When a door refuses to close, blinks at you and goes straight back up, the fault is usually in the controls rather than the door. Tempe Garage Door Service traces the safety sensors, wall button, keypad and remotes as one system and tells you which part is actually at fault before anything is replaced.
Control faults are common in Tempe garages because the equipment lives in the heat. Sensor brackets sit inches above the floor where a bike wheel, a recycling bin or a ridge of blown dust can break the beam, and the thin low-voltage wire running to them gets brittle after years of summer temperatures.
The work starts with finding out whether the opener is refusing to close or being told to stop. Those look identical from the driveway and lead to completely different repairs.
Both photo-eye units are checked for alignment, height, loose brackets and sun glare falling directly on the receiving eye. The beam is tested through a full close, and the door is confirmed to reverse when the beam is broken, which is the point of having them.
Sensor wire runs along the wall where it gets nicked by ladders, shelving and nesting pests, and staples driven too tight cut through the insulation. The run is inspected end to end, along with the wall button, its terminals and the connections at the opener head.
Exterior keypads take the worst of the sun and their buttons and seals give out. Remotes, keypads and any built-in car buttons are tested, reprogrammed to the opener where that is the fix, and replaced only when the unit itself has failed.
Most control faults are small. An alignment, a new length of low-voltage wire, a replacement wall button or a keypad swap all take one visit, and you hear which of those it is before the work is agreed. Safety sensors are never simply bypassed to make a door close, because a door that cannot detect an obstruction is a hazard to children, pets and vehicles.
Some symptoms only look like control faults. A motor that hums without moving the door, or a door that reverses because it is binding in the track, needs opener repair or attention to the hardware instead. Where the door itself is stiff or out of balance, a maintenance tune-up often clears the fault for good.
Before you call, the opener troubleshooting guide walks through the checks that are safe to do yourself, and the repair versus replacement comparison covers what to do when an opener is old enough that parts are getting hard to find. The rest of the work is listed on the services page, coverage for outlying communities such as Apache Junction has its own page, and details can be sent from the request page.
Look at the two small units at the bottom of the door tracks. Clear anything in front of them, wipe the lenses, and check that both indicator lights are steady. A ridge of dust along the floor is enough to break the beam. If the lights stay off or keep blinking after that, the alignment, the wiring or the units themselves need checking.
The units are fairly robust, but their wiring and mounting are not. Summer temperatures in a closed garage make the thin sensor wire brittle and the plastic brackets sag, which slowly drops one eye out of line. Low afternoon sun shining straight into the receiving eye can also stop a door closing at the same time every day.
Usually because the keypad lost its code when the power went and needs reprogramming to the opener, which takes a minute at the motor head. If a fresh battery makes no difference at all, heat and sun have often gotten into the keypad’s seal and corroded the contacts, and the unit is replaced rather than repaired.
No. Bypassing them removes the only thing that stops a closing door on an obstruction, and openers are built to require them for that reason. If a sensor fault is keeping the door open, keep the door shut using the wall button while standing where you can see the opening, and have the fault fixed properly.
Tell us what the lights on the sensors and the opener are doing, and the visit can be planned around it.
