Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Surface burner does not turn on
• Surface burner has intermittent dead spots
• Surface burner heat is erratic
• Surface burner remains on or will not turn off

Check Before Replacing

• Compare the affected burner with another burner of the same size, if available; if the problem remains with the same control position, the switch may be involved.
• With power disconnected, inspect the switch and wiring for visible heat damage or loose connections.
• Do not rely on continuity testing alone unless following the appliance-specific service documentation; the switch is generally replaced rather than repaired.
