Freezer interior light blinks continuously, code 8 comes up on the front door panel, high temp light is on the front door panel, temp number on door panel always resets to 3 then freezer will cool briefly maybe a week then quits running again. When you open and close door it sounds 3 short beeps when you close the door. Freezer was bought in 2008. After it quits running we have to unplug it and it gives the above stated codes then works briefly before quitting again. Is it worth fixing since the freezer is almost 8 years old.
