The quick verdict
On a Conservator gas range the commonest noises are a burner clicking after it has lit and a roaring flame on a burner whose cap is out of place. Both come back to the burner head, the cap and how clean they are. The order below is what does the work on this page.
What you observe
- Clicking that continues after the burner has lit — Moisture or spillage on the igniter, which keeps the ignition circuit running. This is the cheapest information available on the machine.
- A whistling that changes with the flame setting — Airflow through the burner, often the cap seated slightly wrong after cleaning. If this is what you have, you are on the right page; if not, follow the near-miss line.
- Clicking on several burners at once — The ignition circuit itself rather than one burner, which is a technician question. Repeat it once if the answer is ambiguous rather than moving on with a maybe.
- ANY noise accompanied by a smell of gas — Stop. This is no longer a noise problem: leave the building and call the gas utility from outside. It is worth confirming twice before you act on it, since one observation can mislead.
Ranked causes for this machine
- Spillage or moisture on an igniter — First because it is the commonest cause of persistent clicking and because cleaning and drying fixes it completely. It is worth confirming twice before you act on it, since one observation can mislead.
- A cracked or worn igniter — A real fault that produces clicking without lighting, and it is a part rather than a cleaning job. If this is the cause, the evidence for it is usually visible rather than inferred.
- A failing ignition module — Clicking on several burners at once points here rather than at any single burner. Compare it with how the machine behaved a month ago rather than with how you expect it to behave.
- A gas supply or regulator issue — Last, and the reason the smell test comes first on this page: anything involving the supply is for the utility or a licensed technician. A cause in this position is worth eliminating before you spend anything.
What to look at first, second, third
- Smell first, before any investigation — If you smell gas, stop reading and leave the building. Every other check on this list assumes you do not. The position matters more than the name: work the order rather than the one you have heard of.
- Identify which burner makes the noise — One burner points at a cap, a head or an igniter; all of them points at the module. Doing it in this order is what keeps the diagnosis short.
- Look at the burner cap seating — A cap sitting proud or rotated changes the flame and the sound immediately. It sits above the more dramatic explanations because it is the one you are statistically likelier to have.
Owner steps, in order
- If you smell gas at any point: leave and call from outside — Do not switch anything on or off, leave the building, and call the gas utility or the emergency number from outside. Do not look for the leak yourself. Give it a moment rather than glancing; the thing you are looking for is not always obvious.
About 5 min
- Lift each cap and head, clean them, and refit them squarely — Caps and heads have a location feature. It is worth doing properly once rather than quickly twice.
Tools: clothAbout 25 min
- STOP: anything involving the supply belongs to the utility — Regulators, supply pipework and the connection behind the range are never owner work on a gas appliance. If you can only do one check, make it this one.
About 5 min
- The last owner step is the one above this line — What is left is diagnosis rather than inspection, and diagnosis needs instruments.
The safety floor
Safety
Power down at the breaker first, and treat the cabinet as live until you have. Never look for a gas leak yourself, and never test for one with a flame. Refit every cap and head in its proper place before the burner is used again.
The handover point
Here is the split as a technician would put it. On a gas appliance the owner boundary is drawn tighter than anywhere else on this site, and that is deliberate. The boundary is the same whether you are handy or not. Do not keep using a range whose burner valve feels gritty or loose.
