## Summary

- **Typical national range:** $85–$165 installed (parts plus labour)
- **Emergency / after hours:** $120–$235
- **Time on site:** 0.4–1 hours
- **Scales with door size:** no
- **Expected life:** 10+ years; misalignment is far more common than failure

A door that starts down and immediately reverses is nearly always the photo-eye safety sensors, and this is the repair most likely to need no parts at all.

## Why it fails

Two sensors face each other across the bottom of the opening. If the beam between them breaks, the opener refuses to close. They drift out of alignment when knocked, their lenses collect dust and cobwebs, and sunlight at certain angles can wash out the receiver. Actual sensor failure is the least common cause.

## What you are paying for

Very often just realignment or a dirty lens, which a tech may do inside the service call. Ask before booking — this is the repair most likely to need no parts at all.

## Signs you need this

- The door starts closing then reverses and the opener light blinks
- One sensor LED is off, flickering, or a different colour to the other
- It only happens at certain times of day, which points to sunlight
- Something is stored near the door blocking the beam

## Can you do it yourself?

**Worth trying yourself.** Genuinely worth trying yourself first. Wipe both lenses with a soft cloth, clear anything stored near the opening, and check both LEDs are steady. If one is out, loosen its bracket wing nut and move it slightly until both light steadily. This solves it more often than not, at no cost.

## Common questions

### Can I just disable the sensors?

No. They are the mechanism that stops the door closing on a child or a pet, they are federally required on every opener made since 1993, and bypassing them is both unsafe and likely to void insurance. A door that will not close is telling you something.

### Why does it only happen on sunny afternoons?

Direct sun on the receiving sensor washes out the beam. Repositioning the sensor, adding a small shade, or swapping which side transmits usually fixes it permanently.
