The sensor reports freezer temperature to the control board, which then decides when to run the compressor and fans. No model list is on file, so match 4055558102 to your old sensor or confirm with your model number before you buy.

Freezer temperature sensor faults and what they cause

Modern frost free fridges rely on electronic sensors rather than an old style mechanical thermostat. The freezer sensor sends a constant temperature reading back to the control board. If that reading drifts or the sensor fails, the board is working from bad information. The freezer may run too warm, so ice cream turns soft and food thaws, or it may run constantly and over freeze. Some models show an error code or flashing display when a sensor circuit fails, and moisture in a damaged lead is a common culprit.

Replacing the freezer sensor

Turn the fridge off at the wall before you touch the sensor or its wiring. Freezer sensors are often clipped behind a panel inside the freezer, and the lead may join the loom with a plug or a sleeved joint. Take a photo first, and seal any joint against moisture once the new sensor is in. Give the freezer several hours to pull down to temperature before judging the result.

Questions about this part

How do I know the sensor is faulty?

A technician can measure the sensor with a multimeter and compare the reading with the expected value at that temperature. Error codes, a freezer that won't hold temperature and a damaged sensor lead are all clues worth checking first.
