I ordered a bulb which wasn't listed for my oven but it was correct. In order to replace the bulb you must take the back panel off the oven which had 14 screws and then take the lamp socket out of the back in order to replace bulb. It took the better part of an hour but was worth it the light comes on while the oven is on so you can check the status of the food without it you are just guessing or had to remove the food to check and that causes a cool down thus taking longer to prepare the food. It works great well worth the effort.
