Product review (5 stars): Original Equipment part, not an after market copy
Looks  just like the original.  You may want to order the evaporator fan as well, It was a bit of a hassle to replace these parts in the back of the lower freezer, and the wire that feeds power to the heater broke and arced burned both sides of the connection.  The wires that feed the defrost heater are part of the evaporator fan.  The Longest part of the repair is getting all the ice melted off the evaporator core.
