good morning, I have a MABE no frost refrigerator that works 10 in frezzer but not below I made a bimetal change and unblock the drain pipe I had as a barrel and a nylon that covered it, but after 10 days they let me know what to do again the same problem
° I checked the resistance and I see it works (I measured it in hom) I don't remember how much but it marked me
° the forsador turned well
° when connecting everything worked for me 10 cut and everything ok
the board seems to have nothing weird (attached photo)
I appreciate that more information is not trying greetings

J1 and J2, are two points of connection that when we want to do for example a forced defrost to test the proper functioning of the entire electrical and electronic defrosting system. We join those two points once, or twice, until the team is performing in test mode, the process we want to evaluate.

Defrost resistance does not lose its values, unless it is opened or split. One area always works hotter than the other, especially when cornering.

Hi Jose Amaya, check the good condition and operation of the defrost resistance relay on the electronic board. When defrosting, connect a clamp meter in one of the two wires of the phase current inputs, and take the consumption and time that the bimetal remains active, passing current to the resistance. The bimetal must exceed 15 minutes of work, if it does not succeed you must replace it with a new one and the total defrosting process must exceed 30 minutes, including 15 minutes of the minimum bimetal. Check the frequency of entry to the defrosting process of the Timer on the electronic card, this entry time must range between 6 and 8 hours maximum. Luck. S @ lu2 friovega63.

Look at this test, take off the cover and disconnect the fan, let the whole coil fill with frost, since it is all full, you will bridge J1 and J2 with a wire or with the flat screwdriver for a moment until you hear the cut compressor, you should heat the resistance and in about 30 minutes or so you should restart the compressor, if you do this, that part would be fine, you would go with the sensor below, the temperature control, leave the card suspended together with the sensor, then made to fly the equipment, and after 10 minutes or so with liquid refrigerant you apply it to the sensor, that is, you splash it and it must cut the compressor, if it does not cut it changes that sensor, one more thing Before doing that test, check the potentiometer that is on the card, you must measure what it indicates on the body of the card, I do not remember, but it brings it engraved in the plastic, ahh I passed a detail the drain sheet that this good that I have no wrinkle and test with water that the same goes well in the hole, pour water and should go down at high flow, check that the hose is not covered the one that goes in the tank, I also put an aluminum wire hugging the resistance and that rests on the drain hole, many refrigerators of this brand bring that wire, in case you do not bring it you make one, greetings

Let's see my dear, what was not understood? When I bridge the compressor short, it happened to me to tell you to leave the cover removed and the fan disconnected, this when you cut the compressor, go to where the resistance is and see that it is heating, I hope it has been understood, greetings

if you notice that it does not heat, it could be the bimetal or the same resistance or the card relay does not activate, when you cut the compressor you hear a first ckick and then a second click, if you only hear one, it is the bad card, regards

the plate repaired again but the refrigerator did not go cold down again? Does the separation of the back fence have to do with respect to the wall? If not, I am going to try a change of resistance and I am ready, I don't know what to do because I have the bimetal plate replaced. There is no obstruction in the pipe.
