Default LED landscape lights causing garage door opener not to work.

I have a strange problem. When I plug in the transformer for the landscape light the remote to open the garage door will only work if you hold it about 2' from the opener. When you unplug the lights it works halfway down the street. Its not on the same circuit but somehow its causing some kind of interference. Any idea of what I could check to see whats happening?

The wiring out of that transformer is usually 18-24v..or pretty low voltage. Have you tried to move it elsewhere and extend the leads to the lights and see if it still causes problems? Just lay the wiring across the yard with the transformer plugged into an extension cord. If you can isolate it to just the transformer then either moving it or enclosing it in a bell box of some sort might work...

i install & service lo volt landscape lighting and and have never had this problem. what brand txfmr is it? does it do it only when the lights are on or when the txfmr is plugged in and the lights are not on? some garage doors have diff freq setting, might try that.

Its this one. And it does it when its plugged in no matter if the lights are on or off.

I think the easiest solution here will simply be to go buy a different brand transformer with approx the same specs. Or you could try hanging a metal kitchen pot/pan over it to act as shielding.

Thats wild. I'm having a similar issue with mine. Have my new led landscape lights for about three weeks and for about three weeks I'm having trouble with my opener as well. Would never have thought in my wildest that my landscape lights have something to do with it.

I would lean towards the issue being noise going through the shared 120v circuit they likely are on. One of my garage door openers doesn't go down well (it reverses) when the house is on generator (16kw one). It's not voltage/power related but some type if noise on the AC line that disrupts it's internal circuits. You could try to plug the transformer in through a surge protector. They have some amount of impedance built into them that may shift the noise enough to fix the issue.
