Gas leak when stove is off

I have a three year old maytag gas range that converted from natural gas to propane. Recently we have been smelling gas when we are not cooking. It seems to come from the oven, but we are not sure. Checked all the connections and no bubbles appeared. THe only other thing noticed is that when the oven is igniting, there is quite a loud ignition sound when the gas lights suring the baking time. Any suggestions?

sounds like its the gas valve inside the oven. it could also be that sense it was made for NG but converted to use PP that the gas is thiner and seaping through the gaskets on the valve. untill someone else comes along with a better idea i would turn the gas off to the stove at the valve on the line coming in from the wall when not in use.

Hello heidemarie and Welcome to the Do It Yourself Web Site and to the Gas Appliances topic.

There are or could be any one or more of possible causes for a gas odor. If the odor seems to be inside the oven, the likely possible cause is a tiny leak at the gas control valve.

That tiny leak is more commonly gas passing through the internally closed valve and out of the orifice. To determine if this is the location, remove the burner and soap test the orifice.

If the control valve is leaking when in the closed position, a tiny bubble will appear at the orifice. In this instance there is no choice but to replace the ovens burner valve with a new part.

Gas control valves are a non repairable part. Regardless of where any leak should happen to be. At the orifice or anywhere around the casing. Only exception would be at the gas inlet tubings fitting hex nut.

Based upon that loud noise you hear during baking and upon burner ignition, best guess is the valve is passing gas when in the off position. Replace the gas valve. Should resolve that problem.

Cautionary Reminder Note:
Before attempting any repairs, be sure to unplug the appliance from the wall receptacle power source first. Soap test all fittings to ensure there is no leaks anywhere.
