Strange problem Lift Master Formula 1

I have two garage doors driven by Lift Master F 1, identical.

The right one works fine year around -- good distance with a regular remote.

The left one works OK in the winter, with the distance slightly less.

Once it gets above 50 degrees, it starts acting up. Sometimes it opens, sometimes it takes 3 - 4 -10 hits of the button for it to work, even if I am standing right by the door in my car.

I also noticed that if I can't get the left door to open, I can hit the button on the remote for the right door, and right after that the left button, and it then works...

I am completely puzzled by this, despite electronics background. I've been living with this every since I bought the house, and it drives me nuts when I stand outside and can't close the door... Help!
