4055922902 Genuine Fridge Control Thermostat for Electrolux Group Fridges and Freezers, Temperature Control, Also 1416543

Part 4055922902 is a genuine Electrolux control thermostat for fridges, also listed under the older number 1416543. It is the thermostat that senses cabinet temperature and switches the compressor on and off to hold your chosen setting. No models are on file, so the number on your old thermostat is the best guide. Match 1416543 or 4055922902, or send us the model and product number to check.

Fridge too warm, freezing up or running nonstop?

A typical fridge control thermostat uses a gas filled capillary tube to sense temperature. As the cabinet warms, pressure in the tube rises and closes the contacts to start the compressor. When the contacts wear or the capillary loses its charge, the fridge may never start cooling, run without stopping and freeze food, or cycle on and off far too often. Turning the dial and hearing no click is a common sign. Check the power supply and listen for the compressor before deciding the thermostat is the culprit.

Changing the thermostat

Switch the fridge off at the wall and unplug it. Take a photo of the wiring and note exactly where the sensing tube is clipped, because the new tube must sit in the same spot to read correctly. Avoid kinking the capillary as you route it. Refit the knob, power up and let the fridge run a full cycle before adjusting the setting.

Questions about this part

How do I know the thermostat has failed?

With the fridge unplugged, disconnect the thermostat and test across its terminals with a multimeter while turning the dial. If the contacts never close or never open, it is faulty. Also confirm the compressor and start relay are working, as they can fail in similar ways.
