Both Dometics short-cycling

I have a 2014 Flying Cloud 27FB with two Dometic heat pumps. My problem is, each will run as long as needed to reach the set temperature, then they will begin short-cycling. That is, each unit will run for 1 or 2 minutes, then shut off for 1 or 2 minutes, then start again, etc. This happens when the units are in heat mode and also in A/C mode. It happens when both units are being used (when I have 50-amp power) or when either one is being used individually (30-amp power). I've cleaned the filters in the ceiling units - no effect. I'm thinking it's the thermostat. Any thoughts/comments on this will be appreciated!
