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
