If your garage door won’t close with the remote, the batteries are likely dead. Once you activate the garage door opener, the trolley will latch back onto the chain and work properly. Pull the rope toward the door to take the trolley latch out of bypass mode. If your garage door is moving freely by hand, the trolley might be in bypass mode. The rope engages and disengages the door from the chain-driven by the garage door opener.
You can identify this part as it usually has a rope hanging from it. The mechanism that connects the garage door to the opener is called the trolley. Several stuck rollers can trick a garage door opening into thinking the door is hitting something. This is a good time to check the rollers and grease them with white lithium or silicone-based grease. If you find a damaged section, you can often bend it back to position with clamps or carefully-placed hammer strikes.īe sure to check the overhead track coming from the garage door opener as well. Inspect both tracks to ensure there aren’t any signs of damage. If your sensors are functional but the garage door still won’t close past a certain point, check the tracks to ensure there aren’t any obstructions blocking progress.Ī bent track or damaged roller can have the same effect. Simply loosen one of the sensors, adjust it until the small light stays steady, and tighten in place. If the sensors themselves are blinking, they might need aligning, as they need to “see” each other clearly.
