Use compatible cookware
Test with a flat magnetic pan of appropriate size centered on the selected zone.
Induction pan-detection guide • San Diego
Same-day Wolf Induction cooktop repair in San Diego, Mon–Sat 7 AM–6 PM. $99 service call, credited to the repair. 3-month labor / 1-year parts warranty. Licensed (A51423) and insured up to $1M. Family-owned and run by Viktor, owner and lead technician. Rated 5.0★ from 454 Google reviews. Call (619) 877-6701. An induction zone will not heat without compatible cookware and proper pan detection. A blinking control, one inactive zone, slow heating, intermittent operation, lock mode, showroom mode, power delivery, cooling, sensor, module, or communication issue may be involved.
Symptom context
Induction transfers energy through compatible magnetic cookware. Pan material, base size, position, control lock, and bridge-zone setup can prevent normal operation even when the display responds.
If every zone is inactive, incoming power or a global control state becomes more likely. If one zone fails consistently with known compatible cookware, zone-specific sensing, electronics, or connections need evaluation.
Owner-safe checks
Test with a flat magnetic pan of appropriate size centered on the selected zone.
Induction zones do not preheat empty. Place the cookware before expecting heat.
Follow the model’s owner instructions for control lock, auto-lock, or showroom indicators.
If there is no overheating or repeated trip, reset the dedicated breaker once and retest.
Record whether the same pan works on another zone without moving or opening the appliance.

FAQ
The cooktop may not be sensing compatible cookware, or the indicator may represent a model-specific control or fault state.
No. A compatible pan must be detected on the zone before heating begins.
Pan position, zone size, bridge settings, sensing, or a zone-specific module condition can differ. Record the exact comparison.
No. One controlled reset is enough. A recurring failure or breaker trip needs diagnosis.
The residential diagnostic is $99 and is credited toward an approved repair. Findings and the proposed repair are explained before work proceeds.
No. SHR, 5HR or SHOW means showroom mode, which lights the controls without heating. It is often left on after delivery or installation. Wolf's first step is turning off the breaker for about 10 seconds and restoring power. If the code is still there afterward, the setting needs to be cleared through the control menu or by a technician.
On CT models that pattern with an F7 code means the electronics hit 158°F and protected themselves. Long high-power boils make the most internal heat. Check that the ventilation space under the cooktop is clear and that the cooling fan runs. If the shutdowns continue on cool days too, the fan or the board's temperature sensing may be at fault.
Yes. Wolf's CI series shows error 3 when moisture or an object sits on the control sensor area, and the cooktop may beep or ignore input until it is cleared. Dry the glass completely, remove any utensils resting on the controls, and turn the breaker off for 30 seconds if the error does not clear on its own.
We do not recommend it. Induction boards carry line voltage and store charge, and the glass top cracks easily when lifted. Safe owner checks are cookware, lock mode, showroom mode, a breaker reset and a clear air path. Anything past that belongs to a technician working with the power verified off.
Local notes · San Diego County
Most of the time a Wolf induction zone that refuses to heat is not broken. The cooktop only energizes a coil when it senses a magnetic pan, and it stays dead while lock mode or showroom mode is active. Hold a fridge magnet to the pan bottom, look for a lock symbol, and check whether the display reads SHR, 5HR or SHOW. If all three check out and the zone still flashes or shuts off, the problem is heat in the electronics or a failed board, and that is where a technician comes in.
An induction cooktop is really a set of power boards with a glass lid. Those boards make heat of their own, and Wolf's CT series shuts them down with code F7 once the electronics pass 158°F (70°C). How close a kitchen runs to that limit depends on where it sits in the county. At Lindbergh Field the average August high is 77.3°F. In El Cajon it is 88.6°F, and the hottest late-summer day there typically reaches about 100°F. A tight inland cabinet install, especially one whose air path was blocked in a remodel, has far less margin. Near the coast the pressure comes from the other direction. The marine layer keeps air cool and damp from May through August, and Wolf's CI series throws error 3 when moisture or objects sit on the touch control area. Dust and pet hair are a countywide issue: the cooling fan under the glass pulls air through an intake that clogs over time, which raises board temperature on any day of the year.
Symptom: Power level blinks, the zone never heats, and it turns itself off after a short wait. Cause: The pan is not magnetic, is too small for the zone, or has a warped base that does not sit flat. Aluminum, copper and some thin stainless pieces will not register. Fix: Test with a magnet and try a known cast-iron pan on the same zone. If a good pan heats, the cooktop is fine and the cookware needs replacing.
Symptom: Every zone is unresponsive, or the controls light up but nothing heats. The display may show SHR, 5HR or SHOW. Cause: Control lock was left on after cleaning, or showroom mode was set at a store or during installation and never cleared. Fix: Release the lock per the use-and-care guide. For showroom mode, turn the breaker off for 10 seconds, then restore power and try again.
Symptom: Zones heat, then drop out mid-cook. F7 appears, most often during long boils or on hot afternoons. Cause: Board temperature passed 158°F. Usually poor ventilation beneath the cooktop, an install that ignored Wolf's clearances, or a cooling fan that has stopped. Fix: Let it cool and reset the breaker. If it comes back, we check the cooling fan, the air path and the install cutout before blaming a board.
Symptom: One zone or a pair of zones is dead with good cookware. CI models may show error 47. Cause: A failed induction generator (power) board, or on CI models a LIN communication error between boards, sometimes from a loose harness. Fix: We test the harness connections first, then the board that drives the dead zones. Board replacement is the most expensive repair on this cooktop.
Prevention on an induction top is mostly about heat and moisture. Keep the ventilation path below the cooktop open: do not stack pans or cleaning supplies in the drawer or cabinet directly under it if the install guide calls for airflow there. Wipe the glass dry after cleaning and never leave a damp towel across the touch controls. In homes with shedding pets, dust and hair gather at the cooling fan intake faster than most owners expect. After any cabinet work, confirm the installer restored the clearances listed in Wolf's instructions.
We start with the easy eliminations so you do not pay for parts you do not need: voltage at the cooktop, showroom and lock settings, and each zone with a test pan. Next comes the cooling fan and the space below the cooktop, because overheating complaints are often airflow problems. Only then do we open the unit to test boards and harnesses. Have the model and serial number ready (usually on the cooktop's underside or in the paperwork), plus the exact code or a short phone video of the display.
Touch controls, fans and harness faults are routine repairs and almost always worth doing. A power board is the costly one. On an older CT model, a failed generator board can approach the value of the cooktop, and that deserves an honest conversation. Keep in mind that a new cooktop may not fit the existing countertop cutout, which can turn a simple swap into stone work. Our $99 diagnostic is credited toward the repair, so you get a firm answer before deciding.
