How to Test a Gas Range Igniter & Oven Safety Valve
Igniter turning on, but no flame? Fix it with this guide.
Trouble turning on your gas stove? If your igniter is glowing but there is no flame, then one of two components in your range are at fault. These components are the “safety valve” and the igniter itself.
We’ve put together this video guide to help you learn how to test these two components, as well as a written guide below:
Igniter/Safety Valve Circuit Test
Take a clamp-on type ammeter, and attach it to the circuit to determine whether the igniter is working efficiently enough to open the safety valve. Clamp your meter onto the wire that either goes to the bake burner igniter or the bake burner safety valve. Turn on the bake function, and see what current is drawn. Typically your meter will show 2.8 – 3.0 amps for a normal current draw for a working igniter. If your meter is showing 2.7 or lower then you can assume that the igniter is not drawing enough current to actually ignite the flame, and therefore it won’t open the oven safety valve to allow the gas to enter the burner chamber. If this happens, it’s time to replace the oven burner igniter.
The Oven Igniter
For a “hot surface” or “glow bar igniter” you can test their power continuity using a multimeter. Simply insert both leads onto the terminals for the igniter and measure the resistance. If it shows resistance, it has continuity. No resistance? No continuity. Typically these will be somewhere between 80 and 175 ohms of resistance for a working igniter.
The Oven Safety Valve
To test the oven safety valve, measure between the two terminals, on the valve and look for continuity. The resistance here is low, but you should be able to detect 1 to 1.5 ohms. If your model uses a dual valve, one for the broil burner and one for the bake burner, then you will have two bi-metals and again you can test them for continuity using a multimeter. They also should be very low resistance and those would indicate that they're normal working oven safety valves.
If after performing these tests, you've determined that you need to replace your gas range's oven safety valves, oven igniter, burn igniter, or safety valves? Take a look at our large selection of oven parts.
