    I found a mud wasp nest on the rear of the fan prior to your response, vibration is gone(oh suprise!!) As far as unit turning on and off continuosly,the entire unit shuts down and comes right back on several times but not all the time. It will run for a while normally and then starts to go on and off. I found the nest when I was on cape cod just before I left for home so I do not know if the on/off situation still exists. Is it possible that the excessive vibration caused the unit to act that way?? I will try to run it off my home power for a while and see what happens. My only concern is that I only have 10 and 20 amp circuit breakers on my power board in the house. Are they sufficient to run the unit without causing damage??

The 20 amp will be sufficient, you'll just need an adapter to match to your plug.

    I ran the unit for an hour or so and it did not go on and off as before. Probably fine until I take it back to the cape in a few weeks. Thanks for the input

When i turn on the ac the transformer fuse will blow

If you are blowing a fuse just when you turn on the ac then the anomaly has to be with a circuit that only operates when AC is turned on. How about the compressor clutch which is electrically operated? If hot wires going to that unit lose insulation and get grounded, then the moment you turn on the Ac you will have a short and the fuse will blow. Or maybe the clutch has developed an internal short.

Dometic ac model # 57915.741 Ac is vibrating bad when on.

Hopefully there is just something in the blower wheel. Unless you can get to it from the ceiling of the RV you will have to take the cover off the unit to get to the blower assembly. The blower is the front fan that blows the air in to the trailer. If you can get the grilles off of the ceiling, turn the unit off and use a flash light to see if there is something stuff up in the actual blower or the assembly.

I have my dometic Rooftop ac unit. The heatstrip/fan run perfectly but when I turn on the ac...the fan runs good but when the compressor kicks on it just hums.

The compressor coming on does make a slight "humming" sound which is normal. Is the unit cooling properly? Do you think it is louder than before?

I have a dometic roof mounted air conditioner 3300 series and it developes this vibration like a real loud hum

sounds as if the fan motor bearing have worn out lettin the fan cage wobble upon reaching full speed hence the vibration. There also could be build up of debris in the fan assembly. Good luck on your repairs

RV ac is vibrating

Take a good look at fan blade for a crack in one or more, as well as turn unit on & watch for vibration , then take a look at mount bushings on all items. Also with fan off (obviously) check shaft for movement, side to side, up & down, in & out. Your gasket between roof should only be compressed approx half it's original thickness. Some manufacturers tighten them down too much and can be a source of vibration as well. Not expensive or hard to change. Don't forget blower wheel as well.

Relay (?) sticking Dometic RV rooftop AC

Go up on the roof of the unit and remove the AC Shroud. With the unit running, see if you can pinpoint where the sound is coming from. The only thing on the entire AC that would make that much of a vibration would be the fan motor. Not sure what would cause the fan motor to do this. The compressor may do that but only if the windings are bad and then it would not be cooling.

Dometic A/C Vibration

sounds like the fan bearings are on the way out , these units are designed to be removed to be opened and usually they op from the part that touches the roof of the car not the top so remove it first might be a start
