Whirlpool Whirlpool WFG505M0BS 5.0 cu. ft. Freestanding Gas Range MECH-BURNER Error Fix: Cooktop Burner Not Igniting

Error code MECH-BURNER on the Whirlpool Whirlpool WFG505M0BS 5.0 cu. ft. Freestanding Gas Range means: Cooktop Burner Not Igniting. One or more gas cooktop burners will not ignite. The spark igniter clicks but the burner does not light, or the igniter does not click at all. Clean the igniter electrode tip and the burner cap — grease, food debris, or moisture prevents a good spark. Ensure the burner cap is properly seated (misalignment prevents gas from reaching the flame ports). If one burner's igniter is dead but others work, the igniter for that burner may be cracked or the wire is disconnected. If no burners click, the spark module may have failed.
