Steps

Goal: Confirm the symptom, rule out power and remote issues, then isolate the cause—rain sensor, obstruction, or motor.

  • Press the remote or wall switch.
  • Good: The skylight stays closed when it should open—proceed to Check power and remote.
  • Bad: The skylight opens—no fix needed; monitor if it was intermittent.

Check power and remote

Goal: Rule out dead remote battery and power loss to the motor.

  • Replace the remote battery per the manufacturer instructions. Confirm the remote is paired to the motor (see owner manual for pairing).
  • Verify the motor has power—check the circuit breaker and the motor unit indicator lights. Reset the breaker if tripped.
  • Test the wall switch or wired control if present. If the remote works but the wall switch does not, the switch or its wiring may be faulty.
  • Good: Fresh battery and power on. Test the skylight—it should open when commanded.
  • Bad: Still no response—proceed to Rain sensor and obstructions.

Rain sensor and obstructions

Goal: Check the rain sensor and look for blockages without going on the roof.

  • Unplug the motor unit for 30 seconds, then plug it back in. This power-cycle resets many units.
  • Check the rain sensor. If it is wet, dirty, or faulty, it may block opening. Clean and dry it per the manual; bypass or test per manufacturer instructions.
  • From inside, look for debris, leaves, or ice visible around the skylight frame. Do not climb on the roof—roof work requires a professional.
  • Good: Rain sensor dry, motor reset. Test the skylight.
  • Bad: Still no response—proceed to motor test.

Motor test

Goal: Determine if the motor runs and whether the fault is internal.

  • Press the remote or wall switch and listen at the motor unit (usually in the attic). You should hear a hum or whir.
  • Motor runs but skylight does not move: Drive, gear, or limit switch failure. Call a skylight or roofing professional.
  • Motor does not run: Check power again (breaker, motor unit). If power is confirmed and the motor still does not run, the motor has failed—call a technician.
  • Check for blinking error codes on the motor unit. Match the pattern to the owner manual and address the indicated cause.

When to get help

Call a skylight or roofing professional if:

  • The motor runs but the skylight does not move (drive, gear, or limit switch failure).
  • You need to clear debris or ice from the roof (roof work is dangerous—do not climb without training and fall protection).
  • You have tried all steps and the skylight still does not work.
  • You are not comfortable with electrical repair.

Verification

  • The skylight opens when you press the remote or wall switch.
  • No grinding, clicking, or stuck movement.
  • The motor unit shows no error codes.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify the skylight does not open when you press the remote or wall switch.
  2. Power and remote Replace remote battery; check circuit breaker and motor unit power.
  3. Power-cycle and rain sensor Unplug motor for 30 seconds; check rain sensor bypass or test.
  4. Obstructions Check for visible debris from inside; roof work requires a pro.
  5. Call a pro Motor runs but skylight does not move, roof work needed, or all steps tried with no fix—call a skylight or roofing professional.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Motor brand and model
  • Remote battery condition
  • Whether the motor unit has power
  • Whether rain sensor is wet or faulty
  • Error code pattern (if any)
  • Steps already tried

Does the skylight fail to open when you press the remote or wall switch?

Press the remote or wall switch. If nothing happens, the opener has failed.

Press the remote or wall switch. Good: skylight stays closed when it should open—proceed to power and remote checks. Bad: skylight opens—no problem; check if it was a one-time glitch.

Yes No

Skylight works

The skylight opens when commanded. No fix needed. If it was intermittent, monitor and retry the steps if it fails again.

Done

Is the remote battery fresh and does the motor have power?

Low remote battery or tripped breaker are common causes. Replace battery and check power.

Replace the remote battery per the manufacturer. Check the circuit breaker for the attic or room—reset if tripped. Confirm the motor unit has indicator lights. Good: fresh battery and power on—test the skylight. Bad: still no response—proceed to rain sensor and obstructions.

Yes No

You can change your answer later.

Does the skylight open after battery and power check?

Test the skylight with the remote or wall switch. If it opens, the fix is complete. If not, proceed to check rain sensor and obstructions.

Done

Is the rain sensor dry and has the motor been power-cycled?

Rain sensor or a glitched motor can block the skylight.

Unplug the motor for 30 seconds, then plug back in. Check the rain sensor—if wet or dirty, clean and dry it per the manual. Bypass or test per manufacturer instructions. Good: sensor dry, motor reset—test again. Bad: still no response—proceed to motor test.

Yes No

You can change your answer later.

Does the skylight open after rain sensor check?

Test the skylight. If it opens, the fix is complete. If not, proceed to motor test. Do not climb on the roof—call a pro for roof work.

Done

Does the motor run when you press the remote or wall switch?

Listen at the motor unit (usually in the attic) for a hum or whir.

Press the remote or wall switch and listen at the motor unit. Motor runs but skylight does not move: drive, gear, or limit switch failure—call a pro. Motor does not run: check power again or motor has failed—call a pro. Do not climb on the roof.

Yes No

Motor runs but skylight does not move

Drive, gear, or limit switch failure. Call a skylight or roofing professional. Do not attempt to repair or access the roof unless you are trained and have proper fall protection.

Done

Call a pro

Call a skylight or roofing professional if the motor does not run after power checks, if you need to clear roof debris or ice, if you have tried all steps and the skylight still does not work, or if you are not comfortable with electrical repair. Do not climb on the roof without proper training and fall protection.
