# LG temperature sensor replacement cost

### Why this figure is a from

A small part behind a panel, and which panel decides the figure. LG publishes four sensor codes and they are in four different places — the freezer wall, the fresh food wall, the evaporator and the machine room.

### 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 $155, and what changes it

Confirmed on site, agreed in writing

Nothing is opened or ordered before you have said yes

Which sensor

FS, rS, dS or rT.

Whether the compartment has to be thawed

The defrost sensor sits on the coil, and the coil is usually iced when it is being replaced.

Single or two evaporator cabinet

The prefix on the code says which coil, and on a two-evaporator machine there are two of some sensors.

### 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.
