Intermittent Thermostat Trouble

My 2016 Elkridge Xtreme Light 5th wheel has dual air conditioners with one thermostat in the living room and another in the bedroom.

The one in the living room has an intermittent issue where it looses power when you push on the buttons; kinda like a loose wire. It's a pain when you're trying to adjust the temperature and it "turns off" for a second before coming back on set to the old temperature.

I've taken the cover off and the wiring isn't loose. I figure it's just a loose connection on the circuit board.

I figure at this point I should just replace it, but I haven't been able to find what I need to order. It's the simple black square Dometic thermostats for heat and air only; no bluetooth or anything fancy.

Any help would be appreciated.

Thanks!

Check out the communication cable at the ac unit. Looks like a phone connection. Maybe try a bit of dielectric grease inside both connections.
