Hello,
I own an LG Refrigerator model LFXS30796S/00 whose freezing and cooling has stopped, but other functions (light, etc.) continue functioning. The unit was purchased in 2018 and the freezer drawer has been left open THREE times. The 3rd time, the unit did not return to normal function after being left open for the coils to thaw. After reading posts on this incredibly helpful forum, I opened the right door and pressed/held the Refrigerator & Ice Plus buttons on the front panel for 5 secs. The dreaded FF error code appeared indicating a bad Evaporator Fan Motor. I replaced the Evaporator Fan Motor (EAU63103204) and the Icemaker fan motor (EAU63103205) because I was already in there. I also went ahead and vacuumed the dust that had accumulated on the condenser coils on the rear of the unit (not much dust).
I cleared the FF error in two ways. First, I opened the left door and pressed/held the Refrigerator & Ice Plus buttons on the front panel for 5 secs. After 15min or so, the dreaded FF error code return along with a non-functioning refrigerator (no cold air). Secondly, I reset FF error code again by using the method described on this forum. "On the main control board behind the machine is a reset button. Push this button, wait 2 seconds, no more and push it again." The FF error code returned which likely meant a bad main board. I have ordered a replacement board (EBR83806906).
On CON7 on the main control board, I measured the voltage between the blue and the red wire. It was less than is less than 9 VDC which means replace the main board. My question is, am I on the right track? Also, can you provide a Technical Service Manual for my LG refrigerator (LFXS30796S/00)? I would like to trace my main board and determine what burned out. Can you provide a main board schematic, please? Any idea where this design flaw lays on the main pcb? Thank you!
