Product review (1 stars): Drat !!!
We have a built in GE Monogram Refrigerator similar to a Sub Zero.. LOL here with this piece of junk. Every 5 years , just like clock work, the heater burns out. It's one of those rubber type heaters that's glued on the defrost pan.  This is a huge tear down taking many, many hours. GE Service refuses to touch it.  A new replacement built in Fridge can cost close to $20,000. Plus the wood cabinet has to be replaced to fit the new refrig.  I used to buy only the heater for under a $100 and did the rebuild my self.  Now one cannot buy only the heater. You have to spend almost $300 for a "kit". That has a bunch of junk that is not needed. Pure scam by ex GE. The biz was sold off to the ?Chinese but still sold under  the GE label for the next umteen years.  Did you ever notice how many American Companies are gone?  Scary.
 Technical note - Heater part # is WR51XO321  . Kit number is WR49X10021  with the heater and a bunch of other stuff.  Anybody know of a Omega heater that might fit?
