That Annoying Reversal: Why Your Garage Door Won’t Stay Down & How to Fix It
Okay, let’s talk about one of the most frustrating garage door gremlins: you hit the button to close it, it starts going down… and then bam, it reverses right back up like it’s scared of the dark. Been there? Yeah, we’ve all groaned at that one. It’s not just annoying—it’s a safety feature screaming, “Something’s wrong!” But don’t panic. We’re going to walk through exactly why this happens and how you can troubleshoot it like a pro. (And yes, if things get hairy, we’ll tell you exactly when to call us at Kald Galt Garage Doors here in Calgary.)
Why Your Garage Door Thinks It’s a Yo-Yo
Modern garage doors are smarter than we give them credit for. They’ve got built-in safety systems designed to stop and reverse if they sense an obstacle (like your car, your kid’s bike, or… well, you). If your door reverses when closing, it’s usually one of these culprits:
- The Safety Sensors: Those little eyes near the floor? They’re talking to each other. If they’re misaligned, dirty, or blocked, your door thinks there’s a phantom obstacle.
- Force Settings Gone Wild: The motor has a “force” setting telling it how hard it can push down. If it’s too low, the door hits resistance (like sticky rollers) and gives up.
- Track Troubles: A bent track, grimy rollers, or a rogue pebble can jam things up.
- Spring or Cable Drama: Worn springs or frayed cables create uneven tension, tricking the system.
- Limit Switch Shenanigans: This tells the door where “down” actually is. If it’s off, your door stops short.
Let’s Play Detective: Your Step-by-Step Troubleshooting Guide
Step 1: Safety First (Seriously, We Mean It)
Unplug the opener. No, really. Garage door springs are under insane tension. If you’re poking around cables or springs, call a pro. We’ve seen DIY attempts go sideways (and it ain’t pretty). For everything else? Let’s dive in.
Step 2: The Sensor Shuffle (H3)
Those little LED sensors on either side of your door (about 6 inches off the floor) are the usual suspects. Here’s how to check them:
- Clean ‘Em Up: Wipe the lenses with a soft cloth. A cobweb or dirt speck can ruin their day.
- Align ‘Em Right: Both sensors must “see” each other. Look for a steady light (usually green) on both. If one’s blinking or off, gently adjust the bracket until both lights glow steady. A knocked bracket is super common!
- Check for Obstructions: Move that box, shovel, or garden gnome blocking the beam.
FYI, if your sensor lights are out even after cleaning/aligning? The wiring might be chewed by rodents (classic) or damaged. Time for a garage door technician.
Step 3: Test the Force Settings (H3)
Your opener has adjustable force settings. Too low = door reverses too easily. Too high = it could crush something. We never recommend cranking force high to “fix” a reversal! That’s a safety risk. Instead:
- Find the force adjustment knobs on your opener (labeled “Open Force” / “Close Force”).
- Turn the “Close Force” knob slightly clockwise (maybe 1/8 of a turn).
- Test the door. Repeat if needed, but stop if it needs more than a tiny tweak. If you’re cranking it way up, you’re masking a bigger problem (like binding tracks).
Step 4: Inspect the Tracks & Rollers (H3)
A sticky roller or bent track makes your door work harder, triggering a reversal.
- Look for Dents: Shine a flashlight down the track. Even a small bend can derail things.
- Check the Rollers: Manually lift the door halfway. It should glide smoothly. Grinding? Sticking? Rollers might be shot.
- Clean and Lube: Wipe tracks clean of debris. Apply garage door lubricant (not WD-40!) to rollers, hinges, and tracks.
Pro Tip: If your track looks like it survived a demolition derby, garage door track repair isn’t just smart—it’s essential. For commercial overhead door repair in Calgary, this is doubly critical; bigger doors mean bigger headaches if tracks fail.
Step 5: When to Wave the White Flag (and Call Us)
Some fixes need expertise. Like:
- Garage door spring replacement: Those coils are lethal. If your door feels heavy manually or springs look stretched/cracked, don’t touch them.
- Garage door cable replacement: Frayed cables? Immediate red flag.
- Persistent reversal after all troubleshooting: Could be a failing motor board or internal issue.

Quick Reference: Common Reversal Causes & Fixes
| Symptom | Likely Culprit | DIY Fix? | Call a Pro When… |
|---|---|---|---|
| Door reverses immediately | Misaligned/dirty sensors | Clean/align sensors | Wiring damaged, sensor failure |
| Door reverses near floor | Force setting too low | Slight force increase | Door binds, needs mechanical repair |
| Door jerks then reverses | Binding track/rollers | Clean/lube track | Track bent, rollers seized, cable issue |
| Door reverses randomly | Failing limit switch | Adjust down limit | Switch faulty, motor issues |
| Door heavy manually | Broken spring/cable | NO | Spring/cable replacement needed ASAP |
FAQs: Your Burning Questions, Answered
1. “I fixed the sensors, but it still reverses! What now?”
Double-check track alignment and roller freedom. If those are good, your force settings might need a tiny adjustment, or the limit switch (which tells the door how far down to go) could be off. If DIY fails, it’s technician time—could be internal motor issues.
2. “Is reversing dangerous? Can I just override it?”
Overriding safety features (like holding down the wall button) is risky. The reversal is warning you of a problem—ignoring it could damage your opener, door, or worse, injure someone. Fix the root cause.
3. “How much will professional repair cost in Calgary?”
Cost varies. Sensor realignment? Often minimal if that’s it. Spring replacement? More, due to parts and safety labor. At Kald Galt Garage Doors, we provide upfront price estimates because nobody likes surprises. Commercial garage door repair costs more due to scale, but we keep it fair.
Wrapping It Up: Don’t Let Your Door Win
Most reversals are fixable with a little patience—sensors, lube, and minor adjustments solve 80% of them. But when you hear grinding, see cable frays, or just feel out of your depth? That’s what we’re here for. Trying to DIY a spring replacement is like juggling chainsaws :/. Not worth the ER trip.
