Jenn-Air JGS1450DS Slide-In Gas Range MECH-03 Error Fix: Burner Cap Misaligned

Error code MECH-03 on the Jenn-Air JGS1450DS Slide-In Gas Range means: Burner Cap Misaligned. A cooktop burner cap is not seated properly on the burner base, causing uneven flame, yellow flame, flame lifting away from the burner, or flame blowing out — remove the burner cap and base, clean both thoroughly, remove any food debris from the ports and the igniter well, and reseat the cap centered on the base; a tilted cap causes poor combustion and can produce carbon monoxide; clean the burner ports with a pin or toothpick to clear individual clogs; never use a wooden toothpick as it may break off inside the port
