2022 Berkshire XL 40-D--A/C Temp sensor for front and Kitchen not working

The compressor for both the Living Room and Kitchen A/C are not coming on. The rear bedroom A/C does come on. The Precision Circuits board says "No Temp Sensor" for these two A/C units. The temp Sensor for the kitchen and living room is just below the main circuit board. Also, the 12 volt light switches for the kitchen and living room below the main board are not working. But, other switches for these lights (at the main entrance and next to the sofa) do work. Any suggestions?

AC disjunction

Did these things ever work?
What happens when you run the diagnostic program?

Yes, all the A/C's and the light switches were working until this past weekend (Sat July 2, 2022). I did run a diagnostic check and it showed no problems. It appears the two 12 volt sensors (temp sensor & light switches) next to the main Precision Circuits board are not communicating with the system. Earlier today I sent an e-mail to Danny DiNova with Precision Circuits and copied Berryland Motors, my dealership, and Mitch Wirt with Forest River Diesel Division.

RJ12 connector

I had the same problem last year. A RJ12 splice connector had caught on fire. It was located under and behind the entertainment center on the left side of the kitchen. The power and data cord (RJ12) looks like a telephone cable. The splice is a tan rectangular box with female cable plugs on the ends.

Your most likely cause is a loose/disconnected data wire that goes between the bathroom switch & the switch by the Touchscreen. It's super easy to access by unscrewing the bath switch.
