What Should I Do if My Garage Door Breaks Over the Winter?
A broken garage door is a major headache, but in the middle of an Ontario winter, it’s a security and safety emergency. Freezing temperatures can make metal components brittle and cause moving parts to seize, leaving your home exposed to the elements.
If your door fails during a cold snap, follow these steps to troubleshoot safely and avoid further damage.
1. Check if the Door is Frozen Shut
One of the most common “breakdowns” in winter isn’t a mechanical failure at all—it’s ice. If water pools at the base of your door and freezes, the bottom rubber seal (weatherstripping) will stick to the concrete.
The Danger: Forcing the door open with your automatic opener can burn out the motor or rip the weatherseal.
The Fix: Gently chip away at the ice with a plastic scraper or use a heat gun (on a low setting) or a hair dryer to melt the ice along the bottom of the door. Avoid using boiling water, as it can refreeze almost instantly and create a skating rink in your driveway.
2. Listen for “The Snap” (Broken Springs)
Cold weather causes metal to contract and become brittle. This is the time of year when garage door springs are most likely to break.
The Sign: You might hear a loud “bang” like a gunshot from the garage. If the spring is broken, the opener will struggle or fail to lift the door entirely.
Safety Warning: Do not attempt to open the door. A door with a broken spring is dead weight and can crash down, causing serious injury.
3. Clear the Tracks and Sensors
Snow and ice can easily build up inside your garage door tracks or block the safety sensors.
Track Obstructions: Ice in the tracks can force the rollers out of alignment. Clear any visible snow or grit with a stiff brush.
Sensor Interference: If your door starts to close and then reverses, check the photo-eye sensors at the base of the tracks. Wipe away any frost, snow, or cobwebs that might be breaking the invisible safety beam.
4. Check the Lubricant
Standard grease can thicken and become “tacky” in sub-zero temperatures, making it harder for the rollers to move.
The Fix: If the door is moving slowly or making a grinding sound, use a specialized silicone-based lubricant. Avoid WD-40, which acts as a degreaser and can actually make the problem worse over time.
5. Test the Manual Release
If you have power but the motor is humming without moving the door, pull the red emergency release cord to operate the door manually.
Caution: Only do this if the door is in the fully closed position. If the door is partially open and a spring is broken, pulling the release cord could cause the door to slam shut.
