Door moves a few inches then stops; multiple beeps; E18 displayed

Safety first: Clear the area around the door and ensure the door is in good mechanical condition before running calibration.

• Inspect door hardware: Confirm springs, cables, and rollers are intact and the door moves smoothly by hand.
• Reset opener: Perform a factory reset on the Skylink opener (refer to manual; often involves holding SET/LEARN for an extended period).
• Run auto‑set: Initiate the force/travel auto‑set procedure as described by Skylink. Typically, the opener will run the door fully open and closed to learn force limits.
• Monitor for obstructions: Ensure nothing contacts the door during this process. If E18 recurs, inspect the encoder and limit switches for proper operation.
• Service door if needed: If the opener cannot complete calibration due to a heavy or binding door, have a professional adjust or repair the door before attempting again.
