For model number MS2040ARSE
PartSelect logo
Hello Katie, thank you for contacting us. According to our research, we are providing you with instructions that will help you set the TCP code. 1- Press the clear button. 2- Press the TrueCookPlus button twice. 3- If you want less cooking time when you enter a TrueCookPlus code, press 1. This will decrease the time by 6%. 4- If you want more cooking time when you enter a TrueCookPlus code: Press 3 for 3% more cooking time. Press 4 for 6% more cooking time. Press 5 for 9% more cooking time. 5- Press 2 to reset TrueCookPlus to the factory default time. 6- Press the Start button. l = shorter (6%) 2 = normal (default) 3, 4, or 5 = longer (3%, 6%, 9%). We hope this helps!

Motor Burned Out On Turntable
My 8 year old daughter cleaned the inside of the microwave with enough water to rival a tsunami. Resulted in a clean microwave with a fried out motor that no longer revolved. Part came quickly. Took cover and bottom off to get to the part. One screw held it on and a plug. Removed those, put on new part and she was good to go. No trip to home depot today.

Magnitron failed
Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.
