GE Select Refrigerator is Clicking

Just about 20min ago the back of my refrigerator started clicking over and over and hasn’t stopped. there also seems to be a bubble sound when it clicks as though its trying to start something. The lights inside dim slightly on each click as well…

Help pls…

Thank you for your time.

Could the issue be with a defrost timer? if so… where is it?

I have read and was told that it could be and that i could locate it and give it a turn with a screw driver.

I have been looking for the thing for the whole day and i cant find it… pls help.

Is this possible?

Thank you!

No, it has nothing to do with the defrost system.

There is no a such part in your refrigerator. The defrost cycle is operated by the main control board.
