the temp lights no longer come on. doesn't seem to cool

We have a worpool gold refrigerator model # gd5nvaxwa00. The display in the thermostat panel doesn’t light up after a power outage. All the other lights work fine. We unplugged it for 5 min or so and the lights came back on and the compressor came on. After a short time it went out again and the compressor doesn’t come on after the lights go out. It did happen before but worked fine for a couple of months after unplugging it for a little while. But doesn’t seem to work this time. Any ideas. Thanks
