I have a Bosch refrigerator Model #b20cs8sn/02. The problem I am having is that the thing will intermittently stop cooling in the FF section and if I unplug it for a few minutes and turn it back on, the thing works great. I checked all the usual stuff, evap, dampers, thermistor, t stats, ECT. I have a good frost pattern and freezer works real good. I am at my wits end on this one. Thank you for any info.
