Garage Door Won't Close in Winter? 4 Quick Fixes for Edmonton Homeowners

1. Snow & Salt Crust on Safety Photo-Eyes: Your LiftMaster or Chamberlain safety sensors sit 5 inches off the slab—right where slush sprays off your tires. Wipe both lenses with a microfiber cloth.

2. Low Winter Sun Glare: In December and January, Edmonton's low sun angle shines directly into south- and west-facing garages, blinding the receiving eye. Swapping the sender and receiver sides or adding a sun shroud solves this instantly.

3. Concrete Slab Frost Heave: When the concrete apron heaves 1/2 inch upward in deep freeze, the door hits the floor slightly earlier than its summer travel limit and thinks it hit an obstruction.

4. Stiffened Rollers Triggering Force Reversal: Modern DC openers monitor amperage draw. If old grease freezes, the opener trips its safety reverse.
