Bruno for Model Number LFC23760ST Hello! We have a 14 year old LG LFC23760ST with a freezer that is not cooling down enough (I changed out the motherboard about 7 years ago). I cleaned out the coils and checked the compressor, which feels and sounds just fine. All fans appear to be working. No noise or vibration from anything. Minor frost on the back panel of the freezer but was able to brush it off with my hand. I'm thinking of replacing the run capacitor and compressor overload protector. I wanted to confirm part numbers before ordering. Any thoughts on what the issue could be is appreciated. Thank you for your time.
Answer Bruno, You will need to pull the rear wall in the freezer compartment and check to see what the frost pattern looks like on the evaporator coils. If there is heavy frost then this will be a defrost issue in which you will want to test the defrost heater and defrost sensor to make sure that they are good. If they are good then the control board would be faulty and need to be replaced. Read More... Answered by AppliancePartsPros.com | Friday, August 18, 2023
