Safe checks
- Several zones dead? Reset the double breaker.
- One zone dead: watch it at high — any glow at all? A partial glow means a broken coil inside the element.
- Stuck on high: turn it off at the knob; if it still glows, turn off the breaker.
When to call
Any element that will not heat or will not turn down. A switch stuck on high is a fire risk — use the breaker until it is fixed. See LG range repair or LG cooktop repair.
