Range Surface Burner Control Switch (8″ Element)

Restore precise heat management to your cooktop with this Factory Certified Infinite Switch. This component acts as the “brain” for your 8-inch surface element, regulating power to switch the burner on and off and adjust its intensity. If your burner is stuck on the highest setting (regardless of where the knob is turned) or refuses to heat at all, this switch is likely the cause of the failure.

Designed for high-performance ranges, this switch is rated for 8.9 to 11.0 amps, ensuring it can safely handle the voltage required for large heating coils. As a Factory Certified Part, it features the exact terminal layout and resistance calibration needed to match your appliance’s original wiring and control knobs.

Quick Info:

• Compatibility: Engineered for major range brands using 8-inch surface elements.

• Fixes Common Issues: Resolves “runaway” heat (stuck on high), burners that won’t turn on, and intermittent heating.

• Electrical Rating: Designed for 8.9A – 11.0A load capacity.

• Difficulty: Novice. Requires basic disassembly of the control panel.

Pro Tip: Before disconnecting the wires from your old switch, take a clear photo of the terminal markings (usually labeled L1, L2, H1, H2, and P). Use needle-nose pliers to transfer the wires one by one to the new switch to ensure the circuit is mirrored correctly.

Safety First: You must unplug the range or flip the house circuit breaker before starting. Range switches handle high voltage (240V), so ensuring the power is completely disconnected is critical for a safe repair.
