What does it mean when electric heater blows cold air? When a furnace only blows cold air, there’s a chance the heater could have overheated. But don’t worry, this usually doesn’t mean the unit is broken. When the system overheats, there’s a safety feature that shuts the system off. This is a good thing—it could prevent a fire, carbon monoxide leak, or even an explosion.
Why is my electric heater not getting hot? CAUSE: The most common cause for electric heater not working is blown fuses. SOLUTION: To check this, first unplug the device and check the fuse box of the house for blown fuses as well as tripped circuit breakers.

It may also be hidden behind a removable metal panel on the unit—and then behind some insulation. Once you find the button, push and release it.
