What this family is
This page profiles the NEM cooktop family: the four codes listed in the table below and nothing beyond them. They sit close together in build, so what follows holds across all of them.
What goes wrong on these models, and where each one is covered
- One element or burner will not heat or will not light — Note whether it is always the same position: one dead position points at that element, its switch or its igniter, several at once at the supply or the control.
- A gas burner clicks and will not light, or keeps clicking after it lights — Usually a wet, dirty or misaligned burner cap. Dry the area and seat the cap squarely; never hold a flame to it to help it along.
- The surface heats but will not hold a low setting — On electric or induction this is the control cycling; on gas it is the burner ports or the valve. Either way it is a fault, not a habit.
- An indicator or hot-surface light stays on after everything is off — The residual-heat indicator is doing its job while the glass is hot. One that never clears is a sensor or control fault worth reporting.
The problem classes, in the order they bring these units to a technician
- A burner or element that will not heat or will not light — First: it takes a cooktop out of service most often, and one dead position points somewhere very different from several.
- Ignition and spark faults on a gas burner — Second: ignition faults leave a burner that will not light or will not stop clicking — usually a cap and a clean.
- Touch controls that do not respond — Third: unresponsive controls are usually a wet panel or an engaged lock, which is why they rank above the surface.
- A damaged glass surface — Fourth and least common — but a cracked surface takes the appliance out of service immediately, whatever its rank.
Models in the NEM family — Each code here is pinned to a single build, so match the tag inside your door frame character for character.

Before anything is opened
Safety
Isolate the cooktop at the breaker before any panel, cap or trim is disturbed; a capacitor can hold a charge after the power is off. If you smell gas, do not touch a switch — leave the building and call the gas utility from outside.
What is an owner job on these models, and what is not
Cleaning, drying, reseating a burner cap, clearing a lock and resetting the breaker once are owner work on these models. Anything requiring the cooktop to be lifted from the counter is not — the connections underneath are a live supply or a gas line and often both in the same cavity.
