Before / After
A homeowner in Weston reached out to iFixExpress after noticing that the right front radiant element on their glass cooktop refused to turn on. The remaining burners functioned fine, but turning the right front control dial produced zero heat.
Diagnostic Procedure
When an electric cooktop burner fails, the root cause usually boils down to a burned-out heating element, loose wire connection, or a defective power regulator switch (also known as an infinite switch). I arrived on-site in Weston with standard OEM components ready for diagnosis and repair.
1
Safety Isolation: Disconnected power to the cooktop at the main circuit breaker panel before accessing internal wiring.
2
Element Continuity Test: Accessing the underside of the glass panel, I tested the radiant element with a digital multimeter. The element showed correct coil resistance, confirming it was physically intact.
3
Switch Voltage Inspection: Checked the infinite switch controlling the right front burner. Internal contacts were burned and failed to bridge electrical current to the element output terminals when turned ON.
The Repair & Replacement
With the broken power regulator identified as the culprit, I removed the control knob and bezel to detach the failed switch. I installed an original equipment manufacturer (OEM) energy regulator switch to ensure exact voltage duty-cycle matching for the cooktop's radiant element.
Technician Insight: Power regulators cycle high-voltage current on and off to maintain selected cooking temperatures. Installing non-OEM or incorrect aftermarket regulators can lead to erratic surface heating or thermal shock damage to ceramic glass tops.
Wiring leads were connected using heat-resistant insulated spade terminals. The cooktop control housing was securely reassembled, and main breaker power was restored for functional verification.
Testing & Verification
I tested the right front burner across low, medium, and high settings. The element glowed red quickly and cycled smoothly according to knob adjustments. The entire repair was completed in 1 hour during the initial visit.

Frequently Asked Questions
A power regulator (or infinite switch) controls the electrical current sent to a surface element. It rapidly cycles power on and off to maintain the requested temperature level, from low simmer to intense boil.
If a burner stays on high heat regardless of knob setting, or fails to heat at all while showing good continuity on a multimeter, the switch is usually at fault. If there is no continuity through the coil, the heating element itself is burned out.
Yes. iFixExpress stocks common OEM infinite switches and cooktop regulators on our Broward County service vans, enabling us to complete most repairs in a single 1-hour visit.
OEM power regulators match the precise cycling intervals and amperage demands of your cooktop. Generic switches can cause improper temperature regulation or pose electrical safety hazards.
