LG French Door Refrigerator Model LFC25776 - the freezer light will not stay on. Bulb has been tested and is working. Is there a freezer light sensor somewhere?

Try lubricating switch

There is no light sensor that I know of in any refrigerator. The light comes on when the door is opened. This breaks a contact in the light switch. The switch for the refrigerator is part 406B on this diagram: https://www.appliancepartspros.com/case-parts-parts-for-lg-lfc25776sb.html . The switch is on the left side below the rail holder in the freezer. If the switch is good, then the freezer wiring harness may have damaged insulation or a break that intermittently comes back into contact. The wiring harness is shown as part 250F; other vendors may have this in stock.


I hope this helps. Depending on your skill and comfort level, you may want a professional repair tech to handle the repair. If the refrigerator is out of warranty (or out of warranty for labor), you need to decide if the total cost is worthwhile.
