How to Disconnect a Gas Range Safely Before Removal
Before an old gas range can be removed, it has to be safely disconnected from the gas supply. It is a short job when the shut-off valve works properly, but it is one to take seriously. If you have any doubt, call a licensed professional.
If you smell gas at any time, do not touch switches, phones or anything that could spark inside the house. Leave, then call 911 and your gas utility from outside.
What you need
- Two adjustable wrenches.
- A cap or plug rated for gas, sized to the shut-off valve outlet.
- Gas-rated thread sealant or yellow gas-rated PTFE tape.
- A spray bottle of soapy water for leak testing.
- A helper to move the range.
Step by step
- Turn off all burners and the oven and let the range cool.
- Unplug it. Most gas ranges have a 120-volt cord for the igniters, clock and oven light.
- Slide the range out carefully. Many ranges have an anti-tip bracket at the back foot; lift the back slightly to release it. Protect the floor.
- Close the shut-off valve. On a quarter-turn ball valve, the handle is off when it is perpendicular to the pipe.
- Disconnect the flexible connector at the valve, holding the valve still with one wrench while turning the fitting with the other.
- Cap the valve outlet with a gas-rated cap and sealant. An uncapped valve is a hazard if the handle is bumped.
- Check for leaks by spraying soapy water on the cap and valve. Growing bubbles mean a leak: tighten and test again. Never use a flame to check.
When to stop and call a professional
- There is no shut-off valve behind the range, or it will not turn.
- The connector is an old uncoated brass type, or the fittings are corroded.
- You are converting the kitchen from gas to electric and the line needs to be permanently capped.
Is the range really finished?
A burner that clicks without lighting or an oven that will not heat is often a simple igniter or electrode problem rather than a reason to replace the range. This explainer on a gas stove that clicks but won't light walks through the common causes. When it is time for the range to go, see our stove and oven removal guide.
Frequently asked questions
Do I need a plumber to disconnect a gas stove?
Not always, but if you are not comfortable working with gas fittings, if the shut-off valve is missing, stuck or corroded, or if you smell gas, call a licensed professional or your gas utility.
