LFX25980ST frig is fine, freezer won't freeze.Fan in rear is running, no ice anywhere.

SOURCE: water pooling and freezing inside bottom freezer

I had the same problem with my LRFC25750 and have finally figured out what's happening! The water that is pooling and freezing on the bottom of the freezer is definitely coming from the defrost cycle. It is pooling inside the freezer compartment because the drain inside the back of the freezer intended to carry the defrost water down to the external evaporator tray underneath is blocked with ice. As a result, the defrost water from the coils overflows the collector under the coils and runs down the inside back of the freezer, pools on the bottom, and re-freezes when the cycle is over. this continues until there's so much ice on the bottom that the water from next defrost cycle runs out on the floor. The "easy" solution is to unplug the unit and let it completely melt out (this could take 24-36 hours). I couldn't wait, so I removed the freezer drawers and their tracks and pulled out the back panel inside the freezer -- saw the ice in the collector and blocking the drain and I melted it away with hot water and verified that water could now flow down to the external evaporator tray. Unless you want to do this, I'd say give it a good 24-36 hours for all the ice to melt away. I think it all started when we left the freezer door ajar for a whole day and probably had a lot of frost build-up on the coils. The next defrost cycle was not enough to clear all the frost and things began to build up from there. Once the drain is frozen, though, you're finished -- the defrost heater doesn;t reach down that far and you have to melt it down completely or it will continue to leak forever. I've heard that you can get a drain heater to ensure that the drain never freezes over or at least so that it is sure to clear with each defrost cycle. I'll post an update if I locate one.

the line that gives water to the ice maker, every time the water comes down it lives a drip of water that turns to ice blocking the line, get some hot water and a towel and place the hot wet towel on top of the line intel it melts the ice in side the line. it happens to my frige at list once a year. if that is not the problem the valve that supplies water tho the ice maker needs replacing, it's behind the frige at the bottom, where the line coming from the house meets the frige.

i would take the back freezer panel off and see what kind of frost pattern your coils have.they may be frosted over and the begining of a defrost problem.

replace control board on back of unit there is a six by 10 inch cover on back your panel is in there cost aprox 169.00 dollers also replace bo0th thermisters bottem left of freezer looks like a white bullet the other is in fridge behind shelf trim located beside and underneath where the cold air blows into the fridge.

I would suggest fixing it . You only have 2 parts in the defrost system . A timer , and the defrost heater which comes with the bimetal , pt . # WR51X10031 .Most probable , is the defrost heater . You will need to remove the rear inside freezer panel , and defrost the coils with a hair dryer . After defrosting , 2 screws hold each ( 2 ) heater on , ant the defrost thermostat , just clips onto the top of the coils .
