Gary-I have the same problem.My fridge is about the same age.One thing I did think of.Do you put big bottles on the inside door?I think that perhaps the bottles push against the crisper at the bottom, and because the door seal may be older and weaker;the door is ever so slightly pushed open.I gdon't get it all the time.You can put the temperature control up, and it freezes the water at the bottom, but everything else gets colder in the fridge. I am still waiting for an answer, so Good Luck.
