NV51K7770DS Samsung Wall Oven - Overview

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.

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.

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.
