Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

You can plug the unit back in to try again. Cycling the power like this will reset the unit but if you have an open limit error, which will make the blower run and blow cold air, a reset won't usually work. If you still need help I need the brand and model number of your unit.
