Refrigerator inverter compressor board: what is safe to check
Inverter boards make variable-frequency 3-phase power for the compressor. Electrical checks of the board and compressor terminals are allowed; anything that opens the sealed refrigerant system is EPA 608 work and blocked. Boards fail more often than compressors.
Guide · Refrigerator
LG Craft Ice not making round ice
Craft Ice is slow by design and needs a cold freezer, water and the right mode. Rule out start-up time, mode setting and bin position before blaming the Craft Ice module.
Guide · Refrigerator
LG linear/inverter compressor fridge not cooling
Rule out demo mode, airflow, fans and defrost first, then use LG's forced-run diagnostic to see whether the compressor runs. If the compressor runs but doesn't cool, or won't start with a good board, it's a sealed-system failure: refer it to LG service or an EPA 608-certified technician and check the compressor warranty.

Component test · Washer
Washer motor control unit / inverter board
Direct-drive and inverter washers use a motor control unit (MCU) that powers a 3-phase motor and reads a hall sensor or tach. Separate MCU, motor windings, hall sensor and harness before buying a board.
Guide · Washer
LG LE code: testing the hall sensor and stator
LE means the board drove the motor but did not see rotation. Check the harness, then test the hall sensor (about 10 kΩ per channel and a pulsing signal), then the stator windings, before condemning the board.
Guide · Washer
Washer-dryer combo washes but does not dry
Combos are ventless and dry slowly. Clean the condenser/lint path, check load size and power (many need 240 V), then check heater or heat pump.
Guide · Washer
Top-load not agitating (fills and drains OK)
On older Whirlpool/Kenmore direct-drive top-loads, fill-and-drain-OK but no agitate/spin is the classic broken motor coupler. On newer models, look at the shift actuator/clutch, lid lock and motor.

Reading stored codes and service/test mode (overview)
Entry sequences differ by model and generation. Always confirm on the tech sheet inside the cabinet; the sequences below are examples reported for specific model families.
LG dryers

Guide · Dryer
Heat-pump (ventless) dryer drying poorly
Heat-pump dryers are slower than vented dryers by design. Real faults are usually clogged lint or condenser filters, a blocked drain path, or a cold room. The refrigerant circuit is sealed: diagnosis only.
Guide · Dryer
Dryer steam features not working
Steam dryers use a feeder or a hose supply. Check water, inlet filter and valve, then the steam generator thermistor.
Guide · Dryer
Lint filter not detected or lint filter codes
Several dryers sense the lint filter. Seat the filter fully, clean it, then check the sensing switch.
Guide · Dryer
Dryer will not connect to the app (Wi-Fi)
Most cases are 2.4 GHz network, registration or router issues; a few are module faults.
Guide · Dryer
Ventless dryer water tank and condensate codes
Condenser and heat-pump dryers collect water in a tank or pump it out. Empty tank, clean float, clear hose.

PTAC error codes: how to read and clear them
Most PTAC brands store fault codes that can be shown with a button combination on the control (for example GE Zoneline uses a MODE + another key sequence on some models). Read the active code, fix the cause, then clear it.
Guide · Air Conditioner
Mini-split indoor unit blinking light (reading the code)
A blinking pattern is a fault code. Count the blinks before you reset power, because a breaker reset erases the code. Then look it up for the brand and fix the cause.
Guide · Air Conditioner
Portable AC shows water-full code or keeps filling
In humid weather or dry mode, a portable can collect water faster than it evaporates it. Drain and set up a continuous drain first; a code with an empty tank points to the float switch or internal pump.
Guide · Air Conditioner
Mini-split communication error: interconnect wiring check
Most communication faults are wiring: swapped terminals, loose screws, splices or damaged cable, often after a new install or a storm. Check power, then terminations at both ends, then the data signal, before replacing a board.

Guide · TV
OLED image retention or burn-in
Short-term retention usually clears on its own once the TV's automatic compensation runs at power-off. One manual refresh is the next step; if the ghost survives, it is permanent panel wear and the fix is a panel.
Guide · TV
Firmware update or recovery from a USB drive (Samsung, LG)
Samsung and LG let you load the model's update file from a USB stick. The format and folder rules are strict; most failures are a wrong file, wrong folder or wrong format.
Guide · TV
Bluetooth / smart remote won't pair
Smart remotes use Bluetooth/RF for most keys and IR only for a few (often power). Fix batteries first, then reset and re-pair close to the TV sensor.
Guide · TV
Sound but no picture (backlight / LED strip test)
The flashlight test tells you in one minute whether the panel is producing an image with no backlight. If you can see a faint image, the LED strips or LED driver are the likely fault; if not, look at T-con or main board.

Reading the model number
LG model numbers start with a letter; serial numbers start with 3 digits.
Manufacture date from the serial number
Cross-checkedDigit 1 = last digit of the year. Digits 2-3 = month (01-12).
EXAMPLE ONLY: 503KWXY12345 -> year ending in 5 (2015 or 2025), March.
Decade is not encoded. One home-inspector reference describes digits 2-3 as the week, but LG's own help page and another guide say month.
