Question about LG LRBN20510WW Bottom Freezer Refrigerator

Freezer working fine, but Refrigerator no longer cooling

The top half just stopped working right, about a day ago. The bottom half is working just fine. I've tried clearing thing away from the Multi-Flow vents, cleaning the rear vents, and unplugging the unit for a few minutes, hoping to "restart" the system. Any ideas?

Re: Freezer working fine, but Refrigerator no longer...

Sounds like there's an airflow problem to the top section. Things that cause no cold air to the top fridge section are... frozen up coils completely blocking most of air flow (defrost cycle not working), evap fan not working to blow air up to fridge, air control dampers in fridge closed or not working properly, or frozen air ducts supply/return. Pull the whole drawer out the bottom and take the rear inside back off to expose the coils. If they are frozen solid the defrost t-stat or defrost timer could be bad (heat element not usually bad). If there is a nice white frost all over evenly then that's OK. Check that the fan is running when the compressor is running to blow the air up and that there are no blocked air ducts, etc. If all that is good, check if you can feel good air flow from the upper vents with the lower door closed (that shows there is no blockage and the fan is running).

Refrigerator stopped cooling 2 days ago. Freezer works fine. What is broken? Appliance is four years old. Replaced compressor almost exactly 1 year ago.

Check the fan in the freezer and be sure it's working, isn't blocked by product or isn't clogged with ice. If this fan isn't working the refrigerator section won't cool properly.

Refrigerator will not get cold, but freezer works

Make sure your fan is working ,its located behind the freezers back wall. If it is working the vent from the freezer down to the refrigerator may be blocked (usually with ice).With out a fan you have no circulation but your freezer may look likes its working,it may last 3 days.Also if you can move everything out unplug it turn it off w/ doors open untill all traces of ice are gone this will free up any clogged tubes. Good luck.

Regrigerator stopped, now freezer too.

It is due to the defrost timer is not working. Once it is replaced, you should be good for another year. The information is given by the repairman. I have this replaced two days ago. The MayTag part number is: 61005988.

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.
  • possible causes:
  1. bad defrost timer
  2. bad defrost heater (in freezer)
  3. bad thermo switch in freezer
If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.
  • if you already checked this and think it is a different problem then let me know, i will help you figure it out.

Bottom freezer not working

Hi, sorry I do not have any advice to offer. We have the same model. Three weeks ago the red light came on and freezer stopped working. Last week the fridge packed up. We may have been unlucky but I thought it might be worth mentioning incase they were related and your fridge gave up as well.
