The klixon is a security system that prevents overheating of a refrigerator or freezer by automatically cutting the compressor operation from a certain temperature. It is in some way a thermal switch. It takes its name from the American brand which is the main manufacturer. Do not forget to turn off the power supply before working on the device. When the klixon malfunctions, the device no longer works. Replace the faulty klixon with a similar or equivalent model recommended by the manufacturer.

- Phillips screwdriver
- Needle-nose pliers
Disassemble the klixon from the chest freezer
1. Like refrigerators, freezers (here a model chest) have a klixon placed near the compressor. Locate the power supply box, located at the back of the freezer, at the bottom of it.
2. Using a flat screwdriver, unscrew the power supply box cover first.
3. Locate the screw of the grounding conductor terminal and that of the housing itself. The ground conductor screw helps maintain the housing.
4. With a cruciform impression end fitted to the screws, undo them. Be careful to recover them to put them back in place later!
5. With both screws removed, remove the power supply box.
6. Locate the relay located on the back of the power supply and dislodge it to access the klixon.
7. Now clear the faulty klixon. Disconnect the lug with a needle-nose pliers and remove it.
Refit the klixon of the chest freezer
1. Take the new klixon and reconnect its power terminal to the finger. It is essential to take a klixon strictly identical to the one just deposited.
2. Embed the klixon in its housing, inside the case.
3. Now replace the relay in the power supply box.
4. Replace the housing. The reclipser on its support.
5. Replace and tighten the housing retaining screws.
6. Finally, replace the housing cover. The klixon of the chest freezer is replaced.
