Broken Refrigerator

A few days ago I noticed that my refrigerator stopped working completely. I took the back panel off and replaced the overload/start relay thinking that would correct the problem however when I plugged it back in it did not work. I am thinking though highly unlikely that it maybe the compressor. Do you think there is a reset button on this model and how do I check to see if it is the compressor or not?

Also, I noticed that the cooling fan does not work. Does this have anything to do with the relay or is this a separate issue?

Any help would be greatly appreciated
Thank you,

I would look under the control panel for a hole between two mounting screws, that is the defrost timer. With a flat bladed screwdriver, turn the timer till the compressor runs. If so, then replace the defrost timer.
