FIXED ON THE PHONE
Problems We Solve Before We Ever Drive Out
Not every garage door problem needs a technician. A large share of the calls we take are solved in a few minutes on the phone at no charge — and we would rather do that than charge you for a trip. These are real call types from around Canton and North Metro Atlanta, written the way the conversation actually goes. We describe callers by area only; we never publish customer names.
Remotes dead, wall button fine — lock mode was on
Two remotes and the outside keypad stopped working the same day. The wall button still opened the door.
CALLER
Both remotes quit at the same time. Two new batteries didn't help. Do I need a new opener?
HG DISPATCHER
Probably not. If the wall button works, the motor and the door are fine. Look at the wall console — is any light on it blinking?
CALLER
Yes, there's a small light flashing next to a padlock symbol.
HG DISPATCHER
That's lock mode. It disables every remote so nobody outside can open the door. Hold that padlock button for about two seconds until the blinking stops, then try a remote.
CALLER
It stopped blinking… and the remote just worked. My son must have leaned on it.
Door reverses every time — a cobweb across the sensor
The door closed about a foot, reversed, and the opener lights flashed ten times.
CALLER
It goes down a foot then goes right back up, and the lights blink at me.
HG DISPATCHER
That's the safety sensors refusing to let it close. There are two small eyes near the floor on each side. Are both little lights steady, or is one blinking?
CALLER
The left one is steady, the right one is flickering.
HG DISPATCHER
Wipe the lens on the flickering one with a dry cloth, and check for a cobweb between them — that's enough to break the beam.
CALLER
There was a web right across it. Cleaned it off and the light went solid. Door closed on the first try.
Opener completely dead — a tripped outlet behind the motor
No lights, no sound, nothing from the wall button, remotes or keypad.
CALLER
It's totally dead. No light, no noise. I checked the breaker and it's on.
HG DISPATCHER
Before we come out — can you reach the outlet the opener is plugged into on the ceiling? Is there a small reset button on it?
CALLER
Hang on. Yes, it's one of those with two buttons. The reset one is popped out.
HG DISPATCHER
Press it in firmly. Those GFCI outlets trip during storms and after a freezer or compressor kicks on the same circuit.
CALLER
Lights just came on. That's embarrassing — and it rained hard last night.
Motor runs, door doesn't move — trolley never re-engaged
The opener hummed and the chain moved, but the door stayed shut.
CALLER
The motor runs and I can see the chain moving, but the door doesn't budge.
HG DISPATCHER
Sounds like the door is disconnected from the opener. Did anyone pull the red rope hanging from the rail — maybe during the outage last week?
CALLER
I did, to get my car out.
HG DISPATCHER
That releases the trolley. Make sure the door is all the way down, then press the wall button once — it should re-latch when the trolley slides past the carriage. Listen for a click.
CALLER
Clicked, and now it opens normally. So nothing's broken.
Remote range shrank to three feet — a new LED bulb
The remote only worked directly under the opener; it used to work from the street.
CALLER
I have to be right under the motor for the remote to do anything. New batteries didn't change it.
HG DISPATCHER
Did you replace the light bulb in the opener recently?
CALLER
Yes, a bright LED one about a month ago.
HG DISPATCHER
That's the cause more often than anything else. Many LED bulbs put out radio noise on the same frequency as your remote. Try running the door with that bulb removed.
CALLER
Took the bulb out and the remote works from the mailbox again.
Keypad stopped working — a nine-volt battery
Keys lit up but the door never responded from the outside keypad.
CALLER
The keypad lights up when I press it but the door ignores me. The remotes are fine.
HG DISPATCHER
The keys light on very little power, but transmitting takes more. When did you last change the nine-volt battery in it?
CALLER
Never, and we've been here six years.
HG DISPATCHER
That's it. Slide the cover off, swap in a fresh nine-volt, and clean off any white powder on the contacts. If the code doesn't work after that, call back and I'll walk you through re-entering it.
CALLER
New battery in, code worked first try.
Door won't lift on a cold morning — seal frozen to the slab
The opener strained, clicked and gave up after a night in the low twenties.
CALLER
It tries to lift, groans, then stops. First really cold morning of the year.
HG DISPATCHER
Don't keep pressing the button — you'll strip the gear. Go outside and look at the bottom rubber where it meets the concrete. Is there ice along it?
CALLER
There's a frozen line all the way across.
HG DISPATCHER
The seal is stuck to the slab. Break the ice bond along the bottom with warm water or a plastic scraper, then try once. Don't force it.
CALLER
Broke it loose and it opened right up.
Door stops after a few inches — the manual slide lock
The door lifted a few inches, jerked and stopped. The caller feared a broken spring.
CALLER
It moves maybe four inches and stops. I read that means a broken spring.
HG DISPATCHER
Often it does. Look at the spring on the shaft above the door — is there a two-inch gap in the coil?
CALLER
No, it looks like one continuous spring.
HG DISPATCHER
Good. Then check the side of the door about waist height for a metal slide bar going into the track — some doors have a manual lock.
CALLER
It's slid into the track. I have no idea when that happened. Pulled it back and the door works.
Door only misbehaves in the late afternoon — sun on the sensor
Perfect operation all day, then refused to close between about 5 and 7 p.m.
CALLER
It's fine every morning, but in the evening it won't close. Nothing's in the way.
HG DISPATCHER
Does your driveway face west?
CALLER
It does.
HG DISPATCHER
Low sun shining straight into the receiving sensor can wash out the beam. Try shading that sensor with your hand this evening and see if the door closes.
CALLER
Shaded it and the door closed immediately. So it's the sun, not the opener.
Constant beeping in the garage — a spent backup battery
A repeating chirp from the opener with normal door operation.
CALLER
Something in the garage beeps every 30 seconds. The door works fine.
HG DISPATCHER
Does your opener have a battery backup — a small panel on the side of the motor head?
CALLER
There is one, with a red light on it.
HG DISPATCHER
That's the backup battery telling you it's done. They last three to five years. The door will keep working; you just lose outage operation until it's swapped.
CALLER
Good to know — I thought the opener was failing.
Door closes by itself — timer-to-close was enabled
The door closed on its own a few minutes after being opened.
CALLER
It closes by itself. Is somebody else's remote opening my door?
HG DISPATCHER
Very unlikely with a rolling-code opener. Does it close after roughly the same amount of time every time — five or ten minutes?
CALLER
Now that you say it, about five minutes.
HG DISPATCHER
That's timer-to-close. It's a feature, usually turned on through the app or the wall console. Warning lights and a beep run before it moves.
CALLER
My wife turned it on in the app last week. Mystery solved.
Loading dock door dead at 7 a.m. — operator left in lockout
A rolling steel dock door would not respond to any control station before a delivery.
CALLER
Dock door is dead and we have a truck at eight. Neither control station does anything.
HG DISPATCHER
Check the disconnect switch or key switch near the operator first — is it in the off or locked position?
CALLER
There's a key switch turned sideways. Night crew must have set it.
HG DISPATCHER
Turn it back, then press open from the inside station. If it hums without moving, call me straight back — that would point to a fuse.
CALLER
It opened. We're loading on time.
When it isn't a phone fix
Some symptoms mean the door itself is unsafe to operate, and no phone advice replaces a technician. Stop using the door and call us if you see any of these:
- A two-inch gap in the spring above the door, or a loud bang from the garage.
- One side of the door sitting higher than the other.
- A cable hanging loose or unwound off its drum.
- A door partly off its track, or a bent track section.
- A door that will not stay put at waist height when released by hand.
