The mother board likely got shock when it was plugged back in. Try unplugging it for two minutes and then see if it runs. These boards do not come back very often though. It is #801 on the look up. Most local parts stores will carry this item and you will not have to wait for an online order.

I did as you instructed and the fridge is still clicking from the motherboard area after I took off the panel. I can clearly see this is the area so should I just go and purchase a new one and hook the new one back up.
