Yes, you need it to be hooked up in the winter also. If you don't have it hooked up then you are heating , and cooling the room at the same time.

The blink is an indication of overheating. Have you cleaned the filters? Have you made sure the exhaust tube doesn't have any kinks in it? Are you using a mains plug that has a grounding connector and doesn't overheats?
If all are how they are supposed to be then the compressor is failing - more precisely its starting capacitor: when heated it starts to short. The unit will have to be opened and the capacitor replaced - it's a special capacitor specifically made for that, you will need to get an exact replacement. Do not keep using the unit in this condition: the capacitor will eventually fail for good and it will fry the compressor in the process, killing the unit.
If you don't have the minimum experience required to do the job safely don't take any chases and call a pro.

My freezer mod#ULG80BC-5 every morning the disply

I dont provide refrigerator repair service on commercial units, but my first instinct is to say that E7 is an error code message, likely pertaining to a self diagnostic system, but you would also likely need the manual to determine the source of that error.
