I Agee with Ray - You can gain access to the lamp holder by removing the outter wrapper - unplug the power before you start

not possible

That is referring to the under the microwave light that shines down on your stove. You have full brightness, half the brightness, or the light will be off.

HI, there is a inline fuse located inside the microwave ion the power supply board. check for continuity. replace the fuse if necessary. if the fuse is OK, replace the power supply board.

Unfortunately, there is a good chance that when the bulb shorted out, it damaged the control board. The only way to know for sure is to do some electrical testing with a volt/ohm meter and the wiring diagram located within the appliance. The relays for the fan and the lights are part of the board. The power should always be disconnected when these bulbs are replaced or the board will be damaged. We would have an appliance repair person take a look to see what the deal is with the microwave.

I HAVE KENMORE 665/61629 LIGHT STAYS ON. AND DO NOT COOKS. AND THE FAN DOES NOT WORK.

The problem is most likely in the door latch circuitry. This is an expensive repair. Consider replacing the unit. If the door latch is not repaired correctly, very dangerous microwave energy can be released. This is not a do-it-yourself project. New ovens are very reasonable.

We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

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 operation, too. The lights and fan can be inoperable or stuck on too.
