Thermal Cut-Off And Problem Solving - Eureka 4230 Series Owner's Manual

Thermal Cut-Off
This vacuum cleaner has a special thermostat that protects the vacuum in case of motor overheating. If the vacuum
suddenly shuts off, push the power switch to off and unplug the vacuum. Check the vacuum for a possible source of
overheating such as a full dust cup, blocked hose or clogged filter. If these conditions are found, fix them and wait at least
30 minutes before attempting to use the vacuum. After the 30 minute period, plug the vacuum back in and turn on the
switch. If the vacuum still does not work, take it to a Eureka authorized service center for repair or call 1-800-282-2886.
