LG Intermittent Electrical Connection in Handle or PCB

Vacuum will not start unless the handle is held or twisted in a certain position.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Cracked solder joints on handle PCB, Damaged internal wiring harness, Loose connector between handle and main body, Stress damage from drops

Safety first: Remove the battery. Do not continue flexing the handle excessively as this can worsen the damage.

1. Visual inspection: Check the handle and body for cracks or signs of impact.
2. Gentle wiggle test: With the battery installed and unit on, gently move the handle. If power cuts in and out, an internal connection is loose.
3. There is no simple user repair for internal wiring or PCB cracks. The handle or main body assembly typically must be replaced by a technician.
