After not getting any heat and having no control over where the air was coming out of I got control of the air flaps by taking the controller out and wiggling the connections. (Probably not a good sign but at least they are still working), but STILL NO HEAT. What and how do I check next. If this still points to the controller is there a way I can manually open the heat valve till spring. A used controller from Shokan is $325.00. Any other sources you can think of?. Thanks
