What this family is
the NGMP family covers the Bosch gas cooktops whose model numbers begin NGMP, listed below. On gas cooktops of this kind the recurring complaints are burners that will not light or will not stay lit, flames that look wrong, and igniters that keep clicking - and the first rule on all of them is what you do if you smell gas.
What goes wrong on these models, and where each one is answered
- A smell of gas at any time — Not a symptom to investigate: leave the building without switching anything on or off, and call from outside.
- A burner that lights and then goes out on its own — Usually a cap seated off its pins or a blocked port. Covered in the ranked list on this page.
- Flames that are yellow, uneven or lifting off the ports — Clean the head and cap first; a flame still wrong afterwards is a licensed job.
Problem classes in order on the NGMP family
- Burner will not light or will not stay lit — First on the NGMP family. A burner cap seated slightly wrong, a port blocked by boil-over, or a wet igniter explains most of it, and all three are cleaning jobs. — Owner: Often yes
- Igniter clicking continuously — Second. Usually moisture or debris around the igniter after a spill or a clean, and it often stops once everything is properly dry. — Owner: Often yes
- Flame that looks wrong — Third: yellow, lifting, or uneven around the ring. Cleaning fixes some of it; anything that persists is a combustion question and a technician job. — Owner: Partly

What is owner-fixable on these models
Cleaning burner heads, caps and ports, drying an igniter after a spill and reseating a cap are owner work on these cooktops. Anything involving the gas supply, the valves, the regulator or a flame that is still wrong after cleaning is a licensed job, not a repair to attempt.
Before you work on one of these
Safety
If you smell gas: do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside. Do not look for the leak yourself.
