Kenmore w/ Freezer bottom drawer - Blowing Cold Air but not cold enough

Hey Folks,

My Kenmore (with bottom freezer drawer) has been acting up lately. The freezer stopped freezing and making ice, but still blows cool air near the ice maker. The top fridge has recently gave way as well, but still blows cool air - not cold enough to keep my food fresh.

Before I call home repair, are there any steps I can take to fix this problem myself?

I’ve also noticed a buzzing that goes on for about 5-10 seconds every once in awhile.

Thanks!
