Dryer making loud buzzing/screeching noise intermittently

Hello,

My dryer is making a loud screeching noise after running for about 1 minute. The noise continues (at various pitch levels) off/on throughout the entire cycle. It is drying the cloths fine, but there’s just this loud noise that occurs - goes away - then comes back. Something is definitely kicking on in the dryer which seems to be the catalyst for the loud noise.

Below is a link to a 30 second video of it going from being fine, to the buzzing noise (and then getting louder).

Any help/feedback is very much appreciated!

Thanks,

The noise occurs when the gas turns on and the dryer heater kicks on. Could it be the Solenoids going bad? The dryer still works fine (heat still works)…just the loud noise.
