Does the rear oven light assembly come with a light bulb ?
Answer Hello Donna! Yes, the rear oven light assy W10009930 includes the bulb. Thanks!
While I order/replace the interior light assembly, will the heavy glass cover provide sufficient protection against heat loss so the oven can be operated safely?
Answer James, Yes, the glass globe and the receptacle housing will provide enough protection from possible heat loss in the oven cavity for the oven to operate properly. You do need to insure that there is no damage to the housing, or the insulation when installing the assembly. You also want to apply a thin coat of vegetable oil or "Vaseline" to the threads of the glass globe, and don't over tighten, the glass has a tendency to "stick" or seize to the receptacle, making it hard to remove in the future.
