I have a similiar problem with my LG refrigerator. The freezer settings get stuck on 6 and 7, while the refrigerator side is showing nothing. Pushing the buttons to adjust the temperature does nothing. The whole time, my food is getting spoiled.

    We have the exact same issue. The only fix we have found is to unplug the refrigerator for 8 hours. Not convenient I realize, but it works. Our problem is we have had service people out to check it out, but it works fine when they get here and they tell us they can't tell us what's wrong if it is working fine. And it generally happens on the weekend when these guys are not working or the rates are ridiculously expensive, so the only option is to unplug, move our food to our upright freezer, and wait it out.

    I had the same problem. The manual showed how to remove the drawer. I removed the drawer, ice maker and the rear inside panel and found that the freezer fan and cooling coils where frozen solid. I used a hair dryer and my shop vac and melted all the ice to end the problem . The temperature read outs are normal again.

Hello, my LG Refrigerator (lmx28988st) is acting up. The fridge stays cold, but the freezer won't freeze (its stays around 45F). It has the french doors for the fridge, 2 drawers for bottom freezer.

Have you confirmed the freezer door switch is functional? If this switch fails to detect the door is shut (you may or may not get an alarm), the unit will fail to cool properly. Meaning the actuator will not allow cold air to be diverted to the freezer.

If all else fails, you may try contacting LG directly by clicking here:

Icemaker doesn't work

If the ice maker is not filling, you will need to replace the "water inlet valve" on the back of the unit. Here is the part you need to order.

Lg side by side refridgerator ice maker

you can adjust the control for the freezer side to a colder setting think of the freezer control as a door warmer setting door open farther colder setting door farther closed the fridge control is electric that runs the compresser can turn fridge down to creat more cooling freezer or set freezer to colder setting it is a balancing
act have actually closed freezer control to coldest setting and had items freeze in the fridge side where air from freezer first enters fridge a lower temp in freezer should help ice production

My GE profile side by side refrigerator's temperature is not staying where I put it. It keeps popping to 31 degrees when I set it for 37 degrees. My food is freezing !!

It may need to defrost. Shut it off for 4-5 hours to let any accumulated ice to defrost and see what happens.

There also is a control that directs more cooling to the refridgerator or the freezer compartment. It may need to be readjusted. It will take 24 hours to stabilize.

Touch Temp Controls

If the touch control doesn't respond then it's most likely bad. They don't normally act up, they either work or they don't.
