Hi Sergio,
We understand the importance of a door panel capable of holding magnets. Let us get you information about this question.
In the past, Samsung has increased the amount of ferrous material in the stainless steel panels to make them magnetic, however, we do not have records of which models are magnetic
To be on the safer side, we recommend visiting Best Buy or calling them at Phone: (888) 237-8289, their customer service is open 24 Hours a Day and they can physically check for you in the store if the unit is magnetic.
