Satellite elevation sensor

I would access the insides to measure the voltage. Might be a blown fuse not feeding it.

Have a wineguard DM4000 elevation sensor that isn't working.
It does not use a battery, is wired to coach. Is there a way to determine if the sensor problem is with the outside sensor attached to satellite dish or if it is the indicator mounted on the ceiling. Thanks

Correct answer above. Assuming you are seeing no display at all when you push the button you first need to see if you have any power. It's sometimes tied into the Winegard power supply wall plate. If you have power and no display then you will need to order a replacement.
As an aside, has it ever worked? What are you hoping to use it with? They don't have much functionality these days.
