Jenn-Air JMW2430IM 30 in Combination Microwave Wall Oven with True Convection MECH-01 Error Fix: Gas Oven Igniter Failure

Error code MECH-01 on the Jenn-Air JMW2430IM 30 in Combination Microwave Wall Oven with True Convection means: Gas Oven Igniter Failure. The gas oven igniter (hot surface igniter / glow bar) is weak or burned out — the igniter must draw sufficient amperage (typically 3.2-3.6 amps) to open the gas safety valve; a weak igniter glows orange/red but does not draw enough current to open the valve, so the oven does not light; symptoms include: gas smell without ignition, oven takes 15+ minutes to preheat, or oven does not heat at all; this is the single most common gas range repair; the igniter is located at the bottom of the oven cavity near the burner tube; replacement requires disconnecting the wire connector and removing 2 mounting screws; handle new igniters carefully as the silicon carbide element is fragile
