While flickering lights can stem from a major electrical problem, it is more likely that the issue is related to the bulb or switch. However, it is essential to identify the cause of the flickering lights so you can rule out any serious electrical issues. Learn the most common causes of flickering lights and how to fix them, as well as when it’s advisable to call an electrician. 6 Potential Causes of Flickering Lights Before calling an electrician, try troubleshooting these potential causes of flickering lights. 1. Bulb Issues One of the most common causes of flickering lights is an issue with the bulb. Fortunately, bulb issues are also the easiest fix. Solution: If you suspect the light bulb is burning out, you can easily test your theory by replacing the light bulb. If the new one doesn’t flicker, you’ve likely solved the problem. 2. Switch Issues Light switches see a lot of use. While premium switches may last a lifetime, budget light switches are likely to fail over time. In this case, you might notice the lights flicker when you touch the switch. Solution: If you suspect the light switch is causing the flickering lights, replacing the switch should solve the problem. To do so, turn off the electricity and the circuit breaker box, remove the switch plate, and uninstall the light switch. Wire and install the new light switch exactly like the old one, reinstall the switch plate, and restore the power. 3. Fixture Issues Less commonly, the light fixture itself may be to blame. If there are loose connections or corrosion in the fixture, the lights may flicker. Solution: You can attempt to repair the fixture by fixing the connections or removing corrosion, especially if it’s a premium fixture. However, it may be more beneficial to replace cheaper light fixtures. 4. Incompatible Bulb or Dimmer Switch If you’ve ever shopped for light bulbs, you may have noticed language on the box referring to dimmer compatibility. This is because some types of bulbs and dimmer switches don’t play well together. If you install a light bulb that’s incompatible with the light switch, it will likely flicker as a result. Solution: To ensure your light bulb is compatible with your switch, check the bulb’s specifications before purchasing a replacement. If you’re having trouble finding a light bulb that won’t flicker due to dimmer incompatibility, your best bet is to try a traditional incandescent light bulb. However, they may be difficult to find in some areas due to government restrictions on energy usage. Even LED light bulbs that specify dimmer compatibility can sometimes flicker when tied to a dimmer switch. 5. Wiring Issues Sometimes, the fixture, the bulb, and the switch may all be in good, working condition, but the wiring is to blame for the flickering lights. The wires could be worn or damaged, but it’s more likely that they are loose, causing an intermittent connection, which results in a flicker. Solution: With the power turned off, inspect the wiring and all relevant connections, including those at the switch, circuit breaker, and light fixture. 6. Electrical Load Issues If you notice the lights flickering whenever other appliances turn on, such as a vacuum, dishwasher, blow dryer, or other power-hungry products, it’s likely because you’re running them on the same circuit as the lights, causing an excessive electrical load on the circuit. Whenever these devices turn on, they draw a large amount of power, which causes the current running to the lights to fade, resulting in flickering. Solution: If the circuit is overloaded, move the high-power appliance to a different circuit. For something like a blow dryer or vacuum, unplug it and plug it into a different outlet. Install a dedicated circuit for large, permanently installed appliances, such as dishwashers. When It’s Time to Call a Professional Electrician If none of these solutions resolve your flickering lights or if the lights are accompanied by buzzing sounds, burning smells, heat around the fixture or outlets, or frequently tripping breakers, contact a professional electrician immediately. You should also consider professional help if multiple lights in your house are flickering and the issue isn’t isolated to a single fixture or circuit. If you haven’t already, a professional will likely instruct you to cut the power at the breaker until the problem can be remedied.

What Is That Burning Smell from the Furnace? How to Prevent Unpleasant Odors

ByTimothy Dale

As temperatures start to drop, homeowners make the switch to heating to ensure the home remains comfortable. However, the warm air can often be accompanied by a burning smell that quickly permeates your space. However, there are ways to prevent this odor in the first place and other methods for handling unfamiliar odors, like a musty or electrical burning smell. Use this guide to discover how to prevent the furnace smell when you turn it on for the season, other mysterious furnace smells you might encounter, and when to call a professional. Why Does the Furnace Smell When You First Turn it On? In most cases, when a furnace smells after being turned on for the first time in the season, there’s no need to worry. The smell of burning dust should fade quickly. But, if the smell persists or you notice a different smell from the furnace, it could be due to a serious issue with the HVAC system. Consider these common reasons why the furnace may smell when you first turn it on. Burning dust smells are relatively common when first turning on the furnace for the season. This is typically due to a buildup of dust on the burners, heat exchanger, air ducts, and other heating unit components. Generally, this odor will fade quickly as the thin layer of dust is burned away. Musty odors coming from the furnace usually indicate that there is mold or mildew trapped inside the HVAC system. It may be in the heating unit, the ductwork, the furnace filter, or even the humidifier pad. Electrical burning smells are not normal and should be addressed as soon as possible. Sometimes the smell is due to a foreign object stuck in the ductwork or vents of the HVAC system, but on other occasions, this smell may be due to burned or frayed wiring, or can also be a result of the furnace overheating. Rotten egg scents produced by the furnace are a sign of a gas leak. Since natural gas is odorless, the gas companies add a sulfur-based chemical to give off the distinct odor of rotten eggs as a way of warning homeowners that there is gas in the vicinity. Gas is flammable, putting the home at risk of a fire or an explosion, and it’s also harmful if inhaled, so you should vacate the home immediately. Smoke smells can occur if the exhaust vent is blocked, forcing the combustion exhaust from the furnace to escape into the home. This smell may also be a result of flammable material inside the ductwork, near heating vents, or too close to the furnace. Animal odors are often due to pets. Pet hair and dander are taken into the ducts through the cold air return, where they will remain in the ducts. Every time the furnace turns on, it recirculates pet hair and smells, until you have your ducts professionally cleaned. It’s also not unheard of for a pest to enter the ductwork of the home, where droppings and hair will produce a foul odor when the furnace is turned on. Oil smells can indicate that the filter on the furnace is clogged. This is typically due to a problem with the filter, which can be easily resolved by an experienced DIYer or a professional HVAC tech. Sewage stenches are powerful and off-putting, but can also help identify when there is a problem with the home sewage system. If the furnace starts to smell like sewage when it is first turned on then there may be a broken wastewater line or an open sewer line nearby that will need to be located and repaired. Chemical smells from the furnace should not be ignored. This could indicate that the heat exchanger is broken or not operating properly, which may lead to the release of odorless, invisible carbon monoxide gas; a known risk of gas-based heating systems. How to Prevent the Furnace Smell When You Turn It On Burning Dust Smell While the burning dust smell that comes from the furnace when it is first turned on is relatively harmless, that doesn’t mean you need to just deal with it each year. Instead, you can have the furnace and evaporator coil cleaned by a professional before the cold season begins. DIYers with enough experience and confidence can clean the evaporator coil in a furnace on their own by turning off the furnace, removing the access panel, then gently cleaning the coil with a soft cloth or brush, while being careful to avoid damaging the fins. Wipe down the condensate pan and the surrounding areas, then replace the panel and turn the furnace back on. You should also take this opportunity to replace the air filter, where dust might be trapped from the previous season. If the burning dust smell persists, then it’s recommended to turn off the furnace and contact an HVAC professional to inspect and repair the HVAC system. Musty Odors Musty odors are typically produced by mold and mildew. In some cases, the mold or mildew is attached to dust or other debris, so it burns off relatively quickly, but if the musty odor doesn’t go away, then you should start by replacing or cleaning the air filters. Similarly, you can replace or wash the humidifier pad using a solution of water and vinegar to kill any mold or mildew. However, if the musty odor still
