The LG mjh66365301 is a PCB supporter designed to secure and stabilize a printed circuit board within an LG home appliance assembly. This mounting component holds the control board in its designated position, reducing mechanical stress on the board and its solder connections during normal operation. It is a direct OEM-sourced replacement part intended for service technicians performing component-level repairs on LG appliances.
This PCB supporter is used in residential LG home appliance applications where the original mounting hardware has cracked, broken, or gone missing. It is typically installed during a control board replacement or as part of a broader repair procedure when the existing support structure no longer holds the board securely. Appliance repair technicians and authorized LG service professionals are the primary installers of this component.
Designed as an OEM-style replacement PCB supporter for LG home appliances. Refer to the LG parts lookup tool using the appliance model number to confirm fitment before ordering.
Installation should be performed by a qualified appliance repair technician. Disconnect power to the appliance at the outlet or circuit breaker before accessing any internal components. Handle the circuit board carefully to avoid static discharge damage — use an anti-static wrist strap when practical. Reinstall all fasteners and verify the board is seated and supported correctly before restoring power.
