Lights not working
 

I have Whirlpool Refrig mod. G565hexn and the refrig lite went out and also the led lite for temp controller, and also when you open the refrig door it is making a buzzing noise under the refrig, the freezer side is working good with no problems , what could make this noise and stop the lites from coming on , also I changed the bulb

Model no. GS5SHEXNB
 

I gave wrong mod. no.
