Garage door safety sensor repair in Georgetown costs $120–$180 + tax. Realignment and cleaning of existing sensors is at the lower end; full photo-eye sensor pair replacement with rewiring is at the upper end. The visit includes testing the auto-reverse safety feature, inspecting the wiring run back to the opener, and verifying the door reverses correctly on obstruction.

Free service call included with any repair. 1-year parts and labor.

A door that won't close (and often reverses with the opener lights flashing) is almost always a safety sensor problem. The two photo-eye sensors at the base of the tracks must "see" each other. If the beam is broken or misaligned, the opener refuses to close as a safety measure.

Common causes in Georgetown:

• A sensor knocked out of alignment by a bike, bin, or bump
• Dirty or fogged lenses (condensation is common in our winters)
• Sun glare hitting a west-facing sensor in late afternoon
• A damaged or chewed wire (rodents, lawnmowers, string trimmers)
• A failed sensor that needs replacement

Each photo-eye sensor has an LED. On most LiftMaster and Chamberlain units: the sending sensor shows a steady amber/yellow light (it's always on when powered). And the receiving sensor shows a steady green light only when it's properly aligned and "seeing" the beam.

If the green light is off or blinking, the sensors are misaligned, blocked, or one has failed.

Genie and other brands use similar indicators. A blinking light is your signal to clean the lenses and gently adjust the sensor angle. If it stays blinking, call us for repair in Georgetown.

You can try basic realignment: gently loosen the wing nut holding the sensor bracket, adjust the angle until the receiving sensor's LED glows steady green, then retighten. Clean both lenses with a dry microfiber cloth first — condensation and dust cause most false readings in Georgetown. If the LED won't stay steady after cleaning and realignment, the problem is deeper: a damaged wire, corroded connection, or failed sensor.

Those require testing the wiring continuity back to the opener, which needs proper tools. Don't bypass or disable the sensors — they're a critical safety feature and required by code.

Yes — photo-eye safety sensors have been federally mandated on all residential garage door openers manufactured since 1993 (under U.S. UL 325 standards, which Canadian manufacturers follow). They prevent the door from closing on a person, pet, or vehicle.

Disabling or bypassing them is unsafe and may violate the Ontario Building Code Act safety provisions and void your insurance in the event of an injury. If your sensors are failing, the correct fix is repair or replacement — never bypassing. We restore full code-compliant safe operation on every Georgetown sensor service.

Our sensor service in Georgetown includes a full safety test: we verify both sensor LEDs, check beam alignment, and run the auto-reverse test. Placing a 1.5-inch-high object (a roll of paper towel) in the door's path to confirm the door reverses right away on contact, as required. We also test the wiring continuity from each sensor back to the opener terminals, inspect for corrosion or damage.

And confirm the opener's logic board reads the sensor signal correctly. Only when all tests pass do we consider the repair complete.

Georgetown winters are hard on photo-eye sensors. Condensation forms on the lenses as warm garage air meets cold sensor housings, fogging the beam and causing false reversal. Road salt and slush splash onto the low-mounted sensors, corroding the lens and the wire terminals.

Sub-zero temperatures can also make older sensor wiring brittle, leading to intermittent faults. We see a spike in sensor calls across Georgetown every January and February. A quick cleaning and a weatherproofing check during annual maintenance prevents most winter sensor problems.

Premature reversal is usually one of two issues: a sensor problem or a misadjusted close-force/travel setting. First check the sensors — clean both lenses and confirm the receiving LED is steady green. If the sensors look fine, the opener's down-travel limit may be set too far (the door hits the floor and reverses thinking it hit an obstacle), or the close-force is set too sensitive.

Both adjustments are part of our sensor and opener service in Georgetown. If realignment and adjustment don't resolve it, the photo-eye pair likely needs replacement.
