Should be replaced immediately. Please do not attempt to open or close your door with a frayed or broken cable as this may cause the door to come away from the tracks. Garage doors can weigh over 200 lbs and may cause severe damage if they fall.
Are problems that need to be repaired before they cause more damage. Broken hinges can put undue pressure on the door joints causing the sections to bend or crimp. Worn out rollers can come out of the track, or make your door run bumpy and loud. Replacing these items ensures your door is running smoothly and safely while avoiding larger problems in the future.
