I was trying to replace the light bulb in my oven. When I removed the light bulb cover (made of very thick glass)I dropped it and it broke. My question is..can I use my oven without a light bulb cover over the light bulb ?
The bulb, if it is rated to be used in an oven, will function without a glass cover. The reason for the tempered glass cover is to protect the bulb from damage due to pans and trays and also it keeps it clean from hot liquids. To save yourself the hassle and expense for replacing the bulbs it would be wise to order a replacement cover.
I have had my Bosch oven (mdl HBL 3350UC) 10+ years. The oven Lens cover has broken three times, probably due to high heat used when baking bread. I have replace the lens -$30 each time. I know use the oven with no cover and the bulb works fine. I expected more from Bosch. This is poor engineering. When the cover explodes, glass gets into the food. But you are not aware of this, because there is no loud noise (or I am not sitting next to the oven when this occurs).
