Hi, I’ve got a LG LFC24770ST refrigerator that hasn’t been detected in nearly a year. I’ve actually had two of them, as I’ve moved during the year and purchased the same model for the new house. The usage pattern is clear and obvious to the human eye, with a characteristic repeating pattern of about 50W above the always-on floor, and roughly 18 minutes on and 29 minutes off when it’s idle, such as overnight. This pattern corresponds to the compressor noise. I’ve never gotten a hit on any part of it; not the compressor, not the icemaker, not the defrost cycle.
Is this a fridge that doesn’t have a model in Sense? It’s a less popular model I’m sure, as it doesn’t have in-door water or ice.
