The compressor run but no fan high or low
SOURCE: Duo Therm compressor tries to start and kicks out
I don't think these little units have a start capacitor but what I would do is check that the on/off switch wires to make sure they aren't loose. Also check the wires to the compressor for loose wires as well. It is possible that these are the first signs that the compressor is about to fail. They also can act up some when they haven't been used for awhile and then you try and start them up. Try running the unit for a few hours without asking it to cycle. It might just be a sticky valve.

SOURCE: duo therm air conditioner that the compressor will not start
your switch should be oopen but when it reaches 41 degrees it should open so the system shuts off before it damages the compresor by sludging it, i have the same unit and my compresor runs for 5 seconds and shuts off, i checked the amp draw at the compresor and it draws 21 22 amps trying to start after the initial 5 second run, but it wont come on againts a load so the comprresos equilizes and tries to start over again with out positive results. i bipass the external obverload on top of compresor terminals area, still no fix yet, the relay on the control board continious to send power to the compresor and still draws , so if there is a problem with the control relay i would open up and dont send power to the compresor so i dont think is the relay, i am a a/c service man for
35 years and do this for a living still today, by experience i think it is the compresor gone bad but will try by passing the relay just to see what happens, also it could be bad capacitor since it have a hard start relay and start capacitor (black )also a run (silver ) capacitor they check ok, there is no way to check the charge unles you install a saddle tap to check presures and rechage this unit i think the compresor replacement is the way to go ( around 250) plus labor and freon r22 e mail add [email protected].

Inspect all electrical wires and connections and correct any areas that appear damaged or overheated or loose (connections). There is a capacitor which is a round or oval component in series with the contactor and the compressor. Thoroughly mark all connections and remove the component. Take it to you local RV air conditioning repair shop and have them test it. If it is faulty, they will provide you with a replacement part. If it is not faulty and all wiring is okay, your compressor is locked up and will need to be serviced by a professional air conditioning technician.
Try the wires and the capacitor first.
I hope you find this information to be very helpful to you as a good, solid jumping off point moving forward.
