Electric Cooktop Element Not Heating or Locked

What usually causes it

• Element. Coil elements can blister or break. Radiant elements under glass can open.
• Infinite switch. The knob switch controls each element. A failed switch gives full heat, no heat, or nothing in between.
• Terminal block and wiring. Burnt or loose connections at a coil element receptacle stop it from heating.
• Control lock. Glass-top and induction cooktops have a lock to prevent accidental use. It often needs a long press to release.
• Pan compatibility (induction). Induction needs a magnetic pan. If a magnet will not stick to the bottom, the zone will not heat.
• Power. A tripped breaker, or half of a double breaker, can disable some or all elements.
• Control board. Touch-control cooktops can fail at the board or touchpad.

Cooktop element not heating

On electric cooktops, a failed element, switch or relay can stop one zone from heating.

Check first: Try another zone and check the breaker.

Cooktop stuck in control lock

Many cooktops have a lock that disables the controls. A stuck lock can also be a control board problem.

Check first: Check your manual for the lock key or hold time.

Safe checks you can do

• For coil cooktops, swap a working element into the dead position with the power off. If it heats, the element is bad.
• Look for a lock icon and hold the lock key for several seconds.
• Test induction pans with a magnet.
• Check the breaker.
• Do not use a glass cooktop that is cracked; see the next guide.

Parts that fail most often

• Coil receptacles burn out on heavily used front burners.
• Infinite switches wear and stick.
• Touch controls fail after liquids spill onto the panel.

How your home affects it

In older homes

Older homes in the Houston area often have smaller kitchens and laundry closets built for smaller appliances, older wiring, and shut-off valves that have not been turned in years. Older ranges and gas lines deserve a careful check, and some older kitchens share a circuit between appliances.

In new construction

Newer homes in the Houston area usually come with builder-grade appliances, and many early problems are installation issues rather than failed parts. A missing anti-tip bracket or a gas range that was never converted correctly can cause problems from day one.

In apartments and condos

In apartments, condos and townhomes around the Houston area, space is tight and the building often has its own rules for access, parking and shut-off valves. Compact and slide-in ranges are common, often on a single small circuit.

In garages

Plenty of homes in the Houston area keep a second fridge, a freezer or the laundry in the garage, where summer heat regularly passes 100°F. Outdoor and garage cooking setups see more heat, dust and humidity than kitchen ranges.

During storm season

Storm season around the Houston area brings power outages, surges and sometimes flooding, and appliances often show problems right after the lights come back on. Surges can damage oven controls and igniters. If a gas appliance was underwater, do not use it until it is inspected.

When to call for repair

• An element does not heat with a known-good element or proper pan.
• The lock will not release.
• You see scorching at a terminal or receptacle.

If a glass cooktop is cracked, turn it off at the breaker. If you smell gas, leave the house and call the gas utility from outside.
