Garage Door Will Not Close

by Bill
(Rockwall, Texas)

We have a Legacy Garage door opener 1/3 HP, Model 496 CD/B. It works fine except in the extreme heat of 100 degrees or more when it will not close. The door starts to go down for about 6 inches and then returns to the up position. Can anyone assist us in what to look for?

Bill, it sounds like in extreme heat your safety sensors are moving just enough that they are no longer in alignment.

When they are aligned more precisely they should work at any temperature.
