Screen Separator machine continuously beeps and displays LLL.

Hi, I purchased a new screen separator heating machine. After 2 days of working, When i switch it ON, It displays "LLL" instead of temperature increasing and beeps continuously. I have tried setting different temp. but still no luck. What is wrong with the machine? or am i missing something. Can someone guide me please.

Hi @hussain8830,

What is the make and model number of the screen separator heating machine as you have selected a mobile phone as the device?
