Kenmore Microwave Model 721.67601790 lights don't... The two light bulbs on the bottom side

Question

The two light bulbs on the bottom side (underneath) of my 900 watt microwave will not work. The bulbs are fine.....but they will not light up. The fan works, the light inside works, the turntable works,everything about the microwave works EXCEPT these two bulbs. This is crazy.
