Hello my name isXXXXX will assist you today.
Can you please give me the rest of the model number it should be 790.????????
I never recieved a answer, without the complete model number I can not give you the correct answers
I am taking a look at the service manual
Are you getting any other codes besides PF
is there anything else you can tell you have noticed when it does this to you?
Do they not click at all
Does the PF come up when you try to light them
I am attaching a service bulletin from Whirlpool in regards XXXXX XXXXX problem, I know yours is a kenmore but they build it for sears

I would also replace the spark ignitor if I were doing this repair at your home, since the noise is coming from the spark ignitor
Here is another direct link to the spark ignitor, you will find this unit behind the unit easy to change the bead I do not know but know it comes with instructions
