AC issue

[Caroljean]

We have 2018 Apex with Dometic air conditioner. We've had extremely hot summers the past year and have noticed the ac will run for awhile, stop and 5 seconds later restart. Might happen 3-4 times in 10 minutes then run normal for several hours. We tried it in auto mode and low/high mode and same issue. Any ideas why?

Sounds like it's switching fan speeds, but doing it that often isn't normal.

Have you checked the return/supply partition to make sure it's sealed up? That could cause it to short cycle.

You should also try to initialize the thermostat.
