Fridge is 1 year old. Yesterday, I was doing some yearly maintenance and I unplugged it without first turning off the temperature control (not sure if that matters). Then when I plugged it back in there was a spark at the outlet. The compressor started making a loud humming/buzzing, almost like it was trying to turn over, and was very hot. After 30 mins or so the sound went away and the compressor isn't hot anymore. Did I damage the compressor? Or is it normal for it to be really hot for a short period of time?
