Hi everyone- range is making some funny noises, And was looking for some guidance before I order the part.

noise comes from both the oven and burners. from the oven it is somewhat intermittent and occurs at higher temps,( 450*). it can be described as humming or buzzing or singing and the tone fades when the burners are turned down and returns when turned back to high. You can also hear some air coming from one of the burners.

Pressure regulator? any thoughts are appreciated. thanks!
