Dometic Fridge issue

[Chuck77]

I haven’t found this exact issue on any thread/ search yet. Hopefully someone can help.

I have a new Dometic Rv fridge. Works just fine on electric.

When I switch to propane it fires up cools off. But anywhere from 1-3 hours in, it goes into error mode with the audible beeping. It just won’t stay running on propane. I searched for leaks, stove still lights so supply is there, tanks are topped off. With all the regulator issues I even changed it out. Still won’t work more than a couple hours without going into error.

Any help would be appreciated.

Thanks.
