Air conditioner compressor wouldn't engage in rv. Called a mobile technician. Mobile technician found burnt and melted connectors on the control board. Technician stated the connectors used for 120v power were 12v crimp connectors and had burned and melted from the amperage. Technician stated that these used connectors were illegal to use for 120v. This is a safety concern and could result in a fire. Stated we were lucky the control board melted and didn't result in a fire and burn down the coach.
