Product review (5 stars): At least it got the doors to seal better. Will have to research it some more to ...
Ordered this part to try and fix a Whirlpool refrigerator on which a wheel on one of the front rollers had broke.  With that broken wheel, the refrigerator was cocked enought that both the freezer and refrigerator doors would not seal quite right!  After emptying the whole refrigerator, lifting the front of the frig about 3-4 inches and placing 2 pieces of wood under it to hold the frig up, I attempted to replace the roller.  However, I could not figure out how to remove the pin that holds the roller in place!  I could not see the one end of the pin.  It seemed to have a head on it and it was between the frig side and where the roller mounts, so there was no clearance to pull it out!  Not sure, but might have to drop the bottom pan down far enough to clear the frig side.  I did not want to attempt that at the time, so ended up propping it up with a thin piece of wood.  At least it got the doors to seal better.  Will have to research it some more to see if what needs to be done.  The new roller would have worked fine had I been able to use it!
