Frigidaire refrigerator not working
My refrigerator is only 4 years old. A few days ago it started beeping 5x every minute, as though the door might be open but it wasn't. I unplugged the refrigerator for a while, and plugged back in, and the problem seemed resolved. However, this kept happening and I have had to go through this process multiple times. Now it is beeping constantly, and not cooling at all. Any recommendations? I hate to think I need to replace such a new and expensive appliance. The model is: Frigidaire GLH68EJSBO.
Thanks much for any help!
