Dometic fridge constant alarm

[FL_Matt]

Dometic DM2672RBX dual door.

When I turn on the fridge on AC or gas the interior light comes on for 1 sec. Then the interior light goes out and the check alarm blares constant. Occasionally you will hear a click and it will stop for a few seconds, then it will do it again. the alarm has no pattern; it is random and can go for hours without stopping or go on and off like a toddler with a Hess truck. The fridge is cooling, and the freezer has a light film of frost. LP is good, fuses are good. Do I need a new control board or cooling unit?

Best thing that happened to me was when my Dometic failed a few years ago. Was probably just a fan but that was the excuse to pull the Dometic and replace it with an 18 cf Samsung residential. Installed a 1,000 watt separate inverter with a built in transfer. Refer is never without power and the extra space is great.
