Dometic Z-Door (ndr-1402) cooling issues
Our 08 Monaco has one of those z door refrigerators. Up until this year, it has always worked great.
I need to do more troubleshooting, with the delay in these things cooling sometimes it is hard to tell, but it appears:
It doesn't cool when we are moving.
It also doesn't work well when we are parking (24-36 hours plus...) on an asphalt parking lot.
It doesn't seem to matter gas or electric, if we are on the road, or parked in the lot behind my office, it gets warm.
When we got to this campground yesterday afternoon, the freezer was at 13 degrees, fridge at 43!
By the time we woke up this morning, the freezer was down to 5, fridge 39.
And now, freezer at 0, fridge at 33. 86 degrees today, bright sun, no shade awnings open. on grass.
On the road it makes no difference, warms up with genny on or not.
No error codes ever.
I've run the diagnostics, everything passes.
Defrost heaters work.
Lights work. Factory inside fans run with doors closed, stop when open.
Door gasket heaters work. Gaskets at least appear to be good, and hold a dollar bill, tho I wish a bit tighter.
Fridge is in a slide.
Monaco seems to have done a good job of it. The top of the fridge and above the top vent is insulated and sealed. The sides are well insulated, visible from behind. The back has a large baffle between the outside wall and the coils, to force the air past the coils.
There are a pair of fans installed behind, controlled by a thermister on the upper coil. I used to hear it cycle on and off. Haven't for a while, replaced it with a switch, running the fans continuous, no change...
What have I missed?
What else is there?
Is there anything inside the chimney that would effect both gas and electric?
Could the baffle have moved or fallen?
How do I access it?
Is there any maintenance / cleaning that might help?
