Product review (5 stars): OEM Part 100% perfect!
It will do what it needs to do! FAST ship! REPLACE WITH YOUR DEFROST HEATER JUST TO E SAFE! If you are getting a frozen freezer wall you will need a heater and a defrost thermostat. You can do it yourself for $80!

Defrost your freezer by unplugging it for 24 hours. ->Get a hair dryer and two small towels. -> Get an adjustable wrench and free the plastic wall. -> Defrost all ice and make it dry -> the defrost heater is on the lower opposite side of the cooling coils -> Follow the wires and pull them free. -> snap the heater out of the metal clips -> Install new one -> Do same for thermostat which is visible and out in the open.
