The LiftMaster K74-36806-5 is a metal solar control box replacement for select LA412 series swing gate operator systems. In a solar actuator installation, the control box is more than a cabinet: it keeps the control board, batteries, charge wiring, accessory wiring, and solar input connections protected from weather and physical damage. A damaged solar box can create intermittent low-battery faults, corrosion on terminals, and unreliable gate movement.
This part should be used only on LA412 series solar configurations that call for the metal solar control box. It should not be treated as the same part as K74-36806-4 for LA500U or as a generic metal cabinet. Solar systems are especially sensitive to battery condition, wiring polarity, charging performance, and water intrusion, so replacing the enclosure is a good time to inspect the entire low-voltage control area.
Use with select LiftMaster LA412 series solar swing gate operator applications requiring the K74-36806-5 metal solar control box.

When replacing a solar control box, do not just move corroded components into the new enclosure. Check battery age, battery terminals, solar panel voltage at the controller, water entry points, and wire strain reliefs.
Control box and E-box replacement involves operator power, batteries, wiring, and safety-device connections. Installation and electrical troubleshooting should be performed by a qualified gate technician, especially on commercial operators, high-voltage systems, or any gate that moves unexpectedly. Do not bypass monitored entrapment protection or required safety devices.
It is listed for various LiftMaster LA412 series swing gate operators using solar applications.
No. K74-36806-4 is associated with LA500U metal control box applications, while K74-36806-5 is the LA412 solar metal control box.
Treat it as the control box replacement kit only unless the active product listing specifically states that solar panels, batteries, or electronics are included.
The internal layout, battery area, charging wiring, and accessory routing can differ from non-solar control boxes.
Battery voltage, solar charging, board operation, limit setup, accessories, remotes, and all required monitored safety devices should be tested.
