Jenn-Air JMW2430IM 30 in Combination Microwave Wall Oven with True Convection MECH-02 Error Fix: Surface Burner Won't Light or Sparks Continuously

Error code MECH-02 on the Jenn-Air JMW2430IM 30 in Combination Microwave Wall Oven with True Convection means: Surface Burner Won't Light or Sparks Continuously. The cooktop spark igniter for a surface burner either will not produce a spark or sparks continuously even when the burner is lit — causes include: moisture in the burner switch (common after boil-overs), clogged igniter electrode/port (food debris covering the spark gap), cracked igniter ceramic insulator, dirty burner cap or base preventing proper gas flow, or a faulty spark module; clean and thoroughly dry the burner assembly including the igniter electrode and switch area; if continuous sparking occurs across all burners, moisture in the spark module or a shorted igniter is usually the cause
