Fridge not cooling correctly?

Fridge worked fine before storing for the winter but now it's not cooling correctly. A few years back I had problems with it freezing up so I did the snip-the-tip.com trick and removed the thermistor and replaced it with an adjustable thermostat. Now if I turn this adjustable thermostat to the coldest setting everything seems to work correctly but the temp inside the fridge doesn't match the temp. setting on the thermostat. What I'm wondering is, should I go ahead and replace this thermostat or is there something else I should be looking into to that could cause said cooking issue? TIA
  • Check,clean.
    Check for yellow stains on the cooling tubes.
    Clean the burner and chimney.
  • If all else fails, buy a compressor fridge and live happily (and colder) ever after.
  • Is the fridge mounted in a slide? If that is the case, it cannot have a rooftop vent and will rely on a couple fans to help move air through the two sidewall vents. The little sensor that controls the fans are notorious for failing.
  • Do the dollar bill test on the seals. I had to add some weather striping to mine (too old to get door parts).

    Also, I found that the condensate drain was allowing warm air for the hot box back into the fridge. I plugged the drain and things got better.

    Amazing, how the Door Seals and even the Drain affect what I'll call the "fragile" cooling produced by RV fridges. Have also read that the condensate drain should have a little bend in it to form a "trap" where a little water prevents air flow. Haven't tinkered with that...

    I've experienced gasket leakage, and was ready to replace the fridge before investigating gaskets. We have a NorCold, and the gaskets aren't worn out or damaged, but still nearly 15 years old. I tried springing the doors so the corners opposite the hinges touched first. This was supposed to allow contact all the way down the door edges because the latches would hold those second-to-touch corners tight like the first ones.

    Wrong! Doors aren't stiff enough to hold that twist. Now we knee the bottom of the fridge door and high five the top of the freezer door as they latch. Fridge is now performing OK.
  • Not to steal the thread, but what kind of small fan do you install outside to help with cooling?

    This Fan installs behind the frig to keep air moving

    Had this same issue on my 22 year old Norcold, I ended up removing the black plastic door latch and grinding about .050 off the back of it effectively removing the gap between the seal and door flange allowing a tight seal again.
