LG VC3716S - Manual (Page 9)

Thermal protector :
This vacuum cleaner has a special thermostat that protects the vacuum cleaner in case of
motor overheating. If the vacuum cleaner suddenly shuts off, turn off the switch and unplug
the vacuum cleaner. Check the vacuum cleaner for possible source of overheating such as
a full dust tank, a blocked hose or clogged filter. If these conditions are found, fix them and
wait at least 30 minutes before attempting to use the vacuum cleaner. After the 30 minute
period, plug the vacuum cleaner back in and turn on the switch.
