Field pattern: LG ice maker code (1F / IF) or ice maker stopped (frost on the ice maker fan; find the air leak)

Moist air reaching the ice maker area freezes around the fan until the blade cannot turn, and the control flags the fan. Thawing clears it for a while, but the fix is to find the moisture source (door gasket, door opening habits, blocked vents) and check the fan. The wrong turn is replacing the fan or board without defrosting and without fixing the air leak.

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.
