Water is leaking from the dispenser area as well as the bottom of the freezer door of frigidaire frs20zrg

the water holder on the right side (refrigerator part) needs to be replaced. It is clear and located on the back about 1/3 of the way up.

Check the connection to your water filter and check to see if the door seals completely when closed. To do this gently rub colord washing up liquid on the sels and close the door, then open it and look to see of the seal left a soapy mark on the frame of the fridge. it is often the case that the door can warp and this leads to the ice crystals and subsequent melt water around the area that is not sealing.

without a model number to check out what else might be in that area of the door i'd say a piece of tubing from the water source is leaking, or you are getting ice melt from inside somehow making it out through that panel now. i believe the water for the door comes in through the bottom of the freezer door and works its way up to the dispenser area, the solenoid for the water inlet is behind the fridge near the bottom (you'll see the water tubing).
more likely somethings just not fitted or aligned properly and waters making it out someplace it shouldn't.
best of luck to ya

Either the drain hose is plugged up with ice and not dripping into evaporator tray, or the defrost unit needs to be replaced.

the drain in the freezer compartment is frozen up you can remove all items from lower freezer and remove access panel on back of freezer compartment pick the ice out of the drain hole with a small screwdriver DO NOT USE SCREWDRIVER AROUND THE ALUMINUM COILS! once all ice is gone that you can see use hairdryer to blow into hole on medium heat. once it looks like it is gone take a small 1/4 plastic tubing and push down the hole to try to clear obstructions then run hot water down hole. if it still doesnt drain take rear access panel off of compressor area (back of refrig) look for drain hose and remove clamp take off and clean u might try this first. but you will have to remove ice from drain.

the water line for the water disp runs in a chase that goes up thru the bottom hinge of the refrig door. SO DONT PULL YOUR DOOR APART! you can order a new water line thru frigidaire and replace the part by removing the water dispenser housing on the door and pulling the line thru the door then inst the new line in reverse. if it looks like too big a job then get a reputable company to inst it for you. 

You have a bad diode on the water valve connection frigidaire has a kit for this fix..
