KHHS179LSS Microwave where is the humidity sensor located

KitchenAid OTR microwave KHHS179LSS. Error code F3H says the humidity sensor is bad part #4393808 or sub #8206446.

Where is the physical location of the sensor ?
Does the unit have to be taken down to change it?
Is it really necessary to also replace the board part #8205813 which is $150 or more.

Appreciate all the advice I can get. My son is an electrician and he will do the work.
