Signs the sensors are the problem

  • The door goes down partway and reverses, or will not close at all.
  • The opener lights blink when you press the button, and the door does not move.
  • One sensor light is off, flickering or a different color from the other.
  • It works fine most of the day and fails at certain times.
  • You can press the wall button, hear the opener click, and nothing happens.

If the door will not close and the sensors are fine, see garage door will not close. If the door will not open either, go to why a garage door will not open, which covers the full set of checks.

The five minute fix

  1. Look at the two sensors near the floor, one on each side of the door. Remove anything in the way, such as a bag, a bike wheel or a stored box.
  2. Wipe both lenses with a dry, lint free cloth. Low sensors collect dust and cobwebs.
  3. Check that each sensor is pointing straight at the other. If one is bent, loosen its wing nut, turn it until the light glows steady, and tighten it.
  4. Gently tug the wires at the sensors and at the opener to make sure they are attached.
  5. Close the door with the remote and see if it makes it to the floor.

If the door still reverses, keep reading. If one light stays dark, the sensor or the wire behind it has probably failed.

Where the safety sensors sit at the garage door openingFront view of a garage door opening with two safety sensors mounted low on each side, a dashed beam between them, and a note that the manufacturers say to mount them no higher than six inches above the floor.6 in maxSensor eye (sends the beam)Sensor eye (receives it)Invisible beam: if anything breaks it, the door will not closeBoth eyes must face each other, level and clean
Illustration only: the sensor eyes sit low at each side of the opening and face each other across it. LiftMaster and Genie manuals say to mount them no higher than 6 inches above the floor.

What the sensor lights mean

Colors depend on the brand and the model, so use this as a guide and check your opener manual for the exact meaning.

LightWhat it usually means
Steady on, both sensorsWorking and lined up
Amber or yellow on one sensor (LiftMaster, Chamberlain)That sensor has power and is sending the beam
Green on the other sensor (LiftMaster, Chamberlain)Receiving the beam. Steady means lined up, blinking or off means misaligned or blocked
Red on a Genie sensorSending the beam, and it may flash for diagnostics
One light off or flickeringMisaligned, blocked or a wiring fault
No lights at allNo power to the sensors, a wiring fault or a failed opener board

Sources: Chamberlain support and Fixurge, which covers LiftMaster, Chamberlain and Genie. Some universal and older units use a different pattern.

Sunlight, frost and wiring

Sunlight on the lens

If the door fails only at certain times of day, direct sun may be hitting the lens. Shade it with a piece of cardboard, without blocking the beam. In winter the sun sits low, which can hit sensors that are fine in summer.

Frost and moisture

A wet or frosted lens can block the beam. Dry it and check the housing. Snow melt off the car can drip onto them all winter.

Damaged or loose wire

Look for a break, a chewed wire, water damage or a loose terminal. A fault on the sending side often shows as a flashing light. Wiring faults are best left to a technician.

Why you should never bypass them

It is tempting to tape over a sensor or disconnect it just to get the door closed. Do not. Photo eye sensors have been required on openers sold in the United States since 1993, and they are what stops the door from closing on a child, a pet or a car (Today’s Homeowner). If yours are failing, fix them or replace them.

Garage door sensor questions

Why does my garage door go down and then back up?

Usually the safety sensors think something is in the way. They may be dirty, knocked out of line or blocked. If the door reverses only when it reaches the floor, the travel limit or the floor seal can also be the cause.

What do the lights on garage door sensors mean?

On most LiftMaster and Chamberlain openers one sensor has an amber light, which shows it has power, and the other has a green light, which should stay steady when the two are lined up. A blinking or dark light means misalignment, an obstruction or a wiring problem. Colors vary by brand and model, so check your manual.

Can I close my garage door if the sensors are not working?

Do not bypass or tape over the sensors. They are there so the door reverses if a child, pet or car is in the way, and openers sold in the United States have been required to have them since 1993. Fix the sensors instead.

Why do my garage door sensors only fail at certain times of day?

Direct sunlight on the lens can confuse the beam. A small shade around the sensor, without blocking the other sensor, can help.

How much does it cost to fix garage door sensors in Hugo?

As an estimate, sensor alignment or replacement runs about $75 to $150, and NextLevel Garage Co. lists $85 to $100 for the sensors. Rewiring can cost more. Your written price is confirmed before we start.

When should I call a technician instead of fixing it myself?

If cleaning and re-aligning does not fix it, or you find damaged wire, water in the housing or a burning smell, stop and call. Wiring faults should be handled by a professional.
