Gas oven will not heat, oven burner does not ignite, but hob burners work normally.

Safety first: Turn off gas supply to the oven section if possible. If you smell gas, ventilate and contact a gas engineer.

• Check ignition: Observe (through the viewing window if available) whether the oven ignition electrode sparks when the oven is turned on. If there is no spark, the ignition system or thermostat may be faulty.
• Clean burner: Once cool and with gas off, remove the oven base panel to access the burner. Clean burner ports and ensure no debris is blocking gas flow.
• Inspect thermocouple: Ensure the thermocouple tip is in the correct position relative to the burner flame path. If it is loose or damaged, it should be replaced by a professional.
• Professional diagnosis: Testing the oven safety valve and thermostat requires gas pressure measurements and should be done by a qualified technician.
