QUICK ANSWER
If the door starts down and goes back up, check the safety sensors first. Wipe the lenses and make sure nothing blocks the beam. If that does not fix it, the tracks, rollers, or opener settings need service.
A door that will not close is a security problem. The good news is that the cause is often simple.
Common causes
Blocked or misaligned safety sensors are the top cause. Next are bent tracks, worn rollers, or opener limit settings that need adjusting through opener repair.

What can cause the problem?
Interrupted safety sensing
An obstruction, bracket movement, or sensor fault can affect closing. A blinking indicator should be interpreted for the opener model.
Resistance along the travel path
Track damage, panel movement, or other mechanical resistance may cause a stop or reversal. That needs a different repair from a sensor issue.

Can I hold the button to force it shut?
Do not override or work around a safety problem to keep operating a damaged door. Describe the issue to Royalty and discuss the next available visit, especially if the property is unsecured.
Does reversal always mean bad sensors?
No. Door resistance and travel-related problems can also be involved. Note where reversal happens and any warning lights; the combined observations help guide an inspection.
