In short
A gas burner that will not light, or an oven that will not reach temperature, is usually an ignition or a gas-delivery problem rather than a failed appliance. The checks an owner can safely make are limited but they resolve a good share of these. Establish what the appliance can still do before asking what has failed. Start at the cheapest check and work down.
What you actually see
- The oven never reaches temperature or takes far longer than it did — An oven igniter that has weakened, which is the classic slow decline on a gas oven.
- Some burners work and others do not — A per-burner problem rather than a supply problem, which narrows the search considerably.
- A burner clicks repeatedly and never lights — Ignition is trying and either no gas is arriving or the spark is not reaching it.
- NEAR MISS: nothing on the appliance works at all, including the clock — That is an electrical supply fault rather than a gas fault.
The causes in order of likelihood
- Burner ports or cap fouled by spillage — First, and first for a reason. It leads on these shared platforms because the burner hardware is common across the group and it fails in the same way on all of them. The most common cause of a burner that lights poorly or unevenly, and the one an owner can safely correct.
- Burner cap misaligned after cleaning — Second. A cap sitting a fraction out of position stops the flame crossing the ports and is the classic after-cleaning fault.
- Spark electrode wet, dirty or cracked — Third. A wet electrode after a spill or a wash clicks endlessly without lighting anything, and often dries out on its own.
- Flame supervision device not holding — Fourth. The sensor that proves a flame is present.
- Body: Ranked for a Brown, Royal Rose, Summit, Imperial and Brentwood gas range specifically. The order is the value here; the list on its own would be the same list anyone could write.
The diagnostic order
- Check whether other gas appliances in the house work — It separates a supply problem from an appliance problem in one step.
- Check whether the fault affects one burner or all of them — One burner is hardware; all of them is supply, regulation or ignition power.
- Look at the burner cap and ports on the affected burner — Misalignment and blockage are visible and correctable.
- Body: The order below covers only what can be done safely without touching a gas connection. Anything beyond cleaning and reassembly is a gas-qualified job.
What you can do now
- Turn the burners off and let everything cool completely — Nothing on this list is done on a warm range.
- Lift off the burner cap and head and wash them — Clear every port with a soft brush, dry them completely and refit squarely.
Tools: soft brush, cloth
- Refit the burner parts in their correct positions and test each burner — A cap a fraction out of place will not light properly.
- STOP at anything involving a gas connection, a valve or a regulator — Gas work is qualified work everywhere and there is no owner-side version of it.
Safety first
Safety
If you smell gas, 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. Unplug the appliance or switch off its breaker before removing any panel, and never attempt to adjust, disconnect or repair a gas connection, valve or regulator: that is qualified work in every jurisdiction.
When this becomes a service call
Call a qualified engineer for anything involving a valve, a regulator, a supervision device or a connection, and for an oven that preheats slowly or not at all. Call immediately, from outside the building, if you smell gas. Mention anything that changed in the kitchen just before the fault appeared.

What this page does not cover
This page is written for the appliance class rather than for one Brown, Royal Rose, Summit, Imperial and Brentwood family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and should be preferred over this one; the brand and appliance hub linked below routes to everything more specific that exists today.
