Replaced overload/relay but may have reversed wiring. (white and red to relay and blue to O/L. I heard the compressor and fan running but when I came back, fan and compressor were dead and the compressor hot to the touch.

Symptoms - Lights work, fan and compressor dead. There is continuity between each pair of pins on the compressor. When unplugged and plugged back in, just a couple of clicks in the control panel.
Did I fry the compressor or the O/L Relay?
Is there a reset process or a linkable fuse?

What are my next few steps?

I will test it in a few days. In the meanwhile, shouldn't the fan be running even though the compressor might be bad? As I mentioned, there's electricity to the lights and ice maker, but the fan is inoperative.
I have learned from reading the posts that there can be many causes for the fan/compressor to fail. The most common cause is a bad relay/overload, but it can also be a thermal fuse (link), an issue with the control panel, thermostat, defrost cuycle, etc. So, in what order should each of these be considered? Thanks for your help.
