Starter Overload

Heard the snap of a short circuit followed by a burning smell around the refrigerator. Pulled it out, unplugged it and removed the back panel with a nut driver. Plugged it back in and when the compressor kicked on I saw sparks and some smoke at the relay. Unplugged and ordered new relay and the associated run capacitor in case it was also bad.
Removed the holding clip and the relay with capacitor easily came out with two wires attached. Removing the wires was done by prying with needle nose pliers with some difficulty.
Inserting the wires into the new relay was also difficult. If the position isn't just right it does not snap in. Once it is positioned correctly it makes a positive connection with not much effort.
Reassembled the capacitor, plugged unit into compressor, added retaining clip and plugged in refrigerator.
Compressor started up correctly. Note that as the refrigerator cools the compressor will shut off for long periods of time. This is normal.
