Freezer stopped working

I noticed that if I unplugged the refrigerator and plugged it back in a while later it would start working but eventually would stop. I deduced the problem was likely the defrost thermostat. I ordered the thermostat but it was in a difficult place behind the evaporator coil which I could not remove. While I was trying to work it into position my hand pressed against the defrost coil and shattered the glass sheath. I ordered the coil and finally managed to get it and the thermostat installed. The refrigerator seems to work fine now.
