Customer Questions and Answers for Infinite Switch (Top Burner Control) by Whirlpool

Replacement infinite switch for an electric range or cooktop top burner that controls heat from low to high, restoring variable temperature control for a single cooking element. What it does:

• Regulates power to one top heating element so the burner responds to low-to-high knob settings.
• Replaces a failed control causing the burner to not heat, to stay stuck on one setting, or to cycle unpredictably.
• Restores gradual temperature changes for simmering and high-heat cooking when the original switch is worn or intermittent.
• Matches factory terminal and mounting locations for a like-for-like swap.

• Disconnect electrical power at the breaker before servicing the appliance.
• Access typically requires removing the cooktop or back panel; keep track of fasteners and brackets.
• Confirm terminal/connectors match the original switch before connecting; do not force mismatched connectors.
