It may sound like a no-brainer, but you do need to turn your thermostat to the “heat” or “automatic” setting before your heater will click on.
Why did my heater suddenly stopped working?
Dirty filters are the most common cause of furnace problems. Dust and dirt restrict airflow—and if the filter gets too clogged, the heat exchanger will overheat and shut off too quickly, and your house won't warm up. If the blower is running but no heat is coming out, replace the filter.
What to check if heat is not working?
Raise the thermostat four or five degrees and wait an hour or so to see if the heat starts kicking on. Check all vents and heat registers to ensure they are open. Clean or replace the filter in the furnace as a dirty or clogged filter can reduce performance and efficiency.
What would cause a furnace not to kick on?
If your furnace is not turning on you should first check if the filter is clean. Dirty filters cause insufficient airflow and can prevent the furnace from starting. Other reasons it won't start can stem from improper thermostat settings, forgetting to turn on the gas line, or faulty pilot light.
Why is my heater not heating?
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.
