A/C control box

Any idea where the A/C control board is located in a 2015 3625RE? Not the thermostat. Have two a/c, the one in the bedroom is turning on and off too much. It gets to temp then shuts down for several minutes to then start back for a few more minutes. Doing all this with no change in room temp. A few times the fan has got stuck on constantly. I have read on Dometics site that there should be a individual control box for each a/c. Canít find it in my unit. Havenít taken the underbelly off yet. Thanks

I'm thinking the control board in the unit on the roof?
Depending on which version Dometic air conditioner you have, I believe there is also a thermostat sensor in (inside) the wall or in the return air duct work?

Thanks, See the thermostat in the bedroom, it’s in the corner of the room.

Put some tape over the sensor .. Run it and see what happens. Mine did the same thing. Short cycled. Tape worked. Control boards are on each unit above the cover.

In the files section there is a Dometic AC Drip pan leak TSB. It shows how to access the control board in the rooftop unit.

Where would that sensor likely be located?

Typically somewhere on the ceiling in the bedroom. Could be on the wall. My AC was blowing cold air right on to it an the AC compressor would shut off.
