What it
usually means.

Frost is water that arrived as humid air and never left. On an automatic-defrost appliance it should be cleared several times a day, so visible frost means either that the defrost cycle is not completing or that far more humid air is getting in than the cycle was designed to handle. Where the frost sits tells you which of the two it is.

The rear evaporator panel removed inside a freezer, exposing the coil and the defrost heater element beneath a layer of frost. The 4 causes, cheapest first

Answer these first

01

Where exactly is the frost: the back panel, the door seal, the ceiling, or everywhere?
02

Is it a hard clear sheet or a soft white fur?
03

Does the appliance defrost automatically, or is it a manual model?
04

Has the humidity in the room risen, or the door been opened more than usual?
05

Is the fresh-food compartment warmer than it used to be?

Frost buildup in refrigerator: 5 checks, and none of them costs anything.

01

Note where the frost is and tell us; it separates a door problem from a defrost problem immediately.

02

Check whether the model is automatic or manual defrost.

03

Inspect the gasket for hardening, tearing or a gap at a corner.

Also worth checking

  • Look for a sheet of ice under the bottom drawer.
  • Note whether cooling has changed as well.

How soon does it need a visit?

Not urgent on its own, but frost over the evaporator ends as a cooling failure. Booking while the food is still cold is the cheaper path.

4 things frost building up in the refrigerator turns out to be, from manual-defrost model overdue to defrost drain blocked and refreezing.

The cost guide
  1. 01 no repair

    Manual-defrost model overdue

    On a manual model this is maintenance and there is nothing to repair.

    No repair: check it yourself
  2. 02 low

    Door seal admitting humid air

    Frost concentrated near the door line points outward, at the seal, rather than inward at the defrost system.

    Fixed by door, gasket and alignment See refrigerator door not sealing
  3. 03 low to moderate

    Defrost heater or thermostat failed

    Frost building evenly over the back panel inside the freezer is the classic pattern, and it ends as a cooling complaint if it is left.

    Fixed by defrost system repair
  4. 04 low

    Defrost drain blocked and refreezing

    Meltwater that cannot escape freezes where it stands, producing a sheet of ice in the bottom of the freezer.

    Fixed by drains and leaks See refrigerator leaking water on the floor

Questions about
frost building up in the refrigerator.

Is frost on frozen food packages the same problem?
Not quite. Ice crystals inside packages, usually called freezer burn, come from moisture leaving the food, and they grow faster when the temperature swings or the door is opened often. Heavy crystals on every package together with frost on the walls do point back at humid air getting in.
Does a frosted freezer use more electricity?
Yes. Frost insulates the coil, so the compressor has to run longer to move the same heat. It is one reason frost and constant running so often arrive together.
How fast does the frost come back after a manual defrost?
If the defrost system has stopped working, a thoroughly melted freezer usually frosts over again within days to a couple of weeks, depending on how often the door is opened. If it stays clear for months, the original frost was more likely a door left ajar than a failed part.
Why is the frost only at the front of the freezer drawer?
A drawer that is overfilled or slightly off its rails does not close fully, and the humid air it lets in freezes nearest the gap. Frost at the drawer front points at the drawer and its gasket; frost at the back of the freezer points at the defrost system, on any layout.
