Era 70a air conditioner

[Orlan]

We bought a used 2015 Era and generally love it, but the AC keeps freezing up. The dealer says this is normal and it mus be shut down periodically to thaw. In south Texas this is problematic. Does anyone have similar experience on this?

Sounds like the evaporator is not working correctly. It may need cleaning. You might want to review the following link.

While it is general in nature, it provides some helpful information.

Take your unit to an actual AC service center to have it looked at and the service valves installed. I am a former AC mechanic and installing the valves is an easy 1 hour process that will make the unit serviceable in the future. Dometic is intentionally not installing those valves because it is more profitable to sell a new unit. Some of it might be EPA rules as well. Notice how new refrigerators aren't serviceable either? Back a few years ago, they were serviceable. The freons are available and these units are serviceable once the $10 valves are installed.

The refrigerator is an important part of your RV, containing everything you'll eat. Keeping the refrigerator working will make your trip go a lot smoother.

Agreed on having service valves installed. Any RV place will tell you that the unit is sealed and can not be serviced. This is pure B.S.! By having service valves {Shrader valves} installed one can check the refrigerant charge, add refrigerant, or even evacuate the system for a full charge. The installation of the Shrader valves and a full charge of refrigerant was done on our system for $150. A new system per the RV Dealer would be $1500+. Now you figure out which is the better way.

And one should check evaporator and condenser coils for the build-up of dirt, leaves, and any other debris. Also, change the filter on the inside just as you do at home. This protects the evaporator from dirt build-up.

Typically freeze-up is due to a low refrigerant charge, or restricted airflow.
