The common automatic gate problems we see include: dirty sensors, worn chains or belts, failed motors or capacitors, hinge or track misalignment, blocked tracks, remote or keypad interference, electrical damage, slow motion, and grinding noises. Each has a quick troubleshooting step, but all require safe inspection under UL 325 and ASTM F2200 .
Fixing any issue must be the top priority as soon as there is an incident or a first indication of improper conduct. A prompt response can actually lower money outlay and damage caused. In this guide, HerpTec experts explain practically all of the main issues that electric gate owners experience to give you a preliminary diagnosis of failures that may occur.

One of the gate’s weaknesses is the electric gate mechanism that opens and closes the gate. The failures of the electrical engine are the real cause of the majority of issues with activating the gates. The engine has a maximum lifespan that must be kept in mind; after ten years of continuous usage, the engine’s operation is disrupted by natural wear and tear.
A skilled specialist who is acquainted with the mechanism is actually necessary for engine breakdowns. Old engines can sometimes be fixed, but in the majority of cases, the only option will be to replace the old engine with a new one.
Automatic Gate Track
Quick check: Clean the small photo-eye sensors near the bottom rail.
Dust, rain, fog, or cobwebs block the beam and stop the opener from closing. UL 325 rules forbid bypassing sensors because it risks injury. If cleaning doesn’t fix the problem, schedule a same-day fix.
Quick check: Look for rust or loose tension on the drive chain or belt.
A chain or belt that slips creates loud grinding noises and reduced functionality. Running the opener in this state can cause permanent damage to sprockets. HeroTec performs on-site inspections and immediate repairs.
Quick check: If the motor hums but won’t move, the capacitor may be bad.
A failed capacitor prevents the gate from starting its cycle. Heat and power surges are the main causes. Replacing this component safely requires licensed troubleshooting and compliance with ASTM F2200.
Quick check: Look for a gate leaning off its track or sticking at its hinges.
In hillside areas, soil shifts after rain and knocks gates out of line. Misalignment puts strain on the opener and can crack welds. Only a local company with welding skills should fix this issue.
Quick check: Shine a flashlight down the track to spot rocks or toys. Use a garden broom to clean up.
Stones, sticks, leaves, or other debris disrupt smooth travel. These common gate issues also make the opener reverse mid-cycle. Clearing the track may restore functionality, but bent rollers or damaged guides require professional repairs.
Quick check: Replace the CR2032 battery or re-sync the keypad.
If the wall button works but the remote fails, signal interference or worn wiring may be the problem. Chamberlain and LiftMaster supportshows how to reprogram keypads and remotes when this issue occurs. If interference continues, HeroTec replaces faulty receivers.
Quick check: After storms, look for burn marks inside the control box.
Lightning or a power failure often damages electrical connections and circuit boards. UL-listed surge arrestors prevent repeat malfunctions, but replacing boards requires certified systems training. HeroTec technicians carry factory parts for fast repairs.
Quick check: Test the backup battery if the gate only moves halfway.
Corroded terminals or weak batteries cause slow travel and partial failures. Coastal neighborhoods like Santa Monica see more gate issues due to salt fog. HeroTec restores full functionality with fresh parts and complete inspection.
Quick check: Listen for squealing or scraping sounds.
Lack of grease, dry rollers, or loose chains creates grinding. While lubrication may provide a short fix, the underlying problem often worsens. HeroTec’s Clean-Leave Standard means every fix includes lubrication, alignment, and a safety inspection.
If the electric gate cannot be opened, or if it’s unexpectedly not closed or cannot be operated, there may be a problem with the Logic board. The technician’s knowledge of the control panel and typical issues is mostly what determines whether the issue can be fixed. When an existing board is repairable, it can be fixed. However, when a board cannot be fixed, a replacement must be made.
