Dometic Servel RGE400 fridge too cold

Well it's been almost a year now since I revived my RGE400 fridge for a second time. As I mentioned in my last post about the fridge when I put it together the control rods were messed up and I did...

    Thanks for helping out StirCrazy!

    I finally fixed the freezing problem.  🙂

    More than 10 years ago when I was replacing the original bad thermostat I had problems connecting the
    temperature control rod to the thermostat. I gave up on it and just set the temperature blindly to something that seemed to be around 4/10 on the thermostat.
    I didn't really care about not being able to adjust the temp with the control rod because in the previous 10+ years I never touched the temp.
    When I had my cooling unit in for repairs about a year ago I must have adjusted the thermostat a bit.
    Because for the past year I had this freezing problem.

    Well a week or so ago after the new thermostat still hadn't solved the problem I decided to have a go again attaching the control rod. I found the plastic piece that was critical to connecting the rod to the thermostat. I did the whole operation with the fridge standing upright, which was quite the challenge!

    Once everything was connected properly I set the thermostat to around 2-3.
    It seemed to have fixed the problem but I didn't want to celebrate too soon. I waited a week or so before I was confident there was no more freezing. The food was still quite cold so that's why I wasn't sure at first.
    So now that everything is working properly again I really don't know if the new thermostat was necessary or not. It's quite possible that had I done the same operation with my existing thermostat it also would have fixed the problem.
    I am keeping the old one just in case and am thinking of actually buying another new one as a backup.
    I was surprised to be able to buy this new one. But it said it works on many Dometic models so it wasn't my model specifically.

    In the 26 years that I have been using my fridge (which I love) I have learned there are only two critical components; the cooling unit and the thermostat.
    Do you think I should buy another backup thermostat while I still can?
