The alarm on my Frigidaire refrigerator (Model LGUS2642LF1) keeps going off. Other than the annoying alarm, it appears to be working fine in that it feels cold and the readouts say that it is keeping the correct temperature. I have tried resetting the alarm many times, and turning the unit on/off a couple of times. What is weird is that when/how often it alarms does not appear to follow any set pattern. I did have a power outage a few days back so I am afraid it got a power spike that did something to one of the circuit boards. I am fairly handy is there something that I can do to diagnose the issue? Thanks
