Refrigerators

Fridge Whirlpool WRW41AEDAR no frost, does not cool the refrigerator.

The refrigerator Whirlpool WRW41AEDAR no frost, began to stop cooling in its bottom or refrigerator. I checked the freezer compartment and it was full of ice and frost. I checked the components and changed bimetal, resistance Ok, temperature sensor ok, electronic board ok. The electronic board is very similar, almost exactly the same as the MABE platelets with potentiometer and 5K ohms sensor. The 220Volts power supply is stable and has no cuts or marked fluctuations. Actually, I no longer know what else to check and the client also says she perceives excessive warming of the front edge of the freezer, that is, where the doors rest, where the discharge tube passes internally. The refrigerator has 1 year of use and after the warranty, began with the malfunction. Thank you in advance to all colleagues for their time and collaboration. Best regards.!!

I had doubts when I found that plate, but I was the first person who touched the refrigerator ...
I live in Quilmes, Buenos Aires Argentina and all businesses in the area could not believe I had that plate, they told me that it seemed incredible that whirlpool used these platelets, especially in a refrigerator that currently costs between AR $ 35,000 and AR $ 40000.
But certainly the refrigerator was intact until I intervened.

Did you control the sensor?
What temperature is the refrigerator and refrigerator?

The room temperature sensor, greater than 25C, has a value of 4.75k ohms.
Freezer temperature is higher than -20C.
Thanks for asking! Regards

Control the relay that activates the resistance, you have to desolder it and test it outside.

It is checked, short-circuiting the 2 pins that the board has, defrost mode is forced and the resistance works.

Is the equipment going? Cut the compressor at temperature?

Hello triatlon99, a while ago I found the damn fault, the compressor did not cut, because the temperature sensor did not reach the cold once the passage of air to the refrigerator was frozen.
The defect was in the damn bimetal that had already replaced, so it worked for several days and failed again, with the new bimetal I focused on the platelet, but the newly placed bimetal failed. Then I forced the plate into defrost mode and the bimetal current did not pass to the resistor, so I put a Whirlpool type with hot melt and was walking.

check the refrigerator fan ... and it is normal for that part to heat up as it is designed so that moisture is not created around the door

Thanks Alaen, the fan is working properly, however the air flow in the refrigerator seems little, but the forcer works perfect.

I mean, it seems "little", because it really feels a gentle breeze in all aerators, but it would give me the impression that it is not enough

If you feel "breeze" is normal, there is no choice but to check pressures and check that the amount of refrigerant is correct.

Good morning colleagues! How I already told friend triatlon99 a while ago I found the damn fault. The defect was in the damn bimetal that had already replaced, so it worked several days and failed again. With the new bimetal I focused on the platelet that had no defect, but the newly placed bimetal failed. Then I forced the plate in defrost mode and the current did not pass from the bimetal to the resistance, so I changed it again to a Whirlpool type with a hot melt in series and it was going well. Thank you all for taking the time to read and comment! Best regards NICOLÁS.
