Is rv (fridge) level? Needs to be level for proper cooling.....off level causes permanent damage!
Have you check for any obstructions in outside compartment------cooling air flow must be free/clear from lower vent up/across backside of fridge to upper vent?
Have to have good draft!
Third.....thermistor
Is it still attached to far right fin in food section?
Thermistor controls 'auto thermostat'-----bad thermistor/bad cooling
Thermistor can be tested by unplugging from lower board, placing tip in glass of ice/water (more ice than water) and then checking resistance at leads.......8000/10000 ohms

LINKAnd then there is the fact that cooling unit could be plugging, has blockage.
Unplug thermistor from lower board
Turn fridge ON (AC)
Check temps after 12 hrs
Then check again after 24 hrs
Then again after 48 hrs
With thermistor unplugged fridge will run continuously and food section should freeze. IF temps fluctuate then cooling unit is bad.
Is it time for your medication or mine?
