Is it a Multi-Temp unit?
Have they checked the temp sensor and its wiring harness in the trailer?
Sounds to me that this sensor which sends a temp reading to the computer which instructs the engine/compressor to heat or cool is bad. Depending on age of unit it may have worn away the insulation on a wire and it shorted out. Especially since it is hanging @ 40* it tells me that the sensor is sending a set signal and it is bad.
