Before attempting to change the bulb in your electric fireplace ensure that it has been unplugged from the wall, or that the power to it has been isolated.

To change the bulb, remove the access cover typically located at the back of the fireplace before taking out the old bulb and replacing it with the new one.

Put the access cover back onto the fireplace and restore the power. Turn on the electric fireplace to test whether the replacement bulb works.

It the change has been successful then the electric fireplace will be displaying the flame effects correctly.
