Theo, the dfc light in the elevator is always on. What happened?

The elevator can't be closed normally. The reason why the DFC light of ofo elevator is always on is to detect the condition of the internal system of the elevator. The reason is that the elevator door can't be closed normally or gets stuck in the process of closing. If the DFC light is on, it is necessary to check whether the elevator door is closed normally and whether there are foreign objects blocking the door's closing. If there is any problem, contact the property or maintenance personnel in time to ensure safety. Elevator refers to mechanical and electrical equipment that is driven by power and uses boxes running along rigid guide rails or steps running along fixed lines to lift or transport people and goods in parallel.
