Product review (1 stars): No replacement mullion spring available for this model so cannot recommend.
VERY frustrated because the mullion spring broke on this fridge and while you can replace that same part on other similar LG models, they do not sell the mullion spring for this particular model.  The ones for the other ones (MHY62044103 and 106) do not work. I am not even sure that buying the entire mullion (for $80!) will ensure I get a spring, it isn't visible in the parts diagram for Sears parts or anywhere else I looked; nor is there a PN in the parts diagram for the spring for this refrigerator.  Have spent hours on this issue, including buying and trying to install the other two springs, did not work. This was confirmed by a half-hour chat with Sears parts; they were also baffled, but no help.  This alone is a good reason not to buy this, in my opinion, otherwise it's a perfectly ok refrigerator, but mullion springs do break and what the heck to do?
