Control Panel Light is out.

It's very easy.. Pull your oven from wall and take screws from back of panel.. You will see control board after removing cover panel. Take screws from control board or could be attached with clips. Pull wires with plug ends off of board and reinstall on new board. (In same places of course). Put control board back in and put cover panel back in and screw down and plug back in. Make sure all power is unplugged before servicing.

Here's a repeat of Kai's instructions so you don't have to scroll down. I just replaced mine and it was a snap. Just a few Phillips screws and a few tugs. No need to pull the unit completely out as you can access the bulb after it's about half way. No need to disconnect any wiring harness except pulling the bulb out of its socket. I used the 10w (G4 12V) replacement bulb from Home Depot at $6. The light is a bit brighter but there've been no problems with fuses.

1) Turn off power to the unit
2) Open the lower oven door
3) Remove the side trim screws and pull the trims down and out.
4) Remove 2 screws on the sides of the control panel.
5) Open the Microwave door. Remove the 3 screws on the Air Vent Plastic Cover on top of the microwave. You can then remove the Air Vent Cover by pushing the control panel up and pull out slightly at the bottom.
6) Remove the 4 screws on the Air Vent Plastic Cover on top of the lower oven and remove the Air Vent Cover. (You may have to remove the left under side bracket of the Microwave door temporarily just for the Air Vent Cover to clear the screw of the bracket. Re-secure the side bracket of the Microwave door panel as the front panel may fall)
7) Remove the 2 screws which held the Microwave unit in place behind the Air Vent Cover on step 6.
8) Wiggle the Microwave unit out about half way to expose the light bulb unit on top center
9) Wiring to the Control Panel will prevent you from pulling the Microwave unit out any further. And you don't want to do that as the unit may fall. Space is cramped, but working carefully with pliers you should be able to release the springs which held down the light bulb unit and change the bulb.

An oven thermostat is a switch that opens and closes in response to the temperature it senses. It is typically found in the control panel, where a liquid-filled temperature-sensing bulb senses and maintains the internal oven temperature by cycling heat on and off.
Before repairs or testing can begin you must disconnect the electricity at the fuse panel, at the circuit breaker panel, or by pulling the plug. Make sure the power is off before proceeding. A jolt from 220 volts can be fatal, use caution!

1. Access the oven thermostat, which is located in different places depending on the make and model: On freestanding ranges, access the thermostat by removing the screws that hold the back panel in place at both ends.On models with front-loading controls, remove the panel and tilt it for access. Be careful not to let the wires disconnect from their components. Some built-in models have a removable back splash. Lift the backsplash, rest it on the cook top and remove the screws from the back splash, which holds the rear panel. On wall ovens or eye-level ranges, access the control panel by opening the door and removing the screws that secure it. The screws may be under the exhaust hood or below the control panel. If the control panel is hinged, simply tilt it towards you. On some models both the rear and front control panels must be removed. The screws may be found on the trim and occasionally the trim must be removed.
2. When testing the thermostat switch contacts for continuity, refer to the wiring diagram and remove only those wires being tested - and only one pair at a time. Test switch contact terminals as per your wiring diagram. If the switch lacks continuity at any of the contact terminal points then the entire thermostat switch needs to be replaced.
3. Adjusting the thermostat: Test the oven temperature by placing the tester in the oven's center and leaving it for 30 minutes at 350 degrees. Record the minimum and maximum temperatures of three cycles, then add those figures together, divide the result by six and you have the oven's average temperature. If the average temperature is more than 25 degrees off, try calibrating the thermostat by following your appliance manual instructions for thermostat calibration. Normally, thermostats are calibrated by pulling the oven's thermostat knob off, turning the knob over and adjusting the calibration ring on the back. If your oven doesn't have a calibration ring you may need to replace the thermostat.
4. To remove the thermostat: Disconnect the capillary tube and push it through the back oven wall, being careful not to break the flammable capillary tube wire.
5. Remove the screws that secure the thermostat to the control panel and gently pull the thermostat out, leaving the wires in place.
6. To install a new thermostat, reverse the disassembly procedure, transferring the wires individually from the old unit to the new.

This worked like a charm ... actually it's easier than you might think. Just a few screws and a few tugs. Give it a shot.. I found a 10W (G4 style ... you'll see the difference when you get to the store) replacement bulb at Home Depot for $6:

Hi Dagmail543
You can only access the old unit by removing it from the back of the panel.Some screws and clips (base at the two sides) The clock is usually secured with screws. - remove old unit replace with new - no peel or scrape usually necessary

Regards

Shut the breaker off to the oven first. Frame around mircowave is a snapped on front. Removing allows access to two screws under control panal. Must actually pull entire unit out about 9 inches to access top of control area to remove access panel. Once front control panel is removed and top is opened, easy access to what you need to get to. Carefully write down color coding of wires before removing any of them. Remove old power supply board and display and reconnect. Reverse process. A bit of work but if you watch the disassembly process carefully, pretty easy.

Here is a simpler method from the same website mentioned in solution #1:
1) Turn off power to the unit
2) Open the lower oven door
3) Remove the side trim screws and pull the trims down and out.
4) Remove 2 screws on the sides of the control panel.
5) Open the Microwave door. Remove the 3 screws on the Air Vent Plastic Cover on top of the microwave. You can then remove the Air Vent Cover by pushing the control panel up and pull out slightly at the bottom.
6) Remove the 4 screws on the Air Vent Plastic Cover on top of the lower oven and remove the Air Vent Cover. (You may have to remove the left under side bracket of the Microwave door temporarily just for the Air Vent Cover to clear the screw of the bracket. Re-secure the side bracket of the Microwave door panel as the front panel may fall)
7) Remove the 2 screws which held the Microwave unit in place behind the Air Vent Cover on step 6.
8) Wiggle the Microwave unit out about half way to expose the light bulb unit on top center
9) Wiring to the Control Panel will prevent you from pulling the Microwave unit out any further. And you don't want to do that as the unit may fall. Space is cramped, but working carefully with pliers you should be able to release the springs which held down the light bulb unit and change the bulb.

By the way, the bulb is Osram 64405S. It's available online for about $2.00 plus shipping.

You have to slide the oven partially out of the wall and there is a metal cover panel on top...remove it and you will be able to access the wiring panels, etc.

why are you trying to remove the panel are you talkin about the control panel
