We can't close or open the garage door remotely at night for many months. It works in the daytime but not at night. Weird. I can't find any answers. Batteries are good (we use two separate remotes. One came with the opener, and the other is programmed into the buttons in the car. Yet, neither work at night (or when it is dark). But why?

    If the remotes don't work, how do you open the door? Is the garage door opener outlet on a timer? Commented Dec 20, 2022 at 5:50

    Is the opener getting power all night, or might the circuit be on a timer -- or on a switch that isn't usually turned on after hours? Only other thought I've got is that there might be some kind of radio interference.

    Maybe the power connection is miswired somehow, so that when the garage lights are on, the opener gets no power. Commented Dec 20, 2022 at 12:34

Make sure you're not using LED bulbs in the openers. I had this same issue and that was the culprit for me. Swapping the bulbs out for LEDs designed specifically for garage door openers, or using CFL/Incandescents, solved the problem for me.

Did this change in behavior happen to correspond with changing light bulbs in the opener or anywhere garage area (such as accent lights, etc.)? Many LED light bulbs (especially inexpensive ones) cause radio frequency signal interference with the remote opener signal. To test, make sure there are no LED bulbs turned on anywhere near your opener and try it then. You can either get bulbs specially made to co-exist with garage door openers, or replace with CFL or the older incandescent bulbs.

  • sadly, most newer LEDs don't use SMPSs and thus won't cause interference (such bulbs tend to dim better and last longer) . my point is to just try the newest and cheapest bulbs you can get (think dollar tree) instead of more expensive garage-targeted bulbs.

  • The light 💡 in the opener itself hasn’t worked for a while now but we do have fluorescent lighting inside the garage but it’s rarely on. Commented Dec 21, 2022 at 20:17
