Bar between side by side ref. door is hot

My samsung refrigerator is 6 years old model #rs2530bwp and the bar between the side by side is so hot I burned myself when I leaned against it. Along the top/side/bottom of the freezer where that panel continues is also hot. (the frame of where the doors hang. the right side where the refrigerator part is is cool. Has anyone else experienced this and does anyone know what cause is and is it dangerous. I have it turned off now afraid of fire or something

Hi.

Pull the fridge out, remove the rear bottom cover and check if the condenser fan motor is running. Replace it if needed

Also clean the condenser coils while you are there.

Post the results.
