If there is no reading on the LED screen, meaning that the screen is blank or dark, and you are not getting any LED lights on, it is likely that either there is no power going in to the Control Module, or that its internal fuse has tripped. A qualified person can follow the no power troubleshooting found on the Universal-series support page. If needed, you can contact customer service for additional support. Please let us know what other questions you might have.
