Garage Door Opener Maintenance: Preparing For 100-Degree Summers in Austin
Summer heat in Austin is no joke. As soon as that glorious window of seventy-plus-degree afternoons comes to a close and we’re slammed with day after day of triple-digit temperatures, everything you own starts to feel the effects: your air conditioner, the dash in your truck, your lawn and garden and, yes, your garage door system.
It doesn’t dawn on many homeowners that their garage door is the hardest-working door on their house, and it’s bolted to a motor that sits in probably the most unbearable room in your whole yard. Extreme temperatures can cause damage to your garage door opener.
Most people don’t realize that excessive heat can force your garage door opener motor to overheat, evaporate any lubricant built up on the moving parts, and expand metal components. All of these problems can lead to your opener malfunctioning or stopping dead in its tracks when you need it most. In my 17 years of experience, “when you need it most” is usually synonymous with some random August afternoon when it’s 105 degrees out, and your car is parked inside.
Thankfully, a little bit of preventative maintenance before our area reaches peak temperatures will go a long way. Preventative maintenance can help ensure you don’t have to stand out in the heat, sweat, and wait for a repair guy. Check out this simple summer maintenance checklist for your garage door opener that any homeowner can complete in just an afternoon.
How Central Texas Summer Heat Affects Your Garage Door Opener
Here’s how the science works. Hot air rises. A closed garage traps that hot air. On an extremely hot day, the temperature in your garage can reach well above the outside temperature. Most garage door openers are installed right up at the ceiling. This means your opener’s internal components are already operating under warm conditions before you even press the button.
When you force that hot motor to lift your heavy door multiple times throughout the day, it must work much harder. Not only does that heat have nowhere to escape, but your opener will wear out much quicker than normal. That motor that could have lasted you 5-6 more years can burn up prematurely, and what started out as a tune-up job can turn into a replacement. Reducing stress on your motor is one of the least expensive ways to prolong your garage door opener.
The attached garage in many Austin-area homes is located directly underneath a master bedroom or bonus room. If that garage gets super-hot all afternoon, then it heats up the floor of the bedroom above—which means your AC unit works overtime and your upstairs electric bill skyrockets. Cooling your garage (and garage opener) is not just about the door.
The Summer Maintenance Checklist
1. Clean and Dust the Motor Unit
Did you know dust is a great insulator? Not exactly what you want surrounding a motor trying to release heat.
- Issue: Dust and cobwebs accumulated on the opener housing prevent heat from escaping and force it to linger against the unit. This increases your likelihood of a motor thermal overload on extremely hot days.
- Solution: Use a dry cloth and wipe away dust from the motor housing and vents. It takes about two minutes and will help your opener beat the heat when you need it most.
2. Lubricate the Moving Parts (The Right Way)
Heat can kill lubricant. Low-quality lubes bake away in the Texas heat, abandoning your springs, rollers, and hinges to rub dry against each other.
- Issue: Dry, unlubricated parts create friction. Friction forces your opener motor to strain for every garage door lift cycle, creating more heat and wear and tear.
- Solution: Apply lubricant to your springs, rollers, and hinges to drastically reduce friction. Lubing your door is DIY garage door maintenance number one here in Austin. It’s frequently all it takes to keep a weak opener from requiring repair.
Pro Tip: Use a silicone-based lubricant or white lithium grease spray specifically made for garage doors. DO NOT use regular WD-40; it’s a wonderful degreaser, but it dries up in the heat, leaving your parts in poorer condition than when you started.
3. Check for Sun Glare & Hill Country Dust on Photo Eyes
There are two small safety sensors located down toward the bottom of your tracks, sometimes called photo eyes, that detect if anything is in the door’s path.
- Issue: Bright, low-angle Texas sunshine can create a glare right into the lens, which “blinds” the sensor and causes the door to reverse unexpectedly. Heavy spring oak pollen and fine Hill Country dust also accumulate quickly on those lenses with the same frustrating result.
- Solution: Clean both lenses with a microfiber cloth to wipe away built-up dust and pollen. Ensure both indicator lights next to the lenses are solid and not blinking. Blinking lights mean they are out of alignment.
Does the sun trigger your sensors every afternoon at the exact same time? The right sensor shade or a slight adjustment to your bracket will solve the problem right now.
4. Test the Battery Backup
Been in Texas more than a few summers? You know the routine: afternoon pop-up thunderstorms, overcrowded ERCOT grid losing power suddenly.
- Issue: There’s nothing worse than a dead or weak backup battery between you and that car stranded behind a closed garage door.
- Solution: Disconnect your opener from power (or switch off the breaker) and test your door while running solely on battery power. If it’s weak or non-responsive, chances are your battery is nearing the end of its lifespan (they should be replaced every couple of years), so replace it ASAP to avoid the next blackout.
5. Do a Quick Balance Test
Garage door openers shouldn’t have to do all the lifting. They simply guide your door up and down; your springs do all the heavy work.
- Issue: If your springs are worn or out of adjustment, your opener is lifting all that weight on its own, which can easily overheat your motor in the summer heat.
- Solution: With your door closed, pull the emergency release cord (“the red handle” that hangs down on your track) to disconnect your opener. Lift your door by hand until it is about halfway open, then release it. A balanced door will want to stay put. If it slams down or is extremely heavy, your springs need to be adjusted (alleviating a ton of pressure off your opener). Remember to pull the cord to reconnect your opener when you’re done.
A Quick Safety Word: Know When to Stop
Cleaning, lubricating, wiping down sensors, and testing your battery are all safe do-it-yourself jobs for homeowners. Please don’t hesitate to tackle those things yourself. There is, however, a distinct line that we DO NOT want you to cross.
Involve anything dealing with springs, cables, or internal mechanisms of the motor, and you’re playing with fire. Garage door springs are under extremely high tension, and a cable or spring can free-release in less than a second and seriously injure someone. We’re not trying to scare you; that’s just how it is.
If your balance test fails or something doesn’t feel right, let us know. We have safely repaired garage doors for over 15 years here at Two Brothers Garage Doors and will always provide you with an honest price and recommendation with no pressure sales. If it’s a simple repair, we will let you know. If it’s more, we will explain why.
