  • Help with Luxaire furnace (blower won't stop)

    Hello everyone...I am new here and I am hoping that someone can help me out. I have a Luxaire model #PCUHALD12N080. My problem is that the burners come on until overheated and once they shut off, the blower will continue to blow cold air until the system cools and then the blowers reignite. This happens continuously on a 45 minute to hour basis. Any suggestions on what I can do would be greatly appreciated .

    Your furnace is reaching its high temperature limit. You have a restricted duct system, dirty filter, weak blower motor, dirty evaporator coil, etc... Or it could be a faulty high limit switch or the gas valve could be adjusted wrong and the furnace could be over-firing. Get a qualified tech out to inspect it before it burns your house down.

      Excellent advise .... No way can anyone know what's really wrong without a good checking things out and that needs to be done by a good HVAC tech. If he leaves it run as is, I would hate to think what could happen.
