Well, I ordered a new Control Board for my old Dometic RM3862 frig and when I installed it, the 110 still did not seem to work. I got this really stupid idea that maybe the house current was not good enough, so I unplugged the line to my 110 V 15 amp breaker and connected it to a 110V 20 amp breaker and a heavier line. I plugged the frig in and smoke came out of the board! I then tried the old board and the same thing!
I cannot believe I fried them! Now I have ordered a new one, but need to check things before I put it in. I want to confirm the voltage and that I am connection the correct wires.

Did you plug the whole RV in ? Yes
Or just the fridge 120 volt plug to the outside source ? No the whole RV
15 amp or 20 amp 120 supply should not have done this ! 15 amp nothing was happening, the voltage was 117, so I went to the 20 amp 117 v line
I'd be testing the voltage at the outlet first . Then making sure it's wired correctly if it shows 120 volts ; possible hot neutral .
Have you done a resistance check on the fridge 120 volt heating element? I just replaced the heating element.
