Motor humming but the door won't budge? Remote dead, wall button still works? Sensor blinking? Most opener problems trace to one of eight common faults — and most fix in under an hour. Garage Door Repair Genie techs handle belt, chain, screw-drive, and direct-drive openers across all major brands.
Most homeowners can rule out the simplest causes in 5 minutes. None of these involve the spring, cable, or opener gear — they're all safe.
If those didn't fix it, the issue is one of the deeper ones below — and a tech is the right call.
| Symptom | Most likely cause | Typical fix |
|---|---|---|
| Motor hums, door doesn't move | Stripped main drive gear (very common on 10+ year openers) | Gear replacement — not full opener replacement |
| Door closes 6 inches then reverses | Photo-eye sensor misaligned or blocked | Realign sensors so both LEDs are solid |
| Door starts and stops mid-travel | Force settings drifted or an obstruction | Adjust force limits, inspect tracks for debris |
| Wall button works, remote doesn't | Remote battery, broken remote, or programming lost | Replace battery or reprogram |
| Neither button works, opener has power | Logic board or wall switch failed | Board or switch replacement |
| Opener opens by itself randomly | Stuck remote button, RF interference, or worn limit switch | Find the stuck remote; if no remote, replace the receiver |
| Door slams the last 6 inches | Travel limit drifted, or springs are losing tension | Adjust limit; if springs are weak, address those too |
| Loud grinding from the motor head | Stripped gear or worn chain/belt | Gear or drive-component replacement |
A common upsell trap is being told you need a whole new opener when you actually just need a part replaced. The honest decision tree:
| Situation | Smart move |
|---|---|
| Stripped main drive gear, opener under 10 years old | Replace the gear ($80-$160). Keep the opener. |
| Logic board failure, opener under 10 years old | Replace the board if available; otherwise consider full replacement |
| Photo-eye sensor failure | Replace the sensors ($40-$80). Keep the opener. |
| Opener over 15 years old, multiple parts failing | Full replacement — new opener will be cheaper than three repairs over two years |
| Opener older than 1993 (no photo-eye sensors) | Full replacement — pre-1993 units don't meet current safety code |
| Want smartphone control, battery backup, or quiet belt drive | Replacement is the only path |
Reputable techs will tell you when a part repair makes sense vs. full replacement. If the answer is always "you need a new one," get a second opinion.
Local technicians are familiar with all major opener brands and most older units still in service:
If your opener is older than 15 years and the brand has been discontinued, parts may be the deciding factor on repair vs. replacement.

Opener trouble is annoying because it can look random. The remote fails, then the wall button works, then the door reverses like it changed its mind.
Before you assume the motor is dead, ask one question: does the door move smoothly by hand? If it doesn't, the opener may be the messenger, not the problem.
Most often the main drive gear has stripped — common on belt and chain drive openers around the 10-year mark. The motor still spins, but the gear that translates motion to the chain or belt is too worn to grip. Less commonly: a broken spring is making the door too heavy for the opener to lift, or the trolley has disengaged from the rail.
Probably not. Check the breaker, check the wall outlet (try plugging in a phone charger), check whether the wall lock button has been engaged, and check whether the manual release cord is hanging loose (someone may have pulled it). If those are fine, the wall switch or logic board is the next suspect — both are usually repairable, not a full opener replacement.
Average residential lifespan is 12 to 15 years. Belt drives last a bit longer than chain drives because the belt doesn't wear the gear as fast. Heavy use (primary entrance, multiple cars) shortens the lifespan; a vacation home opener can last 20+ years.
Worth it if you want phone control, vacation alerts, package delivery scheduling, or battery backup (required by code in some states for new installs). Not necessary if your existing opener works fine. Many existing openers can be retrofitted with smart-controller add-ons for $40 to $80, avoiding full replacement.
No. California requires it on new installs (SB 969); most other states don't. If you live somewhere with frequent outages or use the garage as your primary entrance, it's worth specifying when you buy a new opener — the upcharge is small.
