Ice forms on the bottom shelf of the frost free freezer. We have no ice maker. What could be wrong? It's seven years old. It's a Whirlpool
I expect that when you check - the drain tube behind the inside back wall of the freezer compartment is clogged with debris and / or ice.
First, disconnect the the fridge from power at the plug.
Inspect the evaporator pan under the fridge. It is probably dry. If not, empty it and replace it.
Gather some towels & rags, a wet vac if you have one and a blow dryer to defrost and soak up / pick up melting ice. Also get a flexible piece of wire (coat hanger will do), turkey baster and a pail or container. A small amount of bleach will be needed, too.
You'll have to empty the freezer compartment of food and remove the back panel to gain access to the pan and drain. Some freezers have a plastic shelf pan that covers and is screwed to the freezer floor - if yours does, you should remove it, too. Keep clear of the coil, heater and controls that are protected by the panel. Plan on two - three hours to do the work, and an additional 2+ hours for the freezer to get cold again if all goes well. It will take much longer if you do not accelerate the defrost process (chipping, use of a blow dryer, etc.). If you can store food in a neighbor's freezer - that will be ideal.
Next, defrost the freezer. CAREFULLY chip away ice on the floor of the freezer. Do no chip in the area that was behind the back panel. Direct the hot air from the blow dryer at the ice in this area instead. Use towels and wet vac to pick up the water. Fill the container with hot water, and fill the turkey baster with the hot water and discharge the hot water at the ice / drain opening to speed the defrost process. Try to keep splashing to a minimum. Remove the blow dryer from this area when using hot water to melt the ice. Once the ice ice clear, check the evaporator pan again. Carefully remove it. If no water is present, the tube is still blocked. Replace the pan and continue to melt ice in the drain and check again. Repeat as needed. it is possible that a spider has taken up residence in the drain pipe - or there is some mold growing inside it. Use the coat hanger to gently "snake" down the tube to clear any obstruction. Once water begins appearing in the evaporator pan, empty it again and replace.
Mix up 4 ounces or so of water and 1 once of bleach and draw into the turkey baster. Place the opening as close to the drain opening as possible and gently squeeze the mixture into the drain. The mixture will kill any mold, spider, etc. that has been growing in the tube.
Almost done, CAREFULLY remove the evaporator pan again after allowing enough time for the tube to drain and empty in sink. This is a bleach mixture so be extra careful not to spill anywhere that bleach will cause damage.
Lastly, clean up with disposable rags (don't ruin towels picking up the bleach mixture) and reassemble back panel and floor pan. Restock freezer and plug the fridge back into outlet.
I hope this helps & good luck. Please rate my replay. Thank you.
