🔍 Why This Happens
Root cause analysis for your garage door opener's reversing mid-cycle
The safety sensor kit in your garage door opener has degraded or accumulated residue that prevents accurate readings. Sensors work by detecting a physical change (temperature, flame, position) — when they're coated in carbon, mineral scale, or corrosion, they send false signals or no signal at all. Cleaning the sensor often restores function temporarily, but replacement is the reliable fix.

🛡️ Prevention Tips
How to prevent your garage door opener's reversing mid-cycle from happening again after this repair.
Lubricate the chain, rollers, and hinges every 6 months with garage door lubricant (not WD-40).
Test the safety sensors monthly by placing an object in the door's path — the door should reverse immediately.
Don't disengage the emergency release unless necessary, and never pull it while the door is open.
Check torsion springs for signs of wear or rust annually. Springs have a finite cycle life and fail without warning.
When replacing a sensor, avoid touching the sensing element with bare hands. Oils from your skin can coat the sensor and cause false readings.
