Stove is leaking gas: causes, part cost
Prices checked 2026-08-28
A stove is leaking gas is most often a loose connection at the range problem - about 36% of reported jobs. Here is how to confirm it, what the part costs, and when to stop.
A stove is a collection of burners and switches. Faults are usually one burner's igniter or element, or a shared control – and one-burner faults are rarely worth replacing the whole stove over.
Stove is leaking gas is one of the most common repair searches there is. A gas or fuel smell is the one symptom on this site that is an emergency, not a diagnosis. Do not look for the cause first – shut things down first, then read on.
Before you call anyone: 30-second checks
- Do NOT switch lights, appliances or phones on or off near the smell – a spark is all ignition needs.
- Open windows and doors, leave the house, and call your gas utility or 911 from outside.
- Only after the utility clears the building should anyone inspect the appliance.
The likely causes, ranked
Loose connection at the range
About 36% of stove is leaking gas jobs come back to this cause. This is a component-level failure – the part itself has worn out or failed, which is why it sits on the ranked list rather than the free-check list.
How to confirm it: It is worth confirming with a multimeter or a visual check before ordering the part, and worth asking the shop if the part is returnable.
Typical fix: $80. This one is best left to a professional. You would be looking for a gas connector.
Danger: this cause involves gas, fuel or a serious electrical fault. Do not attempt it yourself – shut the unit down and call a licensed trade.
Cracked or kinked supply line
About 34% of stove is leaking gas jobs come back to this cause. This is a component-level failure – the part itself has worn out or failed, which is why it sits on the ranked list rather than the free-check list.
How to confirm it: It is worth confirming with a multimeter or a visual check before ordering the part, and worth asking the shop if the part is returnable.
Typical fix: $150. This one is best left to a professional. You would be looking for a gas supply line.
Danger: this cause involves gas, fuel or a serious electrical fault. Do not attempt it yourself – shut the unit down and call a licensed trade.
Faulty valve or regulator
About 30% of stove is leaking gas jobs come back to this cause. The gas or fuel side – supply, valve, regulator, carburettor – is where fuel stops flowing, and it is a licensed-work zone when gas is involved.
How to confirm it: Check the supply is on and the line is clear; for fuel units, check the fuel age and the carburettor if it has sat unused.
Typical fix: $250. This one is best left to a professional. You would be looking for a gas valve.
Danger: this cause involves gas, fuel or a serious electrical fault. Do not attempt it yourself – shut the unit down and call a licensed trade.
When to stop and call a pro
This is not a DIY item. Gas work is licensed for a reason; the stop line below is not a suggestion.
How to keep it from coming back
Gas connections age. A yearly service that includes a leak check on fittings and the valve train is the entire prevention program.
Bottom line: Stove is leaking gas is worth diagnosing before you call anyone – the free checks above catch a surprising share of cases, and the ranked list tells you what the part should cost if it is not one of them. Run the figures through the repair-or-replace test on this page before you authorise any work, and never pay for a diagnosis without getting the part name and the price in writing first.

What this should cost to put right
Across the causes listed above the repair runs $80 to $250. A quote far above the top of that range is usually a diagnosis of convenience - get a second opinion before you authorise it.
Repair it, or replace the unit?
This is the number people get wrong most often, and it costs them the most. Run the quote through the test - it uses the mid-point cost of the fix above against a new unit and the years this one has left.
REPAIR IT
The repair is 18% of a new unit and the appliance has roughly 6 year(s) of expected life left. Fixing it is the economical call. A new unit would save about $45/year in running costs, so keep repairing until that pays back in under 5 years.
Decision rule: repair when the fix costs under 50% of a replacement and the unit is under 70% through its expected life.
