Odd aerial issue(s)

[Mikey637]

Hey guys, got an odd aerial issue. It goes up no problem (apart from the fact it keeps trying to power it for another 10-15seconds) but won't go back down, if I give it a gentle nudge it'll go down absolutely fine though!

What could be causing these issues? I'm thinking wiring on the aerial not stopping at full mast and something broken stopping it going down?

Cheers, Mikey.

I'd hazard a guess that the teeth on the rack inside the aerial mast have worn at the raised position. The reason the motor continues to run on is that it looks to see a load (when it's raised or lowered) in order to know that it's at the correct position and then shuts off.

As you nudge it, it drops sufficiently to re-engage the teeth of the rack with the pinion and then drive it down. A new mast is about £30-40 and not terribly difficult to fit.
