**The catch at a repeatable height, and the fact that pulling helps, suggest mechanical binding.** Rain could change the clearance around a wooden door or jamb, or make a rubbing weather seal more troublesome. That is a working hypothesis; a safety-sensor fault can also cause reversal.

Start with these checks:

1. **Test the door by hand when wet.** With the door fully closed, unplug the opener and disengage it according to its manual. Slowly raise and lower the door using its handle, keeping fingers clear of panel joints. Feel for resistance around the troublesome height. Disengaging an open door can let it fall if its springs are faulty. Stop if it is unusually heavy or difficult to control.

2. **Locate the rubbing point.** Look for fresh scrape marks on the door edges and jambs, tight side weatherstripping, and swollen or warped wood. Watch for a roller that stops turning or catches at a track joint. Check the entire mechanism at that door position: the troublesome roller may be well above the floor.

3. **Clean and lubricate appropriately.** Remove debris from the tracks and wipe them clean. Follow the door manual for lubricating hinge pivots and serviceable roller bearings; keep grease off the track’s rolling surfaces.

4. **Check balance and sensors.** A manually operated door should move smoothly and remain approximately halfway open. If it pulls strongly upward or drops, have a technician check the balance. If manual travel is smooth, clean and dry the photo-eye lenses, check their alignment indicators during closing, and consult the opener’s diagnostic codes.

**Do not increase closing force to overcome the catch or keep assisting the powered door by hand.** Excess force can compromise the reversal protection. Leave spring, cable, and bottom-bracket adjustments to a garage-door technician. After repairs, perform the safety tests specified in your opener’s manual.
