Our CSD 2124AR Magic Chef refrigerator is leaking water from underneath. It is NOT connected to a water supply for the ice maker. Any ideas on where to start looking for its source?

This is condensate water from the self defrosting system. There is supposed to be a plactic pan under the ref to catch the water. Make sure the hose is directed into the pan. If the unit was moved or cleaned under the unit the hose could have been misplaced out of the catch pan.
