South Pasadena’s August heat puts extra stress on garage doors. Before the next heatwave hits, run this quick checklist to spot common summer failures and book a free estimate before parts backorder season hits.
Check the tracks and rollers for summer wear
South Pasadena’s summer heat expands metal tracks and dries out rollers, causing misalignment and noisy operation. Run a straightedge along the tracks—if you see gaps wider than 1/8 inch, the tracks need adjustment. Check rollers for cracks or flat spots; if they’re brittle or flattened, they’ll jam in the heat. Don’t ignore squeaks—rollers should roll smoothly without lubrication in summer. If yours sound like a coffee grinder, schedule a Garage Door Repair South Pasadena before the next heat spike. We serve Altadena, Pasadena, and all nearby cities—no drive-time surprises.
Test the auto-reverse and safety sensors
My garage door reverses on my car’s roof rack every time I leave for work—why does this happen? It’s a classic summer sensor failure. Dust from South Pasadena’s dry Santa Ana winds coats the sensors, tricking the door into thinking there’s an obstruction. Wipe the lenses with a microfiber cloth and realign them so the indicator lights stay solid. If the door still won’t close or reverses randomly, the sensors may need replacement. Don’t wait for a stuck door in 100°F heat. Call us for a free safety inspection—we’ll calibrate or replace sensors same-day.
