Garage Door Opener Not Working
in Carrollton, TX
A garage door opener that does not work is frustrating, but the fix depends on what actually failed. Carrollton sees strong thunderstorms from spring through early fall, and power surges during those storms damage opener electronics more often than most homeowners realize. Ignoring it usually means the opener gets worse, not better.
Quick Answer
A garage door opener stops working because of a dead remote battery, a tripped circuit, a failed logic board, or a broken drive gear. Carrollton power surges during summer storms are a common reason logic boards fry. A technician tests each part to find the actual failure before replacing anything. If the door is stuck closed, call the same day.

Root Causes
What Causes Garage Door Opener Not Working?
Power Surge Damage
Summer thunderstorms in Carrollton regularly send voltage spikes through home electrical systems. Those spikes can burn out the logic board inside the opener unit. A fried logic board shows up as the opener doing nothing, or doing something random, even when the power is on.
The Fix
Logic Board Replacement
The old logic board is pulled out and replaced with a new one matched to the opener model. A surge protector installed on the outlet prevents the same thing from happening again.
Failed Drive Gear or Belt
The drive gear is the small plastic gear that transfers motor power to the belt or chain. It wears out after years of use, and Carrollton heat makes plastic components brittle faster. When the gear strips, the motor runs but nothing moves.
The Fix
Drive Gear or Belt Replacement
A technician opens the opener housing, removes the worn gear, and installs a new one. If the belt or chain is also cracked or stretched, it gets replaced at the same time.
Misaligned Safety Sensors
Garage door openers have two small sensors near the floor on each side of the door. If something bumps them out of alignment, the opener will not close the door. Kids, lawn equipment, and even the heavy clay soil shifting slightly under the garage slab can move sensor brackets over time.
The Fix
Sensor Realignment
The sensors are repositioned so both lenses face each other directly, then locked in place. The technician confirms the indicator lights are solid before testing the door.
