I am thinking it is the thermostat. I am not sure how to test that part or where to source a new one.
Any ideas? I have been having fun troubleshooting today. I think I am close to the answer.
If you're talking about the 'thermister', which is the little device clipped on to the right most fin in the fridge section, there is a definitive test to determine if it is operating properly.
It involves removing the t/mister from the unit and taking an ohm reading at room temperature. You them soak it in a glass of ice water for about 10 minutes and take another reading.
Dometic has tables listing the required values that you should see for t/misters from the various fridge models.
The other way is to disconnect the t/mister from the control board (the plug position is shown on the schematic pasted to the back of the fridge). This will allow the fridge to run wide open with no temperature control. If the fridge doesn't get to almost freezing, then you have other issues.
