Need HVAC/Furnace Help - Furnace Dead

[hghclsswhitetrsh]

Is there anyway possible that you damaged the wiring by pulling the new one, creating a short. I'd start by pulling the wires off both ends and test ohms Red to green, red to yellow, red to blue, red to white red to green. Then green to yellow green to blue green to white etc etc etc.

Also I didn't see a fuse on the board, is there and I just missed it?

Okay continuity test on all the wires in the 18-10 came back good. So this is definitely at the furnace. Thank you everyone for all your inputs.

Anyone got one of these handy? Reads 250V @ 2A.

Tiny little bugger.

On a serious note. For anyone reading this who has to replace thermostat wires. Tape the old to new before pulling the old out.

Believe it or not homedepot has them.

Negative on Home Depot, Lowe's, Ato Zone, and Napa. Rat Shack is next. If all else fails I will rewire it to take a larger diameter fuse with the same rating.

Hmmm. I got some from the Home Depot in Lakewood. But that doesn't help you much. Better find the short or you'll have the same result.

This one is physically smaller than a 5x20, which many people carry. No biggie - I'll do a 1 1/4 inline, and put a 250V @ 2A in it.

Agreed on finding the short. I am hoping that it popped when I cut the existing wiring - I thought I had the power off when I did the cut, but I forget things a lot.
