After doing a little digging, it "appears" we are looking for a disk thermostat with manual reset.
What we need to figure out is the temp trip point. Too low and we get false trips. Or a manufacture number off of Rsg33's that he so graciously helped us with a pic of. As a last resort I can go operate mine on electric and then propane and read the surface temp of the sheet metal and then know to add from there.
Going to the industrial world here are 3 manufactures of these types switches. My worries about current capacity are quickly dissolving. These can come with 15 amp inductive load ratings.
Selco 1/2" disk Thermostat And the cut sheet on them
Selco catalog cut sheetAnd here is a another brand
Thermtrol and there cut sheet
Thermtrol Disk ThermostatsAnd here is another brand
Klixon brand disc thermostats and the data sheet
Klixon fixed temperature thermostats data sheet (The PDF file is large and takes a while to load)
Ideally one would want to use the same one Dometic is using. And even buy it from them. I'm out of any warranty so it's all mine right now and adding a thermal cutoff switch is purely a choice. Just like when I go to the local NAPA store to buy parts for my GM truck.
I'm not recommending anyone do anything with their unit, just passing along some investigation I have found.
Hope this helps
John
