When your garage door refuses to close, it's more than just an inconvenience—it's a security concern and potentially a sign of underlying problems that need attention. North Carolina homeowners face this frustrating situation more often than you might think, especially with our region's unique weather patterns that can affect garage door systems.
At E-Z Up Door Company, we've helped countless homeowners across Ashe, Watauga, Wilkes, and surrounding counties diagnose and resolve garage door closing issues. In this comprehensive guide, we'll explore the seven most common reasons your garage door won't close in North Carolina and provide practical solutions to help you address these problems effectively.
Safety First: Before You Troubleshoot
Before attempting any garage door troubleshooting, always prioritize safety:
- Disconnect the garage door opener by pulling the emergency release cord (typically a red handle hanging from the opener track)
- Keep children and pets away from the garage door during inspection
- Wear protective gloves when examining mechanical components
- Never adjust or repair tension springs yourself—these are under extreme pressure and require professional handling
Common Cause #1: Photo Eye Sensor Misalignment
The Problem: Modern garage doors include safety sensors (photo eyes) mounted near the floor on both sides of the door. These small devices create an invisible beam across the door opening. If anything breaks this beam while the door is closing, the door will automatically reverse to prevent accidents.
Why It Happens in NC: North Carolina's high humidity, especially during summer months, can cause condensation on sensor lenses. Additionally, our seasonal storms and wind can gradually shift sensor positioning.
Signs to Look For:
- Garage door closes partially then reverses
- Opener lights blink when you try to close the door
- One or both sensor lights are dim or unlit
DIY Solution:
- Check that nothing is blocking the sensor beam
- Clean both sensor lenses with a soft, lint-free cloth
- Make sure both sensors are securely mounted at the same height (typically 4-6 inches above the floor)
- Verify the sensors are properly aligned—when aligned correctly, both sensors should have a steady light (often green on the receiving sensor and red on the sending sensor)
Common Cause #2: Track Obstruction or Damage
The Problem: Garage doors operate on metal tracks that guide the door as it opens and closes. Any obstruction or damage to these tracks can prevent proper door movement.
Why It Happens in NC: North Carolina's varying temperatures cause metal contraction and expansion, potentially warping tracks over time. Additionally, falling tree debris, particularly during our autumn and storm seasons, can create obstructions.
Signs to Look For:
- Door stops at the same spot each time
- Scraping or grinding noises during operation
- Visibly bent or damaged tracks
- Door appears misaligned or crooked when partially open
DIY Solution:
- Inspect the entire track length for obvious obstructions (leaves, small branches, tools, toys)
- Remove any debris carefully
- Check for dents or damage in the track
- Tighten any loose bolts securing the track to the wall (but do not attempt to bend or reshape damaged tracks yourself)
Common Cause #3: Broken Springs or Cables
The Problem: Garage door springs and cables counterbalance the door's weight, making it possible for the opener to lift and lower it easily. When these components fail, the door may become too heavy for the opener to operate safely.
Why It Happens in NC: North Carolina's temperature fluctuations and humidity create additional wear on these components. Springs typically have a lifespan of 7-10 years with normal use, but our climate can accelerate wear.
Signs to Look For:
- Door is extremely heavy to lift manually
- Loud snapping sound occurred before the problem started
- Visibly broken or unwound spring above the closed door
- Loose cables hanging alongside the door
- Door appears crooked or slanted when partially open
Solution: This requires professional repair. Do not attempt to adjust or replace springs or cables yourself. These components store enormous tension and can cause serious injury if mishandled. Contact our service team for prompt, professional assistance.
Common Cause #4: Remote Control/Wall Switch Issues
The Problem: Sometimes what appears to be a door closing problem is actually an issue with the controls that operate the door.
Why It Happens in NC: Battery deterioration accelerates in humid conditions, which are common in North Carolina. Additionally, electrical components can be affected by our frequent summer thunderstorms.
Signs to Look For:
- Door operates from the wall switch but not the remote (or vice versa)
- Multiple remotes are not working
- Wall switch light is dim or unresponsive
- Remote indicator light is weak or doesn't illuminate
DIY Solution:
- Replace the batteries in your remote control
- Check that wall switch connections are secure
- Reprogram your remote following the manufacturer's instructions
- Test the door operation limit settings on the opener unit
- If you recently experienced a power surge from a thunderstorm, you might need to reset your opener
Common Cause #5: Limit Switch Problems
The Problem: Garage door openers have limit switches that tell the motor when to stop running because the door has reached its fully closed (or open) position. When these settings are incorrect, the door may reverse before closing completely.
Why It Happens in NC: Seasonal changes in North Carolina can affect the operation of garage door components. As temperatures rise in summer, the metal in your garage door system expands slightly; conversely, it contracts during winter months. These subtle changes can throw off previously accurate limit settings.
Signs to Look For:
- Door reverses before touching the floor
- Door closes completely but then immediately reverses
- Opener runs longer than it should after the door is fully closed
- Door doesn't close completely, leaving a small gap
DIY Solution:
- Locate the limit switch adjustment screws on your opener unit (consult your owner's manual for the exact location)
- Make small, incremental adjustments following the manufacturer's directions
- Test the door operation between adjustments
- If you're uncomfortable making these adjustments, contact our professional technicians for help
Common Cause #6: Motor or Gear Issues
The Problem: The opener's motor or internal gears can wear out over time, causing operational problems including the inability to close properly.
Why It Happens in NC: North Carolina's high summer humidity can cause premature wear on motor components, while seasonal temperature fluctuations can affect lubricant effectiveness on gears.
Signs to Look For:
- Motor runs but the door doesn't move (or moves very slowly)
- Unusual grinding noises from the opener unit
- Motor hums briefly but then shuts off without moving the door
- Motor runs longer than normal to close the door
Solution: This typically requires professional diagnosis and repair. Modern garage door openers are complex devices with many specialized parts. Our experienced technicians can quickly diagnose motor and gear problems and recommend the most cost-effective solution.
Common Cause #7: Weather-Related Problems in North Carolina
The Problem: North Carolina's distinctive weather patterns create unique challenges for garage door systems.
Why It Happens:
- Summer heat and humidity can cause wood doors to swell
- Sudden temperature changes can affect metal components
- Heavy rain can create water intrusion issues
- Strong winds from coastal storms can put pressure on doors
- Seasonal debris (leaves, pine needles, pollen) can accumulate in tracks
Signs to Look For:
- Door operation changes with weather conditions
- Door sticks during particularly humid periods
- Components show rust or corrosion
- Track contains seasonal debris
- Weather seals appear damaged or compressed
DIY Solution:
- Keep tracks clean and free of debris
- Regularly clean and lubricate moving parts (using proper garage door lubricant, not WD-40)
- Inspect and replace damaged weather seals
- Consider a dehumidifier in your garage during the most humid months
- Schedule seasonal maintenance checks to address weather-related issues proactively

Frequently Asked Questions
How do I manually close my garage door if the opener isn't working?
First, disconnect the opener by pulling the emergency release cord. Then, carefully lower the door to the closed position. Most doors will stay closed when fully lowered, but for added security, you can lock the door using the manual slide lock located on the inside of the door.
Can humidity really affect my garage door that much in North Carolina?
Yes. North Carolina's high humidity levels, particularly in summer months, can affect multiple components of your garage door system. Wood doors can absorb moisture and become heavier or slightly warped, metal components can develop corrosion more quickly, and electrical components can be affected by moisture.
How much does it typically cost to repair a garage door that won't close in North Carolina?
Repair costs vary widely depending on the cause. Simple fixes like sensor realignment might cost $75-150, while more complex repairs involving springs or opener replacement can range from $150-600. At E-Z Up Door Company, we provide transparent pricing and will always explain your options before proceeding with any repair.
Is it normal for my garage door to operate differently in summer versus winter?
Yes, seasonal changes can affect garage door operation. Metal expands in heat and contracts in cold, which can subtly impact how your door moves on its tracks. Additionally, lubricants may become less effective in extreme temperatures. Regular seasonal maintenance helps address these natural fluctuations.
How long should my garage door opener last in North Carolina conditions?
With proper maintenance, most quality garage door openers will last 10-15 years in North Carolina conditions. However, factors like humidity, usage frequency, and power surge exposure can affect lifespan. Regular maintenance can significantly extend the life of your opener.
Can I use WD-40 to lubricate my garage door?
No. While WD-40 is a great product for many applications, it's not ideal for garage doors. WD-40 is primarily a solvent, not a lubricant, and can actually wash away the necessary grease on certain components. Instead, use a silicone-based or lithium-based lubricant specifically designed for garage doors.
