Came home 2 nights a go from work and I had my heat on high setting. Everything was blowing fine. The next day around noon when I left I tried cutting the heat back on nothing happened. I even tried to cut the cool air on and nothing happened. Not even a noise or humming or anything. I just replaced the blower motor 2 months ago. I havent checked anything yet. Just curious of what it may be. Any suggestion would be greatly appreciated
