What causes a heater to stop working?
Often, the issue is that the heating system is simply dirty. ... The system's heat exchanger cannot work unless there's sufficient air moving across it to stop it from overheating. In short, a dirty blower can cause the heat exchanger to fail. Dirty air filters could also be the reason your heater stopped working.
Why is my heat running but not heating?

Check Your Furnace Air Filter
