Signs Your Sensors or Controls Need Attention
Door Won't Close
Safety sensors detect an obstruction. Most common reason doors fail to close.
Sensor Light Blinking
Red or amber blinking light indicates misalignment or dirt on sensor lenses.
Door Reverses Unexpectedly
Door closes then reverses. Usually sensor detecting false obstruction.
Wall Button Not Working
Button clicks but door doesn't respond. May need replacement or rewiring.
Keypad Unresponsive
Can't enter code or door doesn't open from keypad. Battery or electronics issue.
Remote Issues
Handheld remote not working. May be receiver module or remote battery.

Understanding Your Door's Safety System
How Safety Sensors Work
Every modern garage door opener has safety sensors installed on both sides of the door opening at a few inches above the ground. These "photo eyes" work like an invisible beam across the bottom of your door. If anything blocks this beam while the door is closing, the door reverses immediately.
This is a critical safety feature mandated by federal safety standards. Sensors prevent the door from crushing people or objects in its path.
Sending Sensor (Usually Left)
Emits an infrared beam across the door opening to the receiving sensor.
- • Usually has a steady light
- • May have lens contamination first
- • Aligned with receiving sensor
Receiving Sensor (Usually Right)
Receives the infrared beam and communicates with the opener.
- • Blinking light shows it's receiving signal
- • Misalignment is common cause of failure
- • More likely to fail if hit or disturbed
What the Blinking Light Means
Steady Light: Sensor is receiving signal. Door should close normally.
Blinking Light: Signal interrupted. Usually due to misalignment, dirt, or broken lens.
No Light: Sensor not powered. Check power and wiring.
Wall Buttons, Keypads & Remote Controls
Wall-Mounted Push Buttons
The simplest way to operate your garage door from inside. A hardwired button mounted on your garage wall.
- Single Button: Up/down toggle. Press once to open, again to close.
- Multi-Button Panels: Separate open and close buttons, emergency stop, or multiple door controls.
- Illuminated Options: Buttons with lights for nighttime visibility.
Common Issues: Stuck button, intermittent contact, broken mounting.
Wireless Keypads
Battery-powered keypads allow you to open your door from outside without a remote control. No wiring needed.
- Programmable Codes: Set 4-digit codes that family members use.
- Backlit Buttons: Easy to see at night.
- Weather Resistant: Designed for outdoor mounting.
Common Issues: Dead battery, worn buttons, code forgotten, receiver not responding.
Remote Controls & Smart Features
Traditional handheld remotes and newer smart home connectivity options.
- Handheld Remotes: Classic 1, 2, or 3-button remotes for car or pocket.
- Smart Openers: WiFi-enabled openers that work with smartphone apps.
- Voice Control: Works with Alexa, Google Home, and other smart home systems.
Common Issues: Low battery, receiver module failure, signal interference, app connectivity.
Our Service Process
Diagnostic Assessment
We test your sensors, buttons, and keypads to identify exactly what's wrong. We don't replace parts you don't need.

Explanation & Education
We explain what was wrong, what we fixed, and how to prevent future problems.
Frequently Asked Questions
How much does sensor repair cost?
Sensor cleaning and alignment is usually $75-150. Replacement sensors run $150-300 depending on the brand. We always provide a quote before doing any work.
Can I clean the sensors myself?
You can gently clean sensor lenses with a soft cloth, but alignment and diagnostics require professional tools. If cleaning doesn't fix it, call us.
Why does my door close then reverse?
Usually misaligned or dirty sensors. The door closes, then the sensor detects something (or thinks it does) and reverses. Professional alignment fixes this.
Do you work with all opener brands?
Yes! We service LiftMaster, Chamberlain, Genie, Craftsman, Wayne-Dalton, Linear, and all other major brands. Sensors are pretty universal.
How long until my door works again?
Most sensor repairs take 30-60 minutes. We often complete the work during your appointment. Emergency closures due to sensor failure often resolved same-day.
