What Texas Heat Does to a Driveway Gate Opener

Heat Shortens the Life of Electronics

Summer heat shortens the life of a gate opener's electronics, and the Texas Hill Country has plenty of it. A control box sitting in direct afternoon sun can run far hotter than the air around it. Boards, relays and batteries all age faster when they are hot, and a gate that worked all spring may start to misbehave in August.

Control Boxes Need Shade and Air

A simple shade over the control box can lower its inside temperature noticeably. Mounting the box on the shaded side of a post, or under an overhang, does the same. Ventilation helps too, but vents also let in dust and insects, so a screened vent is better than an open one. Small changes at installation save frustration later.

Batteries Dislike Extreme Temperature

Backup and solar batteries lose capacity in heat, and they wear out sooner. A battery tucked in a sun baked box may last half as long as one kept cooler. When a gate uses a battery, check its age every year and replace it before it fails, since a weak battery tends to give up on the hottest day.

Moving Parts Feel It Too

Grease in an operator thins in heat, and rubber seals can dry and crack. Chains and arms expand slightly, which can change the way the gate travels at the end of its stroke. Most modern openers compensate, but they are not immune. An annual look at the arm, chain or track keeps small problems from growing.

Sensors Can Misread in Strong Sun

Safety sensors that use light beams can be confused by low sun shining directly into the receiver. A gate near Devine Lake Park facing west may give false readings at sunset. Shielding the sensor with a short hood, or adjusting its position, usually clears the problem and keeps the gate from stopping for no visible reason.

A Simple Seasonal Check

Before summer, open the control box and look for dust, insects and signs of moisture. Test the battery, check the sensors and confirm that the gate travels smoothly through its full range. In Williamson County, a ten minute check before the hot season prevents many of the service calls that otherwise arrive in the worst weather.

Keep the Cover Clear and Clean

Keep the opener cover clear of dust, leaves and insect nests, and make sure its vents are not blocked. A clean, ventilated cabinet runs cooler through a Leander summer and lasts noticeably longer.
