Replacing the refrigerator sensor
Liebherr refrigerator temperature sensors are among the most durable elements. Its function is to measure current temperature data in the device’s chamber and transmit information to the thermostat. Timely adjustment of parameters ensures that the correct temperature is maintained in all working compartments of the refrigerator and freezer. If the temperature sensor in a Liebherr refrigerator fails, the entire system is at serious risk, in order to Liebherr temperature sensor buy it’s worth visiting the website lb-total. ru.
Why is it necessary to replace the temperature sensor in the refrigerator: causes of failure
The design of temperature sensors is quite simple and resistant to many external factors and influences, such as mechanical loads, changes in temperature and humidity, and voltage surges. However, at the same time, the master can diagnose a node malfunction, the reasons:
- Natural aging, wear and tear over time.
- Manufacturing defects.
- Problems with contacts – rupture, burnout, separation.
- Systematic voltage drops – for electronic components.
- Contamination of the hole, ruptures, depressurization of bellows tubes.
The result is natural – there is a malfunction and the temperature sensor in the refrigerator must be replaced.
Replacing the Liebherr refrigerator temperature sensor: signs of failure
The fact that the temperature sensor has failed is indicated by a specific malfunction.
- Interruption of cooling in the refrigerator compartment. A malfunction of one of the temperature sensors is indicated by the correct temperature in the remaining chamber.
- Inability to start the compressor. The equipment does not turn on at all or stops working immediately after turning on.
- Continuous engine operation. In the event of a malfunction, the sensor stops transmitting actual data, and the engine runs without stops or pauses.
- Violation of cooling intensity. If the Liebherr refrigerator evaporator sensor does not display the temperature correctly, there is a malfunction.
If there is a problem with cooling, an experienced technician will diagnose the temperature sensor. This is necessary to correctly identify the problem.
Replacing the temperature sensor in the refrigerator: diagnostic difficulties
It is not recommended for a technician at a service center to change it yourself – disconnecting, troubleshooting, repairing. Consequences of unprofessional intervention:
- Replacing the working unit – a faulty temperature sensor is similar to many typical malfunctions when other systems fail.
- Undesirable increase in repair costs – damage to other components of the device when attempting to repair or replace the temperature sensor;
- No Warranty – Intervention will automatically void any warranty period.
A service center technician called to your home performs diagnostic operations sequentially, excluding the possibility
- Icing in non-freezing systems – ice mechanically interferes with the operation of the fan.
- Decompression – the integrity of the door seal and the condition of the sealing rubber are checked.
- Freon leaks – the presence of mechanical holes in soldering areas or capillary tubes;
- There are no problems with power supply in the circuit – the data was taken using a multimeter.
Having accurately identified the faulty temperature sensor in the refrigerator, the technician can replace the faulty component with an original spare part and provide a guarantee for the work and installation itself.
