Why Does My LiftMaster Garage Door Reverse Before Closing Completely?

Device: LiftMaster Garage Door Opener (8550W, 8550WLB, 8365W, 87504, 84505R)

Your LiftMaster garage door opener starts to close then reverses direction and reopens before reaching the fully closed position. This happens every time you attempt to close the door and the opener light may flash to indicate a fault. The reversal is caused by the safety reversal system detecting an obstruction in the door path, misaligned photo-eye sensors, or incorrect close-limit and force settings on the opener.

Why Is My LiftMaster Safety Sensor Showing One Yellow and One Green Light?

Device: LiftMaster Garage Door Opener (LiftMaster 8500W, 8550W, 8355W, 8360W, 87504, 84501)

Your LiftMaster garage door safety sensors show one amber or yellow LED and one green LED. The amber yellow light is on the sending sensor which emits the infrared beam. The green light is on the receiving sensor which detects the beam. A solid amber and solid green means normal operation. If the green light is blinking or off the sensors are misaligned and the door will not close. The opener light may flash 4 times indicating sensor misalignment.

Why Is My LiftMaster 8500W Wall Mount Opener Unresponsive After a Power Surge?

Device: LiftMaster 8500W Elite Series Wall Mount Opener (LiftMaster 8500W, 8500WLB, Elite Series Wall Mount)

Your LiftMaster 8500W wall mount garage door opener is completely unresponsive after a power surge or power outage. The opener does not respond to the wall button, remote controls, or the myQ app and shows no status lights. Power surges can trip the internal safety fuse on the 8500W logic board or cause a fault state that requires a specific reset procedure to clear.

Why Won't My LiftMaster myQ Smart Garage Hub Connect to the App?

Device: LiftMaster myQ Smart Garage Hub (MYQ-G0401, MYQ-G0301, WLED, 890MAX)

Your LiftMaster myQ Smart Garage Hub will not complete the WiFi setup in the myQ app. The hub may fail during the connection steps, show as offline after initial setup, or work briefly then stop connecting. The myQ hub only supports 2.4GHz WiFi and requires a stable connection since it is typically mounted in a garage where WiFi signal is weaker than in the main living area of the home.

Device: LiftMaster myQ Home Bridge (LiftMaster myQ Home Bridge, WRGDS, MYQ-G0303)

Your LiftMaster myQ Home Bridge repeatedly loses its HomeKit connection, causing the garage door to show as No Response in the Apple Home app. You must regularly remove and re-add the bridge from HomeKit to restore control. The myQ Home Bridge uses HomeKit over WiFi and loses its pairing when the bridge IP address changes or when the HomeKit pairing record becomes corrupted on the bridge firmware.

Why Does My LiftMaster MyQ Show Obstruction When the Door Path Is Clear

Device: LiftMaster MyQ Garage Door Opener (84501, 87504, 8500W, 8550WLB)

Your LiftMaster myQ app reports obstruction and blocks remote closing even though the garage doorway is clear. The door may close from wall control but fail from app for safety reasons. This is typically caused by sensor misalignment, sunlight interference, dirty lenses, wiring voltage drops, or travel force settings triggering false safety checks.
