Parts for Lg LSC21943ST / ASTCLGA: Section 3 Parts

The LG Refrigerator Water Filter is an OEM Replacement Part. It is designed to improve the quality of water and protect refrigerators and ice machines from sediment deposits. This NSF-Certified filter effectively reduces iron and particulates. It also preserves beneficial minerals like fluoride. The filter measures 5.6 inches high and 3.3 inches in diameter.

It is installed by removing the top shelf and pulling the old filter downward. Then turn it counter-clockwise, and replace it with the new filter aligned in a horizontal position. To ensure the best performance and the removal of trapped air and contaminants, it's recommended to flush the dispenser with 2.5 gallons of water in alternating cycles. If your model includes a water filter indicator, press and hold the Filter or Reset button for 5 seconds after installation. With a lifespan of 6 months and a 500-gallon capacity, this filter provides both quality and longevity.

This controller assembly is the appliance's main electronic control that manages cycles and user inputs to restore proper control operation. Replace a failing controller assembly to address unresponsive controls, incorrect cycle behavior, or intermittent errors. What it does:

• Manages cycle selection, timing, and communication between sensors and motors to coordinate appliance operation.
• Interprets user inputs from the front panel and sends commands to other components.
• Failure may cause unresponsive buttons, unexpected error codes, stalled or incorrect cycles, or an appliance that won't start.
• Replacing the assembly often resolves control-board–related faults when diagnostics point to the main controller.

• Disconnect power (unplug or switch off breaker) before removing the old assembly to avoid shock or damage.
• Handle the board and connectors carefully; avoid static discharge and cradle the assembly by its edges.
• Match the replacement to the exact part number and transfer any brackets, grounding straps, or button housings as needed.

This LG OEM bulb is also compatible with Sears/Kenmore models.
