Our Dometic RM1350 4 door has had issues on and off with varying temperatures. Every time it went in for service at the dealership, no problems would show.
Two weeks ago, it began not working at all on electric. Would get an EO error but would work on propane. Back into service. At first, they thought it was the mother board but it wasn't. They removed the underbelly to track wiring and found that there was no neutral.
Placed neutral and installed new mother board and it is working fine..today.
Additional mods we are installing this weekend while camping, in hopes of frig success:
1. Adding ARP unit.
2. Adding two fans to back of frig in slide area.
3. Adding an automatic frig fire extinguisher behind frig in slide area.
We'll see how it goes.
