Why Your Furnace is Overheating and What You Can Do About It

Furnace overheating is a problem that no homeowner wants to deal with, as it can cause a variety of issues including property damage, serious financial losses, and safety risks. But with the right solutions, you can protect your home and avoid potential danger. In this article, we’ll discuss the common reasons why furnaces overheat, the potential risks of furnace overheating, and the solutions to prevent the problem from occurring.

What Causes Furnace Overheating?

Furnaces have several components that are responsible for regulating heat. If one of these components malfunctions, it can create overload and cause the furnace to overheat. Common causes of furnace overheating include:

  • An obstructed air filter – The air filter should be changed regularly to keep your heating system running efficiently. If it’s not changed on a regular basis, the filter can become clogged with dirt and dust, which can impede the airflow and cause the furnace to overheat.

  • A malfunctioning thermostat – If your thermostat isn’t working properly, it may be sending incorrect signals to the furnace, causing it to work harder than necessary and leading to overheating.

  • Excessive heating demand – If you have an older furnace, it may not have the capacity to meet the demand of your home’s heating needs, resulting in overheating.

  • A malfunctioning fan – If the fan isn’t running properly, it can overwork the furnace and cause it to overheat.

  • A faulty high limit switch – The high limit switch is designed to cut off power to the furnace when it senses that the temperature is too high. If it’s not functioning properly, it can cause the furnace to overheat.

Potential Risks of Furnace Overheating

Furnace overheating can cause a variety of safety risks, including fire and carbon monoxide poisoning. It can also cause potential property damage, as the system may not be able to shut off and could continue to run until it’s manually shut off.

Additionally, if the overheating problem is not fixed, it could lead to expensive repairs and replacement costs as the system will continue to be overworked in order to meet the demands of your home’s heating needs.

Solutions to Prevent Furnace Overheating

There are several steps you can take to prevent your furnace from overheating. Here are some solutions that can help:

  • Check your air filter – Make sure to change your air filter on a regular basis to ensure optimal airflow.

  • Verify your thermostat – Check your thermostat to make sure it’s functioning correctly.

  • Inspect and clean your fan – If your fan is dirty or worn, it will need to be cleaned or replaced.

  • Replace your high limit switch – If your high limit switch is faulty, you may need to replace it.

  • Upgrade or repair your furnace – If your furnace is old or underperforming, it may need to be replaced or repaired in order to meet the demands of your home.

  • Call a professional HVAC technician – If you’re unsure of the cause of your furnace’s overheating, call a professional HVAC technician to inspect your system and determine the issue.

The Bottom Line

Furnace overheating is a problem that needs to be addressed right away, as it can lead to potential safety risks and expensive repairs. By following the solutions above, you can protect your home and avoid potential dangers associated with furnace overheating.

Furnace Overheating Prevention

When it comes to maintaining a furnace, preventive action is an important part of keeping it running efficiently and effectively, and to avoid furnace overheating issues. Below is a list of manufacturer and Local Appliance & HVAC Technician recommended preventive action steps that residents of San Diego can take to minimize the risk of their furnace overheating:

Manufacturer Recommended Prevention Action

  1. Scheduling Regular Maintenance: Hiring a qualified technician who specializes in furnace maintenance to inspect the furnace at least twice a year, and change the filters every 1-3 months. These periodic inspections help identify potential issues before they become big problems, and saves a lot of money and trouble in the long run.

  2. Cleaning the Blower Motor and Fan: The furnace blower motor and fan should be thoroughly cleaned at least once a year. This helps keep dirt, dust, and other debris from accumulating in the system, which can reduce air flow and contribute to overheating.

  3. Check for and Clean Vents: Regularly check for and clean any clogged or blocked return or supply vents throughout the home, as blocked vents can lead to overheating due to restricted air flow.

  4. Heat Exchanger Inspection: The heat exchanger should be checked at least twice a year for signs of corrosion, cracking, or warping. If any of these issues are present, the furnace should be inspected and serviced by a qualified technician immediately to prevent further damage and possible safety concerns.

  3. Monitor the Air Flow: Signs of restricted air flow, such as a furnace that runs constantly or produces weak air flow, should be addressed immediately. This could indicate a blocked vent or a dirty filter, both of which can lead to overheating of the furnace.

  4. Take Advantage Of Regular Service: Have a qualified technician provide regular maintenance and service to check for any potential issues that could contribute to furnace overheating. This service should include inspecting the air filters, cleaning and tightening connections, oiling the motor, and inspecting any belts and pulleys.
