My freezer Controller AP3771311 stopped working Wednesday, new part came today Thursday does not light up either. The freezer is a Kenmore Elite #253.26482100 around 10-12 years old. We did replace same part around 5 years ago.
It is still running fine, just no working display panel. Will this cause a problem? We leave the temperature at -5 all the time.
How can I test the part or the wiring harness if this will be a problem.
