Understanding the Problem
When one or more electric burners (coil elements) fail to heat, heat only on low, or work intermittently, the cause can be a failed heating element, a defective control (infinite) switch, a bad receptacle/terminal block, or wiring/connectivity problems. On smooth-top (radiant) cooktops the issue can also be a failed radiant element, internal connector, or a control board/relay. Diagnosing the exact cause requires simple visual checks and a few multimeter tests. Many issues are repairable without replacing the entire range. For coil-style burners you can often confirm a bad surface element by swapping it with a working element of the same size. For more complex failures — repeated intermittency across multiple burners, or burners that click/flash but never reach temperature — the problem is more likely in the infinite switch, the element receptacle (socket), the terminal block, or the electronic control/relay. Always unplug the appliance or switch off its breaker before testing or replacing parts.
Common Symptoms
One or more burners produce no heat, only heat on low, heat intermittently, spark/click, or the burner indicator light behaves unusually.
Common Causes
- Failed surface (coil) element or radiant heating element
- Defective infinite/control switch that regulates burner power
- Damaged element receptacle (socket) or terminal block causing poor connection
- Wiring harness damage, loose wires or burnt connections
- Faulty main control board or relays (more common on glass-top ranges)
- Blown thermal fuse or temperature limiter on some models

Helpful Repair Tip
To quickly identify the faulty part on coil burners, swap the non-working coil with a known-good coil of the same size. If the problem moves with the coil, replace the element. If it stays at the same location, test the infinite switch and receptacle.
Frequently Asked Questions
Can I safely test and replace a burner element myself?
Yes — for basic tasks like swapping a coil element or replacing a receptacle/socket you can do it yourself if you turn off power at the breaker, remove the element and trim, and follow the manufacturer's instructions. Use a multimeter to check for continuity before buying parts. If you must access wiring, infinite switches, or the control board and you aren't comfortable with electrical work, hire a technician.
Why does my burner click or flash but not heat?
Clicking or flashing commonly indicates a failed connection, a weak element, or an electronic control trying to engage a faulty relay. On coil models it may be a loose connection at the receptacle or terminal block; on smooth-top ranges it often points to the control board or the radiant element failing. Inspect for burned connectors, test continuity of the element and switch with a multimeter, and check for error codes on digital panels.
