Mabe No Frost refrigerator makes a lot of frost in freezer

Good day, I have a MABE RML10XHM refrigerator, it turns out that they changed the card because it did not start the engine, when it changed it worked fine for a few days but then it began to accumulate a lot of frost in the freezer, they already changed the card again, (for the third time ), but it continues to accumulate a lot of frost, I think it can be the Bimetal since the resistance was tested directly and if it heated. Please help me to see what may be failing. Thanks friends.

When the bimetal cools it, it must let the current pass and when it is heated with a positive temperature it must cut the current, see if there is a thermal fuse that may be failing, I do not understand why they changed so many cards without first controlling the bimetal and the entire defrosting system, if they made sure that the forcer works and that the defrosting duct that goes to the compressor motor is not covered with ice.

Hi Burgos, you have to check (bimetal, forcer, thermal fuse and clogged drain) greetings.

Thanks Gustavo.
The drain I understand that it is the drain for the thaw and is not covered, and I understand that it has no thermal fuse, it would only be necessary to check the bimetal and the forcer. In the case of bimetal I encourage you to change it since it is cheap, although the new one would be a standard. Regards

All non-frost refrigerators carry thermal fuse, but I think in this model you have them in the resistor (2) where the terminals go, but we know they work because you tested it directly and it heats.

If your refrigerator I think that if you carry the card underneath in the conservation zone, check that the ambient sensor is in the corresponding position.

Hi Gustavo, I tested the resistance directly and this time it did not heat all but only a small section of about 7 centimeters, I think the resistance is bad because it should heat up completely. What do you think?

how long did you pretend it, at least 5min.

Well, I tried it for 10 minutes. I decided to change resistance and the new one already brings the bimetal so I ended up changing both things and for the moment it has been working well for 8 days. Thanks for your help

Dear Yecith for more attention the next time ask your individual question and not in an existing question that gives us a greater order; Regarding your question check the resistance, fuses and thermal sensor of the refrigerator as Gustavo Gabriel recommends. This is done by means of a multimeter device set in ohms at each end of the resistor if it produces an approximate reading of its value is fine.

Thank you, I'm new and I still don't have experience on the page

there is another option to avoid expenses and setbacks, just do the conversion to analogue, set a manual thermostat and a timer, with that solve the problem, good luck;)

you can force the defrosting on the card, if you can upload an image and I tell you which bridges you pin to thaw and so see if the thaw works, there a model that brings bimetal and sensor, I don't know if yours just has the bimetal and the temperature control sensor below, if you could tell me, regards

Good morning and thanks for commenting.
I tell him that I had not had time to check the refrigerator, but I tried the resistance again and it turns out that it did not heat all, but only a section of about 7 centimeters of the resistance, I imagine that it should heat completely, so I thought to change it and see If that is solved.
