Gas Cooktop Repair Guide: Safe Troubleshooting for Seattle Homeowners

Gas cooktops are reliable workhorses—until an igniter starts clicking nonstop or the flame won't light evenly. Before you keep cooking, a few quick checks can tell you whether it's a safe DIY fix or a job for a licensed gas cooktop repair technician. This guide covers the most common issues we see across Seattle and King County, with safety always first.

If you smell gas, stop and act first

A faint gas odor after lighting a burner is normal for a second or two. A persistent smell is not. If you smell gas:

• Turn every burner knob to OFF.
• Do not flip light switches, plug in devices, or use anything that could spark.
• Open windows and leave the home.
• From outside, call Puget Sound Energy's 24/7 emergency line at 1-888-225-5773, or 911.
• Once the leak is cleared, call a licensed gas appliance repair company to inspect the cooktop before using it again.

Igniter clicks but the burner won't light

This is the #1 call we get for gas stove troubleshooting in Seattle. The spark module is working, but no flame is catching. Common causes:

• Burner cap is off-center—lift it and reseat it squarely on the base.
• Food debris or grease is blocking the burner ports—clean with a soft brush once the cooktop is fully cool.
• Moisture from a recent spill or cleaning—dry the burner head and let it air out for 15–20 minutes.
• Gas supply was shut off—confirm the shut-off valve behind or below the range is fully open.

If the clicking continues after all four checks, the spark electrode or igniter switch may be failing. That's a repair we handle every week—don't keep cycling the knob, which can wear the switch faster.

Burner clicks even when no knob is turned

Phantom clicking is almost always moisture trapped under a burner cap or a stuck igniter switch. Wipe the cooktop dry, remove the burner caps and heads, and let everything air out. If it's still clicking after an hour, unplug the cooktop (or flip the breaker) and call for service—continuous sparking can damage the spark module.

Weak, uneven, or yellow flames

A healthy gas flame is steady and mostly blue with a small inner cone. Yellow or orange flames mean incomplete combustion—the burner isn't getting the right air-to-gas mix. This wastes fuel, leaves soot on pans, and produces more carbon monoxide.

• Clogged burner ports—clean with a straight pin or soft brush (never a toothpick that can break off).
• Burner head seated unevenly—lift, realign, and reseat.
• Wrong orifice for fuel type—common after a propane-to-natural-gas conversion. This needs a technician.

Gas smell only when a burner is on

If you only smell gas while the burner is lit, the flame may be lifting off the burner or the orifice may be partially blocked. Turn the burner off, let the cooktop cool, and inspect the burner head for debris. If the smell returns the next time you cook, stop using that burner and schedule a service call—running a burner with poor combustion is a carbon monoxide risk.

Knob is stuck, loose, or won't release gas

Gas valves get stiff over time, especially from cooking splatter that hardens around the stem. Don't force a stuck knob—a broken valve stem turns a $200 service call into a much larger one. A technician can clean and re-grease the valve with the correct high-temperature lubricant.

When to call a Seattle gas appliance repair pro

Call right away if you notice any of the following:

• Persistent gas odor, even faint, when burners are off.
• Igniter clicking that doesn't stop after cleaning and drying.
• Flames that stay yellow or orange after cleaning.
• A burner that lights but won't stay lit when you release the knob.
• Any damage to the gas line, regulator, or shut-off valve.
