I have a kenmore model 970-254291 freezer. It runs all the time and has recently stopped freezing new foods. Could this be corrected by recharging the r131a?

If the compressor is running and it still doesn't cool, it is probably leaking freon. If this is a frostless model there are other minor things that can go wrong. This usually shows up on a freezer that has recently been moved or hasn't been used for a time. This is almost never worth fixing as even if you fix it you can't ever completely trust it again. The food inside is usually worth far more than the freezer and most homeowners insurance doesn't cover it anyway.

The problem is in the defrost system.. You have a defrost heater in your freezer that comes on 3 times a day & melts the frost to keep your freezer frost free. That frost turns to water & runs down a drain & eventually goes to a drain pan located under the unit. On these models the hole for the drain is located directly under the evaparator fan. The drain hole is to far from the heater so the water settles & then freezes around the fan blades causing it to stop spinning. Its that fans job to circulate cold air from the freezer to the fridge, so now all the cold air is staying in your freezer. Last I knew they were workin on a solution to this but you need to contact the manufacturer. A temporary fix would be to unplug & then defrost the freezer by taking out the freezer panel & melting all the ice. Boiling water is effective. When you get the ice gone from around the fan you should be able to see the drain hole & be sure water runs freely down the hole. Put it back together then adjust the front legs of the fridge so the whole unit slopes back slightly causing the water to run back to that drain hole without settling.

Hi

Most times this is a bad cold control, but there are other things to check for. Make sure the condenser fan is working and the coils are not covered with dust. A separated heat exchanger ( small capillary tubing soldered to the large suction line ) can separate from one another and make the fridge run too long. - tape tubing back together. A poor working evaporator fan motor could also make the fridge run too long and freeze - replace the fan motor. An inefficient compressor or refrigeration system could make the fridge run too long and freeze - have a service tech check this out. A misaligned control settings, make sure the air damper and cold control have not been bumped and are out of normal settings. Stuck open air diffusers or air dampers are becoming more and more common for allowing too much air to be blown into the fresh food section and freezing things. On all frost free fridge's the freezer temp air is blown into the fresh food section, if you have "easy" to freeze items ( eggs, veggies in water, etc ) in front of or under where the freezer temp air comes out, they could freeze - store them in a different spot. Doors not closing properly making the fridge run too long is something else to check for.

Please do rate the solution as FixYa and revert for further assistance.

sounds like your loosing freon.

look under your refridgerator and see if there is alot of dust on the coils. Whenever food starts freezing in my fridge I vacuum the coils and the problem goes away.
