mi refrigerador congela, pero luego hace escarcha y deja de congelar
Dear Sir or Madam,
I am experiencing a serious recurring issue with my GE Profile refrigerator, and I am looking for clear technical guidance.
Initially, the refrigerator was not freezing properly, and it was diagnosed that the evaporator fan was faulty. The fan was replaced, and after that repair the unit started freezing very well.
However, after several days of normal operation, excessive frost builds up in the freezer area (where ice is produced) and also on the interior back wall of the refrigerator compartment. When this happens, the refrigerator stops cooling, presumably because airflow is blocked by ice buildup behind the evaporator.
If I manually defrost the unit, it works correctly again for about 3–4 weeks, but then the exact same problem occurs again.
Based on this behavior, I strongly suspect a failure in the automatic defrost system (defrost heater, defrost thermostat/bimetal, temperature sensor/thermistor, or control board). Since the evaporator fan is new and the issue is cyclical, it does not appear to be an airflow or cooling-capacity problem.
I would greatly appreciate a proper technical diagnosis so I can guide the repair process correctly, as previous technicians have not been able to identify the root cause.
Thank you very much for your assistance.
Kind regards,
Is this a good question?
Hi @fernandoca68986
What is the model number of the refrigerator?

The refrigerator model is PKCN3FFFFBN.
I have attached some current photos showing the frost buildup that is forming now. In a few more days, frost will also appear on the rear interior wall, as shown in the second photo.
Additionally, there is a tube at the back of the refrigerator that always freezes. It appears to be a copper tube, and it consistently becomes covered with ice when this issue occurs.

Unfortunately I can't find any information regarding your model, not even a parts list.
Check the following places to see if there's a service sheet for the refrigerator.
Behind the front grill (in the center or on the left side).
The left or right side by the condenser.
Inside the Refrigerator section in the control panel.
GE usually places one in each product they make. If it is there it will show you how to enter the diagnostic test mode, so that you can individually test all the functions of the refrigerator.
