Question about Kenmore 62702 Microwave Oven
The microwave seems to be working properly for 10-15 seconds and then has a power failure. The timer display blanks out and then comes back on in a few seconds. I can then start the microwave again, but it will only run for another 10-15 seconds or so before quitting again. When I run the microwave with the surface light on, the light remains on the entire time, so I know the house hold circuit is not shorting out.

F-9 error code indicates a defective control board, inverter or line voltage too high. f the microwave runs for about 7 seconds with a ticking sound..then stops and shows "F-9", it is the magnetron that has failed. The fact that the unit starts and runs with the TICKING SOUND means the control board is sending signal to inverter board and the inverter board is sending signal to magnetron. Magnetron is covered by full 5 year warranty, inverter board is only 3 years.

Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.
Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.

"d" may mean demo mode. The first thing to try is a "hard reset". Unplug it from the power outlet for 10 minutes, plug it back in, set the clock, then try again.
