The E4 error code you are getting on your Atwood Air Command Rooftop RV Air Conditioner # AT15027-22 does mean there is a lack of refrigerant, the compressor is not running, or the thermistor is out of calibration, as you can see in the cut out I added of a guide for this AC unit.
These units are absolutely serviceable, and it is strongly recommended you use a qualified technician as it can be a difficult process.

I had one of these these air conditioners come in today. Customers complaint displays E4 code after 10 minutes of runtime.First thing I always do pull the filter. It was completely packed full of dirt. Test ran the unit for six hours no issues. So it’s possible that a clogged filter can cause an E4 code.
