Door opens normally but will not close with remote; must hold wall button down to close.

Safety first: The hold-to-close behavior indicates the safety system is not satisfied. Do not bypass sensors for normal use.

Inspect sensors:

• Check that both Decko safety sensors are mounted at the same height (about 4–6 inches above the floor) and facing each other.
• Clean the lenses with a soft cloth.
• Adjust alignment until both sensor LEDs are solid (not blinking).

Check wiring:

• Verify that the wires are firmly connected at both the sensors and the opener head.
• Correct any reversed polarity if your model requires specific +/− connections.

Once the sensors are aligned and wiring is correct, the door should close normally without holding the button.
