Common Symptoms & Causes

If you notice any of these symptoms, it’s likely that your gas burner igniter is clicking continuously on your KitchenAid KSDB900ESS even after the burner knob is turned off.

• The igniter on one or more burners keeps clicking after the knob returns to the OFF position
• A rapid, repetitive ticking sound persists for several minutes following burner shutoff
• The clicking stops only after unplugging the range from the wall outlet
• Clicking occurs on the left front or right rear burner specifically, even with surrounding burners off

These issues usually stem from moisture or food debris contaminating the igniter module, a worn spark electrode, or a faulty igniter switch that fails to open the circuit fully after shutoff.

Safety First

• Unplug the oven from the power outlet before starting any repair — never work on a live appliance.
• Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
• Take photos with your phone before disconnecting any wiring harnesses or connectors.
• Work in a well-lit area with enough floor space to lay removed panels flat.

Tools & Parts Needed

Essential Tools

• Phillips #2 screwdriver
• ¼” nut driver
• Multimeter
• Work gloves (heat-rated)
• Flashlight

Replacement Parts

• Spark/igniter module
• burner cap and head set
• Phillips screwdriver
• multimeter

Step-by-Step Repair Instructions

Step 1

Before you start any work, unplug the range from its power source. A gas igniter that keeps clicking after the flame is lit is almost always caused by moisture or food debris inside the igniter housing sending false signals to the spark module. By working with the range unplugged, you eliminate any risk of accidental sparking while you clean and inspect the components. Never attempt this repair with the range energized, even though the issue may seem minor.

Step 2

Remove the burner grates by lifting them straight off, then take off the burner caps and burner heads from their mounting studs to access all surfaces that collect grease and moisture. Wash each component thoroughly with warm soapy water and a soft brush, paying close attention to the slots and ports where debris hides. After cleaning, dry everything with towels and allow at least two hours of air drying before reassembly. Incomplete drying is a common reason for the clicking to return immediately after cleaning, so take your time with this step.

Step 3

Visually inspect the ceramic insulator on each igniter electrode, looking for hairline cracks or chips in the white ceramic collar surrounding the tip. A cracked insulator allows the electrical charge to ground out against the burner body instead of jumping to the cap, which produces continuous random clicking even when the burner is off. If you find any electrode with a cracked or chipped insulator, it must be replaced, as cracks cannot be repaired.

Step 4

Restore power and test the spark module by pressing each burner knob to the ignite position and observing whether every burner produces a spark. If all four burners spark normally, the module is functioning correctly, and your problem was debris-related, so you can proceed to reassembly. If one specific burner fails to spark at all, that burner’s electrode or the module itself has failed and needs further diagnosis.

Step 5

If one burner will not spark after cleaning, replace the spark module W10884547, which is located behind the control panel and secured by two Phillips screws with a wiring harness connector. Take a photograph of the harness orientation before unplugging it to ensure you can reconnect it correctly. Handle the new module by its edges to avoid damaging the circuit board. A failed module will typically cause one burner to go completely dead while leaving the others unaffected, distinguishing it from a debris or electrode problem.

Step 6

Reassemble the burner heads first, then seat each burner cap flat and centered on its head before replacing the grates. A cap that is even slightly tilted will hold the electrode gap at the wrong distance and trigger constant clicking. Press down gently on each cap and confirm it sits level with no wobble before restoring power. Taking an extra thirty seconds to verify proper cap alignment here will save you from having to repeat the entire cleaning process.

Where to Buy Replacement Parts

When to Call a Professional

If the issue persists after completing all steps above, the problem may involve a failed main control board, a defective temperature sensor or high-limit thermostat, or wiring that requires specialized diagnostic equipment. In this case, it’s best to contact a licensed appliance technician. On gas models, do not attempt any work on the gas valve, burner orifices, or supply line—this work is restricted to a licensed gas fitter in most jurisdictions.

How Much Does This Repair Cost?

DIY replacement parts for a faulty igniter or spark module on the KitchenAid KSDB900ESS typically run $15–$65. A professional service call for the same repair usually costs $150–$300 once you factor in labor and diagnostic fees. Tackling this repair yourself can save you $100 or more while restoring your cooktop quickly.

Frequently Asked Questions

Why does my KitchenAid KSDB900ESS burner igniter keep clicking after I turn off the flame?

Moisture or food debris trapped around the igniter is the most common cause, triggering continuous sparking even after shutoff. Clean the igniter cap and surrounding area thoroughly with a dry cloth to resolve it.

Is it safe to keep using the range while the igniter is clicking?

While it’s generally safe short-term, persistent clicking can wear out the igniter module quickly. It’s best to address the issue promptly to avoid a costlier repair later.

Do I need to replace the igniter switch or just clean it?

Start with a thorough cleaning before considering any replacements, since debris is often the primary culprit. If clicking continues after cleaning and drying, the igniter switch likely needs replacement.

The Igniter Module That Stops the Post-Shutoff Clicking on This KitchenAid

If you’ve cleaned the spark electrode and burner cap and the clicking persists after you turn off the burner, it’s likely that the igniter module has failed—and this is the exact OEM replacement for the KSDB900ESS that will end the issue.

What works

• Direct fit for the KSDB900ESS with the W10884547 part number—no guessing or cross-referencing required.
• Eliminates the phantom clicking completely when the module is actually the source, not just the electrode or cap debris.
• Swap takes about 10 minutes once you’ve identified the faulty module; connector unplugs, two screws, and you’re done.

What doesn’t

• Won’t fix the problem if the clicking is actually caused by moisture on the electrode or a worn igniter switch—test and clean first to rule those out.
• This is a larger expense than a cleaning kit or cap replacement, so confirm the module is actually faulting before ordering.

I’ve seen plenty of DIYers order the module first and find out the problem was just gunk on the electrode—wasting money and shipping both ways. Test the electrode with a multimeter or do a thorough cleaning with white vinegar and a toothbrush before committing to the module replacement. Once you’re certain the module is dead, grab the KitchenAid KSDB900ESS gas igniter module W10884547 replacement.
