# Dacor frost building up inside the freezer column

### What to do in the next ten minutes

Look at where the ice actually is — around the gasket, at the back wall, or under the drawers. Run a slip of paper round the door seal and feel for even drag. Check nothing is holding the door a fraction open, including a drawer not fully closed or a packet caught at the edge. Note how long since the cabinet was last emptied and defrosted, if ever.

### Frost-free does not mean frost-proof

These cabinets stay clear by running a defrost cycle that melts what condenses and draining it away. Every part of that — heater, sensor, timer, drain — can fail, and each produces ice in a slightly different place. The location of the frost is the most useful thing an owner can tell us.

### Humidity here does the rest

A door opened twenty times a day in an eighty per cent kitchen admits a great deal of moisture, and a marginal gasket that would pass in a dry climate will frost a cabinet here within a month. The seal is worth more attention on this coast than the manufacturer’s interval assumes.

The door is letting warm air in

A gasket that has lost contact, a hinge that has settled under a panel front, or a drawer left proud. Warm humid air meets a cold cabinet and the result is exactly this.

The defrost cycle is not finishing

Heater, sensor, thermostat or the control that times them. Ice accumulates on the evaporator until air can no longer cross it, and the cabinet slowly loses its ability to hold temperature.

The drain is blocked

Meltwater that cannot leave refreezes under the drawers, which is the version people notice first because it makes the drawers hard to pull.

Note where the ice is

Door and top, or back wall and under the drawers. Two different repairs.

Paper-test the gasket all round

Even drag everywhere, or one slack edge. The slack edge is the answer.

Check the drawers close fully

A packet caught at the edge of a drawer holds the door open all night, every night.

Ice on the walls, on the packets, and around the drawers

What it usually means

Where the ice forms tells you which problem it is

Around the door is air getting in; at the back wall is defrost

In a column the build-up starts low and shows late

### Should I defrost it manually?

It will clear the symptom for a few weeks and it will not fix the cause. If you need the space, do it — but the same ice will return on the same schedule until the problem is found.

### Is the food still safe?

Frost on packaging is cosmetic. Food that has softened and refrozen is a different matter, and the giveaway is ice crystals inside the packet rather than on it.
