DOC30M977DM (DA) Samsung Wall Oven - Instructions

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.

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.

I had previously replaced the heating element and heat sensor to the range. The cost of replacing the thermostat was minimal. The key to replacing the thermostat is finding where it is located. Several videos describing the Samsung thermostat showed it housed under the top of the stove. This particular model places the thermostat at the back of the range near the left side. After unplugging the range, and removing the back cover with a Phillips screwdriver, it was easy to locate the thermostat. After unplugging the existing one, and using a very small flathead screwdriver to gently pry the upper and lower clips holding it in place, installation of the new thermostat was a breeze. Removing and replacing did not take more than a couple of minutes. The oven is now heating properly at all temperature settings. I would recommend finding a schematic of the range showing the location of all the parts before beginning the repair.

Pulled off the back panel (6 screws) thermostat was right there removed 2 wires and replaced with new put the panel back on done

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.
