Refrigerator does not maintain cool temperature well

[snsjets]

Unit is 13 years old and has had no problems. Until this last week the temperature setting was always at #3. Now it has to be set to #4 or higher(cooler) to keep food at a comfortable temp - below 40 degrees. The coils have been thoroughly cleaned and there are no unusual noises. The frige is not running any more than usual so it doesn't appear to be overworked. Possibly a bad temperature sensor?

Is it maintaining 0 degrees in the freezer?

I just checked the freezer. Items are still frozen but it is slightly warmer than usual - ice cubes are glossy and ice cream is a little soft. Thanks.

Unless you have calibrated eyeballs, you did not answer my question

The freezer is maintaining -2 right now. I'm not sure what the freezer temp was before since I didn't keep the gauge in there.

Ok, so we know the freezer is normal, actually 2 degrees too cold, yet you have warmer temps in the fresh food side than normal.  The next step would be to inspect the defrost and the damper systems on the fridge. If too much frost builds up on the freezer coils it can hamper the airflow to the other side. Alternatively, if the fan in the freezer canno move the air thru to the other side effectively, there will be an increase in temp on the FF side.

The point being made here is that if the freezer section has normal temps, so should the FF side.

OK. How do I inspect the defrost and damper sytem on the frige?

I would also check your fan motor

I am glad you mentioned the air diffuser assembly. It was blocked! Now that it's not everything seems to be working normal. Thanks folks.
