Question

Our electicity went out for a couple of minutes yesterday. Ever since then, the refrigerator side of our side by side twin cooler unit has had a slow temp. increase. It's now up to 54 degrees, The freezer side is at 0 and appears to be working fine. The freezer is set for 0 and the refrig. is set for 36. Power Cool setting does not seem to help. Any suggestions? Thanks!
