What Causes the Door to Reverse Immediately?
Your opener is designed to reverse direction if it senses resistance or a safety hazard. When the door opens halfway and then closes, the opener is reacting to one of four things: sensor misalignment, incorrect travel limits, binding hardware, or a failing opener logic board. Our technicians isolate the cause with multi-point diagnostics used in opener repair service calls.
DIY Checks You Can Try First
- Clean the safety sensors: Dust or spider webs can break the infrared beam. Wipe both lenses gently.
- Realign the sensors: Ensure the LEDs on both sensors are solid. If one blinks, gently bend the bracket until it stays lit.
- Inspect the tracks: Remove objects, ice, or debris that could hit the rollers as the door opens.
- Lubricate rollers: Dry rollers create drag that triggers the opener to reverse. Use a silicone-based spray.
- Reset the opener: Unplug for 30 seconds and plug back in to clear temporary faults.
Professional Repairs We Perform
• Force & Limit Calibration
We adjust the up/down travel limits and force sensitivity so the opener knows exactly when to stop without reversing.
• Sensor Replacement
Sun-faded or water-damaged sensors send false signals. We install new, UL-compliant sensors and run alignment tests.
• Hardware & Balance Corrections
Binding rollers, bent tracks, or weak springs create resistance. We pair this service with roller and track tune-ups or spring repairs if needed.

Frequently Asked Questions
My opener light flashes when the door reverses. What does that mean?
Most openers flash the light to indicate a sensor or obstruction issue. Count the flashes and reference your manual; we can decode the flash pattern for you over the phone.
Could a new LED bulb cause the reversal?
Yes. Cheap LED bulbs emit radio frequency interference that confuses the opener receiver. We install opener-safe bulbs or relocate the antenna to fix the issue.
Should I increase the force setting to stop the reversal?
Only slightly. Over-tightening the force setting is dangerous and can prevent the opener from reversing when it should. It's better to correct the root cause of resistance.
Can an opener be too old to fix?
Openers older than 20 years may lack replacement parts and modern safety features. If repairs are extensive, we a new opener from our installation team.
What if the door hits the floor and then opens immediately?
That usually indicates the down-limit is set too far, so the door hits the floor and the opener thinks it hit an obstacle. We adjust the limit and ensure the weather seal compresses just enough.
