Most of us think that our refrigerator closes completely. But, if it doesn't, your unit may be leaking without you even knowing it. To check the seal of the unit, use the "paper test."
Get a sheet of paper. Open your refrigerator and insert the paper so that half of the paper is on the inside and the other half is on the outside. Close the refrigerator door. If the paper stays in place, it may be OK. Now, gently pull on that paper. If it doesn't move (with a gentle pull), your refrigerator doesn't leak.
Do this for your freezer too.
If it does leak, don't fret too much. You don't need to buy a new unit to fix this problem. Your local home improvement store or the internet are good places to look for a replacement seal.
