Hello. I have been fighting a refrigerator side cooling problem for several weeks, and have read many many posts on this forum about this issue, so thanks to all who have contributed to the forum. I have replaced the main control board, did not help. Confirmed the FC and RC thermistors seem to be working (ice bath test for RC thermistor, self test for both from front panel, and ohm out from rear of fridge at connector J5 for both). Self test #4 passes. The RC evap coil will cool. I put a thermocouple on the FC evap air outlet during this test and the air is very cold at 20F or less. The coil has not had ice buildup that I have ever seen. I took the RC apart down to the evap fan also to check for ice and working fan. Fan is blowing fine. Every time the compressor shuts off and the system cycles on again, the RC evap seems to work fine. Once the RC hits the temp set point, the system seems to move to the FC and never gives back to the RC evap. If I power cycle the refrigerator (unplug or breaker), this starts over. RC evap works for first cycle and then does not seem to get the coolant back again. Freezer has worked throughout all of this. At one point, I tapped on the diverter valve to see if it was stuck in FC position with no effect.
UPDATE and delima. After not working for these couple of weeks, the RC is now working fine for the last 2-3 days. In this area where we live, service technician visits are difficult and take a week or so to schedule. I have one scheduled for a visit in three days and am wondering if I should cancel and see how our run of working refrigerator goes. I am concerned that the $200 cost of their trip out here is not going to help, especially now that the problem may be intermittent. I did cancel once already when I hoped the main control board that came in would have fixed it. Any advice would be appreciated.
