In some trailer models, Keystone installed a "resettable 12 volt fuse" in the 12 volt distribution panel inside the trailer power center. In other trailer models, Keystone installed an "instant blow 12 volt fuse" and in other trailer models, they installed a "delayed blow 12 volt fuse". The resettable fuses in some applications will blow prematurely, shutting down the furnace. By the time you get to the fuse to check it, it's already reset and working normally, so it is difficult to identify that it is what's causing your "furnace shutdown".
Check your 12 volt distribution panel for a "12 volt resettable fuse". If there is one installed in the furnace fuse position, replace it with a "plastic 12 volt fuse" of the proper amperage and try the furnace again...
Here's what you are looking for and a normal 12 volt fuse to compare.
