Norcold Refrigerator not cooling

Fan is thermostatic controlled ----senses Condenser FIN temp (finned section at top of fridge)
That is where hot ammonia vapor is condensed into cool liquid ammonia.
Thermostat turns fan on at 135*F FIN Temp and off at 115*F FIN Temp

FINs only get hot when vapor is being generated/flowing thru cooling unit

IF Fins are HOT (indicates flow) then FAN NEEDS to be running.....if NOT cooling WILL be affected.
Bad thermostat/bad fan/blown fuse on DC to fan (DC to/thru t-stat then to fan)

FAN could be powered via separate DC line with 1A in-line fuse
FAN could be powered directly thru circuit board.

IF fridge is in a slideout......FAN Required
T-stat on FIN can be accessed via upper side wall vent/cover

Not in a slide out........harder to gain access

If it has one of those little disc thermostats then it's probably blown. The one that came with my Norcold lasted one weekend. The next one held up longer but I replaced it with something better.

Thanks, the fridge is in a slide out, will work on getting the fan to work.

old biscuit, glad you are still around! So many, the old timers like us either not here anymore or not here on earth. Glad to see you are still around.

Old-Biscuit is an expert in this field! I wondered what Norcold, I had issues with the 18 CUFT he helped me with. I also found a repair on the doors that did not close as it was supposed to.

THANKS!

End of 2019 and 1st two months of 2020 were NOT pleasant to say the least.
Emergency bowel surgery....twice. 25 days in hospital being fed intravenously NOT recommended.

Finally got good enough to come home so doing MUCH better.
Still have 6 more weeks of 'healing' then get to go back to have 'innards' reconnected.

I don't post much any more but am still around.

OP....
Via upper side wall you should be able to access that fan t-stat.
Jumper it out and check if fan runs.

Good to hear you're doing better.
As always. I'm going to take your recommendation and try to avoid that scenario. ;)

Update: Tested the fan, tested ok, also tested the thermo disc and it check out ok, still not cooling, any suggestions what to look for.

Does cooling unit/condenser fins get hot?

You can 'force' cool to test if cooling unit will function'
Unplug electric heat element leads from circuit board and wire them directly into 120VAC Outlet....this will energize the element continuously force cooling of fridge
Freezer should get down to 10*F (lower) and food compartment 38*F (lower) IF cooling unit can flow ammonia (vapor to liquid to supercold vapor to warm ammonia and repeat cycle)

Let it operated 12HRS at least before checking temps.

The condenser has heat however not getting hot enough to activate the thermo disk for the fan to run. Everything else appears to working as normal. My guess is that the ammonia may have a slow leak. What are my options, replace or repair. The refer is 11 years old. And thanks Old-Biscuit you been a big help.
