The fridge has been my biggest challenge since day one. When we first bought the trailer we took it straight to an RV dealer because we wanted it checked out for safety and to make sure that key systems were working. They said the fridge was totally dead and they just happened to have almost the same model for sale used ($$$). Scared by the price we just took it back home and packed it full of blocks of ice and used it like an ice chest on our first few trips that summer.
The second year I started troubleshooting and right away discovered that almost every wire in the back was plugged into the wrong place, I found a service manual online and started putting wires back into the right places, replacing fuses, and then eventually two circuit boards I found online until I got the electric side working. After that we could camp anywhere that we could plug in, that felt like such an upgrade from the ice blocks.
This year I wanted to see if I could get the gas side of the fridge working and totally expected that I might have to go searching for another part somewhere online. Today I started troubleshooting and vowed that I would start at the beginning, go slow, and troubleshoot each part. Well 3-4 steps into the process I found a problem and spent a few minutes trying different things until BAM it started working. Now I have a dual mode fridge again. So damn pleased with myself :)
Now going back to the beginning of the story about the RV dealer, the eager offer of another overpriced used fridge, and the jumbling of ALL the wires in the back. Well guess what was keeping the gas side of the fridge from working? Would you believe two wires on the gas valve were reversed? Propane was getting to the valve, but the valve was electronically closed because the wires were reversed. No marking on the wires indicated which contact was correct so I had missed this during my initial rewiring session of a few years ago. Come on, it's VERY FISHY when every single wire on the back of this fridge has been in the wrong place since that visit to the RV place.
Well I think I'm gonna go camping in a week or two :)
And this time we are going off the grid, solar for the lights and propane for the fridge.
