blower runs constantly

I have an elect aire furnace. The blower runs constantly but there is no heat. The code flashing says limit circuit open. Any suggestions to the problem?

Pull out the wiring schematic. There should be a bonnet thermostat that is probably stuck on hi temp ('stat contacts open) or an open in the circuit. That would shut off the heat circuit and keep the blower running. Troubleshoot with a multimeter.

If it is an ELECTRIC furnace then BEWARE!!!!!! HIGH VOLTAGE EXISTS in the cabinet.
