I tested the igniter at. 95 ohms. Oven bake was not lighting, but broil was. 120 volts at plug from board. Once apart the oven decided to light, go figure. It takes about 75-80 seconds to light from press of start. Does my ohms sound right, and what is an acceptable light time? It has been slow to heat up to temp. Thanks.
ANSWER Ryan, A resistance reading of 95 ohms is in range, But a resistance test is not the best way to test an oven igniter. The best way to test the igniter is to use a "clamp on" amp meter TJMA-600CF. with the meter clamped around one of the wires, as the igniter glows, there should be a 3.2 to 3.6 amp draw, and at that point the gas valve bi metal switch should open and release the gas for ignition and flame. On avarage it should only take 30 to 60 seconds, if the igniter is operating properly and drawing the correct amperage. If you can't get access to a meter, replace the igniter, 95 % of gas oven temperature issues are do to a "weak" igniter.
