The door suddenly got heavy
The opener is the victim, not the villain.
When a spring fails, the opener often gets blamed because it is the part making noise. But the opener is usually trying to lift a door the spring should be carrying.
A broken spring can sound like a firecracker in the garage. Sometimes there is no dramatic moment; the door just starts lifting crooked, opens a few inches, or drops harder than it used to.

Spring systems
Springs are cycle counters.
Torsion springs above the door
Look from a safe distance for a visible gap in the coil above the opening. The repair also involves checking the shaft, drums, cables, bearings, and door balance.
Extension springs along the tracks
These stretch on the sides of some doors. Pulleys, safety cables, cable wear, and side-to-side balance matter as much as the spring itself.
One spring or two?
Two-spring doors need a matched lift system. If one spring failed, the other may be close enough in age and cycle wear that it should be discussed honestly.
Why Yuma makes it obvious
Heat is not the whole story, but it exposes weak parts.
Springs break from cycle wear. Every open and close counts: work trucks leaving early, kids coming home, errands, deliveries, late-night returns. When rollers are dry, tracks are gritty, or the door is dragging, the lift system works harder.
Hot garages make the whole system less forgiving. Seals get stiff, opener controls get cranky, plastic parts age, and a spring that was already near the end can finally show itself on the hottest week of the year.
Typical spring range
$150-$540 typical spring range
Door size, spring type, number of springs, cable condition, drums, bearings, access, and emergency timing can change the price.
Ask About The SpringWhat the repair should include
Spring work should end with a balanced door.
The door should be checked by hand before the opener is trusted again. That means the cables sit right, both sides lift evenly, the door does not slam, and the opener is not doing the spring work alone.
Do not wind, stretch, clamp, or muscle the spring. If a car is trapped inside, say that first when you call. If the door is stuck open, keep everyone clear until it is secured.

Questions
Spring repair questions
Can I replace a garage door spring myself?
It is not a good DIY repair. Springs are under high tension and can cause serious injury.
How do I know if the spring broke?
Look for a gap in the spring, a loud snap, a very heavy door, or an opener that starts but cannot lift the door.
What should I do before calling?
Stop using the opener if the door is stuck, crooked, heavy, dragging, or making a new sound. Call with what happened first and whether the door is open or closed.
Can Yuma heat and dust make this worse?
Yes. Heat, dust, sun exposure, dry seals, worn rollers, weak springs, and sensor glare can all make garage door problems show up faster.
Did the spring snap?
Call with the door size if you know it, whether the door is open or closed, and whether you see a gap in the spring or a loose cable.
