AC fan cycling

I have a 2014 FR3 and have a new problem, when running the AC with fan on low or auto the fan will shut off briefly even though I hear the compressor still running. If the fan is on high it doesn't cut out. Ideas? Ambient was in the upper 70s and not very humid. It did drop some water inside yesterday for the first time too, not sure if related or not.
Thanks in advance

I had the same issue this weekend in our Wildwood TT. Anyone know what is going on?

My 15K Dometic on Automatic will do that back and forth. It adjusts fan speed to the desired output.

That's the way it's designed to operate.

When running on high and the temp is getting close to set point the fan will shut off for a few seconds and restart on low. By the same token when running on low and the temp starts drifting further from set point the fan shuts down for a few seconds and restarts on high. When either scenario happens the compressor continues to run.

If you have a ducted system, many times there is insufficient air flow over the coils to keep them from freezing. It can be caused by several issues, but most often it is the lack of air low. When first running the A/C after setting up camp, open the "quick cool dump" ( louver on the ceiling unit) and allow the camper to cool ( dehumidify) for a while then you can slowly close it to have cool air sent to other parts of the unit. This should resolve your issue.

I had this issue on the last night of our trip. I didn't know what was happening. It didn't seem to affect the way it was cooling. Glad to see its normal.

I read somewhere, can't remember where but if on auto the fan will run on high til temperature is four degrees from tstat set temperature. Then the tstat will adjust fan to low

Just joining in that my front unit has been stopping and restarting, but at the same high speed. In fact, I've only used auto but never heard it on low! I'm going to give the quick cool idea s shot and see what happens.
