Hob Repair

Built-in gas hobs are highly sophisticated appliances that integrate delicate glass aesthetics with high-pressure gas valves and electrical ignition systems. Unlike traditional stainless-steel gas stoves, repairing a modern glass-top hob requires specialized knowledge and strict adherence to safety protocols. If you are experiencing a persistent gas smell, yellow flames that blacken your utensils, or burners that refuse to stay lit after releasing the knob, you need immediate professional intervention. Our certified technicians at Kitchen Doctor are trained to handle complex gas and electrical issues simultaneously safely.

We diagnose and repair all premium hob brands, each known for unique challenges. For example, Bosch and Siemens hobs often feature heavy-duty brass burners that can suffer from discoloration and severe carbon clogging if liquids boil over frequently. If the auto-ignition continuously clicks (sparking non-stop even when turned off), this is a classic sign of moisture trapped inside the ignition switches (micro-switches) beneath the knobs—usually caused by accidental spills or vigorous cleaning. Our technicians carefully dismantle the glass top to dry or replace these micro-switches and the spark generator box, restoring perfect electronic ignition.

Safety is our absolute priority. When servicing brands like IFB, Prestige, and Carysil, we frequently encounter issues with the Flame Failure Device (FFD) or thermocouple. If a burner lights up but immediately goes out when you release the knob, the thermocouple is likely faulty or covered in soot. We clean the thermocouple tip or replace it with a genuine OEM part. Furthermore, we handle LPG to PNG (Piped Natural Gas) conversions by precisely changing the internal brass nozzles and recalibrating the air-gas mixture to ensure a hot, highly efficient blue flame.

One of the most critical aspects of our service is dealing with cracked or shattered glass tops. Due to thermal shock (placing extremely cold or oversized heavy pots on a hot burner), the tempered glass can explode. A cracked glass hob is extremely dangerous and must NEVER be used. We safely uninstall the appliance, cap the gas line temporarily, and procure the exact OEM replacement glass to rebuild your hob safely at your home.
