5. Használati útmutató
The Danfoss 25T65 077B0033 thermostat operates automatically to maintain the set temperature within your refrigerator. Once installed, the thermostat senses the internal temperature via its capillary tube and cycles the compressor on and off as needed.
5.1. Hőmérséklet beállítása
Temperature adjustment is typically done via a control knob connected to the thermostat shaft. Rotate the knob to select the desired cooling level. Higher numbers or colder settings will result in the compressor running more frequently, leading to lower internal temperatures.

5.2. Kezdeti működés
After installation and power restoration, allow the refrigerator several hours to reach the set temperature. Avoid opening the refrigerator door frequently during this initial period.
6. Karbantartás
The Danfoss 25T65 077B0033 thermostat is a sealed unit and requires no routine maintenance. However, ensuring the refrigerator's overall cleanliness and proper functioning of other components can contribute to the thermostat's longevity.
- Regularly clean the refrigerator interior and exterior.
- Ensure the refrigerator door seals are intact and functioning correctly to prevent warm air from entering.
- Keep the condenser coils clean to allow for efficient heat dissipation, which can impact the thermostat's performance.
7. Hibaelhárítás
If your refrigerator is not maintaining the correct temperature, the thermostat may be a contributing factor. Before assuming the thermostat is faulty, check other common issues.
7.1. Gyakori problémák és megoldások
- A hűtőszekrény nem hűt:
- Ellenőrizze, hogy a hűtőszekrény be van-e dugva a konnektorba, és kap-e áramot.
- Ensure the temperature control knob is set to a cold enough setting.
- Verify that the condenser coils are clean and not obstructed.
- Check if the door seals are intact and the door is closing properly.
- If these checks do not resolve the issue, the thermostat or compressor may require professional inspection.
- Refrigerator Too Cold (Freezing Food):
- Adjust the temperature control knob to a warmer setting.
- Ensure the capillary tube is correctly positioned and not dislodged.
- If the issue persists, the thermostat may be faulty and require replacement.
- Compressor Runs Constantly:
- Ellenőrizze az ajtótömítések szivárgását.
- Ensure the refrigerator is not overloaded with warm food.
- Verify that the condenser coils are clean.
- A constantly running compressor can indicate a faulty thermostat that is not cycling off, or a problem with the refrigeration system itself.
For complex issues or if you are unsure about any troubleshooting steps, contact a qualified appliance repair technician.
