Error code 1F indicates an abnormality of the BLDC fan motor for ice making, caused by a poor BLDC motor connection, DriveIC, and TR. This information can be found in the service manual on pg. 32 of the service manual:
http://136.166.4.200/contents/Fridge/LFX25960/LFX25960_Service_Manual.pdfFrom the research I've done it sounds like it is usually a bad fan motor that causes this condition. This will prevent the icemaker from working. I'm not sure if it will affect the defrost cycle. If you turn off the icemaker, then either pull the plug for a few seconds or turn off the circuit breaker for a few seconds, the front panel will light up and stay lit. Then you need to call for service.
PS: I'm finding out that this refrigerator is more problems than it's worth. First it was the drawer glides breaking, then a balky ice maker, now the fan motor. From what I found out on the internet, I'm not the only one with these problems. I've only bought two LG products, the refrigerator and a small LCD HDTV, but I'm not happy with either one of them. In my opinion LG is an inferior product.
Hope this helps someone.
