1. INTRODUCTION This following manual objectives give you general information that will allow you can evaluate and do interventions in whole product family. Specific information like values of electrical and mechanical specifications, diagrams must be consulted in the Technical Data, sent by specific markets product codes. To Spare Parts and Exploded Views, consult the Spare Parts List.
Basically, the temperature read inside the freezer by the temperature sensor is sent to the electronic control, which controls the working of the compressor, of the fan motor, and of the heater (each 8 hours of working of the compressor (or each 4 fours in the adaptive mode, as you will see following this manual). Variables: a) The internal lamp is lighted when the door is opened.
Freezer Fan Motot Evaporator Thermostatic Damper The refrigerator air diffuser has a wind flow system, which provide a better air distribution over this compartment due to the many outlets/windows available. Protected by a front plastic cover, the air diffuser is made of styrofoam (expanded polyesthyrene - EPS). the upper part houses the damper and the diffuser complement, whereas the rear portion is provided with several seals to prevent air leaking through the sides 3.3.
Defrosts shall occur in every 4 hours (of the compressor activity), able to be reduced (adaptive) to every 4 hours (of the compressor activity) according to the usage (determined by the electronic control software). Defrost average time is from 10 to 20 min. And the maximum is 40 min., Afterwards, the product will return to its normal operation.
4.1.3. Evaporator Frost Free Type Evaporator, with suction line injected in the cabinet. Only the Evaporator can be substituted. Due the internal configuration we strongly recommend do the interventions with the lokring connections. 1. Lokring connector 2. Defrost sensor 3. EPS - shim right 4.
4.2.3. Thermofuse Turned on in series connection with the heater defrost, the thermofuse protects the product and does not allow that defrost heater be turned on continuously in case of failure of the defrost sensor. In case of failures in the defrost system when the heater is continuously working, it will open at the range of 72 °C to 77 °...
4.6. Interface Board (LCD Display) The Interface board has the function of interacting with the user, indicating the product functions/programming and operation (see use characteristics item) always put in operation by the electronic control. 5. TESTS Two automatic test routines are available in these refrigerators in order to prove the main components of the product: one executed automatically by the software of the electronic control, when the product is plugged on the power supply and other handled by the own technician, which are described as follows: 5.1.
Notes: 1 - During the Automatic Test Routine, even if the doors are open, the Fan Motors will not turn off; 2 – If the product is in Defrosting mode, this routine will be aborted, because the defrost function has priority over the others Summarily, the steps described above can be seen graphically.
Service test routine steps Step Displayed Code Action / description Runs the User Interface check performing the short circuit test for all LCD segments till the OK button is pressed; N - 1 Runs the N - 1 phase Runs the current phase N - 1 Reset and restart.
5.4.2. Temperature Alarm If the Electronic control detects a high internal temperature (above –12° C), at the freezer compartment, it will activate the Alarm Icon and the Freezer Temperature Icon “–12° C” will blink. Note: To prevent “wrong” alarm, this alarm status is disabled on the following circumstances: During the first 6 hours after the product is connected to the energy;...

If the Temperature Set is on Advise the consumer. On the proper position. days too hot or with the Refrigerator too full, the Temperature selection hould be set to maximum position + 1 ºC. If there were excess door Advise the consumer. openings or open doors.
Page 15
If the refrigerator door Advise the consumer to remains open for more than close the refrigerator door 2 minutes and explain the Open Door Alarm system to her/ him, according the Alarm system item on this Manual. Alarm activated If the Electronic Control – Check if all interface PCB is working properly.
If the refrigerator is clean Advise the consumer to inside. clean it with warm water and neutral soap. Unpleasant If still hot, unpacked, or Advise the consumer. smell or taste on uncovered food was stored. the food. Smell of brand-new Advise the consumer to product.
4. Loose all other screws and remove the Electronic Control. IMPORTANT # Be careful when using the Multimeter measuring probes, as they may damage the connector terminals. # Be careful when removing the electronic board connectors, as they are latched. Remove them at right angles with no side movements.
3- Release the screws that are attaching the Interface board; 4-Remove the Interface board; 5-Disconnect the wire connector and take out the Interface board; WARNING : Electrostatic Discharge Risk Do not touch the Circuit components, because you can damage, fuse/burnt or weaken the board. Always handle the Boards by the sides/plastic holder.
7.4. Air Diffuser 1. Remove the lamp protector. 2. Loosen the fastening screws. Disengage the diffuser from the roof and loose the lamp connectors. 4. Cut the seals with a carpenter knife. 5. Remove the diffuser complement.
6. Remove the fan motor 7. Remove the Membrane details. Note: This membrane has the function of avoiding the air re-flow (return) and must not be removed under any circumstances. 8. When reassembling the set redo the air Duct sealing. Important: Never remove the seals located at the rear of the air diffuser.
3. Install the new evaporator and the lokring connectors, do vacuum in the system followed by the original load of R-134a. Important: Those shims should not be removed from the product. If they are missing, problems could occur such as low refrigeration or frost formation in the freezer compartment. REMINDER: Follow the specific instructions for interventions on the hermetic systems.
3. Now insert one of the wiring cable into the connector; 4. Then insert one of the sensor wires into the same connector; 5. Using a pliers, press the connector blade. Internally, this blade will lock both wires doing the electrical connection between them.
