We all know how much we rely on our furnaces to keep our homes cozy and warm, especially during those chilly Washington winters.
But what happens when there’s a power outage, and your furnace suddenly stops working?
Don’t worry, BelRed is here to help you out.
In this article, we’ll discuss the possible reasons behind a furnace not working after a power outage and the steps you can take to get it up and running again.
Let’s dive in!
What is a Power Outage?
A power outage occurs when there’s no electricity coming into your home due to issues with the electrical grid, power stations, or electric lines leading to your house. Outages can affect a few streets, an entire town, or even a larger area, causing disruptions to your daily life.
Power Outage vs Power Surge: What’s the Difference?
While power outages are the absence of electricity, power surges are the opposite. Power surges occur when there’s too much power coming into your home, surpassing the usual 120 volts. These surges can be caused by lightning strikes or problems with the electrical lines and can damage your electronics and appliances.
Why is My Furnace Not Working After Power Outage?
There are several reasons why a furnace may stop working after a power outage. The most common of these include:
- Tripped Circuit Breaker
- Blown Fuse
- Damaged Control Board
- Furnace Lockout Mode
- Safety Switches in Improper Positions
- Thermostat Power Issues
- A System Reset Is Necessary
Keep reading to learn more about each cause.
Tripped Circuit Breaker
A power outage can sometimes cause a circuit breaker to trip, cutting off power to your furnace. Locate your electrical panel, find the breaker connected to your furnace, and check if it has tripped. If so, flip it back to the “on” position and see if your furnace starts working again.
Blown Fuse
Power surges during a power outage can cause your furnace’s fuse to blow. Examine the fuse box for any blown fuses and replace them if necessary.
If you’re unsure about doing this safely, contact a professional HVAC technician for assistance. Call us at (855) 345-6161 to schedule an appointment, ASAP!
Damaged Control Board
Power surges can also damage the furnace’s control board, hindering its proper functioning. If you suspect that your furnace’s control board is damaged, you’ll need to call an experienced technician to assess the situation and replace the control board if required.
Furnace Lockout Mode
Many modern furnaces have a safety feature called “lockout mode,” which activates when the furnace encounters difficulties starting. A power outage could trigger this mode, causing the furnace to shut down to prevent further damage.
To reset the lockout mode, turn off the furnace’s power for about 30 seconds and then turn it back on. If the issue persists, consult a professional.
Safety Switches in Improper Positions
After a power outage, verify that all safety switches, such as gas valve switches, limit switches, and blower door switches, are in their correct positions before restarting your furnace.
Thermostat Power Issues
If your thermostat has no power or has weak batteries, it may not communicate with your furnace correctly. Address potential thermostat issues by checking its power, replacing low batteries, and resetting functions as needed.
A System Reset Is Necessary
Your furnace may need a system reset after a power outage. Perform a reset by following the appropriate steps outlined in your owner’s manual, which may involve locating and pressing the reset button on your furnace.
By addressing these potential issues, you can improve the chances that your furnace will work correctly after a power outage. If you continue to experience problems, don’t hesitate to contact a professional for assistance.

Signs a Blown Fuse is Causing Malfunctions in Your Furnace
There are three common signs that indicate a blown fuse is causing your furnace to malfunction. These signs include:
- Electrical issues in other areas of your home: If you’re experiencing electrical issues in other parts of your home after the power outage, such as flickering lights or non-functioning outlets, this could indicate a blown fuse in your furnace as well.
- Visible damage to the fuse: If you’re comfortable checking the fuse box yourself, look for any fuses that appear damaged, burnt, or discolored. A blown fuse will often have a broken or melted metal strip inside the fuse’s glass window.
- Failed multimeter test: If you have a multimeter and know how to use it safely, you can test the fuse for continuity. A blown fuse will not have continuity, indicating that it needs replacement.
Remember that working with electricity can be dangerous. If you’re unsure about how to handle any of these steps or if you suspect a blown fuse is causing your furnace not to work, it’s best to contact a professional HVAC technician for assistance.
Signs a Damaged Control Board Is Causing Malfunctions in Your Furnace
If a damaged control board is causing your furnace to malfunction, it could develop the following signs:
- Blower fan issues: The control board regulates the blower fan, which is responsible for circulating air throughout your home. If the fan runs continuously, doesn’t run at all, or operates at inconsistent speeds, a damaged control board could be the culprit.
- Ignition problems: A damaged control board can cause issues with the furnace’s ignition system, such as the igniter not glowing or the gas valve not opening. This can result in the furnace not producing heat.
- Error codes or flashing lights: Many modern furnaces have diagnostic systems that display error codes or flashing lights to indicate a problem. If your furnace displays an error code or flashing lights related to the control board, it’s likely that the control board is damaged or malfunctioning.
- Unresponsive to thermostat adjustments: If your furnace doesn’t respond to changes in thermostat settings, the control board may not be communicating correctly with the thermostat, indicating damage or malfunction.
If you suspect that a damaged control board is causing your furnace not to work after a power outage, it’s crucial to contact a professional HVAC technician. They can accurately diagnose the issue and replace the control board if necessary to restore your furnace’s proper operation.
Benefits of Getting Professional Furnace Repair Services
Dealing with a furnace that’s not working after a power outage can be frustrating and overwhelming. While some minor issues can be resolved with simple troubleshooting, many problems require the expertise of a professional HVAC technician.
Here are some benefits of getting professional furnace repair services:
Expertise and Experience
Professional HVAC technicians have extensive training and experience in diagnosing and fixing a wide range of furnace issues. They are familiar with different furnace models and their unique features, which allows them to quickly identify the root cause of the problem and provide an effective solution. By hiring a professional, you can be confident that your furnace will be repaired correctly and efficiently.
Safety
Furnaces involve complex electrical and gas systems, which can be dangerous if not handled properly. Attempting to repair a furnace on your own without the necessary knowledge and skills can put you and your family at risk. Professional technicians are trained to follow safety protocols and use specialized tools and equipment to minimize risks and ensure a safe repair process.
Time and Cost Savings
Troubleshooting and fixing furnace issues on your own can be time-consuming and is often a trial and error proces. Hiring a professional can save you valuable time and prevent costly mistakes. Professional technicians can quickly diagnose and resolve the problem, getting your furnace back up and running in no time. In addition, they can provide valuable advice on proper furnace maintenance to prevent future issues and prolong the life of your heating system.
Warranty Protection
Most furnaces come with a manufacturer’s warranty that covers specific parts and labor. Attempting to repair the furnace on your own can void this warranty, leaving you responsible for any future repair costs. Professional HVAC technicians are familiar with warranty requirements and can ensure that your furnace repairs are done in accordance with the manufacturer’s guidelines, protecting your warranty and investment.
Preventative Maintenance
When you hire a professional for furnace repair, they can also perform a thorough inspection of your heating system to identify any potential issues before they become significant problems. This proactive approach can help you avoid costly repairs and extend the lifespan of your furnace.
24/7 Emergency Services
Many professional HVAC companies offer 24/7 emergency services, ensuring that you have access to expert assistance whenever your furnace breaks down. This can provide peace of mind knowing that help is just a phone call away, even during weekends, holidays, or after-hours.
