Garage Door Opener Not Working
in Fort Myers, FL
Fort Myers gets more lightning strikes per square mile than most of the country, and that means garage door openers here take a beating from power spikes. Openers in homes built before 2000 in neighborhoods like Gateway and Estero are often still running on units that are 20 or more years old. When an opener fails, people often assume it's the remote battery, but most of the time the problem is inside the unit or in the door mechanics the opener is fighting against.
Quick Answer
A garage door opener that stops working is usually caused by a dead circuit board, a failed capacitor, or a motor burned out from overwork. Fort Myers power surges during afternoon thunderstorms fry opener circuit boards more often than people expect. A technician diagnoses which part failed and replaces it or the whole unit if it's past its useful life. If the opener hums but the door doesn't move, stop pressing the button — you're burning out the motor.
Telltale Signs
Warning Signs to Watch For
- Pressing the remote or wall button does nothing at all
- The opener motor hums for a few seconds but the door doesn't move
- The opener light comes on but the motor won't run
- The door reverses immediately after touching the floor
- The remote only works when you stand within a few feet of the unit
- The opener runs but the trolley doesn't pull the door
Root Causes
What Causes Garage Door Opener Not Working?
Power Surge Damage to Circuit Board
Fort Myers sees afternoon thunderstorms nearly every day from June through September. A nearby lightning strike or a utility surge can fry the logic board inside the opener unit even if you have a surge protector on the outlet. The board controls everything, so when it goes, the whole unit goes dead.
The Fix
Circuit Board Replacement or Opener Replacement
A technician tests the board with a meter to confirm it's the problem, then replaces the board if a replacement part is available for that model. On older openers, a new unit is often more practical than hunting down a discontinued board.
Motor Burnout from Overload
If a spring is broken or the door is off track, the opener motor strains hard on every use. Fort Myers homes used as short-term rentals sometimes see the garage door used 20 or more times a day, which is far above what most residential motors are rated for. The motor overheats and fails.
The Fix
Motor Replacement with Load Check
The technician replaces the motor and checks that the door itself moves freely before reconnecting. If the door is too heavy or has a mechanical problem, fixing only the motor means the new one burns out too.
