Why do garage door springs break in Minneapolis winters?
Springs wear out by cycles. Each time the door goes up and down, the spring winds and unwinds. Over time the metal tires and snaps. Cold weather can bring that moment sooner, because steel becomes more brittle as temperatures drop and a long freeze in Minneapolis can finish off a spring that was already near the end of its life.
Several things make winter harder on springs:
- Ice that holds the bottom seal to the floor, so the springs and the opener pull against a frozen door.
- Frost and moisture inside the panels, which can add weight and upset the balance.
- Grease that thickens in the cold and makes rollers and hinges drag.
- Heavy use, since many homes use the attached garage as the daily entry and the door cycles several times a day.
