Craig S Bozeman , MT June 11, 2017 Appliance: LG Refrigerator LFC25770ST Lg Refrigerator Lfc25770st / Ast2lga: Lg refrigerator relay overload clicked on and off every minute while fridge was still cooling. How to replace Thermistor Assembly. I feared the compressor might be bad, but wanted to start with these smaller part replacements. It was easy to remove the relay and overload. I asked Appliancepartspro.com chat to suggest the part for me based on model number. Within a minute, chat was able to suggest the parts, made by LG and which came as a combo package for around $100. http://www.appliancepartspros.com/lg-thermistor-assembly-local-cls30820101-ap5953061.html#ixzz4jHZSjJVP . The parts looked very similar to what I had. I searched a couple other sites and found some options which were about $50 cheaper, but didn't look the same.. which worried me enough. Plus this Appliancepartspro.com site had helped me with a dryer part repair about 6 months ago. So I opted to go with them. Part was shipped next day, and arrived fed ex the very next day. Popped them on the fridge easy, and no click. But then fridge did not cool, and compressor was not turning on. Although the fan was running. After waiting a day, I took the parts off to check the ohm reading on the compressor tines, and sensed as I was removing them, that I may not have connected one of the wires effectively. The ohm readings were normal for a good compressor. Upon reinstalling the new parts, relay and overload, I made sure to get each wire connected securely on its respective tab.. and after plugging in the power this time, the compressor turned on immediately and quietly.. the fridge began to cool. All is back to normal. 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
