    In short

    • The sensors lined up or replaced as a pair, the wiring checked, the door’s reverse tested.
    • The door won’t close while the beam between the two sensors is broken.
    • A blinking light usually means one sensor was nudged out of line, or its lens is dirty.

    What a sensor visit looks like

    Four steps, the same as every repair. The safety test is part of the job, not an extra.

    Two small sensors that watch the doorway as it closes

    One sensor sends a beam across the doorway and the other catches it. Break the beam or knock one out of line, and the door won’t close.

    The opener is the motor. It only steers a door the springs already balance.

    How the price works

    Sensors are tested before they are priced: lined up, cleaned or replaced, whichever the test shows.

    Before anything startsThe price is on the written estimate you approve before any work starts, and the invoice matches the number you approved.
    The sensor testEach sensor’s test goes on the estimate with a photograph, and you approve what is replaced.
    When you payMost standard repairs are paid after completion. A deposit may be required for special-order products or larger projects and will be shown in the written estimate before you approve the work.

    Sensor questions, answered

    The short version first. The technician explains the rest at the door.

    The sensor light is blinking. What does it mean?

    That is the two sensors near the floor. Usually one has been nudged out of line, or its lens is dirty.

    Can you replace just the sensors?

    Yes. The sensors come as a pair, and a pair can be replaced without touching the rest of the opener. The technician checks the wiring and tests the door’s reverse after.

    Is it the opener or the door?

    It can be either. If the motor runs and nothing moves, a spring may be broken, the opener may have let go of the door, or the door may be jammed. The technician starts with the door.

    Why can’t you give me a price on the phone?

    Because nobody has seen your door yet. The same symptom can come from different parts, so a technician looks before anything is priced.

    What does the warranty cover?

    Five years on parts and labor, every repair and every install. The scope is on your estimate and on the invoice.
