Torsion Springs - FAQs & Troubleshooting

Q: How do I choose the right torsion spring?

Match specs to the spring that came off your door. You need inside diameter, wire size, overall length, and wind direction. Using different specs can cause balance issues or hardware damage.

Q: How do I measure my existing spring?

Release any remaining tension, then measure the inside diameter, identify wind direction, count 20 coils for wire size, and measure total relaxed length including broken pieces.

Q: Can I use a torsion spring with the wrong wind?

Sometimes. On single spring systems, if the length, diameter, and wire size are correct you can move the spring to the opposite side of the center bracket. You may need to shift the anchor bracket for clearance. This does not apply to two spring setups.

Q: How long do torsion springs last?

Standard torsion springs are rated for about 10,000 cycles. One cycle is one full open and close. This usually equals 7 to 10 years of average use. Heavy use or poor maintenance shortens lifespan.

Q: Why should I replace both torsion springs if only one is broken?

Both springs share the load. If one breaks the other is fatigued and near the end of its life. Replacing both keeps the door balanced and prevents a second failure soon after.

Q: Can I upgrade to a high cycle torsion spring?

Yes, but it requires converting to a different wire size and length to keep the lift rating correct. This is not a direct swap. Contact us for help with a proper conversion to high cycle springs.

Q: What safety steps should I follow when replacing torsion springs?

Unwind old springs fully before removal, clamp the door in place, and use protective gear. Keep clear of the cones and set screws while tension is present. If unsure, seek professional help.

Q: What tools do I need to replace torsion springs?

You will need a pair of winding bars, a ratchet set, wrenches, vise grips or clamps, and a tape measure. Always use proper winding bars, not screwdrivers or improvised tools.

How do I choose the right torsion spring?

Match the replacement to the spring that came off your door. Gather these four items from the broken spring, not from the opener:

Inside Diameter (example: 1.75" or 2")
Wire size (measure 20 coils and convert using a chart)
Overall length (relaxed length, include broken pieces)
Wind direction (left wind or right wind)

Using different specs can throw the door out of balance and damage hardware. Replace with like for like specs.

How do I measure my existing spring?

Measure from the spring you removed. If any tension remains, release it safely before measuring.

Step 1: Inside Diameter Confirm the cone stamping or measure the inner opening.

Measuring torsion spring inside diameter

Example: measuring the inside diameter of a torsion spring.

Step 2: Wind Direction Look at the winding cone. Left wind appears to wrap counter clockwise at the cone. Right wind wraps clockwise. Installed position is opposite sides of the center bracket.

Identifying torsion spring wind direction

Example: identifying left wind vs right wind spring direction.

Step 3: Wire Size Count 20 coils and measure end to end. Convert that length to a wire size using a chart.

Wire size chart: convert your 20 coil measurement into a wire size.

Step 4: Overall Length Measure the relaxed spring length, include broken pieces, and round to the nearest inch.

Example: measuring the full unwound length of a torsion spring.

Can I use a torsion spring with the wrong wind?

If you ordered the wrong wind but the length, diameter, and wire size are correct, you may be able to use it on a single spring system. Remove the spring and install it on the opposite side of the center support bracket. You may need to move the spring anchor bracket to create space for the spring to fit correctly.

This applies only to single spring setups. For two spring systems, each spring must have the correct wind.

How long do torsion springs last?

Most standard torsion springs are rated around 10,000 cycles. One cycle is one full open and close. With average daily use, this is often 7 to 10 years. Heavy doors or higher daily cycles will shorten life. Keeping rollers and hinges in good condition helps reduce strain on the spring system.

Why should I replace both torsion springs if only one is broken?

Paired springs share the load. If one breaks, the other has already seen the same number of cycles and is likely near the end of its life. Replacing both keeps the door balanced and reduces the chance of a second failure soon after the first repair.

Can I upgrade to a high cycle torsion spring?

Yes, but it is not a simple one to one swap of your old dimensions. To increase cycle life, the spring specification must be converted to a different combination of wire size and length while maintaining the correct lift for your door. Contact us for help with the conversion so you get the right high cycle spring for your setup.

What safety steps should I follow when replacing torsion springs?

Always unwind the old springs completely before removal. Secure the door with clamps at the tracks. Keep hands and tools clear of the cones and set screws while tension is present. Wear eye protection and heavy gloves. If you are not comfortable with these steps, seek professional service.

What tools do I need to replace torsion springs?

Core items include a pair of winding bars, a ratchet and socket set, open end wrenches, locking pliers or clamps, and a tape measure. Only use proper winding bars for winding and unwinding. Do not use screwdrivers or improvised tools.
