Information Needed for Refrigerator Decision
I am having problems with my Dometic refrigerator. It is great at keeping everything cold and frozen, but there is frost build up in the refrigerator and freezer. In the refrigerator, the fins frost u...

I also have a 1402, that I've been struggling with for a while.
Mine frosts up in both the freezer and the fridge, worse in the freezer.
And it heats up excessively while travelling.
Just FYI's...
The 1402 has 4 thermisters, one on the freezer fins, one in the freezer, one on the fridge fins one in the fridge. They are not adjustable.
The led display shows "an imagination" of the temp of food in the fridge and the freezer. We can see when it is warming up. Normal is 1-3 degrees in the freezer, 32 to 34 in the fridge.
It controls the temp in each box separately. The freezer temp is controlled by how often and long the cooling unit is heated. The fridge is then warmed with the defrost heater to hold it's correct temp, supposedly it would otherwise run too cold.
The 1402 has a factory fan in the fridge, located at the top rear.
And one in the freezer, in a complicated ductwork intended to fully circulate the air top to bottom and force feed it thru the freezer's cooling fins, which are mostly sealed and invisible.
The fans are controlled by the door switches, only run when the doors are closed.
It has a diagnostic test mode. Detailed in the book. Hold down set then turn it on for diagnostic mode. Press set to step thru the various tests. All in the book. You can check the door switches, turn on the AC or gas, turn on any of the 3 defrost heaters, etc. You can test everything.
It has a clock. That needs to be set, once unless power is removed for a long period of time. it flashes -- -- if the clock needs to be set.
It defrosts every night at midnight. A complicated process, with the bottom line that it has a set amount of time to complete, and it heats the cooling fins to 40 degrees for a set period of time. Supposedly it will show an error if it is unable to get the fins to 40 degrees in the proper amount of time 2 nights in a row.
Mine has never showed this error, tho it doesn't appear to successfully defrost.
I have a real love/hate relationship with this thing.
It is WAY more complicated than your typical absorption fridge. I WISH i could control the temp by sliding a thermister up the fins, and defrost it with a hair dryer once a month...
