Garage door springs rarely fail out of nowhere. They fatigue over thousands of cycles, and they usually warn you first.

Four signs worth acting on. The door suddenly feels heavier than normal. The opener hums, struggles, or stops mid-travel. The door moves unevenly or looks slightly crooked. Or you can see a visible gap in a torsion spring.

Any of those means stop cycling the door. And lubrication won't stop normal metal fatigue. What actually helps is catching binding rollers and balance problems early, so the springs aren't carrying extra stress on every trip.

Door starts down and reverses? Check the photo-eyes before you blame the opener.

Those two small sensors near the floor are the most common reason a door won't close. Clean the lenses gently — dust and cobwebs are enough to trigger a reversal. Make sure the brackets haven't been bumped or twisted. The indicator lights should hold steady, not flicker. Then follow the wires and look for pinched or nicked spots.

Sensors clean and aligned but still reversing? The next suspects are door balance and travel limits, in that order.

A lot of "my opener is dying" calls turn out to be a door balance problem.

Here's the test. With the door closed, pull the emergency release cord to disconnect the opener. Lift the door by hand and stop it partway. It should feel manageable and stay roughly where you left it. If it slams down, shoots up, or feels unusually heavy, the springs aren't carrying their share. The opener has been covering the difference.

If it fails that test, stop using the door and have the spring system checked. Full inspection walkthrough:

Two things quiet most noisy garage doors: tightening hardware and using the right lubricant.

Skip the WD-40 - it's a solvent and doesn't provide lasting lubrication. Use a silicone or lithium-based garage door spray. Good spots: hinges, roller stems, bearing plates, and the top of the chain or belt rail. Leave the tracks alone — they should be clean, not slick. Never spray the photo-eye sensors.

If grinding or popping continues after lubrication, stop there. That usually points to worn rollers, a track problem, or springs. Spring work is not a DIY job.
