Kenmore 91142702100 30" radiant counter unit Parts

On the Kenmore 91142702100 electric cooktop (30 inch radiant counter unit), we lift the glass top by first shutting off power, then removing the knobs and any mounting screws so the top can be raised for access to the surface elements and switches. Use the steps in the owner's manual for safe handling.

Before you start (safety first)

• Turn the cooktop controls to OFF.
• Shut off power at the breaker (radiant cooktops use high voltage).
• Wait until the surface is cool; the hot surface indicator can stay on until the glass cools to about 150°F.
• Protect the glass; do not pry with metal tools.
• Use cut resistant gloves if you will be working near sheet metal brackets.

How we lift the cooktop top (typical process)

1. Remove the knobs: Pull the cooktop burner knobs straight off the shafts (set them aside).
2. Locate the hold-down points: From below the counter cutout or from the front edge (varies by installation), look for screws or brackets securing the cooktop to the countertop.
3. Remove mounting screws/brackets: Keep screws organized for reassembly.
4. Lift the glass top carefully: Raise from the front edge and support it; do not strain wiring to the elements or indicator light.
5. Service the needed component: Common items under the top include surface elements, infinite switches, and the hot surface indicator.

Parts you may handle while the top is lifted

Symptom you are addressing	Common part involved	Example part on this model page
Burner will not heat or cycles incorrectly	Surface element control switch	Control element WB23M8
Hot surface light stays off or acts erratically	Indicator light	Cooktop indicator light WB25T10012
Burner does not heat but switch seems OK	Radiant surface element	Range radiant surface element, 8-in WB30T10045

Why it matters

Lifting the top the right way prevents cracked glass, pinched wiring, and misaligned seals. It also lets you accurately diagnose whether the issue is the radiant element, the control switch, or the indicator circuit.

On the Kenmore 91142702100 radiant glass cooktop, there is no keypad-style control lock to “unlock”. If the surface elements will not heat, the issue is usually power to the cooktop, a failed control switch, or a failed radiant surface element; use the 91142702100 owner's manual to confirm normal operation and control settings.

Quick checks before you assume it is “locked”

• Make sure the knob is fully in the OFF position, then turn it to a heat setting again.
• Verify the cooktop has power at the home breaker (many cooktops use a 2-pole breaker).
• Look for a hot surface light staying on; the cooktop can stay hot after you turn it off.
• Confirm you are using flat-bottom cookware sized to cover the heating area.
• If one burner works but another does not, focus on that burner’s switch and element.

What usually causes a “won’t turn on” symptom

In this model family, surface heating is controlled by an infinite switch (control element) and the radiant element itself.

Symptom	Most likely cause	What to check next
One burner dead, others work	Failed control switch or failed element	Swap knob positions (if applicable), then test switch/element wiring
Burner heats only on high or cycles oddly	Worn control switch	Inspect and test the switch contacts
No burners heat	Power supply issue or wiring problem	Check breaker, terminal block connections, conduit wiring

Parts that commonly fix “no heat” on a single burner

If diagnostics point to a failed control or element, these are common replacements for this cooktop:

• Control element WB23M8 (surface element control switch)
• Range radiant surface element, 8-in WB30T10045 (heating element)
• Cooktop indicator light WB25T10012 (if the indicator is not working correctly)

Why it matters

A cooktop that seems “locked” is often not a lock at all; it is a control switch, radiant element, or power issue. Correctly identifying whether the problem is isolated to one cooking zone prevents replacing the wrong part.
