Electronics Repair Questions? Ask an Electronics Technician
Hi, Wayde here. I'll be glad to help you with this issue.
If the door is making a buzzing sound, and the door latch will not release, then usually this means the electro magnetic striker is jamned. You might want to visually inspect it to see if is bent, or needs lubricant. If you lubricate it, use only graphite spray.
Can you give me any other details ?
