Most people install an electric rolling door and forget about it until something breaks. That's expensive. A little maintenance goes a long way. Here's what you should be doing.
Monthly Checks
Run the door up and down. Listen. Any new noises? Grinding, squeaking, clicking? Investigate.
Check the track. Is it clean? Debris in the track is the most common cause of rough operation. Sweep or vacuum the track. A can of compressed air is good for getting grit out of corners.
Check the remote batteries. If the range is getting shorter, change the batteries before they die completely. Remotes always fail at the most inconvenient time.
Test the manual operation. Pull the chain or use the crank to open and close the door. It should move with reasonable effort. If it's very hard to move, the spring tension or balance is off, and the motor is working too hard.
Quarterly Maintenance
Lubricate moving parts. The rollers or sliders in the track. The chain between the motor and shaft. The hinge points. Use a silicone spray or white lithium grease. Wipe off excess.
Check all bolts and screws. Vibration loosens hardware over time. Tighten the guide rail mounting bolts, motor mount bolts, and limit switch bracket screws.
Clean the photo-eye sensors if the door has them. Dust and spider webs can block the beam.
Inspect the curtain or slats. Look for dents, bends, or loose slats. A bent slat will catch in the track. A loose slat can jam the door completely.
Annual Service
Have a technician inspect the motor. Check the capacitor, wiring connections, and brake function.
Check the spring tension. Springs lose tension over time. A door with weak springs is heavy to lift and wears out the motor faster.
Test the auto-reverse safety feature if the door has one. Place a solid object in the door's path. The door should reverse on contact. If it doesn't, adjust or repair immediately.
For fire shutters, do a full fire test. Simulate an alarm and confirm the door descends correctly. Test the battery backup. Test the fusible link.
What Not to Do
Don't pressure-wash the door. Water gets into bearings and electrical components. Don't use petroleum-based lubricants on rubber seals. They degrade the rubber.
A maintained door lasts twice as long and costs half as much in repairs over its life. Thirty minutes a month is a good investment.
