Brand: whirlpool
Model Number:SF370PEWN4
Main Symptom: loud noise when it lights in bake
What happens & when: When I turn the oven to 350 degrees bake I smell gas, there is a delay and then it makes a loud noise when lighting. It seems to take longer for it to light. I start to smell a little gas and then it makes a poof noise. Before it just lit and I never noticed it but now I smell a little gas and then it lights and it makes a noise. It heats up and works fine after it is on. I am wondering if it is the igniter.

Test the oven igniters to make sure that there is 3.2 to 3.6 Amps when lighting. This issue sounds like it would be a weak igniter that is causing the gas valve to open slower which could cause the noise.
