Will blocking the elevator door burn out parts?

No. Blocking the elevator door will not directly cause the parts to burn. The elevator system is designed with safety devices and protective measures to prevent serious failure or damage caused by blocked doors. When the elevator door is blocked, the elevator will detect resistance or abnormal situation and automatically trigger the safety device. These safety devices can include elevator door sensors, pressure sensors, anti-pinch devices, etc. This will stop the elevator system to protect the safety of passengers.
