I think they are all dometic, either 13.5 k btu or 15k btu, depending on where in the rig unit is located. Unless you are electric savvy, as well as understand how these work...you will be wiser to have a good mobile tech come do the fix. If you are attempting this yourself...power off, and if the unit is one that has an inside cover, then you have to remove the cover to see the approximately 5 by 7 box that has the circuitry to control the air conditioner. If nothing looks amiss so far, then you will need to remove a cover on this to expose the hot, neutral, and ground for 120 vac. If all are connected there, then it is roof side, remove cover, remove metal cover inside to get to the power connections there. You can fry your unit if you do something wrong. There is also a large capacitor in there that can kill you or cause you to fall off the roof if you get in contact with it. This is why you should contact a tech. John
