Again, not a Q strictly related to electronics but this group is the closest fit.

I have a GE GTS22KCMBRCC (top-freezer) refrigerator. After a couple of months
it developed a minor but annoying habit: when the main compartment door is
closed firmly the freezer door pops open. I don't have a problem cultivating
the habit of closing both doors at once but I've got two absent-minded school
age kids and they're not picking up on this.

How do I go about diagnosing or fixing this?
