Door starts down, then reverses
The sensor path is one check. Track resistance, a crooked door, floor contact, travel settings, or another opener input can create a similar symptom.
Garage Door Sensor Repair in Northern NJ
Blinking indicators and closing reversals can involve an obstruction, alignment, wiring, power, compatibility, or another door problem. We diagnose the cause before recommending parts.
Indicator blinks or goes dark
The meaning depends on the opener model. We identify the equipment, inspect mounting and visible wiring, and follow its diagnostic information.
Intermittent closing problem
Loose brackets, wiring faults, moisture, direct light, vibration, or a failing component can make the symptom change during the day.
What sensor service can include
- Opener model and sensor compatibility check.
- Sensor position, brackets, lenses, and line-of-sight inspection.
- Visible low-voltage wiring and opener-terminal inspection.
- Door travel and resistance check so the sensor is not blamed for a mechanical problem.
- Repair or compatible replacement options.
- Safety reversal testing from the exact opener instructions.
Do not bypass a safety device or increase force to make the door close. Leave the opener off if the door is crooked, off track, or moving unpredictably.
Entrapment protection matters
CPSC says automatic residential garage door openers manufactured for sale on or after January 1, 1993 must meet additional entrapment-protection requirements. The permitted systems are more specific than a blanket claim that every opener has the same photo eyes. Follow the exact opener instructions and stop using an opener that fails its required reversal test.
