Good morning - evenings - nights
My son has a non-Frost refrigerator and is paradoxical since a lot of ice is added to the base of the lower tray.
It also throws water on the floor.
I would appreciate telling me what to check to solve the problem mentioned.
In 5 days a large amount of ice is collected that prevents the lower tray from being removed.
Greetings.
Have a happy new year.

    Hi Ennio, obviously the drilling of the drain hole to see it must first remove, the back cover of the inside of the freezer itself, after first removing all the drawers. S @ lu2

3 Proposed Solutions

SOLUTION ACCEPTED
Hello Ennio, it would be good to get the manual of services for that model, maybe in it, club of diagrams.com find it, and to start you can check the usual, defrosting and environmental sensors, usually range between 5k and the 10k kilo ohm, if it is to invert the environmental sensor inside the freezer it may be 2.5 kilo ohm and 5 kilo ohm the defrost, at a temperature of +25 degrees Celsius and with the multimeter placed on the 20 kilo scale ohm, eye don't use another scale for measurement because it can report reading errors. You should also check the thermal fuse, defrost resistance and even check the drain, you know that a clogged drain can create that problem. Check everything and comment please. Luck.

    Thanks friovega63.
    I will download the manual, to know where the drain is.
    So I tell my son since he is in another city 150 km from here. On January 12 I travel and I can do something.

    Thanks to you Ennio also for the communication, if you share the service manual, with it I can from here help you better, if you wish, we will keep in touch. S @ lu2.

Good colleague Ennio, if the freezer is in the lower part of the refrigerator, because precisely the drain is possibly clogging and that area is filled with ice, causing that the lower tray cannot be removed, check resistance, defrost sensor, fuse thermo and that the drain is uncovered, greetings and happy holidays

    Hi Fermin
    Do you know where the drain hole is located?
    Because my son told me today that the perforation is not visible when removing the lower tray.

    Hi Ennio
    I have been very busy, it is as the cold colleague (greetings) says, remove all the trays and then the false lid that is behind the freezer and below must be the drain hole, if it is covered with ice, use boiling water or a hair dryer to remove the ice that covers the hole, and then check what I advise, back must have a diagram, which indicates if it brings more than one resistance, these systems usually bring more than one, greetings and Happy New Year , also to the cold colleague.

Good afternoon, dear colleagues.
Today at my son's house we begin to review it.
Indeed, as you mentioned, the drain hole was completely frozen. The one that was not uncovered from behind where is the tube that unloads in the tray.
The defrost resistance is 400 ohm which is discarded. The same as the thermistor that measured 13 kohm.
After removing the ice, we managed to uncover it.
The image is only from the drain pipe when it was already uncovered.
How the solution is one, the other I give my positive rating.
Thank you for your answers
