Product review (1 stars): I have had and am having the exact same issue ...
I have had and am having the exact same issue as many others with this refrigerator. In addition to the door alarm, the lights flicker and the fridge cannot always maintain temperature. Installed the fridge/freezer combo in our brand new kitchen with brand new wiring in July, 2016. Problem started in September. Repairman came out 4 times to replace the control board. None of them ever worked - before he left, the same issues would happen. Frigidaire and Hahn's Appliance replaced the fridge in January. Before the Hahn's delivery and install guys left, the new fridge was doing the exact same thing. We have had different electricians come out to verify the wiring in our house was done properly. We have plugged the fridge into different outlets on different circuits. Always the same problem. I doubt I'll ever buy Frigidaire/Electrolux again, nor any appliances from Hahn's.
