Algolaser DIY Kit Alarm Status

can anybody guide me how to unlock alarm status in algolaser diy kit

You just have to press the reset button under the control panel

When i want to start up my Algolaser DIY Kit, the push-on button keeps on flickering and makes a beeping sound. So i’ve opened the cold case and pushed the reset button,but the machine just shuts down and when i push the start button again,it starts flickering and beeping again. So,now i don’t know what the problem is. It never did that before. Any solutions?
