# Electrolux defrost system repair

### On a column the ice starts where nobody can see it

A full-height evaporator is nearly a person high, and when the defrost cycle stops finishing the ice builds from the bottom upward. Weeks pass before anything is visible on the top shelf, which is why owners describe this as sudden when it has been happening since spring. The pattern of frost across the coil is the most useful evidence in the job, and it is destroyed by the first attempt to melt it — so we photograph it before anything else happens.

What this involves

Heater, the control deciding when to run it, and the drain out

On a tall column the ice climbs from below and surfaces late

The drain is the same system and is done in the same visit

Photograph the ice before touching it

Where it sits on the coil separates a heater that never ran from one that ran and could not keep up. Melt it first and that evidence is gone.

Bench-test the heater and its cut-out together, cold

Resistance on one, continuity on the other. A cut-out that has opened leaves an undamaged heater idle, and swapping the heater proves nothing at all.

Clear the drain while the rear panel is already off

Same system, same access. Skipping it is how today's defrost job becomes next month's water-under-the-drawers call.

Force a cycle and watch it finish

Signing off on a cold evaporator means signing off on nothing.

### I defrosted it manually and it came back.

That is confirmation rather than failure. Whatever put the ice there is still doing it. How long it took to return is genuinely useful information — days points at a door, weeks points at the defrost circuit.

### Does the drain get done at the same time?

Yes, and it should. It is the same system behind the same panel, and leaving it is how a defrost repair becomes a water-under-the-drawers call six weeks later.
