my microwave did not have a fuse. are you sure it is not a switch?

The main fuse is inside the cabinet near where the power cord enters. When everything goes dead all of a sudden, 99.9% of the time it's the fuse.

Hi Ben,
This has got to be an intermittent power to the control PCB problem. The control board asking to set the clock means that the CPU has been reset by losing power. First, make sure that the problem is not the outlet by plugging in a small lamp or digital clock to see if it works intermittently or resets. Leave it plugged in for at least 24 hours.
(If using a lamp, put in a small 20 watt light bulb or CFL).
It could also be a bad connection to or at the fuse holder in the microwave oven. If all of the wiring and connections look good, it's most likely a bad connection on the control PCB probably around the transformer on the board. Be careful.......

Unplug, remove top, look under keypad, follow wires to circuit board, look for a silver rectangular capacitor, "may be under a plastic flap" discharge capacitor with a screwdriver across the 2 points, look for a small fuse near by in clips, remove and replace with same current rating, assemble before test because lethal voltages present when powered.

That model should be KHMS2050SS0, KHMS2050SS1, or KHMS2050SS2, I think.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid with a one year guarantee.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan, cooling fan, turntable, and/or inside light operation, too.
