Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond as typing, researching and adding links takes me time to do so please be patient and often I will ask you questions to narrow down the issue to get is diagnosed correctly.

Can you take a picture of the switch that is buzzing and upload it here?

After a bit more research I know now it's the contactor that is buzzing. Strangely even with the power to the unit cut and the capacitor disconnected. I also noticed the contactor is stuck in the contacted position. My other unit when off the contactor is released.

AHHHHH yes the contactor is fried, I can see the burned up contact on the contactor. You need to replace that to get the unit working again. Here is a link to one.
