Convection oven fans were noisy.
This oven has two fans that counter rotate. One spins clockwise, the other counterclockwise. Because of this, the motors and the fan blades are different. The schematic shows the counter clockwise rotating fan with a right hand threaded shaft/nut on the bottom and the clockwise motor and fan with the left hand nut on the top. My range had the motors in the exact opposite orientation, but the fan blades on the motors as shown on the schematic. The incorrect assembly at the factory (I bought new in the box, so I know this is the first repair) meant that nether fan blade was turning the correct direction. So do yourself a favor, be sure you’re buying the right motor (clockwise or counterclockwise) and be sure you put the right fan blade on the right motor. The Samsung motor ending in F is the counterclockwise motor that has the right hand threaded shaft the clockwise motor with the left hand threaded shaft ends in E.

Oven shut off during self clean cycle and door stayed locked.
I took off the back cover after I looked at youtube similar problems. Then removed the little thermostat and un hooked the 2 wires. I looked up the part and after is was delivered couple days later I connected the 2 wies and after putting the back cover on the oven was back to normal. Was such an easy repair and the part was only $11.

Bearing went out on the fan
Slide out the stove. Unplug the electricity. Remove the back panel with a screwdriver. Then go inside the oven and remove the two Philips head screws holding the fan cover. Then remove the nut holding the fan. Note, it is a left handed nut, so turn it right to loosen it. Pull off the fan. Return to the back and remove the nut and two screws that hold the fan. The fan slides right out. The only problem I had was that the electrical contacts on the new motor were wider than the original. I had to break the plastic so I could separate the wire leads, so that they would fit the new motor. Works like a charm.

The microwave would not turn on or would run with the door open
Other tools that are usefull long needle nose pliers, long thin blade screw driver and small magnetic flashlight. Place the microwave on a work bench and remove the case it cover 3 sides. Place the microwave on a chair so it can stand with the controls up. You are replacing the lower door microswitch. The switch is located behind the control panel in the lower part of the area. The switch is several inches inside this area and your hands will not fit. Take care when moving wires and a couple of sensors. Use the thin blade screwdriver to release a tab holding the switch in place. Do not break this tab. Take the needle nose pliers and remove the switch. Put the wires on the new switch, open the door a short distance so a door lever moves enough to put the microswitch back into the bracket.

Upper Oven convection Fan making bearing failure noises
First remove the internal fan guard, (two Philips Screws). Holding the fan blade and using a nut driver (10mm?) attempt to carefully remove the nut off of the shaft. If it loosens with a counterclockwise rotation, it is a Right Hand thread, Part#: PS11720788. If it loosens clockwise, it is Left Handed and is Part# PS11720787. When the correct fan arrives, check to make sure it matches, then continue with installation.
TURN THE POWER OFF
Following the door removal instructions in the Owners Manual, remove both upper and lower doors. Remove the screws that go into the cabinet on the sides, I believe there are (6). The bottom vent cover is also attached with the bottom screws, so you can remove that and set it aside.

Get some help to assist you with moving the stove out of the wall cavity, it's not heavy, but awkward. I used a small furniture cart, and the second time I used blocking on the cart to raise it to just below the oven and was able to easily slide out/in.
Rotate the oven so you can visualize the back. There are two panels on the back to remove, Starting with the bottom one, remove the screws, (a couple in the middle too) and slide the panel up, (Tabs into a notch on the top of each side of the panel) The second panel comes off the same way, there may be some screws on the side and top you need to be aware of. Once you open the back, the fan that needs to be replaced should be identical. If you have already removed the guard and fan blade from the inside compartment, it should be a simple swap out.
Put it back together in reverse order, put power back on and check to see if it worked. If so, slide it back into the cabinet, be careful the flex conduit is aligned so it doesn't interfere. Second time around it only took me about an hour total and I didn't need assistance.
Fan works, Oven quiet, Happy Wife, Happy Life.

upper fan motor bad
My repair went terrible as I was sent the wrong motor 2 times. My stove sat in the middle of my small kitchen for 2 weeks. Finally the 3rd was the correct one except I didn't have the right nut so I waited another day for that to be sent. Everything working good now, I just hope the bottom fan doesn't go out after this experience.
