Atwood thermal cut-off issue
This one has me baffled. I had a spider web nest in the LP blow through tube causing a block. The thermal cut-off link blew as it should. I cleared the obstruction and removed the thermal cut-off (...

I do appreciate your input.
I could not see in the pic you posted which direction the tapered down side is pointing. The BRN wire or the T-stat?
Sorry, I should have said what model I have. My Atwood is a GH6-7E (Gas/Heat exchange with electronic spark). The 12 vdc comes from the switch in the coach, thru the Thermal Cut-off link, thru the T-stat and THEN to the Control BRD. If all safeties are met then the gas is turned on and the spark applied. A little different from the Electric/Gas model.
I literally removed the Thermal Cut-off link and used a wire with clips to connect the BRN wire to the T-stat. If there was a short in the BRN wire it would continue to short even with the jumper in place. I know it doesn't make since that the 15 amp fuse only blows when the Thermal Cut-off is used.
At this point I am thinking the Spark Electrode is causing some kind of load on the circuit when the Thermal Cut-off link is in and blowing the 15 amp fuse. I have a new Electrode coming tomorrow. We'll see...
OK--thanks for the Model Number but DC circuit is same...switch to thermal fuse to t-stat to board.
You state 15A fuse is blowing when thermal fuse is installed....implying thermal fuse was at issue
Now you are talking about Spark electrode.
Does the 15A Fuse BLOW when the Spark Electrode and Gas Valve DC is in ignition phase??
As for thermal fuse connection......
Clear wire/bent end connects to t-stat
Thermal Device is at other end connected to Brown wire so that IT is exposed to Excessive HEAT from blowback
