Dometic NDA 1402 Victory!!!
I've posted about this fridge more than once, first how to fix it, then what to replace it with.
This is a killer RV fridge. 14.5 cubic feet. Ice maker, and ive and water thru the door. The side by side Z-doors give some extra width for big stuff, and look "cool." Being able to run on propane is a big plus as we love to boondock.
It's also the only RV fridge with true auto-defrost.
And it's been making me nutso all year not wanted to cool good, especially the freezer.
Well Friday it finally seemed to have given up. After a short drive Thursday, it never recovered, freezer was in the 20's, fridge near 40.
I'd been eyeballing an ice buildup, and seeing it creep halfway across the fridge coils, it was time to get out the hair dryer.
I took everything out of the middle of the fridge, put a towel in, and made quick work of the ice on that side.
The freezer, I had to pull the ice dispenser tray, then the ice maker. Then the "cooling tray" that the ice maker and ice bin sit on. And finally the cooling coil cover on the right side of the freezer.
The fins/cooling unit under that cover were iced solid!
This thing is supposed to suck warmer air from the bottom to a fan, then blow it up, and across a manifold and down thru the cooling fins. Which were iced solid.
It took a couple hours with a 1500 watt hair dryer on high to melt all that ice.
When I put it all together and closed the door, I was at 29 degrees in the freezer, 49 in the fridge.
Next morning, 11 / 36. 12 hours later 5 / 33. and 2/33 the next morning.
After 3 days steady there, a 2 hour drive. Temp was solid as a rock.
I've been paying attention to the ice on the fridge coils, by evening there is a light coat on half, in the morning (after the defrost cycle) they are clean again.
So far, no buildup I can see in the freezer.
Gonna continue to watch it. I'm not getting any error codes, and all the service mode tests check out, so I'm hoping that with a once in a while manual defrost, I am good to go.
This thing was the peak of amonia fridge technology, best they ever made (supposedly) and I'm really hoping to keep it.
