Common Problems with Electric Gates (and How to Fix Them)

by Cape Smart Automation

On July 31, 2025

Electric gates are one of the best ways to secure your property, until they stop working.

Whether it’s after heavy rain or just out of the blue, these issues can leave you stuck outside or forced to leave your gate open.

If you’re searching for electric gate troubleshooting tips or wondering why your electric gate is not working after rain, you’re in the right place.

1. Why Do Electric Gates Stop Working?

There are a few common problems with electric gates that come up again and again:

Power supply issues: No electricity = no movement. Always check if the motor is getting power first.
Remote control problems: Sometimes the issue is as simple as a flat battery or interference.
Physical obstructions: Something small like a rock, twig, or even sand in the track can stop the gate from moving.
Gate motor faults: These could include burnt-out motors, damaged limit switches, or worn gears.

If none of these seem to be the issue, it might be time to look at what happened before the problem started, like the weather.

2. Electric Gate Not Working After Rain?

This is one of the most frequent gate issues we deal with in Cape Town. Moisture from rain can cause:

Short circuits in the gate motor
Waterlogged underground cabling
Sensor misalignment due to swelling or movement
Control box condensation

Tip: If your electric gate stopped working after rain, turn off the main power supply for a few minutes, then back on. Sometimes a simple reset clears the error.

If water has gotten into your motor housing or control board, though, you’ll likely need professional help. In Cape Town’s coastal climate, it’s a good idea to have your gate electronics checked at least once a year.

3. Electric Gate Troubleshooting: Where to Start

Before calling in the pros, try this quick electric gate troubleshooting checklist:

Is the gate motor getting power?
Does the remote work with other gates?
Is there anything blocking the track or wheels?
Do the sensors have a clear line of sight?
Did it recently rain or flood near the gate?

If all of these seem fine, then the issue might be electrical or mechanical, and you’ll need expert help to avoid damaging the system further.

4. When to Call a Technician

If your gate is completely unresponsive, making strange noises, or opens part-way and stops, don’t force it.

Forcing a stuck gate can damage the motor or strip internal gears.

Rather call in a gate automation specialist.
