Product review (5 stars): Exact replacement
Exact replacement for defective sensor in my LG refrigerator.  Replacement was a bit of a pain when I got to the back plastic panel in the freezer.  Be aware that you need to remove everything in the freezer compartment - ice maker, all shelf supports, the light housing.  You will also need at least three zip ties to secure this replacement in place.  The original is zip tied to the coils in two places and the wires are bundled in a third. Doing this myself saved me several hundred dollars in service.  Just take your time, take plenty of pictures as you disassemble.

One other thing, if this went out, you likely have lots of ice buildup on the coils.  Unplugging the refrigerator will cause this to defrost but it will overflow your defrost tray.  Have plenty of towels and keep trying to suck up water out of the tray for a couple of days to prevent runoff onto your floor.
