CRITICAL SAFETY WARNING
⚠️ SAFETY NOTICE
Maintenance is safe when done correctly:
• Never adjust spring tension (requires specialized tools)
• Never remove cables under tension
• Always disconnect opener before manual testing
• Wear safety glasses when working overhead
This guide covers safe maintenance only. Spring adjustment, cable replacement, and major repairs require professional service.
Call 541-203-7676 if you discover worn parts during inspection.
Your garage door cycles 1,500+ times per year. Without maintenance, parts wear out 2-3x faster.
After servicing 3,000+ doors in Central Oregon, I can tell you this: The $20 and 30 minutes you spend on quarterly maintenance saves you $500-1,000 in premature repairs.
This guide shows you the exact maintenance routine we use professionally. Follow this schedule and your door will last 20+ years instead of 10-12. Bend's extreme climate (110°F summers, -10°F winters) makes this even more critical.
You'll learn what to lubricate, what to tighten, what to inspect, and what to never touch. Total time: 30 minutes, four times per year.

1
Visual Inspection - Check for Wear
Start with a complete visual inspection. Look for:
<strong>Springs</strong>: Check for rust, gaps, or deformation. Healthy springs are uniform in color and spacing. Rust = needs lubrication. Gaps = broken (call us immediately).
<strong>Cables</strong>: Look for fraying, especially where cables attach to bottom brackets. Frayed cables can snap - professional replacement needed.
<strong>Rollers</strong>: Steel rollers should spin freely. Nylon rollers shouldn't have cracks or chunks missing. Wobbling rollers need replacement.
<strong>Hinges</strong>: Check for cracks or excessive wear at pivot points. Loose hinge bolts cause door misalignment.
<strong>Weather stripping</strong>: Bottom seal should be flexible, not cracked. Damaged seals let in Bend's winter cold and summer heat.
<strong>Door panels</strong>: Look for dents, cracks, or warping. Bent panels affect balance and can bind in tracks.
Pro Tip: Do inspections in good lighting. Use a flashlight to check inside track channels and cable drums. Bend garages are often dim - you'll miss problems without proper light.

Lubricate All Moving Parts
Proper lubrication extends part life 30-50%. Use white lithium grease spray - it handles Bend's temperature extremes better than oil.
<strong>Springs</strong>: Spray the full length of torsion springs (the horizontal springs above the door). Apply liberally - springs should glisten. Wipe excess that drips.
<strong>Rollers</strong>: Spray the bearing where the roller meets the stem. Don't spray nylon roller wheels - only the metal bearing.
<strong>Hinges</strong>: One spray at each hinge pivot point. There are typically 8-12 hinges on a standard door.
<strong>Track</strong>: Light spray along the inside curve where rollers contact. Don't over-lubricate - excess attracts dirt.
<strong>Opener chain/belt</strong>: Chain drives get light spray. Belt drives get silicone spray ONLY (white lithium damages belts).
<strong>Lock mechanism</strong>: If you have a manual lock, spray the cylinder and latches.
Frequency: Every 3 months. Mark your calendar - January, April, July, October.
Pro Tip: In Bend, lubricate in fall (October) and spring (April) at minimum. Temperature cycling causes lubricant to degrade faster. Winter lubrication prevents ice buildup in track.
3
Test Door Balance
Proper balance reduces strain on the opener motor and extends spring life.
Disconnect the opener (pull red release cord). Manually lift the door to chest height (about 4 feet). Let go.
<strong>Perfect balance</strong>: Door stays in place.
<strong>Good balance</strong>: Door drifts slowly up or down (within 12 inches).
<strong>Poor balance</strong>: Door drops rapidly or shoots up.
If balance is off, springs need professional adjustment. Don't attempt this yourself - requires winding bars and specific torque.
Reconnect opener after test (push trolley toward motor until it clicks).
Safety: Never force a door that won't stay balanced. Heavy drop means spring tension is critically low - door could fall and cause injury. Call us immediately.
4
Tighten All Hardware
Vibration loosens bolts over time. Tighten (don't over-tighten):
<strong>Track brackets</strong>: Where tracks mount to wall/ceiling. Loose tracks cause binding.
<strong>Roller stems</strong>: The bolts holding rollers to door. Finger-tight plus 1/4 turn.
<strong>Hinge bolts</strong>: At each hinge. Check both sides of each hinge.
<strong>Opener mounting brackets</strong>: Where opener hangs from ceiling.
<strong>Header bracket</strong>: The bracket above the door that supports the rail.
Use a socket wrench. Snug but not torqued - you're preventing loosening, not crushing threads.
In Bend, temperature expansion/contraction loosens hardware faster. Quarterly tightening prevents cumulative loosening.
Pro Tip: Bring a bucket up the ladder with all your tools. Saves 10 trips up and down. Efficiency matters when you're doing this quarterly.
5
Check and Adjust Track Alignment
Misaligned tracks cause premature roller wear and noisy operation.
Use a 4-foot level against each vertical track section. Track should be perfectly plumb (straight up and down).
Check horizontal sections too - they should be level or have a very slight downward slope toward the back.
If tracks are off by more than 1/4 inch, loosen mounting brackets, adjust to plumb/level, and retighten.
Gaps between rollers and track: Should be 1/4 inch or less. Larger gaps mean tracks are too wide - tighten mounting bolts.
Bent tracks need professional replacement. Don't try to straighten them - you'll make it worse.
Safety: Never adjust tracks with the door closed and spring tension engaged. Always disconnect opener and secure door in open position first.

Test Safety Features
Modern openers have two federally-required safety systems. Test both:
<strong>Photo-eye sensors</strong>: Place an object (like a 2x4) in the door path. Close the door with the remote. It should reverse immediately when the beam breaks. If not, sensors are misaligned or dirty.
Clean sensor lenses with soft cloth. Align sensors so indicator lights are solid (not blinking). They must face each other perfectly.
<strong>Auto-reverse force</strong>: Hold the bottom of the door while closing. When you apply upward pressure (about 20 pounds), it should reverse. If it doesn't stop, force setting is too high - adjust on the opener motor.
<strong>Manual release</strong>: Pull red emergency cord. Trolley should disconnect. Test that you can manually lift the door. This is critical for power outages.
In Bend, winter condensation can fog sensor lenses. Keep them clean and dry.
Pro Tip: Test these monthly, not quarterly. Safety sensors save lives. We've prevented dozens of injuries from properly functioning sensors catching kids, pets, and cars.

Clean Tracks and Weather Stripping
Debris in tracks causes binding and roller damage.
<strong>Tracks</strong>: Wipe inside channels with a dry rag. Remove dirt, leaves, dead insects. Don't use solvents - they remove protective coatings.
<strong>Weather stripping</strong>: Clean the bottom seal with mild soap and water. Remove dirt and leaves that prevent proper sealing.
Check for damage: Cracked weather stripping needs replacement. Torn seals let in moisture, rodents, and temperature extremes.
Bend-specific: Check for pine needles and juniper debris. Our local trees drop debris year-round. Spring and fall cleanings are essential.
<strong>Optional</strong>: Repaint door if finish is fading. Bend's intense summer sun degrades paint. Repainting every 5-7 years protects wood and steel doors from moisture.
Pro Tip: Replace weather stripping in spring (April/May). New rubber is more flexible in warm weather - easier installation. Old brittle stripping installed in winter cracks immediately.
Frequently Asked Questions
How often should I do this maintenance?
Quarterly (every 3 months) for full routine. Monthly for safety sensor tests and visual inspection. In Bend's climate, quarterly is minimum - temperature extremes accelerate wear. We see 30% longer part life in homes that follow quarterly schedules.
What type of lubricant should I use?
White lithium grease spray for everything except belt-drive openers (use silicone spray on belts). Don't use WD-40 - it's a cleaner, not a lubricant. Don't use motor oil - it drips and attracts dirt. Lithium grease stays put in Bend's temperature swings.
Can I do this maintenance if I have a broken spring?
No. Replace the spring first. Maintenance assumes a functioning door. Broken springs make the door unsafe to operate or inspect. Call 541-203-7676 for spring replacement, then resume normal maintenance schedule.
Should I lubricate extension springs too?
Yes, but they're less critical than torsion springs. Extension springs (side-mount springs) benefit from lubrication but don't require it as often. Spray them during quarterly maintenance. Focus more on torsion springs - they work harder.
What if I find cracked rollers during inspection?
Replace them immediately. Cracked nylon rollers can shatter and jam in tracks. Steel rollers with worn bearings cause loud operation and track damage. We charge $120 to replace all rollers (12-14 rollers typically). DIY cost: $20-40 for roller set.
Do I need professional maintenance if I do this quarterly?
Recommended every 2-3 years. We catch things DIY maintenance misses: cable wear patterns, spring life estimation, motor brush wear, track wear measurements. Our tune-up ($99) includes parts we can assess with specialized tools. Most DIY maintainers call us every 2 years for professional check.
You now have the complete maintenance routine that extends garage door life from 10-12 years to 20+ years.
Set calendar reminders for January, April, July, and October. Each session takes 30 minutes. Total annual time investment: 2 hours. Money saved: $500-1,000 in avoided repairs.
Bend's climate is particularly hard on garage doors. Temperature cycling, moisture, and UV exposure accelerate wear. Quarterly maintenance offsets these stresses.
Can't commit to quarterly maintenance? We offer annual tune-up plans: $99/year includes:
• Professional inspection and adjustment
• Complete lubrication
• Safety system verification
• Hardware tightening
