Garages and Carports - Legacy Overhead Door

Not sure if this is where to post my problem but here goes...Our legacy overhead door sometimes won't work when it is hot out. The remotes won't work as well as the wired switch in the garage. I can manually unhook the door and it closes very easily. The inside switch will then work and move the chain to the closed position and relock. It will open again normally but won't close again with out manually unlatching the door from the drove unit. When it cools down again it works fine. Every morning and evening works great but mid afternoon sometimes it's Tango Uniform. When the buttons are pressed no lights or motors running. I even blocked the sunlight from the safety sensors to see it that was the problem but no luck. I'm never home at that time and it's the wife who is about to shoot the thing off the garage ceiling. Any suggestions or help would be greatly appreciated

Don't want to mess with a pistol packing mama.
It does sound like the senors are border line on seeing each other. Most have a green LED light on one and red on the other.
The next time it happens, ask her to look at the senors and see if both lights are on and burning steady. If one is flashing, it can't see the other. Check for dirt or bugs on the lenses and move one or the other slightly until you get a steady light. If this is the problem, the door should now work.

Try moving both sensors away from the opening and place them directly in front of each other to test this for a couple days. Also, while you're doing this, check the wiring to the sensors for any pinches or cut shielding that could cause a short. Or, better yet, replace the wiring with some door bell wire. The default used by GDO companies is 22 gauge, but use 16 for better protection.
