Why Garage Door Springs Break in Minnesota Winters (And How to Prevent It)

If you've lived through a Minneapolis winter, you know our garage doors take a beating. The single most common cold-weather failure we're called out for is a broken torsion spring — and it almost always happens on the coldest morning of the year, right when you're trying to leave for work. Here's why it happens and what you can do about it.

Why Cold Weather Breaks Garage Door Springs

Your springs are wound steel under enormous tension, and steel behaves differently in the cold. Three things work against them every Minnesota winter:

• Metal contracts and gets brittle. As temperatures drop below freezing, steel becomes less flexible and more prone to snapping — especially springs that already have thousands of cycles on them.
• Grease thickens. The lubricant on the spring and rollers stiffens in the cold, so the door is harder to move and the spring works harder on every lift.
• Sudden temperature swings. Our freeze-thaw cycles cause repeated expansion and contraction, which accelerates metal fatigue over time.

A spring that was perfectly fine in October can reach the end of its cycle life on a −10°F January morning. That loud "bang" some homeowners hear from the garage overnight is often a spring letting go.

Warning Signs Your Spring Is About to Go

Springs rarely fail without hints. Watch for:

• The door feels heavier than usual or opens slowly.
• The door opens a few inches, then stops.
• You see a visible gap in the coil of the spring above the door.
• The opener strains, hums, or reverses without lifting.
• The door closes faster or harder than normal.

How to Prevent Winter Spring Failures

You can't beat physics, but you can dramatically lower your odds of a mid-winter breakdown:

• Get a fall tune-up. Before the first freeze, have a technician check spring tension, balance the door, and lubricate everything with a cold-rated garage door lubricant (not WD-40).
• Lubricate the springs and rollers every few months with a silicone or lithium-based spray made for garage doors.
• Upgrade to high-cycle springs. Builder-grade springs are often rated for only ~10,000 cycles. High-cycle springs last far longer — a smart investment in our climate.
• Replace both springs together. If one breaks, the other is close behind. Replacing the pair keeps the door balanced.

Already Have a Broken Spring?

If your door won't open and you suspect a spring, don't wait — and don't keep hitting the opener button. Our technicians carry common torsion and extension springs on every truck, so we can usually get you back up and running the same day.
