Dometic issues

We have a 2012 cedar creek 5th wheel with 2 ac installed. We bought it used in 2017 and been parked at our lease since. Has 30amp power so we keep the front ac off using the breaker. We have been having issues with the ac since, dometic cc2 will show e1 error and have wide fluctuations in tempature for inside, ac would work for a bit then slowly trip the breaker. Does anyone know where the internal temperature sensor is? I located the 2nd one in the master bedroom, dont think that one reads the cabin temperature.

I think it is probably in the digital thermometer itself...I know when I leave my door open to long it tends to cycle on pretty quickly. My t-stat is right as you come in the door..

It is right by the door but my brother in law has a digital thermostat close by and it doesnt read nearly the same. Maybe its time to replace it

My experience is that the thermostats are not very accurate ( calibrated). I find a setting that we are comfortable with and set it there. Once you get a number that works, it keeps it fairly constant +/- 2F even if the reading is not correct.
