Gas & Ignition

The Gas & Ignition category includes the parts that keep gas furnaces and combustion equipment safe, reliable, and working as designed. When ignition systems misfire or flame sensing fails, furnaces can experience lockouts, incomplete combustion, nuisance shutdowns, and unsafe conditions. This hub puts the proven parts pros reach for when restoring performance and safety.

Shop flame sensors that verify flame integrity, gas valves that precisely meter fuel, igniters to light burners reliably, and pressure switches (gas) that ensure proper combustion air and safe operation. Confirm compatibility by checking voltage, furnace model, burner configuration, and OEM specifications for your install or service call.

• Flame sensors to confirm consistent combustion and reduce false lockouts.
• Gas valves for accurate fuel control and safety compliance.
• Igniters designed for rapid and reliable ignition in gas furnaces.
• Gas pressure switches to ensure correct draft and safe burner operation.
• Field-tested parts chosen for durability and service performance.

Pro selection guide: match parts to your unit’s make and model, confirm voltage and connection type, and use OEM cross-reference tools to verify correct replacements before ordering. Proper gas and ignition parts prevent flame failure, improve start reliability, and uphold safety.

Pro tip: Always test flame sensors and pressure switches with appropriate meters and observe manufacturer’s service procedures — improper wiring or settings can mimic part failure.
