Easily, Removed the oven with help of my grandson, this model is quite heavy. Open the back cover panel, removed the old blower. replaced with the new blower, covered with the back protective panel. About one hour because some screws much harder to reach.

EASY. FOLLOWED THE YOUTUBE INSTRUCTIONS ON THE WEBSITE.

Ordered a new motor. Removed the outside trim of the oven-microwave combo. 2 screws at the bottom of the trim. Removed the screws that held the combination micro and oven unit in place. Removed the top and bottom black plastic grill of the microwave. 3 screws each. Pulled the entire unit out about 1 inch exposing the screws at each side of the microwave that hold it in place.
Snapped off the top control panel which exposed the wiring connecting the control panel.
Unplugged a couple of wire harness units to free the control panel.
Be sure to label the units to know which goes where during reassembly.
Remove the microwave unit from the housing and place it on its side.
Remove the metal plate that houses the motor. 4 screws hold the motor in place. Disconnect the 2 wires from the old motor and you are ready to install the new motor. Be sure to TURN OFF THE POWER to the unit at the breaker box and remove the turntable from inside the microwave.

I turn off the power in the breaker box and then unscrew the part and replace it with the new one

Pulled the stove out, unscrewed the back and plugged the new thermostat in. Screwed the back back on

Unplugged old element unit and plugged in new element. Took two needle nose pliers and a flexible body. Took about 5 minutes. Works fine. Anybody can do it. Make sure power is off at the box.

The tech said he used No 2 Phillip's. Once I took the door off and removed the racks I quickly learned a Phillips was not going to work. I am now the proud owner of a Kobslt star and square ratchet screwdriver.

I looked up the problem and determined I needed to replace the limit switch which is inside the back panel. As a 78 year old woman who isn't afraid to tackle these problems I found this easier than most. Just be sure to disconnect the electrical connection if you don't have long enough length to pull oven from the wall cabinet. I won't put any sheet pans in the oven next time I self clean it.

1) Removed the trim pieces (2 screws). 2) removed the 2 screws holding the oven in the wall. 3) Slid the oven out of the wall cabinet 4) removed the back panel of the oven ( 10 screws. 5.) removed the old thermostat (2 nuts) 6.). Installed the new thermostat and reversed steps 4-1

1. Disconnect AC power 2. Remove back with several sheet metal screws. 3. Remove wires from Limit Thermostat. 4. Check Limit Thermostat continuity -- if open then Limit Thermostat is faulty. 5. Remove Limit Thermostat with two screws. 6. Install new thermostat

Since there is multiple glass panels with several brackets, screws and insulation within the oven door I strongly suggest to take photos at each step using your smart phone. Do not attempt to remove all the components at once. Bracket positions, screw locations and glass orientation is necessary. This is the best advice I have to make this a quick and very easy job.

Removed locking device

I took the new tray out of the box and placed it in the microwave oven.. No tools needed.

Ordering the part online was easy. It arrived in a timely manner. I found a terrific video online showing how to install the terminal. It was so easy. Thank you for the great instructional video.

After we put the latch pins in, the door was easily lifted off. We placed the door on the table and unscrewed the trim pieces. The new trim pieces went into place after we cleaned the door. We slipped the door back on the oven and removed the hinge pins.
