why is the green LED light flashing?

hi my freezer difrosted by itself and now is not freezing again do i need to change the relay??

Hi Jacob, thank you for reaching out. Yes, the issue could be because of the compressor start relay. It can fail if its internal ceramic disk cracks or burns out, interrupting the electrical path needed to start the cooling system. Without the initial power surge to the compressor motor, the unit remains idle and cannot produce cold air. Replacing it will indeed help fix the issue. The part number is PS16620630. We hope this solves your problem!

so not to disrupt items on the shelves we purchased an extra shelf
so we could flash freeze items on a baking sheet after they are frozen then placed in a seal meal bags
the items won't stick together
the extra shelf allows you about 3 inches of space for a backing sheet
