McCabe Electric Gate Sensor Adjustment | Jamul, CA | Fence & Gate Repair

High ambient temperatures, common near Alpine or the Collins Valley area, can cause metal gate components to expand. This expansion throws off the alignment of magnetic or contact sensors, preventing the gate from locking fully. Additionally, warped wood fence sections can obstruct the gate's latch or trigger false sensor reads. We adjust the sensor gap (typically 1–2 mm) and check for any fence warping nearby to restore proper lock function.

Common signs include: the gate starts reversing before it fully closes, you hear a clicking sound but the gate stops, or the gate opens partially and stops. If you notice any of these near the Lyons Valley area, it's a good idea to have us inspect the sensor alignment and check for warped fence boards that might be blocking the communication path between the transmitter and receiver.

Yes, absolutely. In Jamul, intense sun and dry conditions often warp wood fence panels. If a warped panel shifts enough, it can physically block the gate's swing path or reflect sunlight directly into the sensor, confusing it. Our weatherproofing service seals the wood to reduce moisture loss and warping. Combined with sensor recalibration, this can solve many intermittent lock failures.
