Garage Door Opener Repair in Sanger, TX
Every opener sold in the United States since 1993 is required to have an external reversal system, normally photo eyes mounted within six inches of the floor. If your unit predates that, or if the photo eyes have been bypassed by a previous repair, that is a safety problem rather than a convenience problem, and it is the first thing we address on a Sanger call.

The opener is the smallest force in the system
A half or three quarter horsepower opener produces enough force to move a door that the springs have already balanced. It is not a lifting device. When the counterbalance drifts out of range, the opener silently absorbs the difference on every cycle, and the components that fail are the ones in the force path: the plastic drive gear, the trolley, the opener arm, and the top section where the arm attaches. This is why the balance test comes before any opener diagnosis. Replacing an opener on an unbalanced door is a repair with a timer on it.
Reading the fault from the behavior
The motor runs and the door does not move: drive gear, broken chain or belt, or a disconnected trolley. The motor hums and does nothing: usually a failed capacitor or a seized motor. Nothing at all happens from the remote or the wall button: power, logic board, or in some cases the wall control wiring shorted by a staple. The door goes down and immediately reverses: photo eyes, close force, or close limit. The door opens partway and stops: open limit or an obstruction the force setting is detecting. The door closes but the light does not come on and the unit beeps: on newer units this is battery backup status rather than a fault at all.
Photo eyes are the fault we are called about most and the fastest to fix
Two sensors face each other across the opening within six inches of the floor. One transmits an infrared beam, the other receives it, and interrupting that beam reverses a closing door. They go wrong in ordinary ways: a bracket knocked by a bicycle, a lens filmed over with dust, a spider building across the aperture, a bump that leaves the sending unit pointing slightly off axis, and low winter sun coming through the open door and saturating the receiver. Most units indicate the state of the eyes with steady and blinking LEDs, and a blinking sensor LED means the pair is not seeing each other. Bypassing them, which some previous repairs have done with a jumper, defeats the only device that would stop the door on a child or a pet.

The visit
How a Sanger call runs
Door first, opener second
The trolley is released and the door lifted by hand to confirm the counterbalance is in range. If the door is heavy or drifts, that is corrected before any conclusion is drawn about the opener, because otherwise the diagnosis is unreliable.
Fault reproduction
We run the unit and watch the failure happen, noting where in travel it occurs, what the motor does, and what the indicator lights and sensor LEDs report. Intermittent faults get exercised rather than guessed at.
Component testing
Depending on the symptom this covers drive gear and chain or belt condition, capacitor, motor, logic board, limit switch positions, force settings, wall control wiring, and photo eye alignment and power.
Repair or replace, with the reasoning
You get the cost of the repair alongside the cost of replacement and the honest case for each, including the age of the unit and what else on it is likely to reach end of life soon.
Set travel, force, and safeties
Open and close limits are set to the door, force is set to the minimum that operates reliably, remotes and keypads are programmed, and both the photo eye reversal and the mechanical contact reversal are tested before we leave.

Questions
Garage Door Opener Repair in Sanger
My opener runs but the door does not move. What is that?
Most often a stripped drive gear, which is the nylon worm gear inside the motor head on a chain drive unit. It is a common wear item and a normal repair. It can also be a broken chain or belt, or a trolley that has been left disconnected after someone pulled the release handle. All three are repairable without replacing the opener.
The door closes and then immediately opens again. Why?
Three usual causes, in order of likelihood: photo eyes out of alignment or obstructed, a close limit set past the floor so the opener keeps pushing after the door has landed, or something adding resistance in the last foot of travel such as a hardened bottom seal or a binding roller. Check the sensor LEDs first, since that costs nothing.
How long should an opener last?
Ten to fifteen years is a fair expectation for a residential unit in normal use, with the drive gear and capacitor as the parts most likely to need attention before then. The variable that shortens it most is door balance, because an opener that has been fighting tired springs is doing far more work per cycle than the design intends.
Is a battery backup worth it?
If your garage is the primary entrance to the house or the only exit for a vehicle, yes. During an outage the alternative is releasing the trolley and lifting a door by hand, which is straightforward on a balanced door and difficult on a heavy one. Battery backup units also hold their programming and keep the safety sensors live through the outage.
Can I install a new opener myself?
It is a genuinely feasible DIY job on a door with a healthy counterbalance, and the instructions are decent. Two cautions. Confirm the door balances by hand before you start, because a new opener on an unbalanced door will fail early. And do not skip the photo eye installation or mount the sensors higher than six inches off the floor to make the wiring easier.
