The short answer
The rule first: if you smell gas, do not switch anything on or off, leave the building, and call the gas utility from outside. Everything else about a Conservator gas range is ordinary appliance work, and the classes below set out what turns up and where the detail lives. The ranking is the part worth reading twice.
What you are seeing and hearing
- A burner clicks but will not light — A clicking burner has power and spark; what it lacks is usually a clear path for the gas. Time it roughly, as the pattern matters more than the exact interval.
- The flame is yellow, lifting or uneven around the ring — Blocked ports or a misaligned burner cap, and it is a combustion question rather than a cosmetic one. It takes less time than reading about it.
- Clicking that will not stop, even with the burners off — Continuous clicking is an electrical nuisance with a cleaning cure most of the time. Rule it in or out before moving on, because the next check assumes an answer to this one.
- The oven will not hold temperature or bakes unevenly — A thermostat, sensor or bake-element class fault, and it is diagnosed with a thermometer rather than by taste. It is the sort of check a technician does first, for the same reason.
- Nothing electrical works: no clock, no ignition, no light — A dead panel on a gas range stops ignition, which surprises owners. Rule it in or out before moving on, because the next check assumes an answer to this one.
Causes, ranked for this appliance
- Wet, dirty or cracked igniters — Ranked high because the cure is usually drying and cleaning rather than a part. Confirming it costs less than assuming it, which is why it is worth the few minutes.
- Oven thermostat and temperature sensor faults — An oven that runs hot or cold is measured, not guessed: the sensor is the usual cause and the thermostat setting is the usual red herring. Time it roughly, as the pattern matters more than the exact interval.
- Spark module and electrical supply faults — It earns a place because the symptom points at gas and the cause is electrical. Confirming it costs less than assuming it, which is why it is worth the few minutes.
- Ventilation and combustion air — A kitchen that cannot supply combustion air, or an extraction system that has been blocked, changes how every burner behaves. Compare it with how the machine behaved a month ago rather than with how you expect it to behave.
What turns up, and how often
General guidance| Problem class | How often it turns up | Owner-fixable |
|---|---|---|
| Burner ports and caps | Routine | Yes: cleaning is owner work |
| Igniters and clicking | Common | Cleaning and drying, yes |
| Gas supply and valves | Occasional | No |
| Oven thermostat and sensor | Occasional | Measurement yes, repair no |
| Spark module and supply | Occasional | At the wall only |
| Ventilation and combustion air | Rare | Partly |
Based on: No measured sample: this ordering is engineering judgement for the appliance class, not a counted share of repairs.
What has to be off
Safety
The first step of every procedure here is the same: power off, at the plug or the consumer unit. If you smell gas: do not switch anything on or off, leave the building, and call the gas utility from outside. Nothing on this page asks you to disturb a gas connection, and nothing should.
When to stop and call
One rule decides it: you own the cleaning; a qualified technician owns everything that carries gas. Everything on the owner side of it can be done in an afternoon. Call the gas utility, not a repair company, the moment you smell gas, and make that call from outside the building.
