OTHER What happened to my motor?

[Ectron1]

Howdy,

I was out in the yard and noticed my dish turned almost full lock to the west. I pressed the manual button and it moved a couple degrees then stopped, now its completely unresponsive. The light is showing orange, reset does nothing. I've tried a different receiver but still no response.

Are there East and West buttons right ON the motor? If so, try those to see if you can get it to move.

It only has one button. A single press turns it west and 2 quick presses moves it east, It does neither. I'm not sure what phenomenon occurred to make it embark on its own mission, but its completely non responsive now.
Can I apply 18 vdc to the coax and power it that way or will that mess it up worse than it already is?

Measure the DC power at the motor on the coax coming from your STB. Horizontal polarity voltage? Vertical polarity voltage? Measure under load if possible.

Disconnect the coax at the motor that loops through to the LNBF? Does the motor move with the manual button with LNBF coax disconnected?

Clean all coax connections with DeoxIT, apply a cap of dielectric grease and retighten. Often a corroded fitting can cause problems with motors and movement.

Does the motor LED blink when a motor move instruction (DiSEqC) is sent from the STB?

12 - 19Vdc can be inserted directly to the motor STB port. Disconnect the STB. Positive polarity to the center stinger and negative to the shield.

I'll give these things a shot one evening this week and see what I find.

Thanks for the info.

I tried most of the above suggestions, but still no response from the motor. I took it inside and tried powering it on the bench and its dead. The light is orange not green and it does blink when i hit the manual button just no movement. I may take it apart at some point and investigate further.
I've been contemplating removing it and changing over to multiple lnb's anyway, so I guess this is the straw that broke the camels back lol

Sometimes the relays on the motor printboard get "stuck". Tapping on them releases that (temporarily). So maybe you can check that.

Thanks, I'll make a mental note of that.

I figured I'd give an update. Recently I had some time and took apart the motor to check it out, and sure enough the contacts on the eastbound relay were toast. I ordered a new pair from Digikey and its working like new again. Something i noticed though is with the motor removed the gear lash was set so tight it was difficult to turn even with a screw driver, possibly what caused such a load on the contacts? I eased the gear lash up a bit, so hopefully these relays will last a little longer than the originals.
