replaced igniter, however this has not fixed the problem.
There is still a high pitched sound and the smell of gas. This smell is not as strong as it was before replacing the igniter and the burner will ignite as soon as the igniter comes on. The oven is not holding the temp you set it on, say 350. If you turn the oven off after 30 min of use and then right back on the oven temp may only be 200 degrees.
What is the difference between the control board and the thermostat in the back of the oven?
