Why does freezer frost keep coming back after melting?
Melted frost often returns quickly because warm air continues to leak into the freezer, usually from a door left ajar or a compromised seal. When the ice simply gets melted without fixing the root cause, the frost builds right back up on the coils even worse within a month.
