I have a Roper RT21LMXKQ00 Freezer wont freeze

MAKE SURE THE FAN IN THE FREEZER IS RUNNING THATS THE ONLY WAY THE REFRIGERATOR STAYS COLD DO YOU HAVE AN ICEMAKER IF YOU DO IS IT WORKING OR A DEFROST PROBLEM ANY ICE OR FROST BUILD UP IN THE FREEZER
IF YOU SEE IT ON THE WALLS ITS FULL BEHIND THE WALLS OF THE FREEZER

Can you feel air moving or hear the fan running in the freezer section? You said the freezer section is freezing well, but is it freezing really hard?
Regards,Richard

I had the same problem. The frezzer worked but the fridge was not getting cold. What I have learned is that the frezzer make the fridge cold, so if the frezzer is working then something is blocking the cold air to get into the fridge. Most likely ice. The air come in at the bottom of the inside of the fridge next to the frezzer. Pull everything out of the frezzer, then unscrew the plannel that runs along the back and you see if there is ice. If so turn frezzer off and dry out the frezzer. I used hot water.

Go here to one of my tips.

If it was layed down to move and not let sit for a while before using it again it would not work. Somtimes leaving in off and let it settle will straighten it out but not all time. The oil in the compressor get into the cooling lines and blockes the freon. Other than that, check the condenser coil which are near the compressor. They should be warm when the compressor is runnin. If they are not warm there is a compressor or freon problem.

power to the house was shut off for repairs, when power was restored the freezer part of the fridge stopped working but the compressor still runs.

what you are hearing is the overload kicking in and out. which means bad start relay /bad capacitor/low voltage/bad overload/bad compressor.you can buy a 3in1 to eliminate all but the compressor. and the voltage check them first.

I have the sam eproblem but my freezer is very cool, but the fridge wont get cold, it is just chilled, my food still goes bad and the water and soda is room tem..this doesnt make sense!

See if cold air is coming out of the air diffuser top-back freezer side of fridge. A common problem is a bad air diffuser assembly. Sometimes it may freeze closed and break when it tries to cycle. The freezer usually works fine.

if i read the english right, the compressor runs but the freezer fan only runs for a short time. no fan then no cooling. there is a fan stat so that the fan only runs when the evap is down to temp. this may be faulty. also on some hotpoint, the fan switches off when door opened. check door switch operating ok. this may also explain problem with fridge lamp
