Few things are more frustrating than an automatic door that suddenly refuses to open—especially during business hours or peak traffic.
In most cases, these failures aren’t caused by the door itself… but by power supply issues or dying backup batteries that went unchecked for too long.
Even the best systems depend on reliable, clean, and uninterrupted power. Here’s how to make sure yours never lets you down:
- Test Batteries Quarterly
If your door uses backup or low-voltage batteries, check their voltage output and replace them every 12–18 months—before they fade. - Inspect Power Supply Units
Dust, vibration, and heat can shorten their life. A quick voltage check ensures consistent performance. - Verify Emergency Backup Functionality
Power loss events should trigger safe default door positions. Test these systems regularly. - Check Wiring Connections
Loose or corroded terminals can create intermittent power drops—one of the most common service call issues.
5. Document Replacement Dates
A simple label with the last replacement date saves guesswork and ensures timely changeouts.
