Hello Dave, thank you for your post!

From my understanding you are accumulating water under the crisper drawer on your Frigidaire refrigerator. This could be a possible problem with your gasket or drain line. If water line is frozen you may need to perform a manual defrost in order to clear out the line. You need to disconnect power from your refrigerator for at least three to six hours to clear any obstructions. If your gasket is bad then it could cause condensation to develop into your refrigerator. You can also use a dollar bill to test the door gasket. Place a dollar bill in between the door and the body of the freezer. If the dollar bill pulls out with no to little resistance, you may need to replace the door gasket.  A faulty door gasket can allow warm air to enter the compartment and cause frost to buildup. I hope this information is helpful to some degree. –OOS
