Norcold 1210 quit cooling

[09FLSTC]

Not a problem for 8 years since 2007. Just quit. Green LED light is on. Flashes AU--AC when you press the mode button which means automatic mode, AC available but doesn't switch to AC solid and come on. Burner does not light. Then......switch manually to LP and the flames lights, stays lit all night but no cooling.
Before, when I selected the mode button, it would start searching for AC and if not available, would switch to LP. Does not even try to do that now unless I switch it.
I have the service manual but don't have my multi meter with me, arrr.
Any similar out there?
In Edit, recall mod has be done.

Turned out to be a rupture in the cooling unit. Never did smell ammonia and couldn't see the evidence at first but its there. We were gone when it quit so might have if we were there. Regardless, this ain't a cheap fix. Thankfully extended warranty (that I rarely buy) is taking care of it less 50 bucks deductible. In case you were wondering, $2400 with labor. I'm sure it can be done for a lot less but I don't care what they get as long as my warranty company is willing to pay.

Is it inn a slide? If so, the fans may have quit. Ours was just corroded contacts to the fan. (Thanks Doug Rainer)

Batteries are fine. Plenty of DC. I'm not feeling too good about the controls or the burner but hoping for the best. Thankfully, we have an outdoor fridge where we're at to get it accurately diagnosed.

How's the charge on the battery? It is needed for proper operation.

First remove the outside inspection cover and look for greenish goo and/or smell of ammonia. If you see greenish goo and/or smell ammonia, immediately unplug the fridge and DO NOT USE. Fire risk.

If that's clear then try the steps below.

Try shutting the fridge OFF completely and then turning it back on. If that doesn't work, unplug the fridge completely and let set for 3 minutes, then plug it back in. Finally, make sure your batteries are fully charged. The fridge needs 12V power to turn it on....there's other tests if this doesn't work....Dennis
