Ignition Electrode (Spark Plugs)
Regularly inspect electrodes for carbon buildup or erosion. Use a wire brush or nylon tool to clean deposits without damaging the platinum/iridium tips. Verify gap spacing (typically 0.6–1.2mm) with a feeler gauge; misalignment reduces combustion efficiency. For high-mileage vehicles, replace electrodes every 48,000 km to prevent misfires caused by worn edges.
Grease and food residue often clog grill igniters. Disassemble the kit monthly, cleaning electrodes with isopropyl alcohol and a soft brush. Check battery contacts in push-button units—corrosion here is a leading cause of failure. Replace worn ceramic insulators to maintain spark integrity. Pro tip: Avoid using abrasive cleaners on metal electrodes to prevent pitting.
Hot Surface
Igniter (Furnaces/Ovens)
These silicon carbide or nitride components operate at 1,200°C+. Handle with care during cleaning—use compressed air to blow away dust, avoiding touch (oils transfer reduces lifespan). Inspect for cracks; even hairline fractures can cause ignition failure. In humid environments, seal connections with dielectric grease to prevent moisture-induced arcing.
Cross-Component Best Practices
- Environmental Protection: Use silicone boots on automotive electrodes to shield against oil spray.
- Replacement Timing: Barbecue igniters last 2–3 seasons; hot surface units require replacement every 5–7 years.
- Diagnostic Overlap: A multimeter tests continuity in all three systems—0.5Ω or less indicates healthy electrodes.
