RV Service and Repair??????????????

Originally my fridge wasn't cooling and I had no ammonia leak. When the Certified Dometic Tech came out and disconnected a wire and set the fridge on high cool it started cooling. I kept track of the outside temps and also the fridge & freezer temps in the morning and afternoon. It was cooling really good, like it was supposed to. I placed a household tall fan outside the MH blowing into the back of the fridge and this helped it to cool down even more. After about 3 weeks with no ammonia leak/smell I turned off the fan and a few days later my propane detector went off. I removed it and found that it was 8 years old. No smell in the MH. The next day as I walked by the MH the carbon monoxide detector was beeping. When I opened the door the smell was horrible.


Is it possible that the thing that controlled the fridge temp from going too high that was disconnected caused the ammonia leak? The Tech never came back or returned calls.
