Some models of electric fireplace come with a thermostat to help keep the room at a constant temperature.
Many electric fireplaces also come with an overheat protection mode as a safety feature to prevent the fireplace from overheating.
If your electric fireplace keeps shutting or turning off, and won’t stay on:
The temperature in the room may be reaching the temperature set on the electric fireplace’s thermostat.
Ensure that the dial is set above the current room temperature or the fireplace heater will keep shutting off. The thermostat dial will make a ‘clicking’ sound when turning to let you know what the current room temperature is.
The electric fireplace may have overheated and gone into overheat protection mode.
Turn your electric fireplace off at the unit, and turn it off and unplug the power cable at the wall socket. Leave the fireplace for a period of time to cool down, and then try using it again.
Ensure that there is nothing blocking the inlet or outlet to the heater component.
Ensure that the electric fireplace heater is clean and dust free.
Ensure that the electric fireplace isn’t located in a confined space, such as in a cupboard, which can lead to the fireplace overheating.
