Adec Dental Chair Won’t Turn On: Troubleshooting Guide

Adec dental chair won't turn on [2023]


As a dental practitioner, your dental chair is your most valuable and essential tool. It allows you to provide the best quality dental services to your patients. However, what if your Adec dental chair won’t turn on? This can be frustrating, especially if you have patients waiting for you. In this article, we will guide you on how to troubleshoot your Adec dental chair and fix the problem.

Check the Power Source

The first and easiest step is to check the power source. Ensure that your dental chair is plugged into a working power outlet. Sometimes, a loose plug may cause your dental chair not to turn on. If the chair is plugged in, try plugging in another device to the same outlet to see if there’s power.

Check the Circuit Breaker

If the power source is not the issue, check the circuit breaker. It could be that the circuit breaker has tripped, preventing the electrical supply from reaching the dental chair. Look for the circuit breaker box and check if any of the switches have tripped. If so, reset it and check if the dental chair turns on.

Check the Foot Control

Sometimes, the problem may not be with the power source or circuit breaker, but the foot control. The foot control is responsible for turning on and off your dental chair. Check if there’s any damage to the foot control or if it’s not connected correctly. Try to reconnect or replace the foot control to see if it solves the problem.

Check the Power Cord

Another possible issue could be a damaged power cord. Check if the power cord has any visible damage, such as cuts or frays. If it does, unplug the dental chair and replace the power cord.

Check the Fuse

If the power source, circuit breaker, foot control, and power cord are all in good condition, check the fuse. The fuse is responsible for protecting the dental chair from electrical surges. If the fuse is blown, replace it with a new one.

Check the Transformer

If none of the above steps worked, the problem could be with the transformer. The transformer is responsible for converting the voltage from the power source to the voltage required by the dental chair. Check if the transformer is faulty or damaged. If so, you need to replace it.

Call a Professional

If you have tried every troubleshooting step and the dental chair still won’t turn on, it’s time to call a professional. A trained technician can diagnose the problem and fix it for you. It’s essential to seek professional help to avoid further damage to your dental chair.


Adec dental chairs are known for their reliability and durability. However, like any other electronic device, they can also malfunction. If your Adec dental chair won’t turn on, follow the troubleshooting steps we have outlined above. Remember to seek professional help if the problem persists.
