Why Summer Is the Worst Time for Garage Doors
Most garage door failures in Imperial Valley happen between June and August. The reason is simple: sustained heat above 110°F — hitting the metal components of your door system for 16+ hours every day — is extraordinarily stressful on springs, seals, lubricants, and opener components.
The springs that were fine all winter have been expanding and contracting through our dramatic day-night temperature swings since March. By June, they're at peak stress. The lubricants that were holding up are now dried out or cooked off by the heat. And the garage itself, if it's not properly sealed, becomes an oven — which affects the opener's electronics over time.
The Pre-Summer Checklist
1. Check Your Spring Tension
Disconnect the opener and manually move the door to the halfway-open position. Let go. A properly balanced door stays put. If it drifts up, the spring has too much tension. If it drifts down, the spring has too little — which means it's weakening. Either way, get it checked before summer.
2. Lubricate Everything
Springs, hinges, and rollers need to be lubricated at least once a year — ideally in late spring before peak heat. Use white lithium grease on the coils of torsion springs and on hinges. Use silicone spray on the tracks (not grease — grease in the tracks collects dust and becomes a problem). Don't use WD-40 anywhere on a garage door.
3. Inspect the Weather Seals
Look at the bottom seal on your door. It should be flexible and making full contact with the ground when the door is closed. If it's cracked, hard, or has gaps, it's letting hot outside air, dust, and pests into your garage. In Imperial Valley, a bad bottom seal is also letting monsoon water in when we get summer rain events.
Check the side seals too — the rubber strips along the door frame. If you can see light around the edges of a closed door, the seals need replacing.
4. Test the Safety Reversal
Put a 2x4 flat on the ground where the door closes. Press the button to close. When the door hits the board, it should automatically reverse. If it doesn't, the force limits need adjustment — and this is a safety issue, not just a maintenance issue.
5. Clean the Sensors
The photo-eye sensors at the bottom of the door tracks get dusty — especially in Brawley, Holtville, and the agricultural areas where dust is constant. A dirty sensor lens can cause the door to refuse to close (which it interprets as a blocked path). Wipe the sensor lenses with a clean cloth.
6. Check Your Opener's Ventilation
If your opener is mounted in a poorly ventilated garage that gets above 120°F, the electronics are running in conditions they weren't designed for. Consider adding a garage vent or leaving a door or window cracked during the hottest hours. Opener control boards don't like sustained extreme heat.
