Hello folks. Having some problems that I thought I had solved last week, but yesterday they reared up again. Allow me to give the full back story - about two weeks ago, my LG LMX25981ST refrigerator began to make this click sound every few minutes, and eventually we noticed that the compartments were warm and the ice dispenser was leaking water (ice was melting because of the warm compartment temps). After some googling and youtube watching, I determined that the clicking was a sign of a bad compressor start relay. I pulled the start relay off of my fridge and looked for the replacement part on AppliancePartsPros. The replacement part on there did not resemble the part I pulled off my fridge, so I emailed them and they told me there are several different specific versions of my model fridge, and they needed my serial # to determine the specific part my fridge needed. Eventually the APP guy emailed me with a replacement start relay that looked like the part I pulled off my fridge. Ordered, received within a day, installed, fridge seemed to be working normally again. Measured temps with a digital thermometer & all good. Within a day or two, I started noticing that despite the fridge & freezer seeming to work correctly, there was some kind of growling noise for maybe 3-6 seconds every time I'd close the fridge doors before the compressor or fans (not sure?) would kick on. Might have happened after closing the freezer doors as well but I am not sure. I can say for sure though that the growling noise happened every time after closing the fridge doors, and afterward it sounded normal - steady quiet hum. Anyway, thought this was peculiar & tried a little to diagnose it but couldn't determine a specific issue. Otherwise the fridge was working so I let it go. Fast forward to yesterday and suddenly the freezer nor fridge are cooling anymore. Temps are in the 50s in both compartments. There is no clicking this time so I think the replacement start relay I got is probably fine (unless it caused the aforementioned growling) and maybe there is another problem. I believe the fans are still attempting to push cold(ish) air into the compartments because when I open the doors and manually press the door switches, there seems to be some air moving in from the back of each compartment. I can't fully go through the refrigerator warm flowchart right now because I am not sure I can move the fridge by myself to access the back panel & check on the condenser/condenser fan etc. I will confirm my path on the flowchart within a couple days when I can get help moving the fridge. But if anyone has any early ideas based on what I've said so far as to why my fridge is warm, I'd really appreciate any and all advice. Thanks all! Let me know if I can provide any other info and I'll try to produce it.
