Genji for Model Number LG LFX25991st Where on the LG LFX25991ST is this sensor located in the refrigerator compartment? Is it behind the LED light assembly at the top of the inside of the refrigerator cabinet? Is there a way to test this part without cutting it out of the refrigerator first? How should a new replacement part be tested to ensure it is working properly and accurately before cutting out the existing one from the refrigerator to install the new one? Is there a multimeter reference chart with expected values at various temperatures for the sensor?
