This can be any 24v wire in the furnace itself so look for any pinched or scraped wires...does the gas valve have a on/off switch?
run everything the same except turn the gas valve to off...tell me if short remains.
just respond to this when ready.
ok, ill most likely be a little after 4:30, ill make sure thats the fist thing i do when i get home.
I wish you luck
I will be online later tonight and will respond as soon as possible.
thank you...dont want to cost you a bunch of fuses...
Unplug all the wires from the safetys and tape the ends of them...pretty much all we will have is the board standing alone with wires going off to the safetys...but they will not be hooked up.
remove the 2 wires from the roll out..use a paper clip as a union..slide each spade connector onto the paper clip..tape so no metal exposed
(we are bypassing the switch)...
Most shorts were on the limit switch mounted on the front wall...the switch inside would touch the exchanger...
Did you check the limit I described?
the whole idea as you see is process of elimination. Can you take a pic of the schematic and post it here?
I will stand by..
Yep....that is the famous one I was talking about.
You good now?
Thank you for your patience. Without help on your it is not possible.
Have a good night.
