It’s the call every property manager dreads: the main gate is stuck open. Or worse, it’s stuck closed. This isn’t just an inconvenience; it’s a security breach and a tenant satisfaction nightmare. You’ve likely cleared rocks from a track or wiped dust from a sensor yourself, but what’s really causing these constant failures? Here are the five most common reasons we see every day.
1. Lack of Preventive Maintenance
This is the number one cause of almost every major gate failure. Your commercial gate is a workhorse, cycling hundreds of times a day. That heavy use creates constant wear. You’ll see this as grinding noises, jerky movements, or the gate stopping halfway.
Here in Arizona, the climate makes it worse. The intense heat bakes lubricant off hinges and chains. Our fine desert dust blows in, mixing with what’s left to create an abrasive sludge that grinds down the metal. This is a problem our team at Western Gate Automation (a Western Fence company) sees constantly. Industry data shows every dollar invested in preventive maintenance saves $3 to $4 in future repairs. That’s exactly what our professional service plans, like our “Always On” maintenance program, are designed to do: clean those parts and lubricate them before they burn out the motor.
2. Bad Photo Eyes or Loop Sensors
These are your gate’s “senses.” Photo eyes shoot an invisible beam across the lane, and loop sensors in the pavement detect vehicles. When they fail, the gate usually refuses to close, leaving your property wide open.
This is a perfect storm in Arizona. A single spider web, a coating of dust from a haboob, or a splash of mud from a landscaper is enough to block a photo eye lens. The intense sun also degrades the plastic housings, letting in moisture and pests. You can wipe these sensors clean, but it’s a constant and annoying task. That’s why our “Always On” maintenance plan includes a check and cleaning of all sensors on every single visit. We take that task off your plate so you can focus on your property.
3. Obstructions in the Track
This is a simple one for sliding gates. The gate moves along a metal track on the ground, and it doesn’t take much to stop it. You’ll see the gate stop suddenly or hear a loud clunk or grinding sound.
The main culprits are gravel from xeriscaping, wind-blown sand, or small pebbles. After a monsoon, that debris turns into a hard-packed mud that can jam the rollers and burn out the motor. You can clear these rocks, but a professional service includes a full track inspection and cleaning to prevent the damage these small obstructions can cause.
4. Electrical Issues
The electrical system is the gate’s nervous system. When it has a problem, the gate may be completely dead, or it will work only some of the time.
Monsoon storms are the primary enemy here. A nearby lightning strike can send a power surge that fries wires or heavy rain can flood underground junction boxes. The biggest problems in Arizona are the pests. Ants and geckos are drawn to the warmth of control boxes and keypads, where they often walk across circuit boards and short them out.
This is where a quick fix fails. You need a technician who understands both the electrical systems and the physical gate. This is why our in-house team at Western Gate Automation is different. We’re a single-source solution, handling the automation, fabrication, and fencing. This means our customers only have to make one call. Our techs can diagnose the whole problem, not just one part of it.
5. Control Board Failures
If the electrical system is the nerves, the control board is the gate’s brain. It’s the complex circuit board inside the main operator box that receives signals from remotes and sensors and tells the motor what to do. When it fails, the gate acts erratically.
It may open on its own, stop in random places, or just die completely. It may not respond to remotes or keypads at all.
The number one killer of control boards is heat. A metal operator box sitting in the full Arizona sun can reach internal temperatures that bake the sensitive electronics. This drastically shortens the control board’s life. These failures, especially the electrical ones, are not simple DIY fixes and often require a professional diagnosis.
As a property manager in the Phoenix area, you have enough to deal with. You can’t prevent every unexpected failure, but you can be prepared. This is why our service is built around proactive prevention and immediate response. Our proactive maintenance plans are designed to stop these common Arizona failures before they happen. Our 24/7 support team provides the immediate response when the unexpected does occur. The team at Western Gate Automation and Western Fence specializes in building and maintaining systems that withstand the local climate.
