If your Insignia Heater shuts off unexpectedly, it could be due to several reasons. First, ensure the heater is properly plugged into a working electrical outlet. If the set temperature is lower than the room temperature, increase the set temperature. If a safety device was activated, place the heater upright, check for obstructions, unplug it, wait 10 minutes, remove any obstructions, and restart it. If the problem persists, have it checked by an authorized service person.
