Why Do My Lights Flicker When the Furnace Turns On?

If you’ve noticed that your power flickers when the heat comes on, you may have a severe issue. It’s a good idea to contact an HVAC professional right away to inspect and repair your furnace. If you frequently have flickering lights when you turn the furnace on, it could indicate an electrical problem or other concern.

The circuit is overloaded.

Your electrical panel, also called a fuse box or breaker box, is part of your home’s electrical system. It’s full of circuits and breakers that supply power to your fixtures and appliances. If your furnace shares a circuit or breaker with a light, it may dim or flicker when the heater comes on. In this case, you just need to make sure your heater has its own circuit and breaker.

The wires are exposed.

All wires should be fully encapsulated with sheathing. If the wires on the furnace’s power cord are exposed, this can cause electricity to skip from one wire to another and can start a fire. If you notice any exposed wires, be sure to have a licensed electrician address them right away to prevent any serious damage.

The distribution panel is overloaded.

Every home has a maximum amount of voltage that can be safely supplied to the structure through the distribution panel. When you add too many appliances to a single power source in your home, you can cause the circuit breaker to trip.

To ensure your safety and comfort, you should always contact an HVAC expert if you have concerns about the condition of your furnace. In the long run, it’s extremely beneficial to have your furnace properly inspected, maintained, and repaired throughout the year.
