Customer Question

I tested the voltage from circuit board to the fan motor. Less than 1 volt
JA: Thanks. Can you give me any more details about your issue?
Customer: Fan motor won't come on. I am replying to an email from a technician already.
JA: OK got it. Last thing — HVAC Technicians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied).
