I was just reviewing your latest question on how the oven will heat to 175 degrees and needed to know if the thermastat could fix the problem and your suggestion was about the oven igniter lighting the gas properly....so on that note how can i tell if the igniter is not working that well either? i see the light come on and i dont hear the gas kick in or the heat get any hotter, so i assumed i needed to just replace the thermostat.

ANSWER Diana, The reccomended way to test for a weak igniter, is to use an amp probe, and check for a 3.2 to 3.6 amp draw on the igniter wires, while the igniter is glowing. You can also use a multi meter, and check for 3.2 to 3.6 VAC across the two wires at the safety valve, from the igniter. Approximately 95% of heat issues in a gas range or oven, is usually due to a faulty igniter, and is very seldom a thermostat issue. Based on your post, if you can't get access to either type of meter, replace the igniter. Heres some meter usage information, should you need it.
