Customer Questions and Answers for Refrigerator Temperature Sensor by Lg

Hello Freddy, This sounds like it could be a possible sealed system restriction or possibly a Freon loss. You will need to remove the evaporator cover and inspect the frost pattern to determine the issue. If there is an ice ball where the Freon lines enter the freezer compartment, it is a Freon loss causing the issue and the leak will have to be located and sealed before Freon is re-introduced into the unit. If there is just frost in the center or other area of the evaporator coils or even frost building up on a Freon line behind the unit, the issue will be a sealed system restriction. Either case requires a Freon certified technician to complete the repair since Federal law requires it.
