What a Georgia Summer Does to a Garage Door
Updated 2026-10 · McDonough, GA
The second peak
Searches for garage door repair in McDonough have two high points in a year. January is the biggest, driven by cold. June and July are the second, at nearly twice a quiet month. Summer failures are different from winter ones: fewer broken springs, more openers, sensors and doors that bind.
Sun in the safety sensors
The photo eyes near the floor either side of the opening tell the opener whether anything is in the way. On a garage that faces west, low evening sun in summer can shine straight into the receiving eye and blind it, and the door goes down, then reverses, at the same time every evening. The fix is often as simple as swapping which side the sending and receiving eyes are on, or fitting a small shade over the receiver. It is a common call and usually a cheap one.
Storms, surges and dead openers
Henry County summers bring afternoon thunderstorms, and with them power blips and lightning nearby. An opener's logic board is the most vulnerable part. The usual symptom is an opener with its light on that ignores the remote and the wall button, or opens and closes on its own. A board is often replaceable; on an old unit it may be time for a new opener, ideally with a surge protector on the outlet.
If the opener died after a storm, call with the brand and roughly how old it is. A local company can usually tell you on the phone whether a board is worth fitting.
Heat, the opener and the door
An uninsulated steel door facing the afternoon sun turns the garage into an oven, and an opener running in that heat works harder. Openers have thermal cut-outs and can stop mid-cycle on the hottest days, then work again later. That is a warning, not a fault, and an out-of-balance door makes it worse.
Wood and wood-composite doors swell in the humidity and can bind in the tracks or drag on the weather seal. Steel doors expand too, less so. Rollers and hinges that were merely dry in the spring start to squeal and grab by August.
What helps
- Lubricate hinges, rollers and springs with a garage-door lubricant, not grease
- Check the photo eyes are clean, tight and lined up
- Fit a plug-in surge protector to the opener outlet
- Test the door balance: released, it should stay at waist height
- On a west-facing garage, consider an insulated door at replacement time
Where to go next
Common questions
My door only reverses in the evening. Why?
Almost certainly sun shining into the safety sensor on a west-facing garage. Swapping the sensors side to side or shading the receiver usually solves it.
Does an insulated door really make the garage cooler?
Yes, noticeably on an attached garage that takes direct afternoon sun. It also makes the door quieter and stiffer.
