Why does my garage door reverse right after touching the floor?

That after-contact reversal is the force sensor giving up: the door feels heavier than the opener's setting allows, which points to a force setting set too low, a thick new bottom seal dragging, or springs that have lost tension with age. Reversing BEFORE contact instead is the down-limit switch — a different adjustment and a different cost.

Can I adjust garage door opener force and limit settings myself?

On openers made after roughly 2011, yes — the knobs are designed for it. Work in quarter-turns: force up until the door seats without straining, travel down until it touches the floor, and test a full cycle between every adjustment, three rounds maximum. If the door grinds, strains or the screws change nothing, stop — the underlying cause is mechanical.

How much does it cost to fix a garage door that reverses?

Reversal repairs are priced by the failed part and the visit scope: a limit-switch or force adjustment is billed as a standard service call, re-mounting any broken sensor hardware is quoted by brand and bracket condition, and re-tensioning or replacing weak springs is priced by spring type, cycle rating and door weight as a pair. The adjustment visit alone resolves roughly half of the calls we attend — start there before assuming springs.

Is a garage door that won't stay down a spring problem?

Sometimes — and there is a 10-second check: with the door halfway open (opener off), a balanced door holds its position; one that drifts downward is telling you the springs have lost tension. A door that holds level but still reverses is instead a settings or sensor issue. Springs are the one cause on this list that is never DIY, at any setting.

How long does it take to fix a reversing garage door?

The settings themselves take minutes: a technician performs the force and limit adjustments and a full safety test inside a standard hour visit. Sensor re-mounts add 15-20 minutes; spring replacement runs 45-60 minutes. Most reversal calls leave resolved the same visit — it's why the adjustment call-out is worth booking rather than guessing.

Quick Answer

Quick Answer: Why Won't My Garage Door Stay Down?

In Toronto service calls, a garage door that won't stay down is most often uneven spring tension — one spring fatigued past its partner, so the door fights itself at the floor. Beyond that: a down-force setting too light, a down-limit set past the floor, worn springs that can't hold the door seated, or track friction that's made the door 'heavier'. Different failure from a garage door that won't close all the way — this one finishes the close and loses it. Adjustments are billed as a standard service visit; spring work is priced by spring type, cycle rating and door weight.

The 5 causes of a garage door that won't stay down, with tell-tale signs and whether each is DIY-safe
Cause	Tell-tale sign	DIY-safe?
1. Uneven spring tension — the #1 cause	Pops back the moment it seats · door sits crooked at rest	No — call
2. Opener down-force set too light	Reverses right at the floor, worse in cold weather	Yes
3. Down-limit set past the floor	Door touches, strains, then bounces back up	Yes
4. Worn springs that can't hold it down	Creeps back open minutes or hours after closing	No — call
5. Track friction making the door 'heavier'	Stiff, scraping final foot of travel	No — call

The Decision Tree

First: Which Reversal Do You Have?

Precision is the whole game — most repair sites blur 'won't close' and 'won't stay down', but they're different failures with different fixes.

Watch one full cycle — door in view, opener light in view — and note the exact moment it comes back. The timing is the diagnosis: a door that reverses on contact is fighting its settings or its springs; one that creeps open minutes or hours later never truly finished its close.

The fork

Does it come back the moment it seats — or minutes to hours later?

Branch A

It comes back immediately

The door reverses the moment it seats — or just before it touches. That's the door fighting its own settings or its springs: tension pulling unevenly, or a force setting that gives up on contact.

Suspects, in order:

#1 — Uneven spring tension
#2 — Down-force set too light
#3 — Down-limit set past the floor

A settings & tension fight — try the two-adjustment fix

Branch B

It creeps back later — minutes or hours

The door closes, seats, looks finished — then drifts open an inch or a foot. The close never truly ended: a limit that has drifted, or springs that no longer hold the door seated.

Suspects, in order:

#4 — Worn springs that can't hold it down
A limit that's drifted — door stops just short of closed
#5 — Track friction changing the door's weight

Drift & imbalance — confirm with the balance test below

10s

The 10-second balance test

Close the door fully, pull the red emergency-release handle, and lift the door by hand to halfway. A balanced door holds — the problem is settings. A door that drifts either way has a spring problem, and the knobs won't save it. If the door feels heavy or wants to crash down as you lift, re-latch and skip the test: that's your answer.

Drifts either way = springs — stop adjusting

When the answer is the opener, not the door

Force knobs, limit switches, logic boards — that's the daily bread of our garage door opener repair in Toronto crews. Adjustment visits are same-day, and the two knobs are the first thing every tech reaches for.

Diagnosis

The 5 Causes, Most to Least Common

Ranked by our 2026 GTA call-out records — each cause gets its own breakdown below.

Uneven spring tension — the #1 cause

Two springs share one job, but they rarely age in lockstep: one fatigues a season ahead of the other and the door starts closing a fraction crooked. The heavy side settles, the light side lifts, and the opener reads the tug-of-war as an obstruction — the door pops back the moment it seats. The balance test in the decision tree confirms it.

Pops back the moment it seats · door sits crooked at rest

Professional repair only: tensioned springs are off-limits — that's garage door spring repair in Toronto territory, never a DIY at any setting.

Opener down-force set too light

The force sensor decides how hard the door may push before the opener gives up. A setting that was fine in July trips in January — cold grease, aging springs and a new bottom seal all make the door 'feel' heavier through the last inch. Two knobs on the opener motor unit fix it, a quarter-turn at a time.

Reverses right at the floor, worse in cold weather

DIY-safe: the two-adjustment walkthrough below is this fix — quarter-turns, test cycles, three rounds max.

Down-limit set past the floor

The limit tells the opener where 'closed' is. Set it past the floor and the opener keeps pushing after the door bottoms out — the door loads against the concrete and rebounds back up, sometimes with an audible bounce. One screw fixes it; if the screw spins without effect, the switch assembly is worn.

Door touches, strains, then bounces back up

DIY-safe: one screw, a quarter-turn at a time — the walkthrough below covers it.

Worn springs that can't hold it down

Late in their 10,000-cycle life, springs lose the muscle to keep the door seated square. The close looks finished — then the door drifts, an inch or a foot, as the imbalance slowly wins. If yours creeps open overnight, this and a drifted limit are the two suspects, in that order.

Creeps back open minutes or hours after closing

Professional repair only: same rule as cause #1 — the spring system stays untouched. Book the balance test and let a tech quote the pair.

Track friction making the door 'heavier'

Dry, gritty tracks, a slight bend, a fresh thick bottom seal or an asphalt heave at the threshold all add drag through the final foot of travel — the door 'weighs' more than its force setting allows. Cleaning the tracks is DIY-safe; bends, seals and threshold ramps are workshop work.

Stiff, scraping final foot of travel

Professional repair: track, seal and threshold work rides along with a service visit — forcing the door only bends the rails further.

Safe DIY: The Two-Adjustment Fix

If any garage door won't stay down fix is safe to try yourself, it's this one — two controls, quarter-turn increments, a test cycle between each. Springs stay untouched.

Warning — quarter-turns only: adjust force and limit settings a quarter-turn at a time, with a full cycle between turns, three rounds maximum. And don't keep re-running a reversing door: the auto-reverse is telling you something is wrong. Repeated cycles can burn out the motor or — if the cause is spring tension — drop the door hard. Two attempts to diagnose, then stop and call.

Find the two controls

The force and travel-limit screws sit on the back or side of the opener motor unit — two recessed screws under a light plastic cover, marked FORCE and TRAVEL or LIMIT. A stepladder and a flat screwdriver are all you need.

Marked FORCE and LIMIT (or TRAVEL)

Force knob: a quarter-turn up

Turn the down-force control one quarter-turn toward more, then run a full cycle. Seats without straining? Done. Still pops back? One more quarter-turn — three rounds maximum, a full test cycle between every turn.

Quarter-turn, cycle, repeat — max three

Limit screw: a quarter-turn back

If the door strains or bounces at the floor, back the down-limit off a quarter-turn — less travel — and cycle again. The door should just kiss the concrete, never load against it.

Just kiss the floor — no load

Prove it with the box test

Place a cardboard box in the door's path and press the button: the door must reverse on contact. That's the auto-reverse proving you haven't cranked the force past safe.

The UL 325 contact test — passed

Grinding, straining, or three rounds with no change? The cause is mechanical — springs, track or a worn limit assembly. Stop adjusting and describe what you saw in the quote form below; a stocked truck carries all three fixes.

Security Note

A Door That Won't Stay Closed Is a Door You Can't Lock

A garage door that reverses when closing is a nuisance at noon — at midnight, it's a security issue.

If it won't hold closed tonight, don't trust it. An inch of gap defeats the lock; a foot of gap is an invitation. Lock the man-door between garage and house, take the valuables in — and don't rely on the opener to hold the door. The auto-reverse that popped it open all day will do it again at 3 a.m.

What looks like a garage door that opens by itself after closing is usually drift — but at three in the morning it's indistinguishable from someone forcing it. Crews run 24/7 across the GTA; send a few details and a dispatcher names the likely branch in 3–5 minutes.
