Heater for home not turning on?

If your home heater isn't turning on, first check the thermostat settings to ensure it's set to "heat" and the desired temperature is above the current room temperature. Next, inspect the power supply; make sure the heater is plugged in and check for any tripped circuit breakers. If everything seems in order, it might be a problem with the pilot light (for gas heaters) or a faulty ignition system, and you may need to call a professional for further diagnosis. Regular maintenance can also help prevent such issues in the future.
