In any furnace, a breaker is an automatically operated switch. In case of unpredictable or extraneous currents, it prevents any damage that can happen to the furnace’s internal components. If while checking about your furnace, you find two breakers and since then you have been wondering why my furnace has two breakers, then this blog is for you. Moreover, apart from solving this question, the blog will also tell you if there is a breaker switch for the furnace or not.
Is there a Breaker Switch For the Furnace? Where is the Furnace Switch Located?
In most cases, yes, there is a breaker switch for the furnace. Depending on the type of furnace and installation, the location of the furnace switch may vary. Typically, the breaker is located near the furnace only or it is located in the main electrical panel of the house. Now that you have understood if there is a breaker switch for furnaces or not and where the furnace switch is located, let’s also answer your question- why does my furnace have two breakers?
Why Does My Furnace Have Two Breakers? What is the Purpose Of Having Two Breakers For a Furnace?
Due to power consumption and safety considerations, it’s typical for certain furnaces to include two breakers. The breakers are meant to safeguard the boiler from dangerous electrical overload, which might harm the system.
The blower motor and other low-voltage parts of the furnace are powered by one of the breakers, which is typically a typical 120-volt breaker. The furnace’s heating elements are powered by the other breaker, which is normally a 240-volt breaker.
The furnace can draw the required amount of power from two breakers without overtaxing any one circuit. This can maintain the system functioning properly and assist to avoid electrical issues. This explains what is the purpose of having two breakers.
What is the Difference Between a Single-pole and Double-pole Breaker For a Furnace?
The difference between a single-pole and double-pole breaker for a furnace are as follows-
1. Single-Pole Breakers
- The single-pole breakers are narrow switches.
- They are wired with one hot wire and one neutral wire.
- They provide 120 volts, 15-20 amps.
- If an overload in a single-pole circuit occurs, only a specific breaker will trip.
- These breakers are used in a number of appliances like TVs, radios, general lighting outlets, power tools, curling irons, vacuums, fans, clocks cellphone chargers, air compressors, and the like.
- In a furnace, this type of breaker is typically used to power only certain components like the control circuit or the blower motor.

2. Double-Pole Breakers
- These breakers have double switches.
- They are wired with two hot wires that are connected by a single neutral wire.
- They provide 240 volts, 20-60 amps.
- They are used in electric ranges, central air conditioners, electric dryers, electric baseboard heat, electric water heaters, hot tubs, etc.
- They can also be used in appliances with lower voltage circuits.
- In a furnace, this type of breaker is used to power the heating element.
What are Common Reasons for a Furnace Breaker to Trip?
The points will explain what are some common reasons for a furnace breaker to trip-
1. Dirty Air Filter: A dirty air filter can cause the furnace to work harder than it needs to, leading to increased electrical demand and potentially tripping the breaker.
2. Overheating: If the furnace overheats, the breaker may trip to prevent damage to the unit. This could be due to a malfunctioning blower motor or a clogged air duct.
3. Electrical Issues: Faulty wiring, loose connections, or a short circuit can also cause the breaker to trip. These issues should be addressed by a qualified technician.
4. Aging Equipment: As furnaces age, they may become less efficient and require more power to operate, which can increase the risk of tripping the breaker. It may be time to replace an older furnace to prevent further issues.
Regular maintenance and inspections by a licensed professional can help identify and address these issues before they lead to a tripped breaker or other problems. But why is it important to hire a professional for electrical services related to a furnace? Let’s see.
Why is it Important to Hire a Professional For Electrical Services Related to a Furnace?
It is important to hire a professional for electrical services related to a furnace for several reasons:
1. Safety: Electrical work can be dangerous and should only be performed by a trained professional to ensure that it is done safely and correctly.
2. Expertise: Professional electricians have the training and expertise to diagnose and repair electrical issues related to your furnace, ensuring that it is operating efficiently and safely.
3. Warranties: Many furnaces come with manufacturer warranties that require professional installation or repairs. Hiring a professional ensures that you will not void the warranty and that any repairs or replacements will be covered.
Overall, hiring a professional electrician to work on your furnace can provide peace of mind knowing that the job is done correctly and safely. Additionally, it can save you time and money in the long run by avoiding potential issues or costly mistakes. After this, let’s explore what are some preventative measures to avoid issues with furnace breakers.

What are Some Preventative Measures To Avoid Issues With Furnace Breakers?
Here are some preventative measures to avoid issues with furnace breakers:
1. Regular Maintenance: Schedule regular maintenance for your furnace to ensure it is running efficiently and safely. This includes checking the electrical system and connections.
2. Replace Filters: Replace the furnace filter regularly to ensure proper airflow and to prevent the furnace from working harder than it needs to.
3. Upgrade Electrical Panel: If your electrical panel is outdated or cannot handle the electrical demands of your furnace, consider upgrading to a larger panel or adding a sub-panel.
4. Unobstructed Vents: Ensure that all vents and registers are free of obstructions and that air can circulate freely.
5. Proper Thermostat Settings: Set your thermostat to a reasonable temperature and avoid setting it too high, which can cause the furnace to work harder than it needs to.
