- Instal·lar un termòstat nou:
- Mount the new Danfoss 077B-7001 thermostat in the same location as the old one, using the provided mounting hardware.
- Carefully route the new capillary tube into the temperature sensing area, ensuring it is positioned identically to the original. Avoid kinking or sharply bending the tube.
- Connect the electrical wires to the new thermostat terminals according to your documented diagram. Ensure connections are tight and secure.
- Torneu a muntar: Replace any covers or trim panels that were removed.
- Restaura l'alimentació: Plug the refrigerator back into the outlet or turn on the circuit breaker.
- Prova de funcionament: Allow the refrigerator to run for several hours and monitor the temperature to ensure proper cooling. Adjust the thermostat as needed.
5. Instruccions de funcionament
The Danfoss 077B-7001 thermostat controls the temperature inside your refrigerator. It typically features a rotary knob for temperature adjustment.
- Ajust de temperatura: Rotate the control knob to adjust the desired temperature. Numbers or markings on the knob (e.g., "Colder" or numerical settings) indicate relative temperature levels. A higher number or setting towards "Colder" typically results in a lower (colder) internal temperature.
- Configuració inicial: For initial setup, it is recommended to start with a medium setting and adjust as necessary based on the actual temperature inside the refrigerator and your cooling needs.
- Seguiment: Use a separate refrigerator thermometer to verify the actual temperature inside the unit. The ideal temperature range for a refrigerator is typically between 35°F (1.7°C) and 40°F (4.4°C).
