Ordered replacement part - this model's light bulb is not screw in - you must purchase the entire assembly. Simple repair - remove the outer cover, remove one screw that holds the assembly in place, remove the supply plug. Attach supply plug to new assembly and reverse the order of operations. The cover did have 2 screws that required a T15 security driver (small hole in end of bit) to remove them. The remaining screws were #2 Phillips head bits.
