All lights burnt out and no charcoal filter found inside

Got online and researched "how to" under the tech specs for my model since I had no paperwork for this unit. The halogen bulbs are extremely difficult to fit into the socket. I tried to purchase 20W bulbs from hardware store... nothing fit, so I gave up and ordered the "GE" bulbs from Parts Select. They still gave me a grief, but finally snapped in... I was surprised I didn't break them in the process. Charcoal filter super easy... just place in the appropriate slot.
