  • Lubricate hinges, rollers, and operator rail annually
  • Replace visibly damaged rollers
  • Reprogram remotes/keypads if unresponsive
  • Identify and repair sticking points on jammed doors

Safety Sensor Issues

One of the most common issues that crop up with garage door openers is problems with the safety sensors. These sensors prevent the garage door from closing when there is an obstruction in its path. If the sensors are misaligned or dirty, it can cause a range of issues.

Causes

  • Door refuses to close
  • Door closes then immediately reopens
  • Door opens and closes erratically

How to troubleshoot and fix

  • Inspect sensors and ensure they are pointed directly at each other
  • Make sure nothing is obstructing the path between the sensors
  • Clean any dirt, debris, or moisture from the sensors
  • Check for damage to the wiring or alignments
  • Refer to manufacturer guidelines for help with realignment

Getting the safety sensors realigned properly is crucial because they prevent serious injury or property damage. Spending a few minutes on sensor maintenance can save time, money, and headaches down the road.

Blocked Safety Sensor Signals

If the safety sensors have proper alignment yet your garage door still refuses to operate smoothly, there may be some type of obstruction causing interference.

Causes

  • Inability to open or close door
  • Erratic opening and closing behavior
  • Flashing sensor lights with no obstruction

How to troubleshoot and fix

  • Inspect the external area around your garage door and look for any objects that could be interrupting the sensor’s signal path. Watch out for branches, bushes, cobwebs, etc.
  • Check the interior path of the sensor beam inside your garage for obstacles like storage items, vehicles in the path, hanging objects, etc.
  • Remove any obstructions that could be interfering with continuous sensor signals
  • Test and observe door function once potential blockages are cleared

Keeping the path clear between your garage door’s safety beam sensors is vital for normal operation. Perform routine inspections and upkeep as preventative maintenance.

Lack of Adequate Lubrication

Another extremely common issue for garage doors is failing to properly lubricate all of the moving components. Parts like hinges, rollers, and metal operator rails all need occasional lubrication to avoid seizing up or grinding.

Causes

  • Squeaking, grinding noise when opening or closing
  • Resistance or difficulty moving door
  • Intermittent stopping or starting

How to troubleshoot and fix

  • Inspect door hinges and rollers for signs of rust or stiffness
  • Test door manually for areas of friction resistance
  • Clean and lubricate hinges, rollers, and operator rails
  • Use spray lubricants or lithium grease
  • Focus lubrication on roller shaft, bearings, and hinges
  • Consult owner’s manual for brand lubrication specs

Taking the time to regularly grease your garage door’s moving metal parts can help it run quietly, smoothly, and reliably for years before needing service.

Damaged or Worn Rollers

The small wheels that your garage door moves along called “rollers” often incur damage from years of metal-on-metal friction. If these become excessively worn or cracked, replacing them is required.

Causes

  • Grating, squealing noises
  • Tilting or visible misalignment
  • Intermittent sticking during operation

How to troubleshoot and fix

  • Manually operate the door and inspect each roller closely
  • Check for flat spots, chipping, cracking, or missing chunks
  • Replace any severely damaged rollers
  • Ensure roller spins freely without friction or resistance
  • Match new replacements to the original roller size

Allowing damaged rollers to continue deteriorating can damage other (more expensive) components of your garage door. Replacing bad rollers as-needed helps prevent bigger problems.

Remote Control and Keypad Reprogramming

Today’s garage door openers are integrated systems with features like remote operation. If the remote suddenly stops working to open or close your door, reprogramming is likely needed.

Causes

  • No functionality from handheld remote
  • Unresponsive or intermittent keypad operation
  • Usually from depleted battery or lost signal

How to troubleshoot and fix

  • Replace remote control battery if applicable
  • Re-sync remote with garage door opener motor head unit
  • Consult owner’s manual for proper pairing procedures
  • For keypads, check for low battery warnings
  • Reset wi-fi settings according to device instructions

With some installer remote controls, special tools are needed for rebooting connectivity. If you’re unable to re-establish the signal, a repair professional can help revive operation quickly.

Sticking or Jammed Garage Doors

Sometimes the rolling mechanism in a garage door opener will start to catch at certain points along the rails or ceilings. This causes sticking and resistance when trying to operate the door manually or with the motorized opener.

Causes

  • Difficulty opening or closing (requires extra force)
  • Intermittent mid-cycle stopping
  • Unusual or alarming sounds

How to troubleshoot and fix

  • Inspect tracks along the ceiling for debris or damage
  • Check for broken cables, springs, pulleys causing snags
  • Diagnose and lubricate sticky hinges or frozen rollers
  • Clear out obstructions like small pebbles or other debris
  • Straighten tracks and tighten any loose hardware
  • Repair/replace severely damaged components

If attempts to mitigate the sticking points prove unsuccessful, a garage door specialist can inspect and identify any underlying hardware issues that require replacement or repairs.

When to Call a Garage Door Professional?

Even if you exhaust all of the DIY troubleshooting methods above, sometimes contacting a trained garage door technician makes the most sense for completing the necessary repairs or parts replacements. Warning signs that professional expertise may be needed include:

  • Inability to reprogram electronics like remotes or keypads
  • Major component damage like torn cables or broken springs
  • Persistent sticking, jerking movement during operation
  • Tilted tracks, misaligned sensors, or other fundamental issues

Garage door contractors have specialized tools, parts on hand, and the know-how to efficiently handle major problems. Investing in proactive maintenance from a professional every couple years can also prevent larger failures and safety hazards.
