Fridge making a noise

Question

Hello - our GE side by side fridge just started making a steady noise from the back like a clock ticking loudly & slowly. When I opened the door the digital setting was not lit and it appears the fridge will not turn on. The water & ice dispeser doesn't work and all the lights, inside & out flicker as the steady noise is made.
