Experiencing unexpected shutdowns with your Lasko 5409 oscillating ceramic tabletop space heater? This issue often stems from the heater's built-in safety mechanism, designed to prevent overheating. To reset your Lasko 5409 and potentially resolve this, follow these steps: First, unplug the heater from the electrical outlet. Allow the unit to cool down completely; a waiting period of at least ten minutes is recommended. Once cooled, plug the Lasko 5409 back into the outlet. Finally, refer to your user manual for the correct operational procedures to turn the heater on and adjust your desired settings. Following these steps should allow your heater to resume normal operation.
