What causes a furnace to stop working?

There are several reasons why your furnace might stop working, from minor issues to major breakdowns. Some of the most common causes include::
  • Lack of power: Check the circuit breaker to ensure the furnace is receiving power. Make sure the power switch near the furnace is also on.
  • Thermostat problems: Check that the thermostat is set correctly to 'heat' and at a temperature higher than the current room temperature. Replace batteries if the display is blank or not working. Try resetting the thermostat or replacing the batteries. If that doesn't solve the problem, the thermostat may need to be replaced.
  • Clogged air filter: A clogged air filter can cause many problems. Try replacing the filter.
  • Ignition problems: Issues with the igniter or pilot light can prevent the furnace from starting. A faulty igniter or pilot light may need to be cleaned or replaced..
  • Blower motor issues: The blower motor is crucial to distributing warm air throughout your home. If the blower motor is broken, the furnace may not produce enough heat.
  • Gas supply problems (for gas furnaces): Gas furnaces require both gas and electricity to function properly. Check that there are no gas leaks.
  • Other component failures: Other components, such as the heat exchanger, flame sensor, control board, or limit switch, can also cause furnace malfunctions..
It is typically best to avoid trying to fix the furnace on your own unless you're a qualified HVAC professional.
