Garage Door Opener Not Working
in Arlington, TX
When your opener quits, it's not always the motor. The problem could be the remote, the wall button, the safety sensors near the floor, or the logic board inside the unit. Arlington's summer heat, regularly above 100 degrees in July and August, shortens the life of circuit boards and capacitors inside openers. Leaving a dead opener alone means you're stuck using the manual release every day, which gets old fast.
Quick Answer
Garage door openers stop working for a handful of reasons, from dead batteries to burned-out motors. Arlington's heat stresses the motor and circuit board harder than in cooler parts of the country. Sometimes the fix is a new battery or a sensor wipe. Other times the motor or board needs replacing. Call (817) 670-4611 so someone can figure out which one applies to your unit.
Telltale Signs
Warning Signs to Watch For
- The opener light comes on but the motor doesn't run
- The motor runs but the chain or belt doesn't move the door
- Neither the remote nor the wall button does anything
- The door reverses immediately after touching the ground
- The opener works sometimes but not others
- One sensor light on the floor bracket is blinking orange or red
Root Causes
What Causes Garage Door Opener Not Working?
Misaligned Safety Sensors
Two small sensors sit near the bottom of each track, about six inches off the floor. They send a beam across the opening. If the beam is broken or the sensors get bumped out of line, the opener won't close the door. Spiders love to nest in sensor brackets here in Arlington from April through October, and a web across the lens breaks the beam.
The Fix
Sensor Realignment and Cleaning
The technician realigns both sensors until the indicator lights show solid green, then cleans the lenses. If a sensor is cracked or corroded, it gets replaced.
Failed Logic Board
The logic board is the small circuit board that controls everything the opener does. Arlington's heat cycles, hot summers and cold fronts that drop below freezing in January, expand and contract solder joints until they crack. A failed board means the opener is completely dead or behaves erratically.
The Fix
Logic Board Replacement
The old board comes out and a compatible replacement goes in. On openers older than 12 to 15 years, it often makes more sense to replace the whole unit than to source a board for a discontinued model.
Worn Drive Mechanism
Chain drives stretch and belt drives crack after years of use. When the drive is too loose or broken, the motor spins but nothing moves the door. This is common on openers installed in the late 1990s and early 2000s in subdivisions in north Arlington near Randol Mill Road.
The Fix
Drive Chain or Belt Replacement
The technician replaces the chain or belt and adjusts the tension to the manufacturer's spec. A new drive on an otherwise functional motor gives the unit several more years of reliable use.
