How to Fix an Automatic Door That's Making a Loud Noise

Automatic doors are a convenient and efficient way to allow people to move in and out of a building. However, when an automatic door starts making a loud noise, it can be a nuisance and potentially a safety hazard. The good news is that there are several things you can do to fix a noisy automatic door. Here's what you need to do:

Step 1: Identify the Type of Noise

The first thing to do when your automatic door is making a loud noise is to identify the type of noise. Is it a grinding noise, a squeaking noise, or a rattling noise? Each type of noise can indicate a different issue with your automatic door, so it's important to know what you're dealing with before you start troubleshooting.

Step 2: Check the Track

One of the most common causes of a noisy automatic door is a dirty or damaged top roller track or bottom guide track. Over time, dirt and debris can accumulate on the track, causing the rollers or guides to make a grinding noise as they move along it. Additionally, if the track is damaged, the rollers or bottom guides may make a rattling noise as they move over the uneven surface. Inspect the track for any damage and clean it thoroughly with a soft cloth or brush. In some cases replacing the top roller track or bottom guide track may be necessary.

Step 3: Lubricate the Rollers

If the track is not the issue, the problem may be with the top rollers or bottom guides. Over time, the top rollers or bottom guides can become dirty or worn, causing them to make a squeaking noise as they move along the track. Lubricate the roller bearings or bottom guide bushings with a silicone spray or similar lubricant to help reduce the noise. Be sure to use a lubricant that is safe for use on automatic doors. If the bearing in the top rollers or the bushing in the bottom guide is worn out, the top roller or bottom guide should be replaced. Remember, if you need to replace one roller or bottom guide, be sure to replace them all on the automatic door. Chances are if one roller or bottom guide has broken, the other bearings and/or bushings in the other rollers or bottom guides are also worn down. Replacing only one component will put unweeded stress on it since other components in the system are worn.

Step 4: Check the Motor and Controller

If the track and rollers are not the issue, the problem may be with the motor. A noisy motor can make a variety of different sounds, from a grinding noise to a rattling noise or hum. Check the motor to make sure that it is working properly. A grinding noise could be the coupling that joins the motor to the gearbox. A rattling noise could be a loose motor mount. While an excessive humming sound could indicate a bad motor. If the motor is not functioning correctly, it may need to be repaired or replaced. If you notice a humming noise from the control board, that could indicate a grounded motor.

Step 5: Tighten Loose Parts

If the noise is coming from loose parts, you may be able to fix the issue by tightening them. Check all of the screws and bolts on your automatic door to make sure that they are tight. Loose parts can cause a rattling or clanking noise as the door moves, so tightening them can help to reduce the noise.

Step 6: Call a Professional

If you have tried all of these steps and your automatic door is still making a loud noise, it may be time to call a professional. An experienced technician can diagnose the problem and make the necessary repairs to get your door working properly again.
