We're having the same issue and the frequent short fan starts and stops is not only annoying, it's aggravating as it might be a sign that something is wrong.
The downside of running in the "Low" setting the is that the fan NEVER shuts off - which makes it about impossible to watch TV, have a conversation without shouting, or even hold a thought in your head.
We have a marine A/C unit in a boat, and it regularly turns on the fan for a few seconds to "sniff" the air temperature to see if it needs to turn on the compressor. That is annoying. The situation in the Ollie is worse.
I doubt this condition is a power issue, as on initial start-up, the fan always starts and then the compressor kicks in. If it were a power issue (IMHO) the unit would certainly falter at that time.
Frankly, I think this is a bad programming job by the Dometic engineering people than can and needs to be fixed. Once they do that, then maybe they can reduce the noise level to something less than running a Harley in your camper...
