When your 'sensing unit', called a thermister
goes bad, it depends on how it failed. If it failed in the open position, it will cause the board that operates the cooling unit to run wide open, this creating a potential freezing situation in your fridge section.
If it fails in the closed position, it will do the reverse and essentially turn off the unit causing it to warm up.
The thermister changes it's resistance relative to the internal temp of the fridge and sends that resistance value to the control board, which then either runs the heating section of the cooling unit or shuts it down. There are ways to test your thermister at varying temperatures. Check with your operations manual for details, call the fridge manufacturer tech support line or find a qualified RV tech who is well versed on this subject to do the test.
