Dometic RM2192 Problem, Works on AC, not Propane.

Thanks
I did find the bypass screw for my thermostat, Ranco V61 and it is in the worse possible place, the side opposite the surface I'm looking at. Will have to remove the thermostat unit to access it if I find it necessary to do that. Seems like Ranco is now run/owned by Robert Shaw Thermostats and I have been searching the web and will continue to do so to try and find someone who is selling it. If anyone knows of anyone selling a Ranco V61 or any leads please let me know.
