Product review (5 stars): Refrigerator was freezing everything, this part fixed the problem!!
My refrigerator was freezing everything on the refrigerator and freezer sides.  It started at the top shelve and froze the milk solid. It also froze the water filter and leaked water all over the fridge which also eventually froze. I thought maybe the temperature thermostat was bad but upon further troubleshooting found that no matter what temperature the refrigerator was, there was always come air coming through back upper corner where this part is.  It was also making alot of clicking type noises.

After replacing this part, I found that this new valve would close and open regulating the temperature of the refrigerator and making everything the right temperature again. The way I tested it was too turn the freezer side thermostat to a colder setting so that it would turn the compressor and evaporator fan on creating air flow. I then placed my hand over this valve in the back corner. I could feel air blowing through it. I then adjusted the temperature knob on the refrigerator side to try warmer settings to try and make the cold air flow stop. I could never get the valve to close therefore always blew cold air through no matter what setting I had the thermostat to.  The new part closes and opens with command from the thermostat like it's supposed too.

Most people with the other reviews had a problem with there fridge being too warm but there valve must have failed closed therefore not allowing any color air through. Mine was opposite and failed open.

As for the installation, like everyone else says, that glue is strong and sticky.  I used a 1/4 inch chisel and flat blade screwdriver to pry the glue and eventually work the old part loose.  It seems to work fairly well. I would recommend a 1/4" socket driver to unscrew the screws securing the plastic covers as it's a tight fit for sockets. Overall not a bad repair and it's nice to have the fridge working as is supposed again.
