I have a Norcold 120X-IMXX unit. It is a 4-door unti. The freezer temp is approx -10. Since defrosting the temp in the refridge part does not run as cool as before. The weather has been warm but normally we run the temp at 7 (scale 1-9). Now we must run at 9 just to keep the temp at 40 or so.
Is there any adjustment that can be made to deliver more cooling to the fridge?
On the cooling fins in the frig. there is a small clip withe a wire on it. this is called a thermaster and it you move it up or down or to thr next fin it will change the temp. of your frig. On mine I pulled it off and discovered a small amount of carotion on the fin. after cleaning it I re installed it at the bottom of the same fin and returned my setting to 6 and it ran at 15 degrees in the freezer and 40 in the frig. I set it on 7 and it ran 8 in the freezer and 36 in the frig. Just another idea. GOOD LUCK
