side of transformer and board.

If you own a volt\ohm meter I would see if you have 24 volts from your transformer if the fuse is good. If not replace the transformer and remember to install a fuse if one is not already there, on the hot side of the transformers secondary voltage.

Guys,, this question was posted May 11.., hope by now the problem is fixed

I also hope it has been fixed. Somehow these old posts keep coming back. LOL
