Hello, the company wants an $18 additional charge for a phone call, we can continue here if you wish, or I can submit that extra for the call.

Tell me if you have a multi meter or not, and if you can check power to the heating element in the humidifier and verify power from the humidistat to energize the control relay in the aprilaire 800

We can go from there
