Garage Door Opener Not Working
in Garland, TX
Garage door openers in Garland take a beating from heat. A unit stored in an uninsulated garage can see temperatures above 130 degrees on a July afternoon. Most openers are only rated to operate reliably up to about 110 degrees. Units installed in the early 2000s or before are well past their expected lifespan and prone to failing on the hottest days of the year.
Quick Answer
Opener failures in Garland are usually a dead remote battery, a tripped safety sensor, or a burned-out motor on a unit that is more than 15 years old. Check the sensors on each side of the door first, then try the wall button. If neither works, the motor unit may need to be replaced. Call for an inspection if the motor hums but the door does not move.
Telltale Signs
Warning Signs to Watch For
- The remote button does nothing at all
- The opener light blinks but the door does not move
- The motor hums for a few seconds and then stops
- The wall button works but the remote does not
- The door reverses immediately after it starts to close
Root Causes
What Causes Garage Door Opener Not Working?
Blocked or Misaligned Safety Sensors
Two small sensors sit about six inches off the floor on each side of the door. They send a beam across the opening, and if it is broken or one sensor is bumped out of alignment, the opener refuses to close the door. Garland's heavy summer storms blow debris into garages, and that debris often nudges a sensor just enough to break the beam.
The Fix
Sensor Realignment and Cleaning
The sensors are wiped clean of dust and spiderwebs, then repositioned so they point directly at each other. If the wiring is damaged or a sensor is cracked, the sensor unit is replaced.
Heat-Damaged Motor or Logic Board
An uninsulated Garland garage in July can reach over 130 degrees by mid-afternoon. The logic board inside the opener is a circuit board, and repeated exposure to that kind of heat degrades the solder connections and capacitors. Openers that are 15 or more years old rarely survive more than a few summers of that treatment.
The Fix
Opener Motor Unit Replacement
The full opener unit is replaced with a current model rated for the door's weight and size. Adding a garage door insulation kit or an attic vent helps slow down the heat damage on the replacement unit.
