# LG defrost system repair cost

### Why this figure is a from

Heater, sensor and control, and the cabinet has to be properly thawed before any of it is reachable. That thawing is most of the time on the job and none of the part cost, which is why this row sits above a straight sensor replacement.

### What puts your job at the bottom or the top of it

At the bottom: one appliance, a code or a light pattern already written down, easy access, and a cause that turns out to be a setting, a filter or something cleared rather than replaced. At the top: a machine built into joinery, a part that has to be ordered rather than picked up, and a second problem found alongside the first. We say which of those you are in before the work starts, not after.

What moves this figure

from $175, and what changes it

Confirmed on site, agreed in writing

Nothing is opened or ordered before you have said yes

How much ice there is

Three weeks of frost and three months of it are different visits.

Which part has failed

LG codes the sensor as dS. The heater has no code and is measured.

Whether the drain iced with the coil

Usually it did, and clearing it while the machine is open avoids a leak call a fortnight later.

We say which of those you are in before the work starts, not after.

### Why is it a from and not a price?

Because the same job is not the same work on two machines. The part, the access and what the appliance turns out to have done to itself all move it, and quoting a number before measuring is guessing with extra confidence. The figure is confirmed on site and agreed in writing before anything is opened — BRAND-RULES is explicit about it and so are we.

### Is the diagnostic charged on top?

It pays for the diagnosis, which is real work. If you go ahead with the repair it comes off the bill, so you pay it once either way.
