Dometic Fridge not cold

[L D Hobbs]

I have a RM 3862 fridge worked fine last time out 4 months ago .Now it would cool the box a little bit but the freezer only the bottom would get cold. it was plugged in on electric and Saturday morning it was working fine.Tonite I checked it and it quit again.It does not make any difference if it's on gas or electric

Questions?

How old is the fridge ? Is the RV close to level?
Have you had the outside vent cover off and checked for any yellowish powder around the cooling unit ?
If there is any sign of the powder ; shut the fridge off ! it's a fire hazard.

If there is no sign of the powder, there may be an internal blockage in the cooling unit , this is caused by crystallization of the fluid in the unit , sometimes leaving the fridge on the highest setting will dissolve the crystals , other times driving the RV around will move the crystals to where they can be dissolved, other times , removal of the fridge and shaking and rolling is required .
Worst case is replacement of the cooling unit , or the whole fridge.

I figure it must be a blockage. Taking it out this weekend so I will crank it up and hope for the best.
Worst case will be a new cooling unit .thanks for the help ,��
