This document serves as a service manual for Teka RBF range refrigerators, specifically models RBF 78720, RBF 78630, and RBF 74620. These models are electronic no-frost refrigerators, designed to allow independent temperature adjustment for each compartment, ensuring no air flows between them.
The Teka RBF refrigerators are designed to provide efficient and independent cooling for both the refrigerator and freezer compartments. The core functionality revolves around maintaining precise temperatures in each section, preventing frost buildup, and offering various operational modes to suit different user needs.
The compressor operates until both compartments reach their target temperatures. If the refrigerator compartment reaches its desired temperature before the freezer, a heater element in the refrigerator is activated to prevent excessive cooling, ensuring that the compressor can continue running to cool the freezer without over-chilling the refrigerator.
The refrigerant circuit involves a compressor, condenser, capillary tube, dryer, and two evaporators (one for the freezer and one for the refrigerator), each with its own fan. This setup facilitates the no-frost operation and independent temperature control.
The refrigerators are equipped with a control panel that allows users to manage and monitor various settings and modes.
Control Panel Elements:
Temperature Setting: To adjust the temperature in either compartment, the user first presses the sensor corresponding to that compartment to select it. Subsequent presses will cycle through the available temperature settings. Once the desired temperature is displayed, it is automatically saved after a few seconds.
Temperature Ranges:
Operating Modes:
First Start-Up Sequence: Upon initial power-up, if the defrost sensor detects a temperature above -5ºC, the refrigerator initiates a sequence: the compressor and fan run for 5 seconds, followed by the defrost element and refrigerator heater element also running for 5 seconds. After this, the refrigerator pauses for 5 minutes before commencing normal operation. Settings are retained in memory after a power outage, eliminating the need for re-configuration.
The service manual outlines various diagnostic and maintenance features, including a service test mode and error message interpretations, to assist technicians in troubleshooting and repair.
Service Test Mode: To enter service test mode, the user must press and hold the "Freezer Set" sensor while opening and closing the refrigerator door three times. After a 3-second delay, the service test is launched. If any component has failed, an error message will be displayed; otherwise, the display remains blank. While in service test mode, an audible "beep" sounds every 5 seconds, and the Child Lock LED blinks. The "M" sensor is used to navigate through different functions within this mode.
Service Test Functions:
Error Messages: The manual provides a comprehensive table of error messages, displayed as "SR" followed by a code (e.g., FE01, FF12), and their corresponding descriptions. These messages indicate specific component failures or operational issues.
Sensor Failure Troubleshooting: If a sensor failure is indicated, technicians are advised to:
Alarm Suppression Conditions: To prevent false alarms, error messages are not displayed under specific conditions:
Defrosting Cycles:
Component Checks: The manual includes tables for checking temperature sensors, providing resistance values at different temperatures for both "Congelador y conservador" (freezer and refrigerator) and "Desescarche" (defrost) sensors. It emphasizes that sensors must be disconnected from the control board and their real temperature measured for accurate comparison.
This detailed overview ensures that technicians have the necessary information to diagnose, troubleshoot, and maintain the Teka RBF refrigerator models effectively.
