How do I reset my furnace?

Before calling for repairs, consider resetting your furnace. Here's how to reset most furnaces:
  1. Turn off the furnace: Set the thermostat to the 'off' position.
  2. Turn off the power: Locate the circuit breaker for your furnace and switch it off.
  3. Wait: Wait a few minutes for the system to reset.
  4. Turn the power back on: Flip the circuit breaker back to the 'on' position.
  5. Turn on the furnace: Turn the thermostat back on and set it to your desired temperature.
If the problem persists or if you encounter error codes, don't attempt to diagnose or repair the issue yourself.

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: A faulty thermostat may not be signaling the furnace to turn on. A malfunctioning thermostat requires replacement.
  • Clogged air filter: A clogged air filter can cause many problems. Try replacing the filter.
  • Ignition problems: The igniter or pilot light (in older furnaces) is responsible for lighting the burners. A faulty igniter or pilot light may need to be cleaned or replaced..
  • Blower motor issues: The blower motor circulates air through the furnace and ductwork. A faulty motor can prevent air from circulating properly..
  • 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..
If you cannot identify or resolve the issue yourself, contact a qualified HVAC technician for diagnosis and repair .

What is a heat exchanger in a furnace?

The heat exchanger is a vital component in a furnace. It warms the air blown into your home. The heat exchanger also acts as a barrier between the combustion gases and the circulating air, preventing harmful gases, such as carbon monoxide, from leaking into your living space.. Regularly checking and cleaning your heat exchanger and scheduling professional maintenance are crucial for ensuring its proper function, preventing cracks, and maximizing its lifespan.

What are some tips for maintaining my furnace?

Regular furnace maintenance is key to preventing costly repairs and ensuring its efficient operation. Here are some tips:
  • Change the air filter regularly (every 1-3 months): A dirty filter restricts airflow, reducing efficiency and potentially damaging the system.
  • Schedule an annual furnace tune-up: A professional technician can inspect, clean, and test all components, ensuring optimal performance and safety.
  • Keep the area around the furnace clear: Remove any flammable materials or obstructions that could block airflow.
  • Check and clean the furnace vents: Make sure vents are not blocked by furniture or other items.
  • Install a programmable thermostat: This helps optimize heating schedules and save energy.
  • Seal air leaks around windows and doors: This prevents heat loss and improves efficiency.
Proactive maintenance can prevent unexpected breakdowns and reduce energy bills.

  1. Turn off the furnace: Set the thermostat to the 'off' position.
  2. Turn off the power: Locate the circuit breaker for your furnace and switch it off.
  3. Wait: Wait at least 30 seconds, though longer is sometimes recommended for the system to fully power down.
  4. Turn the power back on: Flip the circuit breaker back to the 'on' position.
  5. Turn on the furnace: Turn the thermostat back on and set it to your desired temperature.
If the problem persists after the reset, don't attempt to diagnose or repair the issue yourself.

What causes a furnace to stop working?

There are several reasons why your furnace might stop working, ranging from simple issues to more complex problems. Here are some possible culprits:
  • Lack of power: Check the circuit breaker to ensure the furnace is receiving power. A tripped breaker is a common and easily resolved problem.
  • Thermostat problems: A faulty thermostat may not be signaling the furnace to turn on. A malfunctioning thermostat requires replacement.
  • Clogged air filter: A dirty air filter can cause many problems. Try replacing the filter.
  • Ignition problems: The igniter or pilot light (in older furnaces) is responsible for lighting the burners. In newer furnaces, electronic ignition systems control this process and should be checked if there are problems.
  • Blower motor issues: The blower motor circulates air through the furnace and ductwork. A faulty motor can prevent air from circulating properly..
  • Gas supply problems (for gas furnaces): Make sure the gas supply valve to the furnace is turned on.. 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..

The heat exchanger also acts as a barrier between the combustion gases and the circulating air, preventing harmful gases, such as carbon monoxide, from leaking into your living space.. Cracks in the heat exchanger can be very dangerous, causing carbon monoxide to enter your house. Annual maintenance by a professional is highly recommended.
