Re: Norcold refrfegerator 1210 not cooling
trholthus,
Next time this happens, before you cycle the unit, run (or check) your diagnostics and compare with the user manual -- typically, if there's a fault in there...that's where it will show up. If its an ammonia clog, it won't show and you're just going to have to power it down for a while until it shakes loose. At least, that's what I've had to do in my experience.
The Diagnostic Screens where my faults show up have been on Screens 4, 5 and 8 -- you can often find someone to help walk you through the next step or two if you can clearly identify the fault, so try that. After you've cycled it (off and on), the diagnostic fault will go away. I'm having a similar case right now that I can't replicate, but I know what the fault is when it happens.
Make sure you can report the fin temp on the Diagnostic Screen and an internal thermometer temp to see the differential. Dan makes a good point about the freezer as well. Oftentimes you'll get very different readings on the bottom of the left freezer compared to the top part of the right. My fin temp is the only common indicator I have to go on most times.
Finally, do keep track of the defrost cycle timing. I've come home to find my temp showing going up, only to remember (after a slight period of panic) that its probably in the defrost cycle. I'm chalking it up to a sign of age (not the fridge, my own)!
I wish you luck!
