Each day I have been finding a pool of water on the floor by my fridge. I am not sure where it is leaking but I thought someone may know what commonly causes a leak and if I can fix it myself. Thanks

Look under the refrigerator. Your drain pan has probably been moved. You could also help by cleaning it out while you have access to it, too. You should see a drain hose for defrost water and the pan has been moved so it is not under the hose. Clean it and put pan back in correct position and this will cure the leak. DrTom4444
