refrigerator is working fine but continues to leak water into the bottom of refrigerator. I use a towel to soak up water. Removed panel in rear of freezer compartment to see if built up of frost was cause but such was not the case. Called a Sears repairman out and although I wasn't there he apparently used a water bottle to clean out a blockage. The charge was $240.00 dollars three weeks later the same problem is back. Any help would be appreciated.
