DCS Grill Won't Ignite
Grill Won't Ignite is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Sea-level orifices that were never converted
Less oxygen for combustion means an unconverted appliance runs rich — yellow-tipping, sooting and slow recovery that all read as a failing valve.
A dirty or misaligned igniter
Debris or grease buildup prevents a clean spark, which is the single most common cause of ignition failure.
A faulty gas valve or regulator
Controls gas flow to the burner and can fail independently of the igniter.
Local conditions that matter here
At this altitude there is materially less oxygen for combustion, and appliances shipped with sea-level orifices run rich until they are converted. That shows up as yellow-tipping burners, sooting and slow recovery — symptoms that look like a failing valve and are usually a conversion that never happened.
