Problem:

The display used to turn off after a while. Now it stays on all the time.

Quick test:

The original design is that the display will automatically turn off after 30 seconds of no operation.

The conditions for the display to be on are - the refrigeration door needs to be opened or the display panel needs to be touched.

Please check and confirm the following information:

1. The display panel has been constantly on. Is there a door opening alarm?

2. If there is no alarm, is the display panel accidentally touched or is it faulty?

3. The main control board needs to be bent at the edge. Please confirm if it has been bent J1.
