No power to Furnace.
 
I seem to be having more trouble with this furnace. Now it doesnt have any power. It was running fine this morning, but this evening it stopped. I went down to it and noticed there was no power. I checked the fuses all checked out fine (Going into town tomorrow to get more fuses just in case.) Other then that I checked to power from the fuse box to the one unit it checked out 120 v. From there I went to the one for the chip panel and I didnt get anything. Did the switch go bad? I'm not all that sure. Any help would be great!

If the breaker is still giving 120 volts but the path is broken on it's way to the furnace than you know what to look for. If not, you have a break in the wire after breaker before furnace. Check all neutrals, especially at switches.

Thanks Doc I already checked people are telling me that it may be the Transformer. My question is if that goes out does it take out the entire system? Cause the LED light is not on and I'm wondering if that isthe culprit.

If the transformer goes out, or the fuse on the control board. You won't see the LED, it requires power from teh transformer.
