Induction Cooktop Not Turning On
Induction cooktops use high-power electronics and are commonly supplied by a 240-volt circuit, so the safe homeowner approach is limited to exterior checks. A blank display can come from a tripped breaker, child lock, power interruption, or failed control module. If the display works but the zone will not heat, incompatible cookware or a pan that is too small is often the answer. Do not remove the cooktop, lift the glass, or probe internal wiring: capacitors and high-voltage parts can remain dangerous after power is switched off. Before assuming a costly electronic failure, note whether every zone is affected, whether the display shows an error code, and whether the problem started after an outage, spill, or breaker trip. One failed zone often points to cookware detection or a localized control issue; a completely dead unit calls for careful supply and service evaluation. Photograph any code before resetting power, because it can disappear after the cooktop restarts and helps the technician bring the right part.

Common Symptoms
- Display is blank or the touch controls do not respond
- Cooktop beeps or shows a lock, pan, or error symbol
- One zone will not heat while other zones work
- Cooktop turns off shortly after starting
- Breaker trips, burning odor appears, glass cracks, or controls become unusually hot
Most Likely Causes
- 1
Tripped breaker or supply problem
A 240-volt cooktop needs both legs of its circuit. A tripped two-pole breaker, loose supply connection, or electrical fault can leave the display blank or partially powered.
- 2
Control lock or temporary control fault
Many models have a child lock or need a brief power reset after an outage. The exact unlock method varies by model, so use the manual rather than guessing at button combinations.
- 3
Incompatible or undersized cookware
Induction requires magnetic cookware and enough pan contact over the cooking zone. Aluminum, copper, glass, and some stainless cookware will not heat unless a magnet strongly sticks to the base.
- 4
Failed touch control, fan, or power module
A dead zone, repeated error code, or shutoff with correct cookware can indicate an internal cooling-fan, control-board, or inverter fault. These components need qualified service.

Quick DIY Checks
Turn the breaker off and seek qualified service for smoke, a burning smell, visible sparking, a cracked cooktop surface, liquid entering controls, or a breaker that trips again after one reset.
Do not remove the glass, access the junction box, or test internal wiring. Induction cooktops contain 240-volt circuits and capacitors that can retain a dangerous charge.
Keep pacemakers and other implanted-device concerns in mind: follow the device and cooktop manufacturer guidance before using induction equipment.
- 1Step 1 — Stop using the cooktop and turn its breaker off for burning odor, smoke, sparking, a cracked glass surface, water inside controls, or a breaker that will not stay on. Arrange qualified appliance or electrical service.
- 2Step 2 — If there are no danger signs, check the control lock and any displayed symbol using the model's owner manual. Wipe the cool, dry control area with a soft cloth; water or a pan over the controls can prevent touch input.
- 3Step 3 — Test one known compatible pan. Use a clean, flat pan that a magnet strongly sticks to, center it on the marked zone, and select a heat level. Do not use an adapter plate unless the manufacturer approves it.

Repair vs Replace
A compatible-pan or lockout issue costs nothing to correct, and many single-component faults are repairable. Replacement becomes more reasonable when a cooktop has a cracked surface plus expensive power-module damage or repeated failures outside warranty.
Est. Repair Cost
$120–$650 for diagnosis, fan, touch control, or common module repair
Est. Replacement Cost
$900–$3,500+ for a new induction cooktop plus installation

Frequently Asked Questions
- Why is my induction cooktop on but not heating my pan?
- The most common cause is cookware that is not magnetic or is too small for the zone. Try a flat pan with a magnetically responsive base centered on the marked cooking area.
- Can I reset an induction cooktop by turning the breaker off?
- A brief power reset can clear a temporary control issue. Use the model manual, and reset the breaker only once if there are no heat, odor, water, or damage signs. A repeat trip needs service.
- Is a cracked induction cooktop safe to use?
- No. Turn it off at the breaker and have it evaluated. Cracks can allow spills into energized parts and the glass can fail further when heated.
