Hi. If you are certain that you wired it correctly, have the correct voltage, then it will sadly be that you have a factory faulty unit - in which case you will have to contact your retailer for an exchange or service under an in-warranty failure claim.

Sorry, but I have to ask these questions. You said you did all the troubleshooting so I assume these have been verified. Both fuses are good and NOT blown? The face plate is seated properly and securely? You have tried the reset button under face plate?

Assuming you have, try this. Connect BOTH power leads (yellow and red) together and run them directly to the battery. Make real sure the chassis has a good ground connection and run the black ground lead directly to the battery. The wiring connector is firmly and properly seated and none of the pins are bent.

If you have done all of these and still get only the fan the only thing left is an internal fault. Before you go any further and risk your warranty I would box it up and take it back to the retailer. Assuming you within their return window they should give you a new one.

While there talk to the installer techs and ask about the unit. See if they have any tips or can make suggestions. The only dumb question is the one that doesn't get answered...

Good luck.
