Electric range makes a clicking or sparking sound near the cooktop

Symptoms

• Rhythmic clicking sound coming from under the cooktop
• Visible spark or arc near a burner connection
• Clicking speeds up or slows with the heat setting
• Burning smell along with a clicking or sparking sound

Likely causes

• CommonNormal infinite switch cycling on electric coil or radiant burnersInfinite switches cycle power on and off rapidly to simulate different heat levels, and a soft clicking at this rate is completely normal.
• PossibleLoose burner connection causing an arcing soundA coil burner that isn't fully seated in its receptacle can arc slightly during use.
• PossibleCorroded or damaged burner receptacle terminalsCorrosion at the connection point can cause poor contact and audible arcing.
• Less commonFailing infinite switch making an unusual buzzing or louder clickingA switch nearing failure can produce a different sound than its normal quiet cycling.

What to do

1. Listen closely to determine if the sound is a soft, rhythmic click (likely normal) or a sharper spark/pop sound (likely a connection issue).
2. For coil burners, remove the burner and its drip pan and check that it seats fully and securely into the receptacle.
3. Turn off power at the breaker and inspect the burner receptacle terminals for discoloration, corrosion, or damage.
4. Clean light corrosion from the terminals with a dry cloth or fine sandpaper if accessible, with power off.
5. Reinstall the burner firmly and test again, listening for a change in sound.
6. If sparking continues or you see a visible arc, stop using that burner and keep the breaker off until it's repaired.
7. Have a technician replace a damaged burner receptacle or infinite switch if cleaning doesn't resolve visible sparking.

Tools and parts

• Cloth
• Fine sandpaper (optional)

When to call a pro

Have a technician replace a burner receptacle or switch if you see visible sparking rather than normal cycling clicks.
