Frigidaire upright freezer not freezing
I removed panel inside the freezer, fan is spinning, coils are frosty but not overly frozen. Defrost thermostat and heating element appear good, did not put meter on them, since coils were merely frosty. Nothing seems to be protruding to keep the door from fully closing. Temps fluctuate between 35-50°. Where do I need to start looking?
