Sub-Zero: Making Loud Noise

Buzzing, grinding, or rattling on a chest or upright freezer usually maps to evaporator fans hitting ice, condenser fan wear, or compressor mount vibration — we isolate the source before replacing parts.

Sub-Zero: Frost Build-Up

Heavy frost on the evaporator cover or gasket corners usually means defrost did not finish, a seal leak let humid air in, or the fan could not move air past ice.
