My Kenmore microwave 721.62629200 was operating normally when I heard a short loud buzz, followed immediately by the oven shutting down. Now the oven will not go on at all. No lights on the display, no light when door is opened. Not sure how old the oven is since we moved in last summer.

It appears your magneto or power supply has failed in this instance.

For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.
