Garage door safety sensor repair in Mississauga

The photo eyes on a garage door sit about six inches above the floor, and in Mississauga six inches is under the waterline of a bad summer storm. When the door starts down and goes straight back up after heavy rain, the pair near the floor is the first suspect. The Mississauga branch repairs and replaces them from Unit 14, 1495 Bonhill Rd, off Dixie Road: call (289) 975-9045 at any hour, or send the contact form with a photo of each eye. How the pair works, and the alignment and lens faults behind most calls, is on the sensor repair page.

Three storms since 2013

Toronto Pearson, the weather station inside Mississauga, took 126.0 mm of rain on 8 July 2013, the wettest day in its 1991 to 2020 normals, and most of it inside 10 hours. The City of Mississauga has counted two more since: more than 106 mm on 16 July 2024, and upwards of 170 mm in some parts of the city across 17 and 18 August 2024.

Water that runs down a driveway into a garage finds the lowest things in it first. The eyes, their brackets and the thin wire from each one back to the motor head all sit along the bottom of the tracks, so a garage that took ten centimetres of water has had its sensors submerged even if nothing else in it was touched.

After the water goes down

Switch the opener off or unplug it before touching anything at floor level. Let the eyes and their wire dry out completely, then power up and read the lights. A pair that comes back with both lights steady is working for now. Water leaves minerals and corrosion inside the housing, though, and a sensor that was under water can work for a few weeks and then start flickering or dropping out. When that happens, replace the pair rather than chase the fault, and check the wire run at the same time: a wet wire staple rusts, and rust cuts through thin insulation.

The eyes have to suit the opener, since Chamberlain, LiftMaster and Craftsman share one platform and Genie runs its own, so photograph the label on the motor head along with the eyes. Repairs are booked same day.

The rest of the year

Outside storm season the Mississauga faults are the ordinary ones: slush off the car drying to a salt film on the lens, and brackets at ankle height knocked out of line. A dry cloth across both lenses and a bracket turned until the light holds steady fix most of them without a visit. If both lights are steady and the door still reverses, the fault has moved to the opener, and opener repair in Mississauga takes it from there.

Out across the GTA

Storm water does not stop at the city line, and the branch takes sensor calls wherever it covers. Garage door repair in Brampton shares the same creeks and the same summer storms, garage door repair in Etobicoke is just east across Etobicoke Creek, and garage door repair in Oakville is along the lake to the west. From any of them, the first checks are the same and cost nothing: power off, lenses dry and clean, both lights read.

When a pair does need replacing, both eyes are changed together, and they are matched to the opener from the label on its motor head. The new pair goes back at the same height, about six inches, with the wire run up the wall clear of the floor and clipped rather than stapled, so the next flood or the next shelf bracket has less to damage.
