Craftsman Lawn Mower Ignition Controls Parts: Questions & Troubleshooting

Why does my Craftsman mower keep dying while I'm mowing?

A failing ignition coil loses voltage under load, cutting spark randomly. You'll notice the engine sputters, backfires, or stalls after 10–20 minutes of running. Ignition coils degrade from heat and vibration over time. Test spark with a plug tester; if there's no arc or weak spark, the coil is likely the culprit.

What's the safety switch and why does mine always trigger?

Craftsman mowers have safety switches on the seat and blade clutch that kill ignition if you dismount or disengage the cutting system. A worn switch contact can stick, preventing the engine from starting or causing unexpected shutdowns. Cleaning the switch contacts might work, but replacement ensures consistent safety detection.

My key won't turn in the ignition switch—is it broken?

Check for bent keys first. If the key is straight but the switch is stiff, the internal tumblers may be rusted or worn. Lubricating with penetrating oil sometimes helps, but a stuck ignition switch often needs OEM replacement. Forcing it risks breaking the key inside the cylinder.

How do I tell if the ignition coil is bad?

Unplug the coil wire from your spark plug and hold it 1/4 inch from metal while someone pulls the starter. You should see a bright blue spark jumping the gap. No spark, weak spark, or inconsistent ignition means the coil is failing. Genuine Craftsman coils are calibrated for your engine's voltage system.
