Summer heat brings unique challenges for your garage door system. High temperatures can affect everything from the opener's motor to the door's weatherstripping. With proper preparation, you can prevent breakdowns and keep your door operating smoothly all summer long.
Garage doors and their components are designed to handle temperature fluctuations, but extreme heat accelerates wear:
Metal Expansion: Steel and aluminum doors expand in heat, potentially causing binding or misalignment. This is especially noticeable if your tracks weren't properly installed with expansion allowances.
Lubricant Breakdown: Standard lubricants can thin or evaporate in high heat, leaving metal components unprotected and increasing friction.
Opener Strain: Motors work harder when temperatures rise, leading to potential overheating. Many modern openers have thermal protection that shuts down the unit when it gets too hot.
Weatherstripping Degradation: Rubber and vinyl seals become brittle with repeated heat exposure, losing their flexibility and effectiveness.
Torsion and extension springs carry tremendous tension. Heat causes metal fatigue more quickly, so look for signs of wear like gaps in the coils, rust, or visible stretching. Never attempt spring repairs yourself—the stored energy makes this extremely dangerous.
Apply a garage door-specific lubricant (not WD-40, which is a cleaner, not a lubricant) to: - Roller bearings - Hinges - Spring coils - Track surfaces - Opener rail
Use a silicone or lithium-based lubricant that won't thin in heat.
Disconnect the opener and manually lift the door to waist height. A properly balanced door should stay in place. If it falls or rises, the springs need adjustment. An unbalanced door strains the opener motor, especially problematic in hot weather.
Replace cracked, brittle, or flattened weatherstripping before summer. Good seals keep hot air out and cooled air in, reducing energy costs if your garage is climate-controlled.
Remove dirt, spider webs, and debris from the tracks. Use a damp cloth rather than lubricant on track surfaces—lubricated tracks can cause the door to slip.
Provide Ventilation: If possible, open windows or vents when the door's closed to prevent heat buildup that stresses the opener.
Limit Peak-Hour Use: The hottest part of the day puts the most strain on your system. When possible, operate the door during cooler morning or evening hours.
Keep the Door Closed: It might seem counterintuitive, but keeping the garage door closed during the hottest hours often keeps the garage cooler than leaving it open, especially if the door is insulated.
Monitor Opener Performance: If you notice the door moving more slowly or the opener running loudly, give the system a 15-minute break between uses.
Watch for these warning signs: - Door moving slower than usual - Unusual grinding or straining noises - Opener shutting off mid-cycle - Door sticking at certain points - Increased opener vibration
Consider scheduling a professional tune-up before summer arrives. Our technicians will: - Adjust spring tension for seasonal changes - Apply heat-resistant lubricants - Check opener motor condition - Inspect safety systems - Identify potential problems before they cause breakdowns
A little preparation now prevents emergency calls during the hottest days of summer.
