What is an evaporator?
The coil inside the freezer where refrigerant boils and absorbs heat, this is where cold is actually made.
Hidden behind the rear freezer panel, the evaporator is where liquid refrigerant boils into gas and pulls heat out of the compartment. A fan blows air across it and distributes that cold through the fridge. Frost naturally forms on it and is cleared by the defrost cycle. When defrost fails, the coil turns into a solid block of ice, airflow stops and the fresh food section warms while the freezer stays cold. Frost on only the first pass of the coil instead points at a low refrigerant charge.
