Gas burners often seem slower to light during cold winter mornings. That pause between turning the knob and getting a steady flame feels longer, especially in Edmonton’s freezing kitchens. We know this can be frustrating when you’re just trying to make breakfast. This delay isn’t just your imagination—it has several real causes. Temperature, fuel behavior, and component response all change in the cold. Let’s explore the reasons behind this issue and how to handle it effectively.
Cold Air Affects Fuel-to-Air Mix
When temperatures drop, the air inside the kitchen gets colder and denser. Cold air has more oxygen, but it takes longer to mix well with natural gas during ignition. As a result, burners need a few extra seconds to balance the mixture before the flame appears. We notice that gas may hiss slightly longer before ignition during freezing days.
The gas supply itself isn’t usually the issue—it’s how it interacts with the cold air that slows things down. Most importantly, colder air also changes how long it takes for the igniter to spark the flame. This delay can be frustrating, but it doesn’t always mean your appliance is broken.
If you notice the issue only when your kitchen is cold, you’re likely dealing with this type of air-fuel imbalance. In this case, waiting a second longer might be all that’s needed before the burner lights up. However, consistent delays deserve a closer inspection.
Metal Components Contract in Low Temperatures
All gas burners rely on metal parts—jets, valves, igniters, and lines. In cold weather, metal shrinks slightly, which changes how these components operate. Our team often sees valves or regulators stiffen in freezing rooms, which delays gas flow or slows spark production. That small contraction adds to ignition time.
The colder it gets, the more pronounced this contraction becomes. For instance, igniters might not create a strong enough spark on the first try. Consequently, the gas sits unburned for a second or two before finally lighting. In rare cases, the metal parts inside the burner assembly may misalign slightly due to contraction, affecting the flame’s shape.
Addressing this requires routine checks. If the ignition problem worsens over time, it may point to worn metal parts that no longer adjust well to temperature swings. Booking reliable appliance repair services in Edmonton helps us confirm whether this is the case without replacing parts unnecessarily.
Moisture and Condensation on Igniters
Low kitchen temperatures also increase moisture buildup. When humidity inside the home rises and the temperature drops, condensation can form on cold surfaces—especially metal ones. We’ve seen this happen on igniters and gas jets, which are often cold before the appliance warms up.
If there’s even a thin layer of moisture on the ignition tip, it can interfere with the spark. In other words, the system may try to ignite, but the spark fails to jump through the damp air. This causes a delay or multiple clicks before the burner lights up. Over time, repeated exposure to moisture can also weaken the igniter itself.
To minimize this, it helps to wipe down the stovetop with a dry cloth in the morning. Even better, installing a small dehumidifier or increasing airflow helps prevent condensation on your appliance. That way, ignition happens on the first try.
Battery-Powered Ignition Can Lag in the Cold
Many gas stoves today use battery-powered ignition systems. These systems rely on a spark module that uses electricity from a standard AA or AAA battery. We’ve found that batteries lose voltage faster in colder environments, and that drop affects ignition reliability.
You might hear several clicking sounds before the flame appears—or no clicks at all. If your gas burner is battery-operated, replacing the battery regularly can prevent cold-weather lag. In extremely cold kitchens, we also suggest using lithium batteries instead of alkaline ones. Lithium performs better in low temperatures and maintains consistent voltage.
It’s a good idea to test your burner both before and after battery replacement. That way, if delays continue, you can rule out the battery as the issue and move on to the burner assembly itself. When cold weather keeps affecting ignition, we often recommend scheduling a full oven repair in Edmonton to check the entire ignition circuit.
Gas Pressure Drops During Cold Spells
Sometimes the cause isn’t inside your kitchen at all. In severe cold snaps, natural gas utilities may reduce supply pressure to protect the grid. Lower pressure affects how quickly gas flows from the line to your appliance. That means the fuel takes longer to reach the burner, causing a noticeable ignition delay.
Although this doesn’t happen often, it’s something to keep in mind if all gas appliances in the home seem slower to start during a deep freeze. We’ve also seen this when multiple appliances run at once—like a furnace, water heater, and stove—all drawing from the same line.
If you notice weak or flickering flames across all burners, it’s best to call a technician. This could signal low pressure or a problem with the regulator. For safety and performance, we always recommend a full inspection when gas pressure issues arise.
Burner Jets Can Get Blocked with Cold Residue
Burners exposed to splatter or moisture over time may accumulate debris in the jets. In cold weather, grease or food residue becomes harder and stickier, forming partial blockages. Even small build-up slows down gas flow at the outlet, delaying ignition.
Cleaning burner caps and jet holes regularly helps prevent this. We typically use a soft brush and a toothpick to remove buildup. Avoid harsh cleaners or sharp tools—they can damage the jets. For deeper cleanings, a professional service is safer and more thorough.
If your burner lights unevenly or flares up after finally igniting, this may be your issue. Regular cleaning not only improves ignition but also prevents uneven cooking and gas waste.
Indoor Temperature Drops Below Ignition Threshold
Some electronic ignition systems have built-in safety controls. If the internal sensor detects extremely low temperatures, it may delay operation or prevent ignition. These systems are designed to avoid gas buildup if they can’t generate a strong enough spark.
In very cold homes, especially overnight, the temperature near the stove can dip below the safe threshold. We recommend keeping the kitchen above 10°C (50°F) whenever possible. Adding extra insulation near exterior walls or sealing drafts also helps maintain ignition reliability.
In a few rare cases, systems misread the temperature and block ignition even in moderate cold. If your stove has trouble lighting even when the room feels warm, faulty temperature detection could be the issue. Our team handles this with a full check during scheduled service.

FAQ
Why does my gas burner only take longer to light in winter?
Cold temperatures affect air density, metal parts, and even battery voltage. All these slow down the ignition process during winter months.
Can I still use my gas stove if ignition takes longer?
Yes, but always stay nearby during ignition. If the flame doesn’t appear within a few seconds, turn off the burner and wait before trying again.
Is moisture buildup really that common in kitchens?
Yes, especially in colder homes with limited ventilation. It often collects on metal parts and causes brief ignition issues.
How often should I clean the burner jets in winter?
We suggest checking them monthly if you cook often. In colder months, grease hardens faster, leading to more blockages.
Should I replace the igniter if delays continue in spring?
If delays happen even when temperatures rise, the igniter may be worn. A technician can test it before you decide to replace it.
