AfterSensor Calibration in Tempe, AZ
Garage door sensor calibration in Tempe, AZ, typically costs between $85 and $150, depending on whether the issue stems from simple misalignment or degraded wiring caused by our local heat. We provide same-day service for these adjustments, and because we operate under The Haven Standard, we provide a written price and scope of work before we touch a single tool. If your garage door is reversing for no apparent reason or the safety lights on your sensors are blinking, call us at (602) 962-8352 to get a technician to your home.
At Servo Garage Doors Tempe, we understand that a garage door that refuses to close is more than a minor annoyance, it is a security risk for your home. We are independently owned and operated, led by Marcus Deller, and we follow a strict evidence-first policy. We do not guess at problems, and we do not perform “mystery” repairs. Every visit includes a documented photo record of what we found, ensuring you see exactly why your sensors were failing before we quote a fix. This approach is part of our commitment to transparency, and it applies to every Garage Door Repair in Tempe we perform.
When You Need Sensor Calibration
Your garage door sensors, technically known as photo-eyes, act as the primary safety mechanism for your system. They send an infrared beam across the opening of your garage. If that beam is broken, the motor receives a signal to stop and reverse the door. In Tempe, where the heat can cause metal tracks to expand and shift over time, we see sensor issues frequently and often recommend Track Realignment as part of the fix. Here are the common symptoms that indicate you need a professional calibration:
- The door reverses immediately: If the door starts to close and then stops or reverses while the pathway is clear, your sensors are likely misaligned or receiving a false signal.
- The motor lights are flashing: Most modern openers, such as those from LiftMaster or Craftsman, will flash the courtesy lights when the sensors detect a fault. This is the system telling you it cannot verify the safety of the door path.
- Sunlight interference: In some Tempe neighborhoods with west-facing driveways, the intense afternoon sun can hit the receiving sensor directly, “blinding” it and preventing the door from closing. We often install sun shields or adjust the angle to resolve this.
- Loose mounting brackets: The vibrations from daily use, combined with the extreme temperature fluctuations in the Arizona desert, can loosen the mounting brackets on the door frame. If the sensor is even slightly tilted, the infrared beam will miss its target.
- Wiring degradation: Older homes or those with previous amateur repairs often have exposed wiring that has become brittle due to heat. If the connection is intermittent, the door will behave erratically.
If you notice these signs, do not force the door to close by holding the wall button. This bypasses the safety feature and can be dangerous, especially if there are pets or children near the door. Call (602) 962-8352 and let us verify the alignment.
Our Sensor Calibration Process
We do not believe in “guessing” what is wrong. When we arrive at your home, we follow a specific sequence to identify the failure point. This is how we handle sensor calibration:
- Visual Inspection and Documentation: Per Clause 4 of The Haven Standard, we photograph the current state of your sensors and brackets. We show you the photos so you understand exactly why the system is failing.
- Beam Alignment Testing: We use a laser alignment tool to check if the sending and receiving eyes are perfectly parallel. Even a fraction of an inch of variance can cause the system to fail.
- Wiring and Connection Review: We inspect the wire runs from the motor to the sensors. We check for loose terminals, wire nuts that have corroded, or insulation that has dry-rotted from the heat.
- Written Price and Scope: Before we perform any adjustment or replacement, we provide a flat, written price. There are no hidden fees, and you know the cost before we start.
- Final Safety Test: After calibration, we perform a formal safety reversal test. We place an object in the path of the door to ensure it reverses correctly, and we provide you with a record of this completed work.
Whether you have a newer Raynor opener or an older unit, we have the parts and the experience to get it working again. If you need a home consultation regarding your garage door system, our team is ready to assist.

FAQs - Sensor Calibration
Why does my garage door only close when I hold the button down?
Your garage door is defaulting to manual mode because the safety sensors are failing to communicate, which is a standard safety feature in almost all modern openers. By holding the button, you are manually overriding the safety stop, which is dangerous because the door’s automatic reversal will not function. You need a technician to align or replace the sensors to restore automatic operation safely.
Can I fix misaligned sensors myself?
While you can visually check if the sensors are tilted, we strongly advise against attempting to splice wires or adjust internal motor settings yourself if you are not experienced with low-voltage electrical systems. Garage doors are heavy, under high tension-often requiring Spring Repair expertise-and the motor housing contains electrical components that can be damaged by improper handling. Our technicians carry the proper tools to align these safely and verify the signal strength, ensuring the repair lasts. Call (602) 962-8352 for a professional adjustment.
Do you service all brands of garage door sensors?
Yes, we service all major brands, including LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. The underlying technology for safety sensors is consistent across most manufacturers, and we stock common replacement parts for these brands on our trucks to minimize the need for return trips.
What does the “365-Day Done Right Promise” mean for my repair?
Our promise is simple: if the repair we performed is not right, we make it right. This is backed by our adherence to The Haven Standard, which dictates how we document our work and our pricing. We don’t rely on handshakes; we rely on a documented record of the service, the parts used, and the pricing agreed upon before the work began. If you have any concerns after our visit, simply call us, and we will address it.
If you are tired of dealing with a door that won’t close, we are ready to help. We provide honest, evidence-based service to homeowners throughout the area. Call (602) 962-8352 today for a free estimate or to schedule your service.
