Reasons Your New Automatic Doors Aren’t Working Properly
Just had automatic doors installed on your commercial property, but they aren't working correctly? There could be a handful of reasons for this; some due to improper installation, others due to more mundane issues that are easy to fix. Here are the most common culprits so you can get to the bottom of what's going wrong.
The Sensor Placement Is Off
Automatic doors rely on sensors to detect motion and trigger the open cycle. If a sensor is mounted too high, too low, or at the wrong angle, it won't pick up movement the way it should.
A misaligned sensor can cause the door to open too late, not open at all, or stay open longer than it needs to. The coverage zone the sensor creates has to match the traffic pattern in front of the door. If it doesn't, the door behaves erratically even when everything else is installed correctly.
The Door Hasn't Been Calibrated Yet
It could be that the door itself is fully functional. It just hasn't been calibrated, so it's not behaving as expected. Calibration is important after door installation because, without it, the door's open and close speeds, sensor sensitivity, and hold-open timing are all working from factory defaults that weren't set for your specific entryway.
Calibration adjusts those settings to match the actual dimensions of your opening and the flow of foot traffic you're working with. Skipping it is one of the most common reasons a new door acts up right out of the gate.
There's an Obstruction in the Track
Automatic sliding doors run on a track, and that track needs to stay clear. Even a small piece of debris can cause the door to stutter, slow down, or stop mid-cycle.
Check the track along the floor and the overhead rail. If the door is dragging or hesitating at a specific point in its travel, something physical is likely interfering with the movement.
The Power Supply Has a Problem
Automatic doors need a consistent power supply to operate reliably. If the door is opening inconsistently or not responding at all, the issue could be upstream from the door itself.
A loose wire connection, a tripped breaker, or an inadequate power draw from the circuit can all cause erratic behavior. If the door worked at first and then started acting up, check the circuit first.
The Installation Left Something Loose
New installations involve a lot of components, and occasionally something doesn't get fully secured. A loose bracket, an improperly seated motor mount, or hardware that wasn't torqued to spec can all affect how the door moves.
If you hear grinding or rattling as the door travels, have a technician check the hardware connections. They can inspect the brackets, motor mount, and related hardware to confirm each part sits where it should.
Rule Out the Easy Stuff First
Automatic doors not working correctly? It may not be a serious problem. Sensor placement, calibration, and track obstructions are all fixable without major repairs. Start with the straightforward possibilities, and if none of those pan out, bring in a technician to check the power supply and hardware before assuming the door itself is defective.
