Why Safety Sensors Are Critical

Safety sensors prevent the garage door from closing on people, pets, or vehicles. Federal law requires all garage door openers manufactured after 1993 to have safety sensors. Never bypass or disable your sensors!

Signs Your Safety Sensors Need Repair

Recognize these warning signs? Call us immediately for safety sensor repair – serving Chicago and the Chicago suburbs

Door Won't Close

Your garage door starts closing but immediately reverses back open. This is the primary sign of sensor issues.

Blinking Sensor Lights

One or both sensor lights are blinking, indicating misalignment or obstruction issues.

No Sensor Lights

The sensor lights are completely off, indicating a power or wiring problem that needs immediate attention.

Intermittent Operation

Door closes sometimes but not always - inconsistent sensor performance indicates alignment or connection issues.

Dirty or Foggy Lenses

Sensor lenses are covered with dirt, dust, or condensation blocking the infrared beam.

Must Hold Button

You have to hold down the wall button to close the door - this bypasses sensors and is extremely dangerous!

Misaligned Sensors

Sensors are visibly crooked, knocked out of position, or not pointing directly at each other.

Loose Wiring

Visible loose, damaged, or corroded wiring connections at the sensors or opener unit.

SAFETY WARNING

Never bypass or disable your safety sensors!
Bypassing safety sensors is illegal and extremely dangerous. It can result in serious injury, death, or property damage. Federal law requires working safety sensors on all garage door openers. Always call a professional for repairs.

Safety Sensor Repair FAQs

Get answers to common safety sensor repair questions
How long does sensor repair take?
Most sensor repairs are completed in 20-45 minutes. This includes diagnosing the issue, repairing or replacing sensors, aligning them properly, and testing everything thoroughly. Sensor replacement typically takes 30-60 minutes for complete installation.
If your garage door starts closing but immediately reverses, the most common cause is misaligned or malfunctioning safety sensors. The sensors create an invisible beam across the door opening – if anything blocks this beam or the sensors aren’t aligned, the door won’t close as a safety feature.
Blinking sensor lights typically indicate misalignment between the two sensors. One sensor should have a solid green light, and the other should have a solid red/orange light when properly aligned. Blinking lights mean the sensors aren’t “seeing” each other and need professional alignment.
Absolutely not! Bypassing safety sensors is illegal and extremely dangerous. Safety sensors are required by federal law to prevent serious injuries and death. Never attempt to bypass or disable your sensors. Always call a professional for proper repairs.
Yes! We offer same-day safety sensor repair service throughout Arlington Heights and surrounding areas. Most customers get service within 1-2 hours of calling. Our trucks are fully stocked with sensors for immediate replacement if needed.
Signs you need sensor replacement include: no lights on sensors, cracked or damaged sensor housings, corroded wiring, sensors that won’t stay aligned, or sensors over 10 years old. Our technician will inspect and recommend repair vs. replacement based on condition.
We offer a lifetime warranty on our premium sensor replacements and 1-year warranty on sensor repairs. All labor is warranted for 1 year. If anything goes wrong with your sensors, we’ll fix it at no additional cost.
