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 .
