Cold Weather and a Broken Spring in Anaheim

By Anaheim Garage Door Pros · Published October 18, 2026 · Updated October 18, 2026

What the Weather Here Does to It

Anaheim sits in a mild temperate band, so you're not dealing with the hard freeze-thaw cycles that crack steel in colder parts of the country. That's the good news. The bad news is that mild doesn't mean stable. A 45-degree night after a warm fall day still contracts steel, and a torsion spring that's already near the end of its cycle count doesn't need a deep freeze to let go - it needs one more cold snap on top of years of flexing. Most of the springs we see fail in winter weren't going to make it to spring anyway. The cold is the trigger, not the cause. What matters more here is how long that spring has been doing its job, because the metal fatigues the same way whether it's 20 degrees or 50. A spring rated for 10,000 cycles doesn't care what season it dies in - it just happens more often when the overnight temperature drops and the coil tightens. If your door feels heavier to lift on a cold morning, that's not your imagination. It's the spring losing tension right before it loses the fight entirely.

Leaving It Alone

A lot of homeowners hear a spring go and figure the door still opens with the opener, so it can wait. That works for a few days, sometimes longer, but the opener isn't built to do a spring's job. It's built to do the last ten percent of lifting a door that's already balanced. Without a spring sharing the load, the opener motor and the drive gear take the full weight every cycle, and that's not what they're rated for. On a house with a door from the 1960s-70s stock that's common in this area, the opener itself may already be older, and asking it to lift unassisted is a fast way to burn it out on top of the spring you already need to replace. The honest limitation here: once the opener strains like this for more than a few openings, we can't always tell you it's fine - sometimes you're now looking at two repairs instead of one. If a spring breaks, the safest and cheapest path is to stop using the opener until the spring's replaced, not to keep pushing the button.

The Situation

Anaheim's housing stock runs from 1938 to 2007, with a median build year around 1969, and most of what's on the ground across the area's named neighborhoods is 1960s-70s construction. That matters for springs because torsion hardware from that era wasn't always upgraded when the door was. A lot of these garages still run original-spec torsion tube setups, or a replacement spring that was sized for the original wood door and never resized when someone swapped in a heavier insulated steel one later. That mismatch shows up as a spring that's working harder than it should for its rated cycle life, and it's the kind of thing a cold snap exposes rather than causes. If your house falls into that median build window, there's a decent chance the hardware behind the drywall predates you living there, and nobody's looked at the spring sizing since.

The Common Mistake

The mistake we see most is someone replacing just the broken spring on a double door and leaving the other one alone because it "still looks fine." Springs on a two-spring setup are almost always close in age and cycle count - they were installed together, they've flexed the same number of times, and one failing in cold weather usually means the other is right behind it. Replacing one and not the other means you're back out here in a matter of weeks, sometimes days, once the second one lets go under the exact same conditions. It costs less time and less money to do both at once than to pay for two separate calls on the same door.
