An electric heater that blows cold air could be caused by one or more of the following reasons:
- The manual reset has tripped.
- The fan switch is “on” and the thermostat setting is below the actual temperature
- The fan is dispersing this air after shutdown
- There may be a loose wire coming from the elements
- The heater element may be defective
