We have a Dutchmen Kodak 291RESL 2017.
Thermostat is a Dometic Capacitive Touch 3316410.
On our maiden shake down cruise, found the AC won't shut off. Our thermostat is black with blue lit background. Seeing the inside temperature was at 86 degrees when we got hooked up at campsite, outside temp was 82, I set thermostat at 78. After running for 6 hrs straight, inside temp is 76 but it won't shut off! Doesn't matter what setting is, it runs if it's in the Auto mode.
I raised the thermostat in 1 degree increments for a few minutes each until it was at 90 and it keeps running. The fan runs constantly and you can hear the compressor kicking in for a few minutes and going off, over and over.
Can't get it to run on low fan speed either. Manual says it will run on high if there is a 5 degree or greater difference, then supposed to run on low once 4 degrees or lesser than thermostat setting. Ours just runs on high continuously.
Once when poking some buttons, the heater actually came on simultaneously as the AC! Both were running! Not just the fan on the AC but compressor was running too!
