Ruud furnace blower and burners run continuously

My Ruud furnace just started running non-stop. Both the burner and blower stay on constantly and the only way to stop is to unplug the unit. Continues even if thermostat is disconnected.

Ruud furnace blower and burners run continuously

Does it continue if you disconnect the thermostat wires at the furnace? Note where the wires are connected before removing them. If that stops it, your thermostat wires are shorted out somewhere.
