Induction Hob Not Heating Properly? We'll Diagnose It in Dudley

An induction hob that heats but won't heat properly is arguably more annoying than one that's dead — the pans warm eventually, or the zone works until you need full power, or it cuts out mid-cook. These partial faults have a wide range of causes, from the electricity feeding the hob to the electronics driving each coil, and the only honest way to resolve one is systematic diagnosis.

The range of possible causes

Weak or erratic induction heating can stem from several places. On the supply side, induction zones draw serious power, and a marginal circuit, loose terminal or degrading connection can cap output or cause protective cut-outs. On the appliance side, failing zone electronics, ageing sensors, control board faults or thermistor problems can make the hob reduce power, refuse boost, or shut a zone down. Cookware matters too: a warped or worn base can couple badly, heating slowly and unevenly in a way that mimics a hob fault.

There are also designed behaviours worth knowing — hobs reduce power when a pan is removed, limit temperature to protect the glass and electronics, and share power between zones on some models. An engineer familiar with the technology separates genuine faults from normal behaviour you may be misreading.

What the visit covers

We start with the supply: verifying the isolator, the circuit and the connections at the hob, because a supply fault explains symptoms that no amount of hob repair will fix. Then we test the hob itself — zone output under load, sensor readings, control response and error history. Diagnosis is completed and explained before any repair is quoted, so you know what failed and what fixing it costs before committing.

Deciding on the repair

Connector and supply faults are usually repaired economically. Failed zone electronics or control boards are a judgement call: sometimes sensible, sometimes better replaced, especially on older hobs where part cost approaches a new appliance. We quote parts separately from labour and give you the honest comparison rather than steering you toward whichever option pays us more. If a new hob is the right call, we can quote fitting it too.

Safety while the fault continues

An induction hob with degrading electronics or a poor connection can deteriorate further with use. If you notice burning smells, scorch marks, frequent cut-outs or the consumer unit tripping, stop using the hob and leave it off at the isolator until assessed. Never open the casing yourself — internal voltages remain dangerous after power-off.

One scope note: this page concerns induction and electric hobs. If your appliance is gas and the complaint is weak or uneven flames, that's the gas side of the appliance — Maintenance Men doesn't carry out gas work, so such faults should go to a trusted Gas Safe registered engineer, and we can advise on that referral.

Power sharing and other designed behaviour

Some induction hobs share power between zones — run two on boost and each is capped, which looks exactly like a fault if you don't know the model does it. Residual heat management and pan-size sensing cause similar confusion. Part of our diagnosis is separating these designed behaviours from genuine faults, because 'not heating properly' sometimes means 'working as designed, differently than expected'. Where that's the answer, we'll show you the behaviour in the manual and save you a repair you didn't need — an honest outcome we'd rather have than a bill.

Getting booked in

Contact us with the brand, model, how the symptoms behave — which zones, which power levels, whether cut-outs occur — plus any error codes shown. Those details let us plan the visit properly. Booking is by phone or website; the booking fee is paid when you book, the hourly rate depends on how soon you need the engineer, and the full cost of any repair is quoted and approved by you before work begins.
