Answer Brian, A good "flat" oven hot surface ignitor will usually have a resistance reading of 40 to 90 ohms(+/- 10%) at room temperature. A resistance check isn't the best way to diagnose a weak or inefficient igniter. A "clamp on" ammeter is the easiest and best way to test the igniter. When the igniter is glowing for 30 to 60 seconds, there should be a 3.2 to 3.6 amp draw on the igniter wire. The second option would be to test the voltage across the terminals of the oven safety valve. With the igniter glowing, there should be 3.2 to 3.6 VAC across the two terminals of the gas safety valve. These are a bit more accurate and indicative of a "good" or "bad" oven igniter. Read More...
