Regularly check the tracks on either side of the door to be clean and free of debris and dust. Accumulation of debris obstructs wheel movement. Check for rust and use a step ladder to see all parts of the track and roller. Check for verticality of the roller track with a plumb line. Replace rollers within 5 – 7 years. Inspect twice or thrice annually to replace cracked, chipped, and worn rollers.
Remove the rollers by detaching from the brackets that hold them to the door, and never remove the bottom roller bracket because it connects to the lift cables and is under tension. For extreme roller and track cases, call professionals like us who either repair or replace them to ensure your door functions as required.
