Older DCS rangetops often fail to light or burn unevenly because of dirty ports, not broken parts. The way you clean them matters, because rough cleaning can enlarge ports or damage igniters.
What You Need
- A soft brush, such as an old toothbrush.
- Warm water and a little dish soap.
- A straightened paper clip or a port-cleaning tool for stubborn spots.
- Soft cloths, and time for everything to dry.
Step by Step
- Turn off the burners and wait until the rangetop is completely cool.
- Lift off the grates and the burner caps.
- Soak the caps in warm, soapy water for a few minutes, then scrub gently.
- Brush the ports on the burner head, clearing each one without widening it.
- Dry everything and let it sit for an hour in humid weather.
- Reseat the caps so they sit flat and straight.
Habits That Cause Trouble
- Spraying cleaner directly onto igniters.
- Using steel wool or a drill bit on ports.
- Putting caps back wet.
- Leaving boil-overs to bake on.
When Cleaning Is Not Enough
If a burner still will not light, burns uneven or clicks nonstop, the igniter or a valve may be the problem. We test those rather than guess. On a rangetop that is 10 to 20 years old, we also tell you if parts are scarce and what makes sense to repair.
For heavy buildup, do the job in two sessions rather than forcing it. Scrubbing hard on a cast cap can chip the coating, and a patient soak does the same work without the damage.
