How to fix a Cooper Control Panel when the display will not turn on?
- KKevin JenkinsAug 3, 2025
If the display on your Cooper Control Panel isn't turning on, there are several potential causes: * There may be no power to the control panel. If this is the case, connect the power. * The neon lamp on the power supply should be on. If it isn't, connect the plug. * The cable to power supply P12 might not be connected. Inspect all cables to ensure they are properly connected. * The cables could be incorrectly attached or damaged. Inspect all cables for damage and correct connections.
