Hi all!

We have a 2019 Retro 285FK with the Dometic air conditioner and digital thermostat. What we have noticed with our limited use of it, is that when the A/C reaches its cutoff temperature (let's say 72F), it shuts down, as it should. But then, within ten seconds (as opposed to the two minutes it states in the manual), it restarts again. (BTW, this thing always runs at full blast (LOUD!) too).  I don't mind that it decides to restart, but I'm afraid that the A/C's Freon pump may become damaged by this rapid restart rate.

How long should it take for the Dometic to restart?

Thank you!

I believe it is kicking down to low fan

We bought a 2017 199FKS a year ago and lived in it through the summer while our house was being built. We noticed our unit did also did this, most often on very hot/humid days. One thing we thought might cause it is that we had clothes hanging in front of the thermostat and might be reducing the air flow around the thermostat. We never did really figure it out but I remember that we also would raise the temperature setting and that seemed to help. Our unit ran great all summer so I don't think it hurt the unit. I know this probably does't help you much but at least you know others have experienced it. We used small clamp-on fans in a couple of places and that really helped on the hot days. We also ran a dehumidifier all the time. Good luck!!

Thanks zendafus, that does help!  I noticed that it only occurs on a hot day now too.  Since a functioning thermostat is a relatively new thing in both cars, trucks, and trailers anyway, I have decided to, as a just-in-case measure, use the A/C thermostat as a simple on/off switch (or we can use your technique of thermostat setting, which seemed to work for us too when I tried it a few minutes ago).  Also, as SNOS1 stated, maybe the Dometic is just kicking into low fan and I just don't notice the difference in fan speed due to the ten seconds of A/C off cycle.
