Induction zone not working / no power to one ring
One zone does nothing while the others work — no display response, no fan-up, no heat — or it works briefly then cuts out.

Built-in hobs have changed more in the last fifteen years than any other kitchen appliance, and the fault profile has changed with them. A radiant ceramic hob is a simple thing: elements under glass, switched by energy regulators or touch modules. An induction hob is a piece of power electronics — each zone has a copper coil driven by an IGBT inverter at around 20–50kHz, generating an oscillating magnetic field that induces eddy currents directly in the base of a ferrous pan. Nothing under the glass gets hot except by conduction back from the pan. That difference matters for diagnosis. When an induction zone dies, the cause is usually the power module — an IGBT, its driver, or the cooling fan that keeps the module below its thermal limit — not the coil itself. Induction hobs are also intolerant of poor ventilation. They need the manufacturer's stated air gap beneath, and fitting one over a drawer unit without the correct clearance is the most common installation error we correct in new kitchens. Ceramic and solid-plate hobs fail more conventionally: radiant elements go open circuit, energy regulators burn out, and touch control modules die from heat or moisture ingress under the glass. Gas hobs fail at the ignition and flame supervision end — blocked ports, carboned electrodes, and thermocouples that no longer hold the gas valve open. All gas work is carried out only by a Gas Safe registered engineer; we will never touch a gas connection outside that. Across all three types, the most common single fault we attend is unresponsive touch controls, and a good proportion of those are not faults at all but a child lock engaged, a spillage bridging the sensors, or a residual heat lockout. It is a £90 call-out for the visit, the diagnosis and the labour, plus parts, which are quoted for your approval before anything is fitted. Twelve months parts and labour. Domestic hobs only.

Touch controls not responding
The panel lights up but pressing the controls does nothing, or the hob beeps continuously and shuts down without input.
Ceramic radiant zone not heating
A zone stays cold while the others glow normally, or heats only on the highest setting with no intermediate control.
Gas burner won't light or flame goes out
The igniter clicks but nothing catches, or the burner lights and then dies within seconds of releasing the control knob.
Induction hob shows an error code
A code such as E2, E4, F7, U400 or a flashing pan symbol appears and the affected zone or the whole hob stops working.
Hob trips the electrics
The RCD trips when the hob is switched on or when a particular zone is used.
Cracked or chipped hob glass
A visible crack, star fracture or deep chip in the ceramic surface, sometimes spreading gradually over weeks.
Induction hob buzzing, humming or clicking
A buzz or hum from the pan area at high power, a whirring from beneath the hob, or a rhythmic clicking at low settings.
Hob cuts out during cooking
The hob shuts down mid-use, sometimes with all zones going off at once, then works again after cooling.
Zone stuck on full power or won't adjust
A zone runs at maximum regardless of the setting, or steps through power levels on its own without being touched.
Gas burner flame yellow, lifting or uneven
The flame burns yellow or orange rather than crisp blue, lifts away from the burner ports, or burns unevenly around the crown.
Residual heat indicator stays on or never comes on
The H or dot symbol remains lit hours after cooking, or never appears at all even after a zone has been used at full power.
Is it worth repairing?
Hobs divide sharply by type when it comes to the repair decision. Gas and radiant ceramic hobs repair very well: elements, regulators, electrodes and thermocouples are cheap parts, so a £90 call-out plus one of them against a £250–£450 replacement clears the 50% rule comfortably. Induction is tighter, because the power modules are substantial electronic assemblies and much the most expensive part on the hob, against a replacement at £350–£700 plus fitting. A module repair on a hob under five years old is usually sound; on an eight-year-old budget induction hob it often isn't. Typical lifespans are 12–15 years for gas, 10–14 for ceramic and 8–12 for induction. In practice, though, cracked glass ends more hobs than component failure does, and on cheaper models the replacement panel genuinely can cost more than a new appliance. One thing worth weighing before replacing: swapping a hob means checking the worktop cut-out dimensions and the electrical supply, since induction typically needs a 32A cooker circuit rather than the 13A a gas hob's ignition ran from. Environmentally, a hob is a dense assembly of glass, steel and copper whose manufacture far exceeds its running impact, so repairing where the numbers allow is clearly the better choice. We'll be honest about which side of the line yours falls.

Brands we repair
We work on every major manufacturer, and our vans carry spares for the ones we see most in this area.
First-time fix
Our vans carry a wide range of hob spares so most jobs are finished on the same visit. If we need to order a part, it's usually fitted within a couple of working days at no second call-out charge.
What the call-out is
£90, covering the visit, the diagnosis and the labour. There is no integrated version of this appliance, so no surcharge applies. Parts are on top and quoted for your approval before anything is fitted.
Domestic only
We do not work on commercial or coin-operated machines.
Maintenance
Make your hob last longer
Water across Cambridgeshire, Bedfordshire and Hertfordshire runs around 280–320 mg/l. That limescale is the single biggest reason appliances die early here.
Clean sugary spills immediately while warm
Sugar, jam, syrup and fizzy drinks chemically etch hot ceramic glass and permanently weaken it, and etched patches are where cracks later start. Use a proper ceramic hob scraper at a shallow angle while the zone is still warm, not hot and not cold. This is the single most valuable habit for hob longevity.
Keep the ventilation under the hob clear
Induction hobs need the manufacturer's stated air gap — usually a minimum clearance to the drawer or oven below plus a ventilated void. A drawer stuffed with tea towels directly underneath will cause thermal shutdowns and eventually kill a power module. Check it periodically, not just at installation.
Use flat, ferrous pans of the right size
For induction, test pans with a magnet — if it doesn't stick firmly, the zone won't run. Match pan diameter to the zone within about 10mm, since an undersized pan wastes energy and can fail pan detection. A warped base reduces efficiency on any hob type and causes buzzing on induction.
Never use abrasive pads or bleach on ceramic glass
Scouring pads and abrasive creams leave micro-scratches that dull the surface and give food something to key into. Use a dedicated ceramic hob cream and a soft cloth, plus a scraper for baked-on residue. Bleach and caustic oven cleaner will attack the printed zone markings and the edge sealant.
Clean gas burner crowns and caps monthly
Lift them off once cool, brush the flame ports clear with a soft brush — never a needle, which enlarges the ports — and dry thoroughly before reseating. Make sure each cap goes back on its matching crown; mixing them up between burners is a common cause of poor flame picture.
Wipe the touch panel dry after cooking
Water films, wet cloths and spillages across the sensor area will lock the controls or make them respond randomly, and prolonged moisture eventually reaches the module underneath. Wipe the control area dry as a matter of routine and never leave a damp tea towel across it.
Don't slide heavy pans across the glass
Lift pans rather than dragging them, particularly cast iron and stoneware, which scratch ceramic surfaces and can chip the edges. Grit trapped under a pan base acts like sandpaper. Scratches are cosmetic at first but create stress points in what is a structural glass panel.
Never heat an empty pan on induction
Induction transfers energy directly into the pan base with nothing to absorb it, so an empty pan reaches extreme temperatures within a minute or two and will trigger the overheat protection or damage the glass. It's also the fastest way to ruin a good pan. Always add contents before switching on.
Questions
Hob repair FAQs
How much does a hob repair cost?
A £90 call-out covers the visit, the diagnosis and the labour on any hob, gas, ceramic or induction. What changes is the part: radiant elements, regulators and ignition components are cheap, induction power modules are substantial electronic assemblies, and a replacement ceramic glass panel is the dearest item of all. Every part is quoted for your approval first.
Is it worth repairing an induction hob?
Often yes, but the maths is tighter than for other appliances. A mid-range 60cm induction hob costs £350–£700 new plus fitting, so a £90 call-out plus a power module makes sense on a four-year-old hob and rather less on an eight-year-old budget model. We give you the part cost before you commit.
Can you replace cracked hob glass?
Yes, where OEM glass is still available for the model. We fit it with new seals and clips and inspect the elements, coils and wiring beneath while access is open. On some budget hobs the glass costs more than a replacement appliance and we'll tell you that straight away.
Do you repair gas hobs?
Any work on the gas side — burners, injectors, flame supervision devices, hoses and connections — is carried out only by a Gas Safe registered engineer. The electrical side, including ignition modules and spark circuits where these are separable, is standard work. Tell us the hob type when you book.
How long does a hob repair take?
Most repairs take 45 to 110 minutes in one visit. Elements, regulators, sensors and gas burner components are usually first-visit fixes. Induction power modules and glass panels are model-specific and typically need ordering, which takes two to four working days.
What guarantee comes with the repair?
Twelve months on parts and labour, directly with us. If the same fault returns within that period we come back at no charge. That applies equally to induction, ceramic and gas hobs.
Why did my new induction hob's module fail so quickly?
In our experience the usual reason is ventilation. Induction electronics need the manufacturer's specified air gap beneath, and hobs fitted tightly over a drawer unit or directly onto an oven without the correct clearance run hot and shorten module life dramatically. We check and correct the installation as part of the repair.
Which hob brands do you repair?
Bosch, Neff, Siemens, AEG, Electrolux, Zanussi, Whirlpool, Hotpoint, Indesit, Beko, Smeg, Miele, CDA, Lamona, Candy and Stoves among others. We work on domestic hobs only and do not service commercial or catering equipment.
How long should a hob last?
A gas hob typically lasts 12 to 15 years, a radiant ceramic hob 10 to 14, and an induction hob 8 to 12 — the induction figure being limited by its power electronics rather than anything mechanical. In every case, glass damage is more often what ends a hob's life than component failure.
Do you carry hob parts on the van?
We stock radiant elements, energy regulators, NTCs, cooling fans, spark electrodes and common gas burner components for the major brands, so many repairs are completed on the first visit. Induction power modules, touch control boards and glass panels are model-specific and ordered in.
