Garage Doors decision guide

Reviewed and updated September 24, 2026

How should garage-door photo eyes be checked safely?

Photo eyes must remain part of the door’s protection system; do not bypass them to obtain a closing cycle. For an otherwise sound door, begin with the exact opener manual. Amarr’s maintenance guidance describes checking for an ordinary obstruction and alignment problems, then using the specified safety test.

Use the exact opener manual to document the sensor indicators and specified safety-test result, then give that record to manufacturer support or a qualified garage-door technician.

Safe boundary for garage-door photo-eye alignment and safe testingKeep the travel path clear and use only the photo-eye checks and safety test stated in the exact opener manual.

Which situation best matches the home?

01

Confirm that a homeowner-safe check is appropriate

Use this process only when the door is otherwise sound and the opener manual identifies a homeowner test. If the door moves unpredictably, has visible damage, or involves springs, cables, supports, or other high-tension hardware, stop operation and request qualified service. Keep people, pets, and vehicles out of the travel path. Do not defeat, cover, disconnect, or electrically bypass the photo eyes to make the door close.

02

Follow the exact model rather than a generic light code

Record the opener and sensor model, the indicator state, and whether an ordinary visible obstruction is present. Compare those observations with the manufacturer’s current manual for that exact system. Indicator colors, blink patterns, alignment details, and adjustment steps can differ. Do not import a color meaning or procedure from another brand’s example. Amarr’s guidance supports checking obstruction and alignment; it does not define every opener’s indicators.

03

Separate observation, test, and repair

If the exact manual provides a safe alignment observation and protection test, follow only that documented sequence and stop if the result differs from the manual. Record the result without repeating a failed closing cycle. A failed test does not identify the failed component. Leave wiring, mounting changes, opener settings, and mechanical door work to the appropriate professional, and keep the system out of automatic operation until protection is restored.

Notice next: Use the exact opener manual to document the sensor indicators and specified safety-test result, then give that record to manufacturer support or a qualified garage-door technician.

These records narrow the request; they do not prove compatibility, performance or a failed part.

What to record
  1. Use this process only when the door is otherwise sound and the opener manual identifies a homeowner test. If the door moves unpredictably, has visible damage, or involves springs, cables, supports, or other high-tension hardware, stop operation and request qualified service.
  2. Record the opener and sensor model, the indicator state, and whether an ordinary visible obstruction is present. Compare those observations with the manufacturer’s current manual for that exact system.
  3. If the exact manual provides a safe alignment observation and protection test, follow only that documented sequence and stop if the result differs from the manual. Record the result without repeating a failed closing cycle.
  4. Use the exact opener manual to document the sensor indicators and specified safety-test result, then give that record to manufacturer support or a qualified garage-door technician.
Stop and get appropriate help
  • Do not cover, disconnect, bypass or electrically alter the photo eyes to obtain a closing cycle.
  • Stop operation and request qualified service when the door is damaged, unpredictable or involves springs, cables or supports.

Short answers

Questions people ask before the call

Can I bypass a photo eye to make the door close?

No. Photo eyes remain part of the protection system and must not be covered, disconnected or electrically bypassed.

Should I align the sensors from a generic diagram?

Use the exact opener manual and its specified indicator and safety-test sequence instead of a similar product’s diagram.

When should I stop homeowner checks?

Stop when the door is damaged, unpredictable or the question involves springs, cables, supports or other high-tension hardware.
