give me ideas?

My refrig Whirlpool model #10657989700 was chilling and then stop I had sears look at and they said it was the thermostat. I bought the part was going to put in myself but I made mistake and touch the ground to wrong pole and got a pop. I went ahead and installed that thermostat but refrig did not come back on. I purchased a second thermostat and installed correctly but frig still did not work is there a reset or fuse or some other thing I need to look at?
