Preventative maintenance is a vital step in assuring your commercial doors are safe and last for as long as possible. We recommend following a checklist. We also advise having your doors evaluated at least one time per year by a trained and certified technician.
Below are some maintenance specifics for rolling doors.
Recommended Preventative Maintenance Schedule for Rolling/Coiling Steel Doors
Preventative maintenance on rolling/coiling steel doors varies depending upon the operating conditions. How often it should be maintained depends upon the following:
- Is the door in a corrosive environment?
- Is the door located by saltwater?
- Is the door in a wash down room?
- Is there a lot of dust getting into and on the door?
- Is the door the primary entry and exit into the building?
- Is the door part of the loading dock area and exposed to high forklift traffic and potential damage?
- Is the door the primary entry and exit into the service area and being used for vehicles and pedestrians?
- Visually look at how the door sits in the opening. Can you see light coming under one side more than the other?
- Look at the door curtain. Can you see daylight between the slats and the vertical guides?
- Watch the door as it opens and closes.
- Is it binding in the tracks?
- Does the motor run awhile before the door moves?
- Does the door bag up when it hits the floor? Does it slam into the door stops when it reaches the header?
- Look at the vertical guides that the door travels in.
- Are they hit or damaged?
- Are there missing bolts?
- Is the bottom weather seal intact and making proper contact with the floor?
- Is the side weather seal intact and making contact with the curtain?
- Can you see metal shavings at the base of the guides?
- Do you hear any clunking sounds from the gears or inside the coil as the door opens and closes?
- Is the hood damaged and dented?
- Are the door stops properly hitting the bottom bar or does the door travel past?
If the door is motor operated:
- Check the open, stop, and close button to make sure all are working.
- Check the reverse edge on the bottom of the door to make sure the door reverses when it is closing.
- Check the photo eyes to make sure the door reverses when closing.
- If a loupe is cut into the ground surface, check to make sure it’s opening the door when a vehicle is positioned over it.
- Check the timer to insure proper open or close time after vehicle leaves.
- If you answered yes to any of the above issues, your door should be checked by a trained door technician immediately.
- If any of the safety equipment is not working, your door should be taken out of service until the problem is resolved.
- Yearly or semi-annual preventive maintenance should only be performed by trained door technicians.
- Excessive grease and lubrication will actually hamper the door function unless properly applied to where it needs to be.
- Do not continue to operate a door that has been damaged.
- Do not continue to operate a door that is difficult to completely open or close.
- Do not use an electric operator to “power open or close” a poorly operating or damaged door.
- Do not attempt to wind, or unwind, or otherwise tamper with a spring counterbalance system.
- Only qualified persons should ever attempt adjustment of the counterbalance spring assembly on any door.
- Only qualified door technicians should ever work on the motor operators or safety equipment attached.
