Moisture-Corroded LiftMaster Board and an Undersized Solar Array
0:14Filmed on the job by Shield Gate Repair
What this video shows
A solar LiftMaster on a rural double farm gate that had been getting slower for months before it stopped. Water ingress had corroded the control board, and testing the power side showed the solar array had never been sized for the gate — so the batteries had been running permanently undercharged, stressing the electronics that failed. Board replaced, enclosure resealed, array resized to the actual load.
