Known issue: LG bottom-freezer ice sheet on the freezer floor (frozen defrost drain)

LG's own help library describes this pattern on its refrigerators: meltwater from the defrost cycle cannot reach the drain pan because the freezer drain is blocked by ice or debris, so it runs back and freezes on the bottom of the freezer. LG's first step is a full manual defrost; if the ice returns, LG says a technician should clear the drain, which requires disassembly. Repair sites and forums report it repeatedly on LG bottom-freezer and French-door models.

Before you start

  • Unplug the refrigerator before removing the freezer rear panel.
  • Do not use sharp tools or an ice pick near the evaporator; a punctured coil is a sealed-system repair for an EPA 608-certified technician.
  • Use warm, not boiling, water near plastic liners.

Adaptive defrost control (ADC) board: how to diagnose it

An adaptive defrost board replaces the old cam timer. It counts compressor run time (and on some boards door-open time) and adjusts the next defrost interval based on how long the last one took. Test the heater and the cold bimetal first, then force a defrost: if the heater warms on a forced defrost but the coil still ices, the board isn't starting defrost on its own.

Ice dispenser not dispensing ice (ice maker is making ice)

Most cases are mechanical: cubes fused into a block, a bin not fully seated on the auger drive, or ice behind the auger motor. After that, check the electrical path: door switch, dispenser switch, auger motor voltage and, on crushed/cubed models, the cube solenoid. Water dispensing working is a useful clue that the dispenser control has power.

Refrigerator runs all the time

First decide if it's really a problem. Whirlpool says 40-80% run time is normal at average room temperature, and newer variable-speed compressors are designed to run long at low speed. If it's truly excessive, the usual causes are heat-rejection problems (dirty condenser, dead condenser fan), air leaks (gaskets, doors) and a frosted evaporator. A compressor or refrigerant fault is a referral.
