Hello John, thank you for contacting us. To change the oven light, follow these steps: 1. Tilt the broiler heater down. To do this, turn the circular nut on the support counterclockwise while holding the broiler heater. The broiler heater should loosen and tilt down. 2. Remove the glass cover.  3. Remove the halogen bulb cover.  4. Replace the halogen bulb. 5. When done, replace the halogen bulb cover, replace the glass cover, and then follow Step 1 above in reverse order to return the broiler to its correct position. We hope this helps, good luck with this repair!
